The missing OpsWorks CLI

OpsWorks CLI

The missing OpsWorks CLI, run commands across stacks (and across regions), check your instances, apps, deployments, ELBs, with a smart filtering system.

Installation

npm install -g opsworks

Usage

opsworks <command> [args]

The OpsWorks CLI has multiple commands, similar to git, apt-get or brew. When you run opsworks with no arguments, you get an interactive prompt.

GUI / Prompt

For simple tasks, just use opsworks without a command and you'll get an interactive prompt.

Configuration

opsworks needs to access the AWS API using your credentials. Just like the AWS SDK or CLI, it will look for credentials in two places :

• From the shared credentials file (~/.aws/credentials)
• From environment variables

To use the credentials file, create a ~/.aws/credentials file based on the template below :

[default]
aws_access_key_id=your_access_key
aws_secret_access_key=your_secret_key

Commands

command	description
stacks	list OpsWorks stacks
deployments	list OpsWorks deployments
instances	list instances
apps	list apps
elbs	list Elastic Load Balancers
update	update cookbooks
setup	run setup recipes
configure	run configure recipes
deploy	deploy specified app
recipes	run specified recipes

Shared options for these commands

• -f Specify filter (see below)
• -u Update cookbooks before running the command
• -y Do not ask for confirmation

Note: by default, when you do not specify -y, the CLI will display a summary of what commands it will run and on which layer of which stacks as a precaution.

Filtering

Any opsworks command accepts filters. There are three built-in filters :

field	description
layer	The Shortname of the layer
stack	The Name of the stack
region	The stack's region

The format is field:filter,field2:filter2,... You can use wildcards, or even use regexes.

For example the command bellow would match all stacks whose name contain wordpress, and only include their database layer.

opsworks instances -f 'stack:*wordpress*,layer:database'

Using regexes to check ELBs of two wordpress stacks at once :

opsworks instances -f 'stack:(prod|staging)-wordpress'

Additionally, if you use custom JSON on your stacks or layers, you can use arbitrary filters. For example, if your custom JSON has an env variable, this would work :

opsworks instances -f 'env:production'
