00:00:00,320 --> 00:00:02,159
hi I'm Alex from tailscale and in

2
00:00:02,159 --> 00:00:03,560
today's video I'm going to show you how

3
00:00:03,560 --> 00:00:06,319
to use image a self-hosted photo backup

4
00:00:06,319 --> 00:00:08,719
solution and share that with friends and

5
00:00:08,719 --> 00:00:10,920
family let's say you've just taken a big

6
00:00:10,920 --> 00:00:12,480
trip and you want to share all the

7
00:00:12,480 --> 00:00:14,519
pictures that are on your hard drive

8
00:00:14,519 --> 00:00:16,160
with your family that lives somewhere

9
00:00:16,160 --> 00:00:19,199
else while using tail scale and caddy a

10
00:00:19,199 --> 00:00:21,199
reverse proxy in today's video I'm going

11
00:00:21,199 --> 00:00:24,160
to show you how to do just

12
00:00:24,160 --> 00:00:27,880
that all right so who is this video for

13
00:00:27,880 --> 00:00:29,519
well it's for those of you that already

14
00:00:29,519 --> 00:00:31,800
have self-hosted Services running I'm

15
00:00:31,800 --> 00:00:33,760
not going to cover how to set up image

16
00:00:33,760 --> 00:00:35,640
or audio bookshelf or anything like that

17
00:00:35,640 --> 00:00:38,040
in this video but what I am going to do

18
00:00:38,040 --> 00:00:39,480
and there'll be chapter markers down

19
00:00:39,480 --> 00:00:42,600
below is cover how to set the remote

20
00:00:42,600 --> 00:00:45,039
person portion up so you could share

21
00:00:45,039 --> 00:00:47,120
this video with the relative or with the

22
00:00:47,120 --> 00:00:49,399
friend and say follow these steps in

23
00:00:49,399 --> 00:00:51,680
this video download tail scale in this

24
00:00:51,680 --> 00:00:53,960
way and this is how you as the remote

25
00:00:53,960 --> 00:00:55,879
person can actually go about getting

26
00:00:55,879 --> 00:00:58,559
access to the service that I am hosting

27
00:00:58,559 --> 00:01:00,160
if you do need a helping hand setting up

28
00:01:00,160 --> 00:01:01,600
these applications there are some links

29
00:01:01,600 --> 00:01:03,280
down below to some sample code for

30
00:01:03,280 --> 00:01:05,920
setting up jelly fin audio bookshelf as

31
00:01:05,920 --> 00:01:08,880
well as image and caddy as well but like

32
00:01:08,880 --> 00:01:10,720
I say that isn't the focus for today's

33
00:01:10,720 --> 00:01:12,720
video we're going to be focusing on tail

34
00:01:12,720 --> 00:01:15,320
scale today and specifically custom

35
00:01:15,320 --> 00:01:17,320
domain support that's the key part

36
00:01:17,320 --> 00:01:18,560
because you can share a lot of this

37
00:01:18,560 --> 00:01:20,079
stuff already just using tail scale

38
00:01:20,079 --> 00:01:22,560
serve that's built into tail scale what

39
00:01:22,560 --> 00:01:24,320
makes today's solution unique is that

40
00:01:24,320 --> 00:01:26,640
we're using caddy as a reverse proxy to

41
00:01:26,640 --> 00:01:28,360
support a domain name that you already

42
00:01:28,360 --> 00:01:31,560
own so Alex's domain.com something like

43
00:01:31,560 --> 00:01:33,000
that and so the service that we're going

44
00:01:33,000 --> 00:01:35,560
to use today is image this is basically

45
00:01:35,560 --> 00:01:37,479
a self-hosted replacement for Google

46
00:01:37,479 --> 00:01:39,960
photos any pictures I take on my phone

47
00:01:39,960 --> 00:01:42,960
get automatically backed up to image I

48
00:01:42,960 --> 00:01:45,680
can create albums I can scan for faces I

49
00:01:45,680 --> 00:01:47,840
can you know do all that kind of stuff

50
00:01:47,840 --> 00:01:50,200
that you would do on Google photos

51
00:01:50,200 --> 00:01:52,000
except for the fact the data never

52
00:01:52,000 --> 00:01:54,280
leaves my server and never leaves my

53
00:01:54,280 --> 00:01:56,280
infrastructure so taking a look at what

54
00:01:56,280 --> 00:01:57,640
we've got over here you can see that

55
00:01:57,640 --> 00:02:00,520
I've already got image running at image.

