Cody is a AWS CodeBuild management tool. It simplifies creating and managing AWS CodeBuild projects with a powerful DSL. It has quickly grown to one of my favorite tools since creating it.
It only takes a few commands to get started with Cody. First, install the tool.
gem install cody
Then use cody init to “codify” your project.
$ cd project $ cody init create .cody create .cody/README.md exist .cody create .cody/buildspec.yml create .cody/project.rb $
The init command generates starter
.cody files that includes a
Let’s take a look at the buildspec.yml.
version: 0.2 phases: build: commands: - uptime
buildspec.yml just runs the
uptime command as an example to help you get started with CodeBuild.
AWS CodeBuild will pull from a GitHub repo. So you must push your changes to a GitHub repo. Create a GitHub repo and push your changes to your repo.
git add . git commit git remote add origin email@example.com:tongueroo/cody-demo # update with your info git push -u origin master
You also have to import your GitHub token so that CodeBuild has access to clone your repo. Details here: GitHub Oauth Token
The cody init command also created a
github_url("https://github.com/tongueroo/cody-demo") # update with your info linux_image("aws/codebuild/ruby:2.5.3-1.7.0") environment_variables( JETS_ENV: "test", )
Cody gets it down to only a few lines! Yet at the same time, it still gives you the full power to customize the project. On top of that, you have the power of the Ruby programming language at your finger tips.

We can use cody deploy to create CodeBuild project.
$ cody deploy Generated CloudFormation template at /tmp/codebuild.yml Deploying stack cody-demo-cody with CodeBuild project cody-demo Creating stack cody-demo-cody. Check CloudFormation console for status. Stack name cody-demo-cody status CREATE_IN_PROGRESS Here's the CloudFormation url to check for more details https://console.aws.amazon.com/cloudformation/home?region=us-west-2#/stacks Waiting for stack to complete 02:58:41AM CREATE_IN_PROGRESS AWS::CloudFormation::Stack cody-demo-cody User Initiated 02:58:44AM CREATE_IN_PROGRESS AWS::IAM::Role IamRole 02:58:45AM CREATE_IN_PROGRESS AWS::IAM::Role IamRole Resource creation Initiated 02:59:00AM CREATE_COMPLETE AWS::IAM::Role IamRole 02:59:02AM CREATE_IN_PROGRESS AWS::CodeBuild::Project CodeBuild 02:59:04AM CREATE_IN_PROGRESS AWS::CodeBuild::Project CodeBuild Resource creation Initiated 02:59:05AM CREATE_COMPLETE AWS::CodeBuild::Project CodeBuild 02:59:06AM CREATE_COMPLETE AWS::CloudFormation::Stack cody-demo-cody Stack success status: CREATE_COMPLETE Time took for stack deployment: 25s. $
The deploy command launches a CloudFormation stack to create and manage the CodeBuild project. It looks like this:
On the CodeBuild console it looks like this:
$ cody start cody-demo Build started for project: cody-demo Please check the CodeBuild console for the status. CodeBuild Log Url: https://us-west-2.console.aws.amazon.com/codesuite/codebuild/projects/cody-demo/build/cody-demo%3A8c9e640e-d97f-49f1-915a-9fed5d55b3f4/log $
It’s essentially the same thing as:
aws codebuild start-build --project-name cody-demo
You can see the CodeBuild run in the console.
Check out the build logs. To get there, click on Projects > Select Project > Click on Build Logs. When the build finishes you’ll see something like this:
You can see the
Cody provides a simple way to create CodeBuild projects. There’s a lot more power to the tool. For example, the type option allows you to create multiple CodeBuild projects associated with the same repo. You can fully control the IAM role permissions used. You can have the CodeBuild project execute on a scheduled basis. This article is meant to provide an introduction to the Cody tool.
The project source code for this blog post is available at: tongueroo/cody-demo.
