[chef] Re: Triggering remote actions based on new nodes

[Charles Sullivan < >]

You should use Chef Search   to do this.  Have your DB server look for servers to add rules for based on any criteria you want...

Hi folks,

I've looked around to find answers on this, but haven't been successful, so apologies if it's a FAQ.

We're automating the buildout of a Rails application with Chef, migrating from a partially-implemented Puppet installation.  Things are going well, but we're reaching the endgame and would like to remove a few last manual steps.

We have tools in place to build and configure a node.  However, when a new node comes online, we have a few things that need to happen on other systems.  We need firewall rules updated on database and memcache servers, and we also need MySQL GRANT statements run to allow the node to connect to the database.

Is there a way to have that happen - to notify the memcache servers to update their firewall rules, run statements on the MySQL server, etc?  It seems like this problem would be solved in terms of helping automate scale out, but we haven't found the answer yet.
