clusterctl boot grub set

Point a node’s GRUB configuration at a target

Synopsis

Link the GRUB configuration a node loads over TFTP to an installation target.

GRUB looks for a file named after the node’s address in hexadecimal, which is what this command computes. Unlike a PXE boot path, the link has no one-shot form: GRUB loads the target at every boot until “boot grub unset” removes it.

TARGET is a file on the TFTP host, relative to services.tftp.grubPath unless it is absolute. It has to exist and to lie under services.tftp.root, which is all the TFTP server serves. The link is written relative to its directory, so that a TFTP server confined to its root follows it too.

Options inherited from parent commands

      --config strings        configuration file or directory to read, repeatable (default: CLUSTERCTL_CONFIG or the search path)
      --context string        context to act on (default: the current one)
      --dry-run               report what would be done and change nothing
      --fanout int            how many hosts to work on at once, at least 1; caps the service processors and the names asked at once too, which fanout.max and CLUSTERCTL_FANOUT do not (default: from the configuration)
      --force                 allow protected hosts, and nodes the inventory does not know, to be touched
  -n, --nodes stringArray     node set to act on, for example 'exe[1-10],@rack:R02' (default: CLUSTERCTL_NODES)
  -o, --output string         output format: table, wide, json, yaml, nodeset, name, jq= (default "table")
      --progress string       how to show the progress of a command on standard error: auto, tty, counter, plain, none (default: CLUSTERCTL_PROGRESS, else auto, a live tree when standard error is a terminal; plain writes lines for a log)
      --progress-log string   append the progress events of a command to this file, one JSON object per line, created readable by you alone (default: CLUSTERCTL_PROGRESS_LOG; an empty one writes none)
      --set stringArray       override one configuration value as PATH=VALUE, repeatable
  -y, --yes                   answer the confirmation prompts with yes
