Installation with Docker

Gitea provides automatically updated Docker images within its Docker Hub organization. It is possible to always use the latest stable tag or to use another service that handles updating Docker images.

This reference setup guides users through the setup based on docker-compose, the installation of docker-compose is out of scope of this documentation. To install docker-compose follow the official install instructions.

Basics

The most simple setup just creates a volume and a network and starts the gitea/gitea:latest image as a service. Since there is no database available one can be initialized using SQLite3. Create a directory like gitea and paste the following content into a file named docker-compose.yml. Note that the volume should be owned by the user/group with the UID/GID specified in the config file. If you don't give the volume correct permissions, the container may not start.

version: "2"

networks:
  gitea:
    external: false

services:
  server:
    image: gitea/gitea:latest
    environment:
      - USER_UID=1000
      - USER_GID=1000
    restart: always
    networks:
      - gitea
    volumes:
      - ./gitea:/data
    ports:
      - "3000:3000"
      - "222:22"

Custom port

To bind the integrated openSSH daemon and the webserver on a different port, adjust the port section. It's common to just change the host port and keep the ports within the container like they are.

version: "2"

networks:
  gitea:
    external: false

services:
  server:
    image: gitea/gitea:latest
    environment:
      - USER_UID=1000
      - USER_GID=1000
    restart: always
    networks:
      - gitea
    volumes:
      - ./gitea:/data
    ports:
-      - "3000:3000"
-      - "222:22"
+      - "8080:3000"
+      - "2221:22"

MySQL database

To start Gitea in combination with a MySQL database, apply these changes to the docker-compose.yml file created above.

version: "2"

networks:
  gitea:
    external: false

services:
  server:
    image: gitea/gitea:latest
    environment:
      - USER_UID=1000
      - USER_GID=1000
    restart: always
    networks:
      - gitea
    volumes:
      - ./gitea:/data
     ports:
       - "3000:3000"
       - "222:22"
+    depends_on:
+      - db
+
+  db:
+    image: mysql:5.7
+    restart: always
+    environment:
+      - MYSQL_ROOT_PASSWORD=gitea
+      - MYSQL_USER=gitea
+      - MYSQL_PASSWORD=gitea
+      - MYSQL_DATABASE=gitea
+    networks:
+      - gitea
+    volumes:
+      - ./mysql:/var/lib/mysql

PostgreSQL database

To start Gitea in combination with a PostgreSQL database, apply these changes to the docker-compose.yml file created above.

version: "2"

networks:
  gitea:
    external: false

services:
  server:
    image: gitea/gitea:latest
    environment:
      - USER_UID=1000
      - USER_GID=1000
    restart: always
    networks:
      - gitea
    volumes:
      - ./gitea:/data
    ports:
      - "3000:3000"
      - "222:22"
+    depends_on:
+      - db
+
+  db:
+    image: postgres:9.6
+    restart: always
+    environment:
+      - POSTGRES_USER=gitea
+      - POSTGRES_PASSWORD=gitea
+      - POSTGRES_DB=gitea
+    networks:
+      - gitea
+    volumes:
+      - ./postgres:/var/lib/postgresql/data

Named volumes

To use named volumes instead of host volumes, define and use the named volume within the docker-compose.yml configuration. This change will automatically create the required volume. You don't need to worry about permissions with named volumes, Docker will deal with that automatically.

version: "2"

networks:
  gitea:
    external: false

+volumes:
+  gitea:
+    driver: local
+
services:
  server:
    image: gitea/gitea:latest
    restart: always
    networks:
      - gitea
    volumes:
-      - ./gitea:/data
+      - gitea:/data
    ports:
      - "3000:3000"
      - "222:22"

MySQL or PostgreSQL containers will need to be created separately.

Start

To start this setup based on docker-compose, execute docker-compose up -d, to launch Gitea in the background. Using docker-compose ps will show if Gitea started properly. Logs can be viewed with docker-compose logs.

To shut down the setup, execute docker-compose down. This will stop and kill the containers. The volumes will still exist.

Notice: if using a non-3000 port on http, change app.ini to match LOCAL_ROOT_URL = http://localhost:3000/.

Install

After starting the Docker setup via docker-compose Gitea should be available using a favorite browser to finalize the installation. Visit http://server-ip:3000 and follow the installation wizard. If the database was started with the docker-compose setup as documented above please note that db must be used as the database hostname.

Customization

Customization files described here should be placed in /data/gitea directory. If using host volumes it's quite easy to access these files; for named volumes this is done through another container or by direct access at /var/lib/docker/volumes/gitea_gitea/_data. The configuration file will be saved at /data/gitea/conf/app.ini after the installation.
