Graceful exit mid chef run

Chef Infra (archive)

Hi All,

I there a graceful way to exit a chef run (skill all remain cookbooks/recipes) if a condition is not met.

Scenario:

Recipe 1
Recipe 2 (condition not met)
Recipe 3 Skip
Recipe 4 Skip

Use would be where a manual sysadmin step is need prior to continuing.

I’m looking for a way to prevent a tangled web of only_if/not_if statements.

I’ve tried using native ruby alert(“message here”) but it exits abruptly, and chef run is not reported back to server.

Hello,

Sorry for top-post; our runlist_modifiers cookbook allows for one to raise
a RestrictedRecipe error, which unfurls the run-list so to speak, so that
dependant (or depended-upon) recipes are also skipped. 0

Cheers,

You can also simply "return" from your recipe when some condition not met:

return if node[:platform_family] == "debian"

The HeavyWater cookbook is much more robust, but this does the job.
