普通单container的pod

kubectl cp 命名空间/容器名:/容器目录/文件名 /宿主机目录/文件名

多container的pod

kubectl cp  容器名:/容器目录/文件名  -c 指定的container名 /宿主机目录/文件名 -n 命名空间
    # 从namespace为test pod名称为servicecenter-dp-0,其中container名称为servicecenter中cp jar包
    kubectl cp  servicecenter-dp-0:/srv/servicecenter/ihaozhuo-servicecenter-6.0.1-SNAPSHOT.jar  -c servicecenter /tmp/ihaozhuo-servicecenter-6.0.1-SNAPSHOT.jar -n test

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
      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]
