clusterctl dns lookup

Resolve the host names of a node set

Synopsis

Resolve each node’s host name and print every address that comes back, and every alias passed through on the way.

With –bmc, each node’s service processor is resolved instead: the bmcAddress the inventory records for it, else the name the naming rules give it, which is the host the bmc commands reach. A bmcAddress that is an address is shown as it is and not looked up.

The names are resolved services.dns.maxConcurrent at a time, 16 by default, or fewer when –fanout is lower, and listed in the order of the nodes whatever order the answers came in.

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
