    Description

      Hello Friends:

      After the successful launch of a Debezium docker container – actually I'm using rootless podman(1) – the Java ReST UNIX process is running, but port 8083 is not LISTENING.

      SIDEBAR: The podman run --publish 28083:8083 [ ... ] command is so published to avoid conflict on the bare-metal HOST side; but this is mentioned only for completeness since it shouldn't matter.

      I discovered this issue when my HOST-site curl(1) commands were failing like this*:*

      jdoe@HOST$ curl --insecure -X GET -H "Accept:application/json" localhost:28083/connectors/
      curl: (56) Recv failure: Connection reset by peer

      Please see below. Please help. Thank you.

       


      jdoe@HOST$ podman exec -it debezium_container /bin/bash
