[rvm] Best practice for cron jobs?

[Chad Woolley]

What's the best practice for invoking ruby scripts usign rvm in a cron
job? Googled a bit, and found one reference, but wondering if there's
some official docs...

Thanks,

Hi Chad,

Currently that doc page is a story in tracker which I am hoping to get to soon.

The gist of the 'best practice' is to use what is called a wrapper
script, something like:

#!/usr/bin/env bash

source (wherever scripts/rvm is)

rvm X # select a ruby, can use a gemset if you need.

# NOW do the actual task, cd to project root if necessary.
# Note that if you are using a project rvmrc file the cd should
# also take care of the ruby selection above :)

This ended up working for me, I didn't need a wrapper script:

* * * * * myuser bash --login -c 'cd /path/to/myapp && ruby
./script/myscript.rb'

Unfortunately, this same trick doesn't work for monit. I'll open a
separate thread for that...

Thanks,

Yes that 'trick' should work fine for cronjobs and is one of the ones
I use myself.

Nicely done!
