WHAT

inject a port for postgresql container generated by the getFreePort method instead of the random one generated by Testcontainers.

WHY

The order in which components are generated is:

• configuration for the runtime (with ports generated by getFreePort method)
• postgres instance is generated
• postgres instance is started on a random port
• the connector runtime is started

so if postgres runs on a port that was already be used for the runtime configuration, the runtime then cannot be started because of port conflict.

generating the postgres port with getFreePort should fix the issue

FURTHER NOTES

• removed unused service in the workflow
