Raspberry Pi 5: Part-1: Install Docker and Gitea	2025-05-05	raspi-5-docker-p1	Setting up docker to containerize UI app and back-end with CI/CD

Getting started

Welcome to the series where I will be setting up a mini server to host your own website. We will do a self hosted git server. Then we will install woodpecker, a lightweight CI/CD system to trigger pipelines in push to git repo. And then we will setup Grafana to monitor the traffic to Raspberry Pi 5. We will then add TLS with Caddy and also add some reverse proxy and also do port forwarding for more security.

Installing Docker

sudo apt update && sudo apt upgrade -y

curl -sSL https:..get.docker.com | sh
sudo usermod -aG docker $USER

Installing Gitea

mkdir -p ~/gitea
cd ~/gitea

Create the docker-compose.yaml:

version: '3'

services:
  gitea:
    image: gitea/gitea:latest
    container_name: gitea
    environment:
      - USER_UID=1000
      - USER_GID=1000
    restart: always
    volumes:
      - ./gitea:/data
    ports:
      - '3000:3000'
      - '2222:22'

Launch Gitea:

docker compose up -d

Create admin user:

docker exec -it gitea /bin/bash

gitea admin use  create \
  --username youradmin \
  --password yourpassword \
  --email you@example.com \
  --admin \
  --must-change-password=false

Exit the container

exit