56
00:02:00,520 --> 00:02:03,479
ru. dots andstuff dodev this is a domain

57
00:02:03,479 --> 00:02:05,560
name that I own I purchased it for about

58
00:02:05,560 --> 00:02:08,919
$13 from name cheap you can buy your own

59
00:02:08,919 --> 00:02:11,720
again for that sort of1 $15 price point

60
00:02:11,720 --> 00:02:13,720
it's not too expensive to have your own

61
00:02:13,720 --> 00:02:15,840
domain name these days imit is currently

62
00:02:15,840 --> 00:02:17,720
being served through a reverse proxy

63
00:02:17,720 --> 00:02:20,239
called caddy this automatically handles

64
00:02:20,239 --> 00:02:21,840
all of my TLS certificates and

65
00:02:21,840 --> 00:02:24,280
everything like that from let's encrypt

66
00:02:24,280 --> 00:02:26,040
but I've never really liked the name

67
00:02:26,040 --> 00:02:28,519
reverse proxy it doesn't explain very

68
00:02:28,519 --> 00:02:30,360
well what it does and I thought about

69
00:02:30,360 --> 00:02:32,040
this the other day and when you walk

70
00:02:32,040 --> 00:02:34,560
into a bar there's a bartender right you

71
00:02:34,560 --> 00:02:35,879
want to buy a drink there's a bunch of

72
00:02:35,879 --> 00:02:37,560
bottles behind the bartender you know

73
00:02:37,560 --> 00:02:39,159
some whiskies some Gins that kind of

74
00:02:39,159 --> 00:02:41,280
thing and you think to yourself I want

75
00:02:41,280 --> 00:02:43,720
access to those resources behind the

76
00:02:43,720 --> 00:02:45,640
bartender well that's what a reverse

77
00:02:45,640 --> 00:02:48,360
proxy is doing you place a request you

78
00:02:48,360 --> 00:02:51,319
order a drink and the bartender or the

79
00:02:51,319 --> 00:02:53,840
reverse proxy has permission to go and

80
00:02:53,840 --> 00:02:55,959
get that resource for you on the back

81
00:02:55,959 --> 00:02:57,760
end it has the logic of knowing which

82
00:02:57,760 --> 00:03:00,319
server is able to serve that that web

83
00:03:00,319 --> 00:03:01,680
request and so what we're going to do

84
00:03:01,680 --> 00:03:03,959
today is share that reverse proxy out

85
00:03:03,959 --> 00:03:05,959
over your tail net we're going to put a

86
00:03:05,959 --> 00:03:08,840
c name into a public registra pointing

87
00:03:08,840 --> 00:03:11,920
to the ts.net entry which is your

88
00:03:11,920 --> 00:03:14,560
personal private DNS name given to your

89
00:03:14,560 --> 00:03:17,120
tailet so that it only resolves over

90
00:03:17,120 --> 00:03:19,120
your tailet you're not exposing any of

91
00:03:19,120 --> 00:03:20,560
this to the internet and that's such a

92
00:03:20,560 --> 00:03:22,920
crucial difference between doing this

93
00:03:22,920 --> 00:03:24,720
with something like port forwarding or

94
00:03:24,720 --> 00:03:26,840
firewall rules or something like that

95
00:03:26,840 --> 00:03:30,480
all of this remains completely offline

96
00:03:30,480 --> 00:03:32,239
you know that we're not exposing any of

97
00:03:32,239 --> 00:03:34,720
this to the public internet and so you

98
00:03:34,720 --> 00:03:36,400
as the administrator of the image

99
00:03:36,400 --> 00:03:38,799
instance Your Role here is to make sure

100
00:03:38,799 --> 00:03:40,959
that your reverse proxy is working so in

101
00:03:40,959 --> 00:03:42,840
our case that's caddy and then you're

102
00:03:42,840 --> 00:03:44,799
going to need to put an entry into Cloud

103
00:03:44,799 --> 00:03:47,159
flare as a public DNS record we'll come

104
00:03:47,159 --> 00:03:49,120
on to that in just a second so let's

105
00:03:49,120 --> 00:03:51,080
take a look at my tail scale admin

106
00:03:51,080 --> 00:03:52,959
console over here you can see that I've

107
00:03:52,959 --> 00:03:56,000
got a caddy node in my tailet the actual

108
00:03:56,000 --> 00:03:58,200
image service is being served through

109
00:03:58,200 --> 00:04:00,120
this auntu server down here here at the

110
00:04:00,120 --> 00:04:02,599
bottom but at the top here we've got

111
00:04:02,599 --> 00:04:04,680
caddy as the reverse proxy as another

112
00:04:04,680 --> 00:04:07,400
node on the tailet now I'm using proxmox

113
00:04:07,400 --> 00:04:09,439
underhood you can do this however you

114
00:04:09,439 --> 00:04:10,879
like but I'm going to use proxmox to

115
00:04:10,879 --> 00:04:13,560
show you today in here we can see that

116
00:04:13,560 --> 00:04:15,959
we have caddy running so if I type caddy

117
00:04:15,959 --> 00:04:18,040
for example it's installed I have it

118
00:04:18,040 --> 00:04:20,399
installed as a system D service and

119
00:04:20,399 --> 00:04:22,120
there'll be links in the description

120
00:04:22,120 --> 00:04:23,880
down below to all of the resources if

