I have used Kompose
to generate my kubernetes deployment files. All the pods are running bare two. However, they show no error except this.
Unable to attach or mount volumes: unmounted volumes=[taiga-static-data taiga-media-data], unattached volumes=[kube-api-access-9c74v taiga-gateway-claim0 taiga-static-data taiga-media-data]: timed out waiting for the condition

It is a problem with mounting the volume, I am certain as it seems from an earlier error that taiga-back
and taiga-db
share a volume.
This is the Kompose

Perhaps if I can fix one I can figure out the other pod as well. This is the application

CodePudding user response:
You most likely have not configured your PVCs right and the container is trying to mount the claim, but the claim is not bound to a PV.
CodePudding user response:
Please make sure that taiga-static-data & taiga-media-data pvcs are bound to their respective pvs.
CodePudding user response:
The issue was that the persistent volumes are not bound to the pod hence the pod is failed to start. Ensure the storage is configured and the persistent volumes are created.
