In case of rabbitmq container is unhealthy
let's use `ss` command instead of `netstat` as
``netstat`` is not present in distros anymore and
in containers we already have iproute2 [debian/ubuntu]
and iproute [rhel based] package installed.

+ echo 'rabbitmq - netstat -an'
rabbitmq - netstat -an
+ sudo docker exec rabbitmq netstat -an
OCI runtime exec failed: exec failed: unable to start container process: exec: "netstat": executable file not found in $PATH: unknown
