Using GKE to deploy logstash by statefulset kind with pvc. Also need to install an output plugin.

When don't use `while true; do sleep 1000; done;` in container's command `args`, it can't deploy with pvc successfully.

The pod will cause `CrashLoopBackOff` error.

```auto
  Normal Created 13s (x2 over 14s) kubelet Created container logstash
  Normal Started 13s (x2 over 13s) kubelet Started container logstash
  Warning BackOff 11s (x2 over 12s) kubelet Back-off restarting failed container

```

From [here](https://stackoverflow.com/a/40093356/14718202) I found it can try to add sleep. So the statefulset with pvc can deploy successfully.

But when check its logs will find:

```auto
/bin/sh: bin/logstash-plugin: No such file or directory
/bin/sh: bin/logstash: No such file or directory

```

How to do it in a good way to start container to install an logstash output plugin?

The whole manifest file:

```auto
