ForkableClient
Like modifying code on the fly? Like reworking internals of running code to do interesting things? Like not losing a huge chunk of memory because some jerk cookbook decided to load a 100M json file just for the hell of it? Then this cookbook is for you!
What's it do?
This cookbook adds forking support to chef-client runs. It is based on the work within this ticket. After this cookbook has loaded, client runs will fork themselves and then converge. What this provides is less worry about what cookbooks may be doing (and loading) that is going to bloat out the memory of the process. It's just that simple.
How do I use it?
Just add it to your node's run list (and probabably restart your daemon if it's currently running)
knife node run_list add my.amazing.node recipe[forkable_client]
Single runs
This cookbook does not work for single runs. It requires an interval based run (daemonized if you'd like), as the first run will fail by design. The reason for the failure is that we need to adjust how the client performs the run, and we don't want it to attempt to converge the node before we get the modifications applied. So a first run will end with something like this:
ERROR: Running exception handlers
FATAL: Saving node information to /var/cache/chef/failed-run-data.json
ERROR: Exception handlers complete
ERROR: ForkedClientInsertion: Chef client is now forkable. This is a non-fatal error.
FATAL: Stacktrace dumped to /var/cache/chef/chef-stacktrace.out
ERROR: Sleeping for 5 seconds before trying again
But the next run will show the new functionality at work:
INFO: Forking chef instance to converge...
INFO: Fork successful. Waiting for new chef pid: 16231
INFO: Forked instance now converging
INFO: *** Chef 0.10.10 ***
...
INFO: Chef Run complete in 4.34858479 seconds
INFO: Running report handlers
INFO: Report handlers complete
INFO: Forked instance completed. Exiting.
INFO: Forked converge complete
