       kubectl get pods --all-namespaces | grep -i mariadb-server | awk '{print $1,$2}' \
       | while read a b ; do kubectl get pod $b -n $a -o wide
       done

2. Connect to the indicated pod by providing the arguments specified for the CLI as shown below.

       kubectl exec <POD_NAME> -it -n utility -- mysql -h <IP> -u root -p<PASSWORD> \
              -e 'show databases;'
