CICD With DroneCI and Gitea Using Docker Compose

In this post we wil set up a drone-ci and gitea stack using docker-compose and then running a test pipeline.

I have posted a few times about this topic, but this post will be used when I create other examples and wanting to use this post for the ones not having the stack booted yet.

The Source Code

All the code will be in my github repository.

For our docker-compose.yml:

version: '3.6'

services:
  gitea:
    container_name: gitea
    image: gitea/gitea:${GITEA_VERSION:-1.10.6}
    restart: unless-stopped
    environment:
      # https://docs.gitea.io/en-us/install-with-docker/#environments-variables
      - APP_NAME="Gitea"
      - USER_UID=1000
      - USER_GID=1000
      - RUN_MODE=prod
      - DOMAIN=${IP_ADDRESS}
      - SSH_DOMAIN=${IP_ADDRESS}
      - HTTP_PORT=3000
      - ROOT_URL=http://${IP_ADDRESS}:3000
      - SSH_PORT=222
      - SSH_LISTEN_PORT=22
      - DB_TYPE=sqlite3
    ports:
      - "3000:3000"
      - "222:22"
    networks:
      - cicd_net
    volumes:
      - ./gitea:/data

  drone:
    container_name: drone
    image: drone/drone:${DRONE_VERSION:-1.6.4}
    restart: unless-stopped
    depends_on:
      - gitea
    environment:
      # https://docs.drone.io/server/provider/gitea/
      - DRONE_DATABASE_DRIVER=sqlite3
      - DRONE_DATABASE_DATASOURCE=/data/database.sqlite
      - DRONE_GITEA_SERVER=http://${IP_ADDRESS}:3000/
      - DRONE_GIT_ALWAYS_AUTH=false
      - DRONE_RPC_SECRET=${DRONE_RPC_SECRET}
      - DRONE_SERVER_PROTO=http
      - DRONE_SERVER_HOST=${IP_ADDRESS}:3001
      - DRONE_TLS_AUTOCERT=false
      - DRONE_USER_CREATE=${DRONE_USER_CREATE}
      - DRONE_GITEA_CLIENT_ID=${DRONE_GITEA_CLIENT_ID}
      - DRONE_GITEA_CLIENT_SECRET=${DRONE_GITEA_CLIENT_SECRET}
    ports:
      - "3001:80"
      - "9001:9000"
    networks:
      - cicd_net
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
      - ./drone:/data

  drone-runner:
    container_name: drone-runner
    image: drone/drone-runner-docker:${DRONE_RUNNER_VERSION:-1}
    restart: unless-stopped
    depends_on:
      - drone
    environment:
      # https://docs.drone.io/runner/docker/installation/linux/
      # https://docs.drone.io/server/metrics/
      - DRONE_RPC_PROTO=http
      - DRONE_RPC_HOST=drone
      - DRONE_RPC_SECRET=${DRONE_RPC_SECRET}
      - DRONE_RUNNER_NAME="${HOSTNAME}-runner"
      - DRONE_RUNNER_CAPACITY=2
      - DRONE_RUNNER_NETWORKS=cicd_net
      - DRONE_DEBUG=false
      - DRONE_TRACE=false
    ports:
      - "3002:3000"
    networks:
      - cicd_net
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock

networks:
  cicd_net:
    name: cicd_net

Our boot.sh which we will use to override environment variables:

#!/usr/bin/env bash

export HOSTNAME=$(hostname)
export DRONE_VERSION=1.10.1
export DRONE_RUNNER_VERSION=1.6.3
export GITEA_VERSION=1.13
export IP_ADDRESS=192.168.0.6
export MINIO_ACCESS_KEY="EXAMPLEKEY"
export MINIO_SECRET_KEY="EXAMPLESECRET"
export GITEA_ADMIN_USER="example"
export DRONE_RPC_SECRET="$(echo ${HOSTNAME} | openssl dgst -md5 -hex)"
export DRONE_USER_CREATE="username:${GITEA_ADMIN_USER},machine:false,admin:true,token:${DRONE_RPC_SECRET}"
export DRONE_GITEA_CLIENT_ID=""
export DRONE_GITEA_CLIENT_SECRET=""
docker-compose up -d

echo ""
echo "Gitea: http://${IP_ADDRESS}:3000/"
echo "Drone: http://${IP_ADDRESS}:3001/"

Deploy the Stack

Set the following in your boot.sh:

IP_ADDRESS=192.168.0.6       -> either reachable dns or ip address which will be your clone address and ui addresses.
GITEA_ADMIN_USER="giteauser" -> will be the user you register with in drone

Now boot the stack:

$ bash boot.sh

Note: Theres a current issue where webhooks get fired twice, if you see that just restart gitea with docker restart gitea.

Head over to: http://${IP_ADDRESS}:3000/user/settings/applications and create a new OAuth2 Application and set the Redirect URI to http://${IP_ADDRESS}:3001/login
Capture the client id and client secret and populate them in the boot.sh in DRONE_GITEA_CLIENT_ID and DRONE_GITEA_CLIENT_SECRET and run bash boot.sh again. This will give drone the correct credentials in order to authenticate with gitea.
Now when you head over to http://${IP_ADDRESS}:3001/ you will be asked to authorize the application and you should be able to access drone.

Drone CLI

Install Drone CLI: - https://docs.drone.io/cli/install/

$ curl -L https://github.com/drone/drone-cli/releases/latest/download/drone_darwin_amd64.tar.gz | tar zx
$ sudo mv drone /usr/local/bin/drone
$ chmod +x /usr/local/bin/drone

Get your Drone Token: - http://${IP_ADDRESS}:3001/account

$ export DRONE_SERVER=http://${IP_ADDRESS}:3001
$ export DRONE_TOKEN=one-from-the-account-page
drone info

Build your first pipeline

Create a test repo in gitea:

Commit a .drone.yml file for drone:

kind: pipeline
type: docker
name: hello-world

trigger:
  branch:
    - master
  event:
    - push

steps:
  - name: say-hello
    image: busybox
    commands:
      - echo hello-world