121
00:04:23,880 --> 00:04:26,320
you want to do this in an lxc container

122
00:04:26,320 --> 00:04:28,960
using systemd to run caddy as a service

123
00:04:28,960 --> 00:04:31,440
as well now if I do a tail scale status

124
00:04:31,440 --> 00:04:34,120
inside this lxc container you can see

125
00:04:34,120 --> 00:04:36,039
that it's just behaving like any other

126
00:04:36,039 --> 00:04:38,360
tail scale node on my tailet but what's

127
00:04:38,360 --> 00:04:40,120
interesting is if we take a look at the

128
00:04:40,120 --> 00:04:41,880
caddy file that I'm using by the way the

129
00:04:41,880 --> 00:04:44,320
caddy file is the way that we tell caddy

130
00:04:44,320 --> 00:04:46,400
what we want to proxy where so you can

131
00:04:46,400 --> 00:04:48,240
see here for example I've got three

132
00:04:48,240 --> 00:04:50,120
services that I'm proxying through my

133
00:04:50,120 --> 00:04:52,240
caddy instance first of all we've got

134
00:04:52,240 --> 00:04:54,160
image running on one

135
00:04:54,160 --> 00:04:56,000
192168

136
00:04:56,000 --> 00:04:58,400
111013 on Port

137
00:04:58,400 --> 00:05:01,400
2283 the the next one we've got is audio

138
00:05:01,400 --> 00:05:03,680
bookshelf this is a self-hosted audio

139
00:05:03,680 --> 00:05:05,919
book app and you can see that this one

140
00:05:05,919 --> 00:05:08,520
is actually running on the tailet IP of

141
00:05:08,520 --> 00:05:10,840
the auntu server as well and then

142
00:05:10,840 --> 00:05:12,639
finally we've got jellyfin which is a

143
00:05:12,639 --> 00:05:14,280
self-hosted media server that doesn't

144
00:05:14,280 --> 00:05:16,600
need the cloud or anything like that and

145
00:05:16,600 --> 00:05:18,759
all we're using there is the DNS name

146
00:05:18,759 --> 00:05:21,520
through tail scales magic DNS feature of

147
00:05:21,520 --> 00:05:24,840
ubu ubu 2204 D

148
00:05:24,840 --> 00:05:27,199
server now I I chose these three

149
00:05:27,199 --> 00:05:28,960
services in this way to show you the

150
00:05:28,960 --> 00:05:30,639
different way you could configure your

151
00:05:30,639 --> 00:05:33,639
caddy file using a local Lan IP address

152
00:05:33,639 --> 00:05:35,880
so this box could be something that's

153
00:05:35,880 --> 00:05:38,720
not even on your tailet for example so

154
00:05:38,720 --> 00:05:40,560
long as it's rootable from the caddy

155
00:05:40,560 --> 00:05:43,919
instance itself audio books for example

156
00:05:43,919 --> 00:05:45,919
could be any node anywhere else on your

157
00:05:45,919 --> 00:05:48,759
tail net anywhere in the world and again

158
00:05:48,759 --> 00:05:50,600
the same principle applies to jellyfin

159
00:05:50,600 --> 00:05:52,120
because it's just using the tail scale

160
00:05:52,120 --> 00:05:54,160
magic DNS name now the other thing I

161
00:05:54,160 --> 00:05:55,720
wanted to draw your attention to is at

162
00:05:55,720 --> 00:05:57,560
the top of this file is this Cloud flare

163
00:05:57,560 --> 00:06:00,319
section here this is how caddy

164
00:06:00,319 --> 00:06:03,360
automatically generates the https the

165
00:06:03,360 --> 00:06:06,120
TLs certificates for these self-hosted

166
00:06:06,120 --> 00:06:08,000
Services you can see when I do the

167
00:06:08,000 --> 00:06:10,599
import Cloud flare here it Imports that

168
00:06:10,599 --> 00:06:12,919
cloud flare token and caddy has some

169
00:06:12,919 --> 00:06:15,360
logic in it under the hood that knows oh

170
00:06:15,360 --> 00:06:17,599
he specified Cloud flare that means I'm

171
00:06:17,599 --> 00:06:19,039
going to have to go and do the Acme

172
00:06:19,039 --> 00:06:21,120
request to go and generate the TLs

173
00:06:21,120 --> 00:06:23,160
certificates automatically for cloud

174
00:06:23,160 --> 00:06:25,199
flare so what's required on the tail

175
00:06:25,199 --> 00:06:26,759
scale side okay we need to make sure

176
00:06:26,759 --> 00:06:28,479
that it's a node on our tail net okay so

177
00:06:28,479 --> 00:06:30,520
I'll do a tail scale status I've already

178
00:06:30,520 --> 00:06:32,960
done tail scale login just to save us a

179
00:06:32,960 --> 00:06:34,599
bit of time in the video now the next

180
00:06:34,599 --> 00:06:35,960
thing we're going to have to do is

181
00:06:35,960 --> 00:06:38,120
configure the public DNS side of this

182
00:06:38,120 --> 00:06:40,319
solution we're going to need to know

183
00:06:40,319 --> 00:06:43,039
where our domain names name servers are

184
00:06:43,039 --> 00:06:45,120
pointing in my case I've pointed my

185
00:06:45,120 --> 00:06:48,199
domain dots and stuff dodev I've pointed

186
00:06:48,199 --> 00:06:50,199
