I'm running on this system:

With wksctl 0.8.1, I get this behavior:

failed to create SSH client: failed to connect to 127.0.0.1:2222: ssh: handshake failed: ssh: host key mismatch

For wksctl 0.8.2-alpha1, I modified cluster.yaml to remove spec.providerSpec.sshKeyPath Instead, I added to the setup.sh script:

wksctl apply --git-url="$(git_http_url "$(git_remote_fetchurl "${git_remote}")")" --git-branch="$(git_current_branch)" --ssh-key ${SCRIPT_DIR}/$cluster_key ${git_deploy_key}

I get the same error:
