      Upstream description:

      I'm trying to use podman-compose to develop a compose file for an application, and I'm having issues when I try to start single containers after podman-compose up failed. I'm having an issue like that:

      $ sudo podman-compose start web
      using podman version: podman version 1.8.2
      podman start myapp_web_1
      Error: unable to start container "myapp_web_1": cannot listen on the TCP port: listen tcp4 :3000: bind: address already in use
      125

      And when I look, port 3000 is held by conmon that keeps running for the previous version of the same container that exited long ago.

      I believe conmon should not keep opened ports for stopped containers.

      Version information (all running on Fedora 32 silverblue):

      • podman-compose-0.1.7.dev0
      • podman-1.8.2-2.fc32.x86_64
      • conmon-2.0.14-1.fc32.x86_64
