Hello,

I want to run a check in my playbook for the current version of ruby package installed and if its not the version Im expecting then fail the play.

How can I go about doing this?

Thanks

Mike

An example of what I think might work.

- name: Verify ruby version is 1.9

shell: echo /opt/vagrant\_ruby/bin/ruby --version

register: status

- fail: “This is bad version”

when: var=status.stdout\_lines != “1.9”

try this:

&nbsp;&nbsp;&nbsp;- name: Verify ruby version is 1.9  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;shell: /opt/vagrant\_ruby/bin/ruby --version |awk '{print $2}'  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;register: status

&nbsp;&nbsp;&nbsp;- fail: "This is bad version"  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;when: status.stdout|version\_compare("1.9", "eq")

`echo` is not needed as `ruby --version` already prints to screen, but  
you really only want the version number which is what awk is doing  
i use version\_compare filter as it will match 1.9.x minor versions  
also, if you don't want this add a ,strict=true to the filter to make  
sure it is purely 1.9.
