kubectl

问题 I just add kubectl wait --for=condition=ready pod -l app=appname --timeout=30s in the last step of BitBucket Pipeline to report any deployment failure if the new pod somehow producing error. I realize that the wait doesn't really consistent. Sometimes it gets timed out even if new pod from new image doesn't producing any error, pod turn to ready state. Try to always change deployment.yaml or push newer image everytime to test this, the result is inconsistent. BTW, I believe using kubectl

问题 I've created a local Kubernetes cluster using ansible. Everything is running but now I try to connect my kubectl with the cluster (in the VM's). My cluster is running on https://IP:6443 First I got: $ kubectl get pods The connection to the server localhost:8080 was refused - did you specify the right host or port? So I tried this solution: kubectl config set-credentials kubeuser/IP --username=kubeuser --password=kubepassword kubectl config set-cluster IP --insecure-skip-tls-verify=true -

问题 Before posting this question I followed this answer How to mimic '--volumes-from' in Kubernetes but it didn't work for me.

A part of the nginx.prod.conf : location ~* \.(jpeg|jpg|gif
