[chef] Re: Newb Question on Deploy Resource

[Graham Christensen < >]

Hi David,

When using the timestamp deploy mechanism (putting the releases in a structure like this:  /my/path/releases/20130313024211) it prevents Chef from being idempotent.

Try switching to the deploy_revision strategy.

Sorry if this is a totally dumb question, but I can't seem to find the answer

out there. I was hoping to try and leverage the deploy resource for a simple

app I've got in git. I've been through the docs at

http://docs.opscode.com/resource_deploy.html and I have things working for the

most part.

The question I have is about expected behavior. It appears that every single

chef run the resource is taking action (including restarting the app) despite

the fact that no changes are pushed to the github repo. We run Chef client on a

schedule, so I'd hate to have the app "deployed" every time chef runs.

So my question is if this is expected or am I doing something wrong? On the

surface this sure doesn't feel very idempotent, and given the general push to

ensure resources are idempotent this caught me a little of guard.

Here is the uber basic recipe:

deploy "/my/path" do

repo "git://my_git/my_org/my_app.git"

migrate false

symlink_before_migrate({})

restart_command "service httpd restart"

end
