Build Gitea on Docker

Deploying Gitea on Docker involves setting up the Gitea application along with a database backend. Here’s a step-by-step guide to deploy Gitea using Docker Compose:

Step 1: Prepare Docker Compose File

Create a docker-compose.yml file to define the services (Gitea and MySQL in this case):

version: '3'

services:
  server:
    image: gitea/gitea:latest
    environment:
      - USER_UID=1000  # Replace with your host user UID if necessary
      - USER_GID=1000  # Replace with your host group GID if necessary
    restart: always
    volumes:
      - ./gitea:/data
    ports:
      - "3000:3000"
      - "2222:22"  # SSH port (optional, adjust as needed)
    depends_on:
      - db
    networks:
      - gitea_network

  db:
    image: mysql:5.7
    environment:
      MYSQL_DATABASE: gitea
      MYSQL_USER: gitea
      MYSQL_PASSWORD: password
      MYSQL_ROOT_PASSWORD: root_password
    volumes:
      - ./mysql:/var/lib/mysql
    restart: always
    networks:
      - gitea_network

networks:
  gitea_network:
    driver: bridge

Step 2: Configure Docker Compose File

  • Gitea (server service):

    • image: Pulls the latest Gitea Docker image.
    • environment: Sets user UID and GID for file permissions (adjust if necessary).
    • volumes: Mounts a local directory ./gitea to persist Gitea data.
    • ports: Maps container ports 3000 (HTTP) and 2222 (SSH) to host ports (adjust as needed).
    • depends_on: Ensures the db service starts before Gitea.
    • networks: Connects to a custom bridge network gitea_network.

  • MySQL (db service):

    • image: Pulls the MySQL 5.7 Docker image.
    • environment: Sets MySQL database name, user, and passwords.
    • volumes: Mounts a local directory ./mysql to persist MySQL data.
    • restart: Always restarts the MySQL container if it stops unexpectedly.
    • networks: Connects to the gitea_network for communication with Gitea.

Step 3: Deploy Gitea

Run the following command in the directory containing your docker-compose.yml file:

docker-compose up -d

This command starts both Gitea and MySQL containers in detached mode (-d), allowing them to run in the background.

Step 4: Access Gitea

After deployment, access Gitea through your browser at http://localhost:3000. Replace localhost with your server's IP address or domain name if accessing remotely.

Step 5: Initial Setup

Follow the on-screen instructions to complete the initial setup of Gitea, including setting up an admin account and configuring basic settings.

Notes:

  • Data Persistence: Data for Gitea and MySQL will persist in local directories ./gitea and ./mysql. Adjust paths and volumes as needed.

  • Customization: Customize environment variables and ports according to your specific requirements.

  • Security: Consider securing Gitea with HTTPS using Nginx or another reverse proxy and obtaining SSL/TLS certificates.

This setup provides a basic deployment of Gitea using Docker Compose. Modify as per your environment and security requirements for production use.
