'Error: snapshot missing hash but --skip-hash-check=false' when performing `rke etcd snapshort-restore` with .zip extension included in snapshot name

Article Number: 000020214

Environment

A Kubernetes cluster provisioned with the Rancher Kubernetes Engine (RKE) CLI

Situation

When performing an etcd snapshot restore via RKE, including the `.zip` file extension in the snapshot name parameter, i.e. `rke etcd snapshot-restore --name snapshot.zip` and a snapshot filename of `snapshot.zip`, the restoration fails with an error of the following format:

FATA[0020] [etcd] Failed to restore etcd snapshot: Failed to run etcd restore container, exit status is: 128, container logs: Error: snapshot missing hash but --skip-hash-check=false

Resolution

This issue is caused by the incorrect inclusion of the .zip file extension to the snapshot name parameter.

The snapshot name parameter (--name) should contain the snapshot name, excluding the file extension.

In the example of a snapshot filename of snapshot.zip the correct name parameter is therefore just snapshot, i.e. rke etcd snapshot-restore --name snapshot.
