第一步：配置deployment，指定PVC
第二步，执行kubectl cp命令，拷贝文件到容器指定的目录/data
文件夹拷贝到容器的根目录下
root@master:~/fpi/park-gis-web# kubectl cp ./data ipes-nanjing/park-gis-web-d5f74d88f-mqtj6:/
//文件夹，从本地拷贝到容器
kubectl cp ./data ipes-nanjing/park-gis-web-757df84795-8lrw6:/
//文件夹，从容器拷贝到本地
kubectl cp ipes-nanjing/gateway-server-69cf9485b5-p8kwt:/config/ ./
//从pod复制文件到宿主机，从容器拷贝到本地
【错误】kubectl cp ipes-nanjing/gateway-server-69cf9485b5-p8kwt:/config/application.yml ./application.yml
报错：root@master:~/fpi/tempyml# kubectl cp ipes-nanjing/gateway-server-69cf9485b5-p8kwt:/config/application.yml ./application.yml
tar: Removing leading `/' from member names
warning: file "application.yml" is a symlink, skipping (consider using "kubectl exec -n "ipes-nanjing" "gateway-server-69cf9485b5-p8kwt" -- tar cf - "/config/application.yml" | tar xf -")
//从pod复制文件到宿主机
第一步，在pod内部，把文件cp到exec默认进去的目录/app
root@gateway-server-69cf9485b5-p8kwt:/app# cp /config/application.yml ./
第二步，调用kubectl cp命令，目标参数时，必须为文件不能是一个目录(eg:application.yml)
kubectl cp ipes-nanjing/gateway-server-69cf9485b5-p8kwt:application.yml ./application.yml
[root@qd01-test-yinhe177004066 daicong_test]# kubectl cp --help
Copy files and directories to and from containers.
Examples:
# !!!Important Note!!!
# Requires that the 'tar' binary is present in your container
# image. If 'tar' is not present, 'kubectl cp' will fail.
#
# For advanced use cases, such as symlinks, wildcard expansion or
# file mode preservation consider using 'kubectl exec'.
# Copy /tmp/foo local file to /tmp/bar in a remote pod in namespace <some-namespace>
tar cf - /tmp/foo | kubectl exec -i -n <some-namespace> <some-pod> -- tar xf - -C /tmp/bar
# Copy /tmp/foo from a remote pod to /tmp/bar locally
kubectl exec -n <some-namespace> <some-pod> -- tar cf - /tmp/foo | tar xf - -C /tmp/bar
# Copy /tmp/foo_dir local directory to /tmp/bar_dir in a remote pod in the default namespace
kubectl cp /tmp/foo_dir <some-pod>:/tmp/bar_dir
# Copy /tmp/foo local file to /tmp/bar in a remote pod in a specific container,in the default namespace
kubectl cp /tmp/foo <some-pod>:/tmp/bar -c <specific-container>
# Copy /tmp/foo local file to /tmp/bar in a remote pod in namespace <some-namespace>
kubectl cp /tmp/foo <some-namespace>/<some-pod>:/tmp/bar
# Copy /tmp/foo from a remote pod to /tmp/bar locally
kubectl cp <some-namespace>/<some-pod>:/tmp/foo /tmp/bar
Options:
-c, --container='': Container name. If omitted, the first container in the pod will be chosen
--no-preserve=false: The copied file/directory's ownership and permissions will not be preserved in the container
Usage:
kubectl cp <file-spec-src> <file-spec-dest> [options]
Use "kubectl options" for a list of global command-line options (applies to all commands).

* 举例将本地的localtime文件复制到容器中实现时间的同步
```bash
kubectl cp /etc/localtime <dest-pod>:/etc/localtime -c <container-name> -n <namespace-name>
