Document DNS queries in tenant #93

Open NissesSenap opened 2 years ago

NissesSenap commented 2 years ago

We have seen through out the years that you should define fqdn when performing internal communication when possible, for example: service-nr-one.tenant.svc.cluster.local

This should be document under developer somewhere.

Now we are talking small adjustments but it might be worth talking about ndots config in kubernetes yaml. As long as you use fqdn this should decrease the dns query time.

  dnsConfig:
    options:
       - name: single-request-reopen
       - name: ndots
         value: "2"
