[feature request] allows to tag each line of the manifest for processing

[arussel]

Use case: we're using spiceweasel mainly to deploy cluster in ec2 with manifest looking like: cookbooks:

• foo -bar environments:
• production
• test roles:
• r1
• r2 nodes: -ec2 1: clusters:
• production: -ec2 1: XXX -ec2 2:

The problem is:

• we don't want to delete cookbooks, envs ... each time we want to delete the nodes
• we want to be able to tell if all the cluster needs to get up or only some nodes (typically, we have few hundreds workers that needs to be brought down/up) each time, but we want to keep the DB node untouch.

We tried to get around this by creating multiple manifest file, but we still need have to include in the file the env used in the cluster.

I understand our use case diverge from the main purpose of spiceweasel (batch loading Chef infrastructure), but by just adding tag or similar capabilities, we would be able to manage our clusters with it. Something like: cookbooks [create]: roles [create]: environments[create]: nodes:

• ec2 1 [dbcreate,create] cluster [*]

and running: spiceweasel -t create => run everything spiceweasel => run only cluster spiceweasel -t dbcreate => run the node create/delete

I was thinking about doing something simple like adding flags for "--cookbooks", "--environments", "--roles", "--data-bags", "--nodes" and "--clusters" to only perform the actions on the flags that were passed. So if you had a complex manifest but only wanted to reload your roles, you'd run

spiceweasel --roles infrastructure.yml

and it would do

knife role from file foo knife role from file bar ....

that would be nice, giving the ability we already have to specify a cluster file, this would probably meet a lot of use case.

Added support in the branch here: https://github.com/mattray/spiceweasel/tree/switches

Still trying to sort out fixing the tests, blocking on this: https://github.com/opscode/mixlib-shellout/issues/61

Merged into the 2.8 branch for the next release. Supported with --only
