Gitea

Gitea is a self-hosted Github clone. It is written in Go, and provides a web interface and an API to interact with an instance of a git server.

Gitea manages its own database, so to get data in and out of Gitea, use its dump and load functionality (more below).

This page describes how the Gitea container is configured.

Configuring Docker Container

To run gitea, we use a stock Gitea container image. We set several options in the docker configuration:

• USER_UID and USER_GID are set to 1000 (this avoids some problems with files that would otherwise be owned by root)

• Set restart: always to restart the container when there is a failure

  stormy_gitea:
    image: gitea/gitea:latest
    environment:
      - USER_UID=1000
      - USER_GID=1000
    restart: always

Gitea Volumes

The Gitea container stores all of its data in /data/ inside the container.

When the container is launched, the custom/ directory in the docker/d-gitea repository is mounted to /data/gitea/, which is the directory that contains the files that are used to control the way that Gitea pages look. These contain HTML templates used to render different views in Gitea and templates in custom/ will override the default Gitea page templates.

A docker volume named stormy_gitea_data is also created and mounted at /data/. This is a persistent volume that will survive even if the container is shut down.

    volumes:
      - "stormy_gitea_data:/data"
      - "./d-gitea/custom/conf/app.ini:/data/gitea/conf/app.ini"
      - "./d-gitea/custom/public:/data/gitea/public"
      - "./d-gitea/custom/templates:/data/gitea/templates"

Gitea Ports

Gitea provides both SSH and HTTPS interfaces, as it has its own built-in web server and SSH server, as well as git server.

The server that is hosting the Gitea container and this Docker pod already has an SSH server listening on port 22, so Gitea listens for SSH connections externally on port 222.

    ports:
      - "222:22"

Note that this bypasses our d-nginx-charlesreid1 nginx container entirely and allows clients to connect to Gitea directly.

The Gitea server listens for HTTP/HTTPS connections on port 3000, but that is by default only listening on the internal Docker network, which is exactly how we want it. We want all HTTP and HTTPS traffic to be handled by the front-end d-nginx-charlesreid1 container, and it will reverse-proxy HTTP/HTTPS requests to the Gitea container.

Gitea Configuration Files

app.ini is the name of the configuration file used by Gitea. An example app.ini configuration file is contained in the docker/d-gitea repository, as well as a script to make a configuration file.

    volumes:
      - "stormy_gitea_data:/data"
      - "./d-gitea/custom/conf/app.ini:/data/gitea/conf/app.ini"
