ping mysql: unknown host mysql
nslookup mysql:
Server: 213.186.33.xx
Address: 213.186.33.xx#53
** server can't find mysql: NXDOMAIN

This works fine (IP = service IP):
mysql -utest -ptest -h172.30.222.94
ping 172.30.222.94 PING

Is service DNS resolution otherwise working in your cluster?
if you just enter the container w/o starting the mysql shell are you able to
dig/nslookup/ping the mysql hostname?
can you check the /etc/resolv.conf settings within the container to ensure the
cluster DNS server is listed?

I've deployed the mysql-template which went fine:
Now I've a running mysql container. I go to the terminal inside my webconsole
to authenticate on my mysql container:
mysql -utest -ptest -h127.0.0.1
> mysql
Fine, but when I try my service as my host:
mysql -utest -ptest -hmysql
Error 2005 (HY000): Unknown MySQL server host 'mysql' (0)
My service above my container is called 'mysql'
Can someone explain this issue?
