RE: Unable to connect with service using mysql-ephemeral template

ping mysql: unknown host mysql
nslookup mysql:                                                         
Server:         213.186.33.xx                                                  
Address:        213.186.33.xx#53                                                
** server can't find mysql: NXDOMAIN 
dig: answer 0

content of /etc/resolv.conf:

search test.svc.cluster.local svc.cluster.local cluster.local ovh.net

nameserver 213.186.33.xx

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

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?
