Time for version control

How would I share my projects with you, if I do not have any git hosting server? I don’t know…

That is a reason, why we need to set up one! You can choose from more variant, but I decided for Gitea .

Self-hosting Gitea

Thanks to our earlier setup, next step is pretty simple.

All what we need to do is expand our docker setup, but I will do one more step, because we will need to share network between docker containers, I will add one more layer of docker compose, for holding the networks alive.

That said, I will continue with setup from last article about setting up whole server and WireGuard.

Change docker layout

Let’s start with stopping our containers for a while (execute commands in same folder as docker compose).

docker compose down

Create new folder for all the files, for example web and move all files into it.

mkdir web
mv * web

Now create new docker-compose.yml file with following content:

networks:
  proxy_network:

include:
  - web/docker-compose.yml

What you can see is, that we used same network as in docker-compose.yml file, and included it. We will add all future docker-compose.yml files here. Thanks to that we can control all containers by one command and share network between them, without need to manually create persistent docker networks.

You can start containers again by:

docker compose up -d

And you should be back online.

Add Gitea to stack

Create new directory gitea for Gitea and it’s data an into it create new docker-compose.yml file with following content:

networks:
  gitea_internal:
  proxy_network:

services:
  gitea:
    image: docker.gitea.com/gitea:latest
    container_name: gitea
    environment:
      - USER_UID=${APP_UID}
      - USER_GID=${APP_GID}
      - GITEA__database__DB_TYPE=postgres
      - GITEA__database__HOST=gitea_db:5432
      - GITEA__database__NAME=${DB_NAME}
      - GITEA__database__USER=${DB_USER}
      - GITEA__database__PASSWD=${DB_PASSWORD}
    restart: always
    networks:
      - gitea_internal
    volumes:
      - ./gitea:/data
      - /etc/timezone:/etc/timezone:ro
      - /etc/localtime:/etc/localtime:ro
    ports:
      - "3000:3000"
      - "222:22"
    depends_on:
      - db

  gitea_db:
    image: docker.io/library/postgres:14
    restart: always
    environment:
      - POSTGRES_USER=${DB_USER}
      - POSTGRES_PASSWORD=${DB_PASSWORD}
      - POSTGRES_DB=${DB_NAME}
    networks:
      - gitea_internal
    volumes:
      - ./postgres:/var/lib/postgresql/data

And create file .env with secrets:

DB_NAME=gitea
DB_USER=gitea_user
DB_PASSWORD="super secret password"

APP_UID=1000
APP_GID=1000

Note that we specified proxy network in compose file but did not use it yet. That is because we will do first Gitea setup locally and after that we will connect it to our web.

Now you can cd .. to upper directory and add new docker-compose.yml to upper docker-compose.yml. Just add following line:

  - gitea/docker-compose.yml

Now you can start Gitea by docker compose up -d.

After that, Gitea should be online. You should visit it, by going to local_ip_address_of_server:3000 and finish first setup. This step is just up to you.

When you finish initial setup, we can add Gitea to our stack. Start by editing Gitea docker-compose.yml.

There you should remove line with ports and port definition under Gitea service and add proxy network under networks. Changed part of the file should look like this:

  gitea:
    image: docker.gitea.com/gitea:latest
    container_name: gitea
    environment:
      - USER_UID=${APP_UID}
      - USER_GID=${APP_GID}
      - GITEA__database__DB_TYPE=postgres
      - GITEA__database__HOST=gitea_db:5432
      - GITEA__database__NAME=${DB_NAME}
      - GITEA__database__USER=${DB_USER}
      - GITEA__database__PASSWD=${DB_PASSWORD}
    restart: always
    networks:
      - gitea_internal
      - proxy_network
    volumes:
      - ./gitea:/data
      - /etc/timezone:/etc/timezone:ro
      - /etc/localtime:/etc/localtime:ro
    depends_on:
      - gitea_db

Last step is to change Caddyfile in web folder. All you need to do is add following lines:

git.jirkabuilds.dev {
    reverse_proxy gitea:3000
}

If you have set up DNS correctly, after shutting the stack down and up the Gitea should be online.

And that’s it!
