Hello All, At the meeting on August 25th, we discussed an issue with the puppet-httpd module and a few solutions. The issue is that the httpd_mod type does not have a baked-in ordering relationship with the Service['httpd'] resource. This means that sometimes httpd_mod resources are instantiated after the service attempts to come up, meaning the service cannot start.
A few solutions have been proposed: 1) Modify our use of the httpd_mod resource to use 'before' everywhere. This patch [1] is an example of doing that for puppet-gerrit, we'd have to perform similar modifications elsewhere in our code. 2) Modify the httpd module to do this automatically. This patch [2] changes the type at the ruby layer using puppet internal apis to add an 'autobefore' on the Service['httpd'] resource. 3) Create an httpd::mod defined type that can do this automatically. We'd have to then change every invocation of httpd_mod to be httpd::mod. This patch [3] is the patch to create httpd::mod and this patch [4] shows what using it would be like. We'd have to apply changes like [4] everywhere in our infrastructure. 4) Migrate to puppetlabs-apache. This has two forms, one(4a) involving patching that module to support our usecase and the other(4b) where we use the existing api. I have my own opinions about what we should be doing, but this message is meant to explain the problem and roads available to us, not to editorialize.
