k3d adds cluster restart command

Introduced 2026-06-02 · score 0.97

HOW TO USE IT

When restarting a k3d cluster, run `k3d cluster restart <name>`; omit the name to target the default cluster, or use `--all` to restart every cluster.

WHY THIS HELPS

Restart a k3d cluster while working with multiple clusters.

REQUIREMENTS AND LIMITATIONS

• Version: v5.9.0
• NAME: Cluster name; accepts multiple names. Defaults to `k3s-default` when omitted.
• --all, -a: Restart all existing clusters.
• --wait: Wait for servers and load balancer to be ready before returning; defaults to true.
• --timeout: Maximum wait time before canceling or returning; defaults to 0 seconds.
• Docs conflict: The v5.9.0 command reference lists cluster start and stop but omits restart; the v5.9.0 command implementation defines `cluster restart`.