the name service for that domain to

187
00:06:50,199 --> 00:06:52,080
cloudflare so that I can use cloudflare

188
00:06:52,080 --> 00:06:54,919
as my public DNS entry to manage all of

189
00:06:54,919 --> 00:06:57,360
my DNS records so once you've gone ahead

190
00:06:57,360 --> 00:06:58,840
and got logged into Cloud flare it's

191
00:06:58,840 --> 00:07:00,360
going to be a case of heading over to

192
00:07:00,360 --> 00:07:03,039
the domain itself and then on the left

193
00:07:03,039 --> 00:07:05,080
hand side here you can see there's a DNS

194
00:07:05,080 --> 00:07:07,000
section just here and then the entire

195
00:07:07,000 --> 00:07:09,120
thing is configured here in one entry so

196
00:07:09,120 --> 00:07:12,919
I've got star. RDU as a wild card entry

197
00:07:12,919 --> 00:07:16,680
pointing to caddy Velociraptor hyen

198
00:07:16,680 --> 00:07:19,759
noodle fish. tsnet now you will get this

199
00:07:19,759 --> 00:07:21,960
value here the target which is required

200
00:07:21,960 --> 00:07:24,199
to create a c name you'll get that by

201
00:07:24,199 --> 00:07:26,000
heading over to your tail scale admin

202
00:07:26,000 --> 00:07:29,800
console go to DNS and whatever value is

203
00:07:29,800 --> 00:07:31,759
here whatever value is in this box here

204
00:07:31,759 --> 00:07:33,759
under tailet name in my case

205
00:07:33,759 --> 00:07:36,879
Velociraptor hyphen noodle fish. ts.net

206
00:07:36,879 --> 00:07:38,759
that's the value that you want to put

207
00:07:38,759 --> 00:07:41,280
into here this must be a fully qualified

208
00:07:41,280 --> 00:07:43,280
domain name this is because when you

209
00:07:43,280 --> 00:07:45,960
share the node to another tailet it's

210
00:07:45,960 --> 00:07:47,960
not accessible by the short name it's

211
00:07:47,960 --> 00:07:50,360
only accessible by the full fully

212
00:07:50,360 --> 00:07:53,159
qualified domain name of caddy do

213
00:07:53,159 --> 00:07:55,840
whatever. ts.net and with that done

214
00:07:55,840 --> 00:07:58,280
click save and you can verify this by

215
00:07:58,280 --> 00:07:59,759
opening a terminal window windows so

216
00:07:59,759 --> 00:08:01,120
I'll just drag this one in from over

217
00:08:01,120 --> 00:08:03,680
here and we'll do a dig what did I I

218
00:08:03,680 --> 00:08:08,440
mean i' yeah test. U do some stuff dodev

219
00:08:08,440 --> 00:08:10,319
and because this is a wild card you

220
00:08:10,319 --> 00:08:13,879
should see that we return a c name here

221
00:08:13,879 --> 00:08:17,680
for caddy do your tailet name. ts.net

222
00:08:17,680 --> 00:08:19,599
doesn't have to be caddy by the way it

223
00:08:19,599 --> 00:08:22,240
just has to match the name of the node

224
00:08:22,240 --> 00:08:24,199
in your tail scale admin console so

225
00:08:24,199 --> 00:08:26,440
again just to get that we go over to the

226
00:08:26,440 --> 00:08:28,759
tail scale admin console click on the

227
00:08:28,759 --> 00:08:30,800
drop down here and whatever this second

228
00:08:30,800 --> 00:08:32,399
entry is here this is the fully

229
00:08:32,399 --> 00:08:34,640
qualified domain name for the node

230
00:08:34,640 --> 00:08:36,719
itself all right so that was a lot have

231
00:08:36,719 --> 00:08:38,559
we got it first of all we need to know

232
00:08:38,559 --> 00:08:40,320
what our fully qualified domain name is

233
00:08:40,320 --> 00:08:43,039
for caddy the node on your tailet so we

234
00:08:43,039 --> 00:08:44,640
get that in the admin console click on

235
00:08:44,640 --> 00:08:47,560
the drop down second option over here we

236
00:08:47,560 --> 00:08:49,519
then in Cloud flare need to make sure

237
00:08:49,519 --> 00:08:51,839
that the name servers for our domain

238
00:08:51,839 --> 00:08:53,800
wherever we registered it in my case I

239
00:08:53,800 --> 00:08:55,800
registered mine at name cheep but you

240
00:08:55,800 --> 00:08:58,600
know other registar are available and I

241
00:08:58,600 --> 00:09:00,600
pointed my name service for that domain

242
00:09:00,600 --> 00:09:03,000
to Cloud flare once I'd done that and

243
00:09:03,000 --> 00:09:05,040
everything had propagated properly which

244
00:09:05,040 --> 00:09:07,600
can take a few hours by the way I simply

245
00:09:07,600 --> 00:09:09,640
went and created a new record you click

246
00:09:09,640 --> 00:09:11,880
the add record button over here click on

247
00:09:11,880 --> 00:09:14,079
the drop down see name you know I can

248
00:09:14,079 --> 00:09:16,880
blah blah blah whatever put that in and

249
00:09:16,880 --> 00:09:19,640
then my target here for example is you

250
00:09:19,640 --> 00:09:21,680
know test.

