Docker Config option for Splunk web.conf error

[jjesudass]

I am using Splunk/splunk:latest version(7.0.0) and docker compose version (3.4) .
Also deploying an nginx proxy with context root as /splunk to forward to splunk web at 8000.

The web.conf is added to the container as a docker config at /opt/splunk/etc/system/local/web.conf as root user, and also starting the container as root user.
The splunk container fails to start with error: chown: changing ownership of ‘/opt/splunk/etc/system/local/web.conf’: Read-only file system

web.conf:

[settings]

root_endpoint=/splunk

I am running the latest docker image and have a similar issue. Running 7.0.2 on Docker CE with Portainer.
The user and group defined by the default variables are splunk splunk
However when I check the files in the /etc volume they are all owned by docker with the exception of modified files which become owned by root.

The container stops with error 13 access denied web.conf

Running the container with environment variables set to root, allows the container to start.

Something is a miss with the ownership when this container makes changes to the file system. For now I'm just running it as root:root
