在jenkins容器内部使用docker

在jenkins容器内部使用docker

1.使用本地的docker

进入/var/run,找到docker.sock

[root@npy run]# ls
auditd.pid  containerd   cryptsetup          dmeventd-client  docker.pid   initramfs  lvm          netreport       sepermit  sudo         tmpfiles.d  user
chrony      crond.pid    dbus                dmeventd-server  docker.sock  lock       lvmetad.pid  NetworkManager  setrans   syslogd.pid  tuned       utmp
console     cron.reboot  dhclient-ens33.pid  docker           faillock     log        mount        plymouth        sshd.pid  systemd      udev        xtables.lock
[root@npy run]# pwd
/var/run
[root@npy run]# 

2.修改docker.sock文件所属组

chown root:root docker.sock

3.修改权限

chmod o+rw docker.sock

此时的docker.sock

srw-rw-rw-  1 root   root      0 2月  11 20:39 docker.sock

4. 修改jenkins的docker-compose.yml

追加挂载数据

/var/run/docker.sock://var/run/docker.sock

/usr/bin/docker:/usr/bin/docker

/etc/docker/daemon.json:/etc/docker/daemon.json

version: '3.1'
services:
  jenkins:
    image: jenkins/jenkins
    privileged: true
    user: root
    ports:
      - 10240:8080
      - 10241:50000
    container_name: npy_jenkins
    volumes:
      - /home/jenkins/jenkins_mount:/var/jenkins_home
      - /etc/localtime:/etc/localtime
      - /var/run/docker.sock://var/run/docker.sock
      - /usr/bin/docker:/usr/bin/docker
      - /etc/docker/daemon.json:/etc/docker/daemon.json

5.docker测试

进入容器执行docker,发现版本可以显示

[root@npy jenkins_docker]# docker exec -it 65f2c8960631 bash
