DNS Issues

[AlexWeinstein92]

Summary

Ultimately my goal is to let my pods communicate with each other via service name. I have been told this should be easily possible with any kubernetes environment, but have not been able to figure it out with microk8s. When I exec into a service shell and curl, I consistently get hostname could not be resolved.

Right now I am also dealing with a pod startup error after doing microk8s enable dns. I have not editted the config file (configmap/coredns) in any way. I am not sure if this is related to my inability to curl between pods.

/etc/coredns/Corefile:20 - Error during parsing: Unknown directive 'pods'

What Should Happen Instead?

After the coredns pod starts correctly, I should be able to exec into a pod and then curl [servicename:serviceport] with expected answers.

However, I may be overestimating the need for coredns here - please let me know if it is not necessary for for this task.