251
00:09:21,680 --> 00:09:23,920
Velociraptor that has to match the fully

252
00:09:23,920 --> 00:09:26,079
qualified domain name in your tailet

253
00:09:26,079 --> 00:09:28,800
remember and then TTL time to live I

254
00:09:28,800 --> 00:09:30,440
mean whilst I'm doing a bunch of testing

255
00:09:30,440 --> 00:09:32,839
for this video I set mine to one minute

256
00:09:32,839 --> 00:09:35,120
if you leave yours to Auto you probably

257
00:09:35,120 --> 00:09:36,680
won't have any issues so just leave that

258
00:09:36,680 --> 00:09:39,320
one alone click save and then it might

259
00:09:39,320 --> 00:09:41,120
take a moment or two to propagate but if

260
00:09:41,120 --> 00:09:44,399
I do uh what did I call it I've already

261
00:09:44,399 --> 00:09:47,120
forgotten blah blah

262
00:09:47,120 --> 00:09:51,040
blah if I do blah blah blah we should

263
00:09:51,040 --> 00:09:53,000
see that yeah there you go the C name

264
00:09:53,000 --> 00:09:56,160
now resolves to test. Velociraptor and

265
00:09:56,160 --> 00:09:57,800
so the next thing to do is to go ahead

266
00:09:57,800 --> 00:09:59,959
and share it with your relative to do

267
00:09:59,959 --> 00:10:01,519
that we head over to the tail Scout

268
00:10:01,519 --> 00:10:03,920
admin console once more click on this

269
00:10:03,920 --> 00:10:06,160
button here which says share next to the

270
00:10:06,160 --> 00:10:08,800
three dot menu and generate and copy an

271
00:10:08,800 --> 00:10:10,839
invite link once we've done that you

272
00:10:10,839 --> 00:10:12,560
share this with your friend or relative

273
00:10:12,560 --> 00:10:14,519
they can do this from a mobile device or

274
00:10:14,519 --> 00:10:16,959
a laptop doesn't really matter so long

275
00:10:16,959 --> 00:10:18,680
as it's logged into the tailet that they

276
00:10:18,680 --> 00:10:20,279
created now in terms of the

277
00:10:20,279 --> 00:10:21,920
chronological order of this video this

278
00:10:21,920 --> 00:10:23,920
is where things get a little confusing I

279
00:10:23,920 --> 00:10:25,920
wanted to create a dedicated chapter so

280
00:10:25,920 --> 00:10:27,079
that you could share this with friends

281
00:10:27,079 --> 00:10:29,360
or family and say hey go to this Tim

282
00:10:29,360 --> 00:10:31,760
stamp and play From This Moment forward

283
00:10:31,760 --> 00:10:34,200
so I'm going to skip ahead or skip back

284
00:10:34,200 --> 00:10:35,959
in time a little bit go through the

285
00:10:35,959 --> 00:10:38,000
process of creating a brand new tailet

286
00:10:38,000 --> 00:10:40,720
for your relative and then once we get

287
00:10:40,720 --> 00:10:42,639
towards the end of that chapter that's

288
00:10:42,639 --> 00:10:44,440
where this invite link part will

289
00:10:44,440 --> 00:10:46,560
actually get

290
00:10:46,560 --> 00:10:48,839
used hello and welcome to the remote

291
00:10:48,839 --> 00:10:50,800
setup part of this video I'm going to

292
00:10:50,800 --> 00:10:52,200
walk you through creating a brand new

293
00:10:52,200 --> 00:10:54,160
tailet and connecting it to that remote

294
00:10:54,160 --> 00:10:55,720
service that your friend or relative is

295
00:10:55,720 --> 00:10:58,120
trying to share with you creating a tail

296
00:10:58,120 --> 00:11:00,399
scale account is completely free head

297
00:11:00,399 --> 00:11:02,959
over to tails scale.com to get started

298
00:11:02,959 --> 00:11:04,600
once there click on the button in the

299
00:11:04,600 --> 00:11:07,079
top right which says get started and

300
00:11:07,079 --> 00:11:09,120
then you'll need to choose your identity

301
00:11:09,120 --> 00:11:11,120
provider in today's video we're going to

302
00:11:11,120 --> 00:11:14,200
use Google I've created a dedicated

303
00:11:14,200 --> 00:11:15,720
Google account just for this video

304
00:11:15,720 --> 00:11:18,480
called myoms tailet

305
00:11:18,480 --> 00:11:21,040
gmail.com nice and straightforward so

