[chef] Re: compile vs execution phase

[Sean OMeara < >]

This problem comes up almost every day for me.

What needs to happen is.. recipe A needs to converge before recipe B compiles.

You can manually manipulate run_contexts if you're brave enough to go mucking around in Chef internals..

or...

There is a library cookbook called "now" on the community site that provides a hack for you.

Check out the integration tests for a usage example

I've been working on learning how to write cookbooks using chef-solo.  I have created two cookbooks, one that evaluates the physical array controllers and configures, partitions, luks_encrypts, mkfs and mounts the drives to /data/1, /data/2, /data/3, etc...  This works really well on a new machine and puts the hardware in a state we are looking for no matter how many drives there are or what their sizes are.

I also have a simple cassandra cookbook that installs an fpm version of cassandra, runs a template of the cassandra.yaml and creates the data directories depending on what drives are mounted to /data/1 /data/2 /data/3 etc...

done similar to:

#attributes file

default[:datadirs] = []

Dir.foreach("/data") do |drives|

  next if drives.match(/^\.\.?$)

  if system "/bin/mountpoint /data/#{drives}>/dev/null" then

    default[:cassandra][:data_dirs].push( "/data/#{drives}/cassandra/data" )

  end

end

#recipe

node[:cassandra][:data_dirs].each do |data_dir|
  directory "#{data_dir}" do

    owner "cassandra"

    group "cassandra"

    mode 0750

    action :create
    recursive true
  end
end

Of course this is getting generated at compile time when nothing is in /data.  The disks cookbook runs and populates /data/# however, the cassandra cookbook wont work unless there is a way to regen the recipe after the disk cookbook has completed.  running chef-solo a second time gets things into a proper state.

Is there a better way to create the directories?  I think I can use the lazy attribute assignment to make my template work, but the directory creation is giving me hell.

Thanks for any help
