关于/var/run/docker.sock

• http方式创建和启动容器，帮助理解

创建容器

curl -XPOST --unix-socket /var/run/docker.sock  -d '{"Image":"redis"}' -H 'Content-Type:application/json' http://localhost/containers/create

启动容器

curl -XPOST --unix-socket /var/run/docker.sock http://localhost/containers/773590db01d5061c9edb91ab258a2bfb537d00b76b74c695ff9cb7564b46d1c3/start

docker搭建jenkins

• docker-compose.yml
• 需要注意的是因为需求权限，所以添加root

version: '3.1'
services:
  jenkins:
    restart: always
    image: jenkinsci/jenkins
    container_name: jenkins
    ports:
      - 8080:8080
    volumes:
      - /usr/local/docker/jenkins/jenkinsci_home:/var/jenkins_home
      - /var/run/docker.sock:/var/run/docker.sock
    user: root
