修改docker+jenkins挂载目录

1.停止docker

[[email protected] data]# systemctl stop docker

2.创建目录,拷贝数据

[[email protected] data]# mkdir -p /newdata/jenkins
//要保证目录的属主和属组不变,设置新目录权限777是为了cp -a能正常拷贝属主和属组等全部信息
[[email protected] data]# chmod 777 /newdata/jenkins
[[email protected] data]# cp -a /data/jenkins /newdata/jenkins
[[email protected] data]# ll /newdata/
total 36
drwxr-xr-x 4 root root 4096 Feb 11 11:02 elasticsearch
drwxrwxrwx 22 root root 4096 May 18 12:57 jenkins
drwx------ 2 root root 16384 Mar 22 17:08 lost+found
drwxr-xr-x 10 root root 4096 Mar 26 2018 zbox
[[email protected] data]#

 

3.容器的配置文件路径:

修改 /var/lib/docker/containers/[hash_of_the_container]/config.v2.json
   /var/lib/docker/containers/[hash_of_the_container]/hostconfig.json

其中的hashofthecontainer是docker镜像的hash值,可以通过docker ps或者docker inspect containername查看。(CONTAINER ID就可以看出来)
