Unable to run with user other than UID 1000

[k3a]

Describe the bug
Helm makes it possible to define security context like this:

  elasticsearch:
    securityContextCustom:
      fsGroup: 1000
      runAsUser: 1000
      runAsGroup: 1000

Since #34 this works and it is possible to run the container as UID 1000.
Problem is, 1000 is the only possible UID as setting any other unprivileged UID results in permission denied to supervisord log file:

Traceback (most recent call last):

To Reproduce
Steps to reproduce the behavior:

1. Run as UID 1212
2. See error
3. Container terminated

Expected behavior
Container should run fine, as long as data directories are writable by the selected UID.
Logs should be output to stdout/stderr or data directories as /usr/share/ commonly contains mostly "static" files.

Configuration (please complete the following information):

• ODFE/Kibana version: 1.13.2
• Distribution: Helm
• Host Machine: Ubuntu 20.04.1 LTS

same here. it seems the image doesn't work fine with Openshift, where UID are random...
