Kubernetes stuck on ContainerCreating
kubectl describe pods will list some (probably most but not all) of the events associated with the pod, including pulling of images, starting of containers.
kubectl apply vs kubectl create?
Those are two different approaches: Imperative Management kubectl create is what we call Imperative Management. On this approach you tell the Kubernetes API what you want to create, replace or delete, not how you want your K8s cluster world to look like. Declarative Management kubectl apply is part of the Declarative Management approach, where changes that you may have applied … Read more

Failed to find a valid digest in the ‘integrity’ attribute for resource on a deployed emberjs application
Ember uses Subresource Integrity (SRI) by default to increase the security of applications built with the framework.

It works by allowing … Read more

Pod status as `CreateContainerConfigError` in Minikube cluster

When I do helm install followed by kubectl get pods I see the MySQL pod status as running, but the Sonarqube pos status shows as CreateContainerConfigError. I reckon … Read more
pod has unbound PersistentVolumeClaims
You have to define a PersistentVolume providing disc space to be consumed by the PersistentVolumeClaim. When using storageClass Kubernetes is going to enable “Dynamic Volume Provisioning” which is not working with the local file system. To solve your issue: Provide a PersistentVolume fulfilling the constraints of the claim (a size >= 100Mi) Remove the storageClass from the PersistentVolumeClaim or provide it with an empty value (“”) Remove the StorageClass from … Read more
My kubernetes pods keep crashing with “CrashLoopBackOff” but I can’t find any log
As @Sukumar commented, you need to have your Dockerfile have a Command to run or have your ReplicationController specify a command. The pod is crashing because it starts up then immediately exits, thus Kubernetes restarts and the cycle continues.
Restart container within pod
Is it possible to restart a single container Not through kubectl, although depending on the setup of your cluster you can “cheat” and docker kill the-sha-goes-here, which will cause kubelet to restart the “failed” container (assuming, of course, the restart policy for the Pod says that is what it should do) how do I restart … Read more
