Hi @bdkdavid,
Assuming you meant that one pod goes to CrashLoopBackOff... is this behavior observed immediately after the linkerd inject of the ingress? If linkerd is 2.11.3, what command was run to inject the ingress?
Regards,
-Chris0 -
Yes
The command:
kubectl get ds myingress-ingress-nginx-controller -o yaml | linkerd inject --ingress - | kubectl apply -f -Also
it seems to be just on that node : all the pods on the other nodes seem to be fine
the myingress-ingress-nginx-controller pods seem to be working alsothe node 3 has 1/2 where the onthers have only 1
I built all the nodes the same configs not sure why that is having a problem
Also I have some screen shots:
why is it only showing one functioning?Here are some screen shots

Hi @bdkdavid,
Please use the linkerd inject command as recommended here. The additional options will allow for all the ingress controller pods to be successfully injected and reach running state. This is a minor change that needs to be considered for linkerd 2.11, but it was not needed for the earlier version 2.10.
Regards,

do i need to uninstall and reinstall or can I just apply it?

I uninstalled with helm and applied command:
kubectl get ds myingress-ingress-nginx-controller -o yaml | linkerd inject --ingress --skip-inbound-ports 443 --skip-outbound-ports 443 - | kubectl apply -f -Works Now!

Hi @bdkdavid,
The
kubectl get ds ... | linkerd uninject ... | kubectl apply -f -
was another option to reverse the ingress controller injection.Regards,
-Chris0
