# ichor machine reclaim

Reset a configured Talos machine of another cluster back to maintenance mode

### Synopsis

Reclaim a machine that already runs a configured Talos, so that Ichor can join it.

The machine is inspected with YOUR talosconfig (read from --talosconfig, used
only for this command, never stored and never printed). Ichor refuses a machine
that is already in an Ichor cluster, and a control plane whose removal would
break its cluster's etcd quorum (override: --force plus the cluster name typed
a second time). The reset is graceful (cordon, drain, leave etcd) when the
foreign cluster is reachable; for a dead cluster pass --force-ungraceful.

The reset wipes only the STATE and EPHEMERAL partitions and reboots.
User disks are not touched; they are listed, and encrypted ones are called out
because their keys may be gone.

Without --talosconfig, give --cluster NAME: the machine is then an orphan of that Ichor
cluster (its TalosMachine was deleted, which wipes on remove, so it still
carries the cluster's configuration) and the controller wipes it with the credentials Ichor
already holds for that cluster, deletes its Kubernetes Node and, afterwards, this command
registers it as a pending machine. A machine that still has an approved TalosMachine is
refused: use "ichor node remove". Needs the "reclaim" verb on machinereclaims.

Consent is the machine's UUID, typed at the prompt or given as --confirm. --yes
does not satisfy it.

Afterwards the machine comes back in maintenance mode with the same UUID. With
--cluster NAME its address is added to that cluster's spec.discovery.addresses
so that Ichor registers it as a pending machine. A pending TalosMachine of the same
UUID that an earlier reclaim left is kept: on its next pass (within about five
minutes) discovery re-probes the node and records the new maintenance certificate
and disks on that same machine (Event MaintenanceIdentityRefreshed); approve it after that.

```sh
ichor machine reclaim ADDRESS (--talosconfig FILE | --cluster NAME) [flags]
```

### Options

```text
      --cluster string           TalosCluster (in --namespace) whose discovery addresses get the machine's address afterwards
      --confirm string           the machine's UUID, for non-interactive use (--yes does not replace it)
      --confirm-cluster string   the foreign cluster's name, the second confirmation --force needs
      --context string           talosconfig context to use (default: the file's own)
      --force                    allow a control plane whose removal breaks etcd quorum, or is the last one
      --force-ungraceful         reset without cordon, drain and etcd leave, for a dead cluster
  -h, --help                     help for reclaim
      --wait duration            how long to wait for maintenance mode (0 to not wait) (default 10m0s)
```

### Options inherited from parent commands

```text
      --bundle-passphrase-file string   file holding the passphrase of the local secrets bundle; any readable path, e.g. /dev/fd/3; otherwise $ICHOR_BUNDLE_PASSPHRASE, then a prompt on a terminal. Never a value on the command line
      --ca-file string                  PEM file of the CA that signed ichor-ui's serving certificate, when ichor-ui serves TLS (env ICHOR_CA_FILE)
      --ichor-namespace string          namespace Ichor is installed in (where ichor-ui runs and the secrets bundle lives) (default "ichor-system")
      --kubeconfig string               path to the kubeconfig for the cluster's Kubernetes API; defaults to $KUBECONFIG, then ~/.kube/config
      --local                           do not use ichor-ui; compute from the Kubernetes API directly
  -n, --namespace string                namespace of the Ichor resources the command names (default "ichor-system")
  -o, --output string                   output format: "yaml" or "json" for scripts; by default a command prints for people (commands without a human view print YAML)
      --override                        incident only: override a safety check (reset a node, restore etcd, reboot or shut down the last worker, an upgrade the compatibility table refuses); needs the override RBAC verb on the resource; implies --local
      --talosconfig string              path to the talosconfig used to reach each node's Talos API; defaults to $TALOSCONFIG, then ~/.talos/config
      --tls-server-name string          name on ichor-ui's serving certificate, when it is not the Service's DNS name (<service>.<namespace>.svc)
      --yes                             skip interactive confirmation before a dangerous operation
```