306
00:11:21,040 --> 00:11:22,560
I'm going to click on sign up with

307
00:11:22,560 --> 00:11:25,000
Google and I'm already authenticated in

308
00:11:25,000 --> 00:11:27,000
this browser session with that Google

309
00:11:27,000 --> 00:11:29,200
account so it presents me the choos an

310
00:11:29,200 --> 00:11:30,519
account option just here I'm going to

311
00:11:30,519 --> 00:11:33,279
click on that one click

312
00:11:33,279 --> 00:11:35,680
continue and easy as that we've created

313
00:11:35,680 --> 00:11:38,600
a tail scale account so let's add our

314
00:11:38,600 --> 00:11:40,240
first device I'm going to make it this

315
00:11:40,240 --> 00:11:42,480
laptop that we're using right here head

316
00:11:42,480 --> 00:11:44,320
over to tailscale

317
00:11:44,320 --> 00:11:47,120
docomo now if you're on a mobile device

318
00:11:47,120 --> 00:11:49,040
you will go to the app store for your

319
00:11:49,040 --> 00:11:51,279
device and search tail scale and

320
00:11:51,279 --> 00:11:54,000
download the app there but on a laptop

321
00:11:54,000 --> 00:11:55,880
in this case it's Mac OS we're actually

322
00:11:55,880 --> 00:11:57,519
going to go to the Mac App Store to

323
00:11:57,519 --> 00:11:59,040
download tail scale click on the the

324
00:11:59,040 --> 00:12:00,600
little get button or the cloud icon if

325
00:12:00,600 --> 00:12:01,760
you've already done it with this Apple

326
00:12:01,760 --> 00:12:04,600
ID like I have here download and install

327
00:12:04,600 --> 00:12:05,320
the

328
00:12:05,320 --> 00:12:07,880
application click on open and you will

329
00:12:07,880 --> 00:12:09,880
see up here in the menu bar we now have

330
00:12:09,880 --> 00:12:12,079
a new app this is where we'll log in so

331
00:12:12,079 --> 00:12:13,480
I'm going to go ahead and just check the

332
00:12:13,480 --> 00:12:15,880
toggle box here which is going to turn

333
00:12:15,880 --> 00:12:17,279
tail scale on and then I'm going to

334
00:12:17,279 --> 00:12:19,920
click the login button now we should be

335
00:12:19,920 --> 00:12:21,639
familiar with this page by now but this

336
00:12:21,639 --> 00:12:23,480
is the sign in with Google this is where

337
00:12:23,480 --> 00:12:25,760
we use the same Google account that we

338
00:12:25,760 --> 00:12:27,600
used to create the tailet in the

339
00:12:27,600 --> 00:12:30,120
previous step

340
00:12:30,120 --> 00:12:31,720
once you click that button we're going

341
00:12:31,720 --> 00:12:33,279
to be presented with a screen here which

342
00:12:33,279 --> 00:12:35,199
says do you want to connect this device

343
00:12:35,199 --> 00:12:36,959
this laptop do you want to connect this

344
00:12:36,959 --> 00:12:39,360
device to your tailet and then once you

345
00:12:39,360 --> 00:12:40,920
click on the big blue button to say

346
00:12:40,920 --> 00:12:43,199
connect my device it's going to take you

347
00:12:43,199 --> 00:12:46,040
to your admin console this is where you

348
00:12:46,040 --> 00:12:48,120
will see all of the different devices on

349
00:12:48,120 --> 00:12:50,680
your tailet and this is the point where

350
00:12:50,680 --> 00:12:53,000
if someone sent you an invite link we'd

351
00:12:53,000 --> 00:12:55,000
now click on that invite link and add

352
00:12:55,000 --> 00:12:57,920
that shared node into this tail net so

353
00:12:57,920 --> 00:12:59,440
I'm going to go and pretend to be the

354
00:12:59,440 --> 00:13:01,160
friend or relative that's sharing this

355
00:13:01,160 --> 00:13:03,040
service with you for just a second and

356
00:13:03,040 --> 00:13:05,079
generate an invite link I go over to the

357
00:13:05,079 --> 00:13:07,399
share button here generate and copy an

358
00:13:07,399 --> 00:13:09,800
invite link what you will see as the

359
00:13:09,800 --> 00:13:11,920
remote person is an invite link that

360
00:13:11,920 --> 00:13:13,639
looks something like this login.

