How to set which system dns to use for container

[jronck]

Hello,

I've created two different dns with:

$> sudo container system dns create test1
$> sudo container system dns create test2

If I set default with container system property set dns.domain testX, I'm able to resolve my containers with container-name.testX

Is it possible to create a container and set which dns to use? Something like:

$> container run -d --rm --dns test1 --name nginx-a nginx # resolve to: nginx-a.test1
$> container run -d --rm --dns test2 --name nginx-b nginx # resolve to: nginx-b.test2

I tried to use:

  --dns <ip>              DNS nameserver IP address
  --dns-domain <domain>   Default DNS domain
  --dns-option <option>   DNS options
  --dns-search <domain>   DNS search domains

But I could not figure out.

Thanks for your help.

Ok, I found it 😄

$> container run -d --rm --name nginx-a.test1 nginx
$> container run -d --rm --name nginx-b.test2 nginx
