I'm having issues running my system within a docker container. By experimenting, I've managed to observe that

• it seems like my publishers don't publish. Noting shows up ros2 topic hz/echo in the container, same outside of it. Weird thing is that most of the time ros2 topic info will show the right number of publishers, sometimes it will show 0
• Some service works, others don't. While I can call some services using rqtservicecaller and get the correct response, when I can others, the node providing the service will print out the correct request but rqtservicecaller will freeze as it never get the response.
• The problem may be limited to my package, I've tried running examplesrclpyminimalpublisher publisherlocalfunction it works without any issues (except that it seems a bit low view from outside the container on rqttopic)
• If I run ros2 topic echo topic before the publisher is launched it will work, but if I restart the echo, it will no longer connect

So additional information:

• Publisher in my package all uses qos.qosprofilesystem_default
• Nodes run using USESIMTIME=True (I've tried without it but no change)
• Launching nodes using a launch file
• Nodes are written python

Run my docker using

docker run --rm -it

and below is the dockerfile if created