361
00:13:13,639 --> 00:13:17,320
tailscale doccom slash admin SL invite

362
00:13:17,320 --> 00:13:19,320
and then a string of characters when you

363
00:13:19,320 --> 00:13:21,079
put that into a web browser or click on

364
00:13:21,079 --> 00:13:23,440
it on a mobile device some magic will

365
00:13:23,440 --> 00:13:25,040
happen and we will ask you if you want

366
00:13:25,040 --> 00:13:26,959
to have this shared device added to your

367
00:13:26,959 --> 00:13:28,959
tailet I'm going to click on the button

368
00:13:28,959 --> 00:13:31,399
here which says accept invite and when I

369
00:13:31,399 --> 00:13:34,079
do you'll notice that inside your tailet

370
00:13:34,079 --> 00:13:36,120
now notice the tailet name at the top

371
00:13:36,120 --> 00:13:38,920
here my mom's tailet gmail.com you've

372
00:13:38,920 --> 00:13:41,079
now got two noes you've got your laptop

373
00:13:41,079 --> 00:13:43,760
and also the shared service that the

374
00:13:43,760 --> 00:13:45,880
other person's trying to share with you

375
00:13:45,880 --> 00:13:47,560
what this means is if they've given you

376
00:13:47,560 --> 00:13:49,920
a website to go to so in my case here

377
00:13:49,920 --> 00:13:52,680
for this demo it's image. ru. dots and

378
00:13:52,680 --> 00:13:55,560
stuff dodev you can now access that

379
00:13:55,560 --> 00:13:58,000
service on any device that you're logged

380
00:13:58,000 --> 00:13:59,759
in with tech tail scale remember we

381
00:13:59,759 --> 00:14:01,920
logged in using the tail scale up up

382
00:14:01,920 --> 00:14:04,199
here in the corner to my mom's tail net

383
00:14:04,199 --> 00:14:06,160
and now any service that that friend or

384
00:14:06,160 --> 00:14:08,279
relative has shared with you you can now

385
00:14:08,279 --> 00:14:10,399
access on any device that you are logged

386
00:14:10,399 --> 00:14:12,440
in with tail scale on now I'm going to

387
00:14:12,440 --> 00:14:13,720
go ahead and get logged in with the

388
00:14:13,720 --> 00:14:16,279
username that the person has provided to

389
00:14:16,279 --> 00:14:18,800
me which in this case is a tail and

390
00:14:18,800 --> 00:14:21,639
scales gmail.com that's right get logged

391
00:14:21,639 --> 00:14:24,480
in and suddenly I can see my photos and

392
00:14:24,480 --> 00:14:26,079
so this is the Crux of the solution I

393
00:14:26,079 --> 00:14:27,839
can now go ahead and you know create

394
00:14:27,839 --> 00:14:30,639
albums if I want to this is a image

395
00:14:30,639 --> 00:14:32,440
specific thing not a tail scale specific

396
00:14:32,440 --> 00:14:34,079
thing of course I'm going to create an

397
00:14:34,079 --> 00:14:36,160
album called Canada 23 create a new

398
00:14:36,160 --> 00:14:38,519
shared album and image has a bunch of

399
00:14:38,519 --> 00:14:40,880
users within it for example so if you

400
00:14:40,880 --> 00:14:42,279
want to go ahead and create a bunch of

401
00:14:42,279 --> 00:14:44,040
users for your friends and family as the

402
00:14:44,040 --> 00:14:45,440
server admin you go into the

403
00:14:45,440 --> 00:14:47,440
administration section of image over

404
00:14:47,440 --> 00:14:49,600
here and just create a different user

405
00:14:49,600 --> 00:14:52,360
account within image for every user that

406
00:14:52,360 --> 00:14:55,120
you want to have their own you know view

407
00:14:55,120 --> 00:14:57,680
of the image application now earlier on

408
00:14:57,680 --> 00:15:00,399
in the video I also showed how we could

409
00:15:00,399 --> 00:15:03,320
use audio books and jelly fin as well so

410
00:15:03,320 --> 00:15:05,360
whoever shared this service with you may

411
00:15:05,360 --> 00:15:06,639
have a few other things they want to

412
00:15:06,639 --> 00:15:08,320
share with you up their sleeve and it

413
00:15:08,320 --> 00:15:10,079
should just be a case of going and

414
00:15:10,079 --> 00:15:12,680
typing in whatever URL they've given you

415
00:15:12,680 --> 00:15:16,759
so in my case RDU do doson stuff dodev

416
00:15:16,759 --> 00:15:19,839
loads an audiobook server for

417
00:15:19,839 --> 00:15:22,079
example and then if I wanted to go ahead

418
00:15:22,079 --> 00:15:23,480
and load up jelly fin which is a

419
00:15:23,480 --> 00:15:25,600
self-hosted media server again it's just

420
00:15:25,600 --> 00:15:28,440
dots and stuff dodev and you can see

421
00:15:28,440 --> 00:15:29,360
that

422
00:15:29,360 --> 00:15:30,920
we can share a whole bunch of

423
00:15:30,920 --> 00:15:34,240
self-hosted services using this method

424
00:15:34,240 --> 00:15:35,480
now what if we want to do this on a

425
00:15:35,480 --> 00:15:37,160
phone for example I want to access image

426
00:15:37,160 --> 00:15:39,199
from this iPhone right here well I need

427
00:15:39,199 --> 00:15:41,560
