no cluster found

Error message

no cluster found

What it means

RunGetAll returns this hard-coded error when client.GetCluster succeeds (no transport/state-store error) but returns a nil cluster, meaning no cluster with the given name exists in the state store. It is a sentinel-style message indicating lookup returned empty rather than an error.

Solutions

1. Run `kops get clusters` (or `kops get` with no args) to list clusters actually visible in the state store
2. Verify KOPS_STATE_STORE points at the correct location (s3://bucket etc.) and credentials/profile can read it
3. Use the exact full cluster name (FQDN) as registered, correcting typos
4. Recreate the cluster or import state if the cluster config was deleted

Example fix

// before
kops get all mycluster
// after
kops get clusters          # confirm name
kops get all mycluster.example.com

clusters, err := client.ListClusters(ctx, nil)
if err != nil { return err }
found := false
for _, c := range clusters {
    if c.ObjectMeta.Name == options.ClusterName { found = true; break }
}
if !found {
    return fmt.Errorf("cluster %q not found in state store; run 'kops get clusters' to list", options.ClusterName)
}

if cluster == nil {
    return fmt.Errorf("cluster %q not found", options.ClusterName)
}

cluster, err := client.GetCluster(ctx, name)
if err != nil { return err }
if cluster == nil {
    return fmt.Errorf("no cluster found for %q; check KOPS_STATE_STORE and exact cluster FQDN", name)
}

When it happens

Trigger: `kops get all <name>` where <name> does not match any cluster in the configured state store, or KOPS_STATE_STORE points at the wrong/empty location, or the cluster name is misspelled.

Common situations: Wrong KOPS_STATE_STORE env var (e.g. pointing at a different bucket or an unset default); typo in cluster name or missing full DNS name (must be exact, e.g. mycluster.example.com, not just mycluster); cluster was deleted; running from a different AWS profile/account so the bucket/objects are invisible.
