In addition to Jonas’ answer above; If you have more than one namespace, you need to specify the namespace your pod is currently using i.e kubectl exec -n <name space here> <pod-name> -it — /bin/sh After successfully accessing your pod, you can go ahead and navigate through your container.
Unfortunately Kubernetes’ volume system differs from Docker’s, so this is not possible directly. However, in case of a single file foo.conf you can use: a mountPath ending in this file name and a subPath containing this file name, like this: volumeMounts: – name: cephfs-0 mountPath: /opt/myapplication/conf/foo.conf subPath: foo.conf Repeat that for each file. But if … Read more
container_cpu_cfs_throttled_seconds_total is the sum of all throttle durations, i.e. durations that the container was throttled, i.e. stopped using the uses CFS Cgroup bandwidth control. Since each stopped thread adds its throttled durations to container_cpu_cfs_throttled_seconds_total, this number can become huge and does not help you (unless you have a known, fixed number of threads). That is … Read more
PersistentVolumeClaims will remain unbound indefinitely if a matching PersistentVolume does not exist. The PersistentVolume is matched with accessModes and capacity. In this case capacity the PV is 10Gi whereas PVC has capacity of 3Gi. The capacity in the PV needs to same as in the claim i.e 3Gi to fix the unbound immediate PersistentVolumeClaims issue.
To try and figure this out I would run the command: kubectl get pods – Add the namespace param if required. Then copy the pod name and run: kubectl describe pod {POD_NAME} That should give you some information as to why it’s stuck in the initializing state.
Are you running all these commands as a single line command? First of all, there’s no ; or && between those commands. So if you paste it as a multi-line script to your terminal, likely it will get executed locally. Second, to tell bash to execute something, you need: bash -c “command”. Try running this: … Read more
Pods that use emptyDir volumes without storage quotas will fill up this storage, where the following error is present: eviction manager: attempting to reclaim ephemeral-storage Set a quota limits.ephemeral-storage, requests.ephemeral-storage to limit this, as otherwise any container can write any amount of storage to its node filesystem. A sample resource quota definition apiVersion: v1 kind: … Read more
Am I missing something to delete POD using Pattern Match or with Wilcard? When using Kubernetes it is more common to use labels and selectors. E.g. if you deployed an application, you usually set a label on the pods e.g. app=my-app and you can then get the pods with e.g. kubectl get pods -l app=my-app. … Read more
