Docker 部署 jenkins 并正确迁移到新服务器

镜像迁移

• 旧服务器导出镜像

# 根据容器创建新镜像
docker commit jenkins my/jenkins:1.0.0
# 导出镜像
docker save -o my-jenkins.tar my/jenkins:1.0.0

• 新服务器导入镜像

# 新环境中导入镜像
docker load -i my-jenkins.tar
# 新环境中 jenkins_home 目录添加权限
sudo chown -R 1000:1000 /u01/jenkins_home

• docker-compose.yml

version: '3'
services:
  jenkins:
    image: my/jenkins:1.0.0
    container_name: jenkins
    restart: always
    network_mode: "host"
    privileged: true
    volumes:
      - /etc/localtime:/etc/localtime
      - /u01/jenkins_home:/var/jenkins_home
    environment:
      JAVA_OPTS: "-Duser.timezone=Asia/Shanghai"
      JENKINS_OPTS: "--prefix=/jenkins --httpPort=8000"
      JENKINS_ARGS: "--prefix=/jenkins"

• 部署 jenkins

docker-compose up -d jenkins
