Say I have, my-namespace -> my-pod -> my-container
and I have a file located at my-container:/opt/tomcat/logs/catalina.2017-05-02.log. I have applied the below command to copy the file which isn't working,

```
kubectl cp my-namepace/my-pod:/opt/tomcat/logs/catalina.2017-05-02.log -c my-container .

```

Note: I have the tar binary on my container

Error:

```
tar: Removing leading `/' from member names
error: open .: is a directory

```
