Feature Friday #10: cf-support

Found a bug, asking for help? Use cf-support to collect info quickly. cf-support was born from interactions supporting Enterprise customers to streamline data collection and was introduced in late 2022 with the release of 3.18.31 and 3.21.02. Furthermore, it was featured on The Agent is In3 episode 21 Troubleshooting with cf-support. It gathers various details about the system and creates an archive that you can attach to your ticket. While its inception was geared towards Enterprise customers, it’s still both useful and available for community users as well.

Feature Friday #6: cf-promises

Will your policy work? cf-promises can check the CFEngine policy for syntax errors and give you an overview of the host’s context. It’s always a good idea to check your policy for syntax errors. Consider this policy file: /tmp/ bundle agent feature_friday { reports: "$(this.promise_filename)" printfile => cat( "$(this.promise_filename)" ) } Can you spot the error? Let’s see if cf-promises can help: command cf-promises -f /tmp/ output /tmp/ error: syntax error } ^ /tmp/feature-friday-6.

Feature Friday #5: cfbs

Do you maintain multiple policy sets? Do you leverage policy written by others? Ever wished for an easier way to upgrade your policy framework? cfbs can help to improve all of these cases. cfbs is a command line tool that aims to help simplify managing a policy set and working with CFEngine Build, a website for finding and sharing modules. A policy set usually - but not always - builds on top of some base, like the Masterfiles Policy Framework (MPF).

Migrating to cfbs

Traditionally, CFEngine policy sets are managed as a whole. When upgrading the Masterfiles Policy Framework (MPF)1 users must download the new version of the policy framework and integrate it into the existing policy set, carefully diffing the vendored policy files against their currently integrated policy. Updates to policy authored by others must be sought out and similarly integrated. The burden is on the user to maintain the knowledge of where policy is sourced, if updates are available, and how it is integrated into the policy set as a whole.
