Describe the bug

A clear and concise description of what the bug is.

Steps to reproduce

1. start collabora container
   2.check docker logs

Expected behavior

quiet log

Actual behavior

collabora container reports
ERR opencloud-eu/opencloud#17: Read failed, have 1 buffered bytes (ECONNRESET: Connection reset by peer)

Setup

Please describe how you started the server and provide a list of relevant environment variables or configuration files.

locally running OC out of https://github.com/opencloud-eu/opencloud-compose.git
version : git pull from today, bfc2a64

setting a different delay for the healtcheck of collabora makes also the messages appear on the same frequency -> correlation

one solution, instead of the cryptic command, would be to use curl (is included in the container), replacing

    healthcheck:
      test: ["CMD", "bash", "-c", "exec 3<>/dev/tcp/127.0.0.1/9980 && echo -e 'GET /hosting/discovery HTTP/1.1\r\nHost: localhost:9980\r\n\r\n' >&3 && head -n 1 <&3 | grep '200 OK'"]

with

    healthcheck:
      test: ["CMD", "bash", "-c", "curl -f localhost:9980/hosting/discovery"]

I like your proposed fix. We will set this to p3. If you have time open a PR.
Also moving this to the compose repo.

Is curl available in that container?

Back in the days where this has been created, there was no curl inside the collabora container.

Seems to already be handled by #209

Actually, the healthcheck was changed to use curl in fe3497e.
