使用docker最小化部署Git CI环境

写就时间戳 2021-05-27

本文使用环境:

Debian GNU/Linux 10 (buster) / 内核版本号 Debian 4.19.146 
### Ubuntu18+应该也是完全通用,但并没有测试
docker 20.10.6
docker-compose 1.24.1
caddy v2.4.1
gitea 1.14.2
drone v1

各组件作用简介

模块 作用
docker 如果你需要看这个,我觉得你适合继续看此文
docker-compose docker的包装工具,自动启动多个 docker container
caddy 为 gitea 对外提供一个webserver,自动申请https证书等
gitea git 服务器
drone CI 服务 包含 drone server, drone runner

OS

初始化Debian

使用云服务商自动创建并选择os最简单,建议使用阿里云、腾讯云。

更改sshd默认端口号

如果不改这个端口号,就需要调整gitea端口,那样的话,默认的clone地址中就会有自定义端口号,对某些兼容性不够的工具造成困扰。

/etc/ssh/sshd_config

Port 2222

改好sshd配置,重启一下ssh

systemctl restart ssh

Install docker

如果你过去安装过 docker,先删掉:

apt-get remove docker docker-engine docker.io
apt-get install apt-transport-https ca-certificates curl gnupg2 software-properties-common
curl -fsSL https://download.docker.com/linux/debian/gpg | apt-key add -

下面的镜像地址,选1个就好

# 使用阿里云镜像地址
add-apt-repository \
   "deb [arch=amd64] http://mirrors.aliyun.com/docker-ce/linux/debian \
   $(lsb_release -cs) \
   stable"
   
# 使用清华镜像地址
add-apt-repository \
   "deb [arch=amd64] https://mirrors.tuna.tsinghua.edu.cn/docker-ce/linux/debian \
   $(lsb_release -cs) \
   stable"
   
apt-get update
apt-get install docker-ce

配置docker

cat <<EOF > /etc/docker/daemon.json
{
  "registry-mirrors": ["https://xxxxxx.mirror.aliyuncs.com"], # 指定一个docker拉取加速地址
   "exec-opts": ["native.cgroupdriver=systemd"],
   "log-driver": "json-file",
   "log-opts": {
     "max-size": "100m"
   },
   "data-root":"/data/dockerd", # 更换使用自定义docker数据目录
   "storage-driver": "overlay2"
}
EOF

systemctl stop ufw
update-rc.d ufw disable

systemctl  reload docker
systemctl  restart docker

安装 docker-compose

curl -L https://github.com/docker/compose/releases/download/1.24.1/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose

启动gitea后,需要先创建 oauth 应用

drone server自身没有提供登录系统,而是通过 gitea 的 oauth 应用接入来完成鉴权。

启动 drone server 前必须指定。

配置 drone-server drone-runner

docker-compose

version: "2"

networks:
  gitea:
    external: false

services:
  gitea:
    # image: gitea/gitea:1.14.2
    image: gitea/gitea:1.13.7
    environment:

      - USER_GID=1000
    restart: always
    networks:
      - gitea
    volumes:

      - /etc/localtime:/etc/localtime:ro
    ports:
      - "3000:3000"
      - "22:22"

  drone-server:
    image: drone/drone:1
    ports:
      - "8080:80"
    volumes:
      - /data/drone-server:/data

      - DRONE_RPC_SECRET=da0121bb74c18666c32515e8b93cd5c5   # 和下面部分一致
      - DRONE_SERVER_HOST=gitea-drone.somewhere.com
      - DRONE_SERVER_PROTO=https
      - DRONE_TLS_AUTOCERT=false

  drone-runner:
    image: drone/drone-runner-docker:1
    #ports:
      #- "8080:80"
    volumes:
      - /data/drone-runner:/data

      - DRONE_RUNNER_CAPACITY=2
      - DRONE_RUNNER_NAME=runner-01
  

Caddyfile

gitea.somewhere.com {
    reverse_proxy localhost:3000 {
        # transparent
    }
}

gitea-drone.somewhere.com {
    reverse_proxy localhost:8080 {
        # transparent
    }
}

demo 项目

在项目中添加如下文件:

.drone.yml

kind: pipeline
type: docker
name: build

# volumes:
# - name: dockersock
#   host:
#     path: /var/run/docker.sock

trigger:
  branch:
  - master
  - testing

steps:
- name: image
  image: alpine:3.11
  # volumes:
  # - name: dockersock
  #   path: /var/run/docker.sock
  environment:
    docker_user:
      from_secret: docker_user
    docker_password:
      from_secret: docker_password
    docker_host:
      from_secret: docker_host
  commands:
  # - echo $docker_user
  # - echo "docker pswd=$docker_password"
  # - docker build -t ${DRONE_REPO_NAME}:${CI_COMMIT_BRANCH} .
  # - docker rm -f "${DRONE_REPO_NAME}" || true
  # - docker run -itd --name ${DRONE_REPO_NAME} -v /data/${DRONE_REPO_NAME}/config.yaml:/config.yaml --restart always -p9090:80 ${DRONE_REPO_NAME}:${CI_COMMIT_BRANCH}
  - echo "OK" && date && echo "done"
