Preventing a deploy of tomcat from running again.

[Chris Brooks]

Hiya,

I've had a google for this but I can't find anything which answer my question...

I have a playbook which deploys tomcat via a zip file, this is the standard tomcat file from their website.

it then takes a template of server.xml and places it in the /opt/tomcat/conf directory.

This action changes the contents so the next time my playbook runs it re-runs the play which I don't want, is there an easy way around this?

This is the relevant section:-

a filename, when it already exists, this step will not be run. (added in Ansible 1.6)
