Control Groups

Manage control groups (cgroups) via chef!

Supported platforms

• Debian 12
• Ubuntu 24.04

See LIMITATIONS.md for the researched support policy and unsupported platforms.

Current unit verification passes on this repository. The Kitchen suites (default, entry, and rule) run on Debian 12 and Ubuntu 24.04 with manage_runtime false because Dokken/cgroup-v2 containers cannot start the legacy libcgroup mount workflow. See LIMITATIONS.md for the runtime caveat.

Maintainers

This cookbook is maintained by the Sous Chefs. The Sous Chefs are a community of Chef cookbook maintainers working together to maintain important cookbooks. If you’d like to know more please visit sous-chefs.org or come chat with us on the Chef Community Slack in #sous-chefs.

Example usage

control_groups_install 'default'

control_groups_entry 'lackresources' do
  memory('memory.max' => '1048576')
  cpu('cpu.max' => '10000 100000')
end

control_groups_rule 'someuser' do
  controllers %w(cpu memory)
  destination 'lackresources'
end

This will restrict all processes created by someuser into the lackresources control group.
