klog.sh fails with kubecf/cap 2.0

[greygoo]

Describe the bug
When running klog.sh with a kubecf deployment, it fails on copying log files from the log container in the adapter-0 pod with command terminated with exit code 126

To Reproduce
this is how klog.sh behaves:

> ./bin/klog.sh 
Pod acceptance-tests-530a82ca6917486c-w6ksb = Failed
  - acceptance-tests-acceptance-tests logs: Kube
  - output-persist logs: Kube
  Descriptions ...
Pod adapter-0 = Running
  - adapter-adapter logs: CF Kube
  - loggregator-agent-loggregator-agent logs: CF Kube
  - loggr-forwarder-agent-loggr-forwarder-agent logs: CF Kube
  - logs logs: CF

> echo $?
126

running it with bash -x reveals that this is the failing command:

> kubectl cp --namespace scf --container logs adapter-0:/var/vcap/sys/log/ /home/chullerlocal/klog/scf/adapter-0/logs/
command terminated with exit code 126

Expected behavior
klog.sh should collect and package the log files..

Environment

• cap2.0 RC2
• klog.sh
• deployment was on aks

Additional context
I checked for differences between the pod klog.sh fails upon and ones where it works:

• in the log container of the adapter-0 pod (the one klog.sh fails):

  • no tar command was available
  • permissions in the log dir:

        adapter-0:/ # ls -lh /var/vcap/sys/log/
        total 12K
        drwxr-sr-x 2 vcap vcap 4.0K May 27 15:04 adapter
        drwxr-sr-x 2 vcap vcap 4.0K May 27 15:04 loggr-forwarder-agent
        drwxr-sr-x 2 vcap vcap 4.0K May 27 15:04 loggregator_agent
    

• in the loggr-forwarder-agent-loggr-forwarder-agent container in the adapter-0 pod (works with klog.sh):

  • tar command available
  • permissions in the log dir:

        /:/var/vcap/jobs/adapter# ls -lh /var/vcap/sys/log/
        total 12K
        drwxr-sr-x 2 vcap adm 4.0K May 27 15:04 adapter
        drwxr-sr-x 2 vcap adm 4.0K May 27 15:04 loggr-forwarder-agent
        drwxr-sr-x 2 vcap adm 4.0K May 27 15:04 loggregator_agent

If you are using kubecf, please be sure to use the kubecf version of klog.sh.