to install tail scale on that device I

428
00:15:41,560 --> 00:15:43,759
don't need to accept the invite more

429
00:15:43,759 --> 00:15:46,000
than once though because once we accept

430
00:15:46,000 --> 00:15:48,240
the invite into our tailet because all

431
00:15:48,240 --> 00:15:50,120
the devices are connected together with

432
00:15:50,120 --> 00:15:52,639
direct connections as part of the tailet

433
00:15:52,639 --> 00:15:55,000
grouping of devices there's no need to

434
00:15:55,000 --> 00:15:57,079
accept the invite on each device just

435
00:15:57,079 --> 00:16:00,040
once per tailet will will suffice now to

436
00:16:00,040 --> 00:16:02,000
download tail scale on the iPhone we go

437
00:16:02,000 --> 00:16:03,680
to the app store and just search for

438
00:16:03,680 --> 00:16:05,560
tail

439
00:16:05,560 --> 00:16:07,920
scale once we see it appear in the

440
00:16:07,920 --> 00:16:09,440
search results we just click on the

441
00:16:09,440 --> 00:16:12,199
little Cloud icon or get or open and if

442
00:16:12,199 --> 00:16:13,880
you're on Google Play it'll be the same

443
00:16:13,880 --> 00:16:16,240
type of deal here and then once the app

444
00:16:16,240 --> 00:16:18,399
is downloaded let's click on open to

445
00:16:18,399 --> 00:16:20,480
open the tail scale application now

446
00:16:20,480 --> 00:16:21,519
we're going to walk through the getting

447
00:16:21,519 --> 00:16:23,079
started wizard I'm going to click on get

448
00:16:23,079 --> 00:16:24,959
started yes I understand about the

449
00:16:24,959 --> 00:16:27,240
Privacy stuff I'm going to allow

450
00:16:27,240 --> 00:16:29,079
notifications and then and click on

451
00:16:29,079 --> 00:16:31,759
install VPN configuration this is so

452
00:16:31,759 --> 00:16:34,040
that tail scale can manage the VPN

453
00:16:34,040 --> 00:16:37,480
configurations on this particular iPhone

454
00:16:37,480 --> 00:16:38,839
the next thing we got to do is actually

455
00:16:38,839 --> 00:16:40,800
get logged into the tailet now I'm going

456
00:16:40,800 --> 00:16:42,440
to click on the login button and again

457
00:16:42,440 --> 00:16:44,319
I'm going to use the Google

458
00:16:44,319 --> 00:16:46,839
authentication provider using the same

459
00:16:46,839 --> 00:16:50,160
my moms tailet gmail.com Google account

460
00:16:50,160 --> 00:16:52,360
that we created earlier in the video

461
00:16:52,360 --> 00:16:54,240
again I'm going to click on the big blue

462
00:16:54,240 --> 00:16:56,079
connect button to connect this device to

463
00:16:56,079 --> 00:16:58,199
my tailet and you can see we've got all

464
00:16:58,199 --> 00:17:00,959
of our devices showing up right here as

465
00:17:00,959 --> 00:17:02,680
well as the shared node that we accepted

466
00:17:02,680 --> 00:17:05,079
the invite for in the previous step on

467
00:17:05,079 --> 00:17:07,160
the laptop remember you don't need to

468
00:17:07,160 --> 00:17:09,240
accept the invite more than once just

469
00:17:09,240 --> 00:17:12,480
once per tailet will suffice and so now

470
00:17:12,480 --> 00:17:14,439
if I go to the image app on my phone and

471
00:17:14,439 --> 00:17:16,119
log in you can see I've put the image.

472
00:17:16,119 --> 00:17:18,679
RDU address in here I'm going to log in

473
00:17:18,679 --> 00:17:20,359
with the username and password that

474
00:17:20,359 --> 00:17:22,760
whoever shared the service with me gave

475
00:17:22,760 --> 00:17:25,959
me and just like that over 5G I'm able

476
00:17:25,959 --> 00:17:28,760
to connect to image on my phone remember

477
00:17:28,760 --> 00:17:31,000
5G means I can't possibly be in the same

478
00:17:31,000 --> 00:17:32,960
building and connecting to this thing so

479
00:17:32,960 --> 00:17:34,600
I could be in England I could be in

480
00:17:34,600 --> 00:17:36,840
Japan or America right now it wouldn't

481
00:17:36,840 --> 00:17:38,280
matter as long as I had internet

482
00:17:38,280 --> 00:17:40,559
connectivity I could actually resolve

483
00:17:40,559 --> 00:17:43,000
this image service and of course on my

484
00:17:43,000 --> 00:17:45,240
laptop as well I'm able to resolve image

485
00:17:45,240 --> 00:17:47,400
over tail scale using the shared node

486
00:17:47,400 --> 00:17:49,760
technique with a custom domain that we

487
00:17:49,760 --> 00:17:52,720
just set up so this is a little taster

488
00:17:52,720 --> 00:17:54,280
of what you can do with tail scale thank

489
00:17:54,280 --> 00:17:56,480
you so much for joining me on this

490
00:17:56,480 --> 00:17:58,480
little Choose Your Own Adventure with

491
00:17:58,480 --> 00:18:00,159
friends and family with tail scale typee

492
00:18:00,159 --> 00:18:02,559
video and until next time I've been Alex

493
00:18:02,559 --> 00:18:06,158
from tail scale
