1、创建容器备份

docker ps
docker commit -p jenkins jenkins_backup

2、将备份容器导出为文件

docker image
docker save -o jenkins_backup.tar jenkins_backup

3、数据目录备份

tar -czvf jenkins.tar.gz jenkins/

4、文件复制至远程服务器

scp jenkins.tar  root@192.168.1.30:/data/
scp jenkins_backup.tar  root@192.168.1.30:/data/

5、文件复制至远程服务器

scp jenkins.tar  root@192.168.1.30:/data/
scp jenkins_backup.tar  root@192.168.1.30:/data/

6、文件解压与容器导入

tar -xzvf jenkins.tar.gz
docker load -i jenkins_backup.tar

7、容器运行

docker run --name jenkins -p 8080:8080 -p 50000:50000 \
  -v /etc/localtime:/etc/localtime:ro \
  -v /run/docker.sock:/var/run/docker.sock \
  -v $(which docker-compose):/usr/bin/docker-compose \
  -v $(which docker):/usr/bin/docker \
  -v /data/jenkins:/var/jenkins_home \
  -e TZ=Asia/Shanghai \
  --restart=always \
  -u 0 -d jenkins_backup
