chef_locker is a Ruby gem that contains a script to prevent Chef clients from converging.
To install, declare something like the following in Chef:
chef_gem 'chef_locker'Note that if something like rvm is installed, you may have to create a wrapper script to unset some Ruby-related environment variables.
Run sudo -H chef_locker [message with reason why] in a screen/tmux session and wait
for Lock acquired to appear. Then detach from your screen/tmux session to keep Chef
stopped (ctrl+b d in tmux).
To remove the lock and reenable Chef again, kill the process (ctrl + c).
