opsworks_local

Run OpsWorks recipes via command line. By default, the recipe targets the EC2 instance where the command was run, but this can be changed.

Usage

Non-EC2 machines (e.g. local development)

For Non-EC2 machines, either the instance ids or the stack must be explicitly state.

# Invoke deploy on one instance
$ ruby opsworks_local.rb -c deploy -i i-7f9811b1

# Invoke deploy on multiple server instances
$ ruby opsworks_local.rb -c deploy -i i-1a2abcd4,i-0b2cbac5

# Run custom recipe to current instance
$ ruby opsworks_local.rb -r mycookbook::jump_high -i i-7f9811b1

# Update custom cookbook
$ ruby opsworks_local.rb -c update_custom_cookbooks -i i-7f9811b1

# Update custom cookbook for all instances in the stack `my_stack`
$ ruby opsworks_local.rb -c update_custom_cookbooks -s my_stack

##EC2 machines opsworks_local can introspect, and dynamically obtain OpsWorks infromation regarding the current EC2 instance. This removes the necessity of either doing lookups, or hard-coding instance ids.

# Deploy all applications to current instance
$ ruby opsworks_local.rb -c deploy

# Invoke deploy on all servers for the stack where this instance belongs.
$ ruby opsworks_local.rb -c deploy -a

# Update custom cookbook on all servers for the stack this instance belongs.
$ ruby opsworks_local.rb -c update_custom_cookbooks -a

# Works perfectly on your `crontab`, especially with the `cron` Chef resource.
# Chef Name: postgresql backup

Prerequisites

• aws-cli package must be installed.

Design Goals

Initially, the goal of this script is to enable an OpsWorks recipe to be run as a cron job. The cron job will be deployed via the cron resource of Chef/OpsWorks. Thus, I wanted a dependency-free, bloat-free script that can be placed anywhere, and made to run by any system user via a simple line of script. This means no Gemfiles, and no bundling.

I also intentionally did not use the aws-sdk gem, due to the reasons above.
