You’re troubleshooting file permissions. Remove your init container and try out the following. If you could provide this output it might also be useful in helping you.

Get a shell into the container.

```nohighlight
kubectl exec -it POD_NAME -- sh

```

Confirm your uid and gid.

```nohighlight
/ $ id
uid=1001 gid=1001 groups=1001

```

Test writing to the directory.

```nohighlight
/ $ echo test > /opt/var/logs/docker/test.txt 
/ $ cat /opt/var/logs/docker/test.txt
test

```

Walk the directory and confirm permissions along the directory.

```nohighlight
/ $ ls -lah /opt /opt/var /opt/var/logs /opt/var/logs/docker/
/opt:
total 12K    
drwxr-xr-x 1 root root 4.0K Jun 30 14:06 .
