dirk is a tool to orchestrate command execution via the AWS Systems Manager Run Command feature.
dirk lets you describe commands you'd like to execute via AWS Systems Manager's Run Command feature with YAML files. At the moment, AWS does not support re-running previously executed commands. They are meant to be one-off, unscheduled actions and the operator then needs to rebuild the command invocation request by hand (either using the AWS Console or the awscli command line tool). This is cumbersome in my opinion. I created this tool to help make command invocation requests easier to run on the fly and easier to codify into version control.
You can download a prebuilt binary here.
USAGE:
dirk [OPTIONS]
FLAGS:
-h, --help Prints help information
-V, --version Prints version information
OPTIONS:
-b, --batch <INTEGER> Number of instances to execute command concurrently (default: 1)
-e, --execute <STRING> Command to execute
-i, --inventory <FILE> Inventory file for commands
-r, --region <STRING> AWS Region (Default: 'us-east-1')
Using dirk is easy. First, you need to create an inventory file for the command(s) you want to run. The file name you use will be the value you feed into -i or --inventory option. This file can contain as many YAML stanzas as you like as long as the name of each stanza is unique. Each stanza should look like the example below:
---
test:
batch: 1
parameters:
workingDirectory: ""
executionTimeout: "3600"
commands:
- "#!/bin/bash"
- "echo Hello World"
targets:
- key: tag:app
values: "demo"
- key: tag:env
values: "test"
These key/value pairs line up with specific parameters in the AWS Systems Manager API. To read more on what you can use for each value, please check out the AWS documentation.
The above example allows you to run dirk -i commands.yml -e test which will execute those bash commands on instances with the app:demo tag and the env:test tag.
