2.11容器间文件的拷贝

[root@host152 myfile]# docker cp --help

Usage: docker cp [OPTIONS] CONTAINER:SRC_PATH DEST_PATH|-
docker cp [OPTIONS] SRC_PATH|- CONTAINER:DEST_PATH

Copy files/folders between a container and the local filesystem

Use '-' as the source to read a tar archive from stdin
and extract it to a directory destination in a container.
Use '-' as the destination to stream a tar archive of a
container source to stdout.

Options:
-a, --archive Archive mode (copy all uid/gid information)
-L, --follow-link Always follow symbol link in SRC_PATH

2.11.1启动centos

[root@host152 ~]# docker run -itd --name centos-docker centos /bin/bash

登陆创建的centos容器

[root@host152 ~]# docker exec -it centos-docker /bin/bash

2.11.2复制宿主机文件到运行的docker容器

[root@host152 myfile]# docker cp a.txt centos-docker:/root/dockerfile

登陆容器查看文件是否复制成功
[root@host152 myfile]# docker exec -it centos-docker /bin/bash
[root@0966db9df33d /]# cd /root/dockerfile
[root@0966db9df33d dockerfile]# ll
total 4
-rw-r--r-- 1 root root 24 Aug 1 10:24 a.txt

2.11.3把docker文件复制出来到宿主查

[root@host152 myfile]# docker cp centos-docker:/root/dockerfile/dockerfile.txt /root/myfile/
[root@host152 myfile]# ll
total 8
-rw-r--r-- 1 root root 24 Aug 1 18:24 a.txt
-rw-r--r-- 1 root root 22 Aug 1 18:40 dockerfile.txt

1.12启动挂载目录文件

我们可以在创建容器的时候，将宿主机的目录与容器内的目录进行映射，这样我们就可以通过修改宿主机某个目录的文件从而去影响容器。
创建容器添加-v参数后边为宿主机目录:容器目录

[root@host152 myfile]# docker run -id --name=centos-load -v /root/myfileload:/root/dockerfile centos

如果有权限问题，是因为CentOS7中的安全模块selinux把权限禁掉了，我们需要添加参数 -- privileged=true 来解决挂载的目录没有权限的问题

[root@host152 myfile]# docker run -id --privileged=true --name=centos-load -v /root/myfileload:/root/dockerfile centos
