This is a repo for testing Drone CI (on NixOS)

On this repo i was working to setup succesfully the continous integration on my home server. Small tutorial above...

Tutorial for Traefik + NixOS environment

1. Github configuration. Follow the OAuth configuration on this tutorial

2. Traefik things. Fill a docker-compose file.For example, like this:

version: '3.7'

services:
  drone-server:
    container_name: drone-server
    image: drone/drone
    restart: unless-stopped
    ports:
      - 8080:80
    volumes:
      - /var/lib/drone:/data
      - /var/run/docker.sock:/var/run/docker.sock
    environment:
      - DRONE_GITHUB_SERVER=https://github.com
      - DRONE_GITHUB_CLIENT_ID=<GITHUB_ID>
      - DRONE_GITHUB_CLIENT_SECRET=<GITHUB_SECRET>
      - DRONE_AGENTS_ENABLED=true
      - DRONE_RPC_SECRET=<Your RPC_SECRET>
      - DRONE_SERVER_HOST=<Your URL>
      - DRONE_SERVER_PROTO=https
      - DRONE_TLS_AUTOCERT=true
      - DRONE_USER_CREATE=username:<Username GITHUB>,admin:true
      - DRONE_LOGS_TRACE=true
      - DRONE_LOGS_PRETTY=true
      - DRONE_LOGS_COLOR=true
    labels:
      - traefik.enable=true
      - traefik.http.services.drone.loadbalancer.server.port=80
      - traefik.http.routers.drone.entryPoints=web-secure
      - traefik.http.routers.drone.rule=Host(`<Your URL>`)
      - traefik.http.routers.drone.tls.certresolver=default

Start the container: docker-compose up -d

3. Setting up the executor. In this case, I need a host runner executor. Actually I'm using NixOS, so:
   1. Download the drone-exec binary (its on official website) curl -L https://github.com/drone-runners/drone-runner-exec/releases/latest/download/drone_runner_exec_linux_amd64.tar.gz | tar zx
   2. Move to /root/bin/
   3. Add to configuration.nix:

environment.etc.drone-runner-exec = {
    target = "drone-runner-exec/config";
    text = ''
    DRONE_RPC_PROTO=https
    DRONE_RPC_HOST=<Your host URL>
    DRONE_RPC_SECRET=<Your RPC_SECRET>
    DRONE_UI_USERNAME=root
    DRONE_UI_PASSWORD=root
    '';
  };

  systemd.services.drone-runner-exec = {
    description = "Drone Exec Runner";
    startLimitIntervalSec = 5;
    serviceConfig = {
      ExecStart = "/root/bin/drone-runner-exec service run --config /etc/drone-runner-exec/config";
    };
    wantedBy = [ "multi-user.target" ];
    path = [ pkgs.git pkgs.docker pkgs.docker-compose ];
  };

4. Go to ur Drone URL and auth with ur GitHub account.
5. Enable a repo to be CI and add a .drone.yml like this:

kind: pipeline
type: exec
name: default

platform:
  os: linux
  arch: amd64

steps:
- name: build
  commands:
    - docker build -t drone-tests .

- name: run
  commands:
    - cd /var/docker/project
    - docker-compose stop drone-tests
    - docker-compose up -d drone-tests

6. You can check the deploy status on Drone webpage.
