Quick Start

In a hurry? No problem! Here’s a quick start to get going.


gem install codebuild
cd <your-project>
cb init # generates starter .codebuild files
# edit .codebuild/buildspec.yml
cb deploy # create the CodeBuild project via CloudFormation
cb start  # start a CodeBuild project. Runs the buildspec.yml

What Happened?

Here are a little more details on what the summarized commands do. First, we install the codebuild tool.

gem install codebuild

Change into your project directory.

cd <your-project>

If you need a demo project, you can try this demo project: tongueroo/demo-ufo.

git clone https://github.com/tongueroo/demo-ufo demo
cd demo

Create the starter .codebuild files in the project.

cb init # generates starter .codebuild files

An important generated file .codebuild/buildspec.yml. The starter file looks something like this:

      - echo Build started on `date`
      - uptime

All it does is run a uptime command as part of the CodeProject build. Edit it for your needs. Remember to commit it and push it to the repo.

The CodeBuild project is defined in .codebuild/project.rb via the Project DSL. It looks something like this:

  JETS_ENV: "test"

To define a project, it is literally 3 lines of code. You can deploy it with a single command:

cb deploy

This deploys a CloudFormation stack that creates a CodeBuild project and IAM role. The IAM role permissions is defined in .codebuild/role.rb via the IAM Role DSL.

Once the stack is complete. You can start the CodeBuild project via the CLI or the CodeBuild console. Here is the CLI command:

cb start

Here’s what CodeBuild project output looks like:

Pro tip: Use the <- and -> arrow keys to move back and forward.
