That seems to indicate that inside the deployment container DNS is not
working. Can you do the following to check:
oc run --image centos:7 test --generator=run-pod/v1 --restart=Never --
curl https://kubernetes
oc logs test
And then
oc run --image centos:7 test2 --generator=run-pod/v1 --restart=Never --
cat /etc/resolv.conf
oc logs test2
The latter should have a nameserver pointing to the master by its service
IP - the command:
oc get svc/kubernetes -n default
Should show that same IP

Hi,
I've been following the following steps to deploy metrics:
https://docs.openshift.org/latest/install_config/cluster_metrics.html
When I run the following command:
oc process -f metrics.yaml -v \
HAWKULAR_METRICS_HOSTNAME=hawkular-metrics.example.com,USE_PERSISTENT_STORAGE=false
\
| oc create -f -
I get the following error:

How can I know if my kubernetes master URL is
https://kubernetes.default.svc:443 or is another URL?
My Openshift installation isn't an update.
