Hi.
Looks like there was a similar question in the forum
https://discourse.haproxy.org/t/trouble-with-starting-the-data-plane-api/9200
Any idea how to fix this?
Regards
Alex

Hi.
I try to run dataplane as "random" user inside haproxy.cfg.
That's the debug output of the start of the container. Even as I have set the
--log-level=trace to the dataplane can't I see any reason why the api kills the
process.

```
When I start HAProxy without the lines in the Block "program api" HAProxy is
able to start. After I connect with another shell to the container and run the
dataplane inside the container can I see that dataplane connects to haproxy and
stops immediately.

Is there any chance to get more information's from the dataplane why it it's
exitig?
Attached the Dockerfile and the haproxy.cfg which I use.
Thanks for any help.
Best regards
