In kind, when we bind-mount a host directory it is first mounted into the kind container at /mnt, then into the pod at the desired location. We accidentally picked this up for full-blown k8s, and were creating volumes at /mnt. This changes the behavior for both kind and regular k8s so that bind mounts are only allowed if a fully-qualified path is specified. If no path is specified at all, a default storageClass is assumed to be present, and the volume managed by a provisioner. Eg, for kind, the default provisioner is: https://github.com/rancher/local-path-provisioner ``` stack: test deploy-to: k8s-kind config: test-variable-1: test-value-1 network: ports: test: - '80' volumes: # this will be bind-mounted to a host-path test-data-bind: /srv/data # this will be managed by the k8s node test-data-auto: configmaps: test-config: ./configmap/test-config ``` Reviewed-on: cerc-io/stack-orchestrator#741 Co-authored-by: Thomas E Lackey <telackey@bozemanpass.com> Co-committed-by: Thomas E Lackey <telackey@bozemanpass.com>
