5 = Basic installation =
6
7 To setup a gitea server using docker, the following docker-compose.yml file shall be used:
8
9 {{code language="yaml"}}
10 version: '2'
11
12 networks:
13 gitea:
14 external: false
15
16 services:
17 web:
18 image: gitea/gitea:latest
19 environment:
20 - USER_UID=1002
21 - USER_GID=1002
22 volumes:
23 - ./data:/data
24 - /home/git/.ssh/:/data/git/.ssh
25 ports:
26 - "3000:3000"
27 - "2200:22"
28 depends_on:
29 - db
30 restart: always
31 networks:
32 - gitea
33 db:
34 image: mariadb
35 restart: always
36 environment:
37 - MYSQL_ROOT_PASSWORD=<redacted>
38 - MYSQL_DATABASE=gitea
39 - MYSQL_USER=gitea
40 - MYSQL_PASSWORD=<redacted>
41 volumes:
42 - ./db/:/var/lib/mysql
43 networks:
44 - gitea
45 {{/code}}

47 What the above docker-compose configuration will do is that it will, in essence, create two, always on, services, that will forever be restarted: a mariadb database server that will write all of its data to a local "db" directory, and another web service that will server as the main git server and the web server alongside it.
48
49 Before starting the docker services, please create the necessary resources first.
50
51 = Create the required local directories to store the data in =
52
53 Do a simple command to create the necessary directories:
54
55 {{code language="bash"}}mkdir data db{{/code}}
56 Backing up just these two directories should, in theory, be enough to allow for full restoration of all git repository resources into the future. **WARNING: This has not been tested yet!!!**
57
58 = Create a separate git user to login into via SSH =
59
60 Creating a separate user, technically, is unnecessary, but it makes the configuration more conventional.
61
62 {{code language="bash"}}
63 useradd -m -u 1002 git
64 {{/code}}
65
66 Assuming the 1002 UID is already assigned to a different user, feel free to use a different UID (**be sure to update the yaml configuration with the proper user ID, then**).
67
68 Once this configuration has been done, go ahead and generate an /home/git/.ssh/ directory for the user to have. Be sure to chown this specific directory to the git user as appropriate:
69
70 {{code language="bash"}}
71 chown git:git -R /home/git/.ssh/
72 chmod 700 /home/git/.ssh/
73 {{/code}}
74
75 Once all these steps are done, you can proceed to the next step.
76
77 = Spin up a container from the docker image =
78
79 {{code language="bash"}}
80 docker-compose up -d
81 {{/code}}
82
83 Had all the necessary steps been done properly, this should yield a fully functional container. If there are any errors encountered by this point, please fix them before proceeding.
84
85 = Set up a proper nginx endpoint for the docker service =
86
87 Deploy the following configuration to make the container accessible to the outside world:
88
89 {{code language="nginx"}}
90 server {
91 server_name git.transistor.one;
92
93 listen [::]:443 http2 ssl; # managed by Certbot
94 listen 443 http2 ssl; # managed by Certbot
95 # http2 on;
96
97 include /etc/nginx/snippets/ssl.conf;
98
99 location / {
100 proxy_pass http://localhost:3000;
101 }
102 }
103 {{/code}}
104
105 Once this is done, restart nginx:
106
107 {{code language="bash"}}
108 systemctl restart nginx
109 {{/code}}
