AWS CloudFormation/CodePipeline Example

This project uses CloudFormation to spin up a CICD pipeline for Java applications using CodeBuild, CodeDeploy, CodePipeline, and an EC2 instance.

Launching the Stack

1. Before launching the stack, create a fork of this sample java application. It contains specifications on how CodeBuild and CodeDeploy should build and deploy the app.

2. Launch the CloudFormation stack by clicking this button:

3. Fill in the parameters and follow the prompts to complete the launch. For the GitHub user/repo/branch provide your GitHub username and the master branch of the fork you created in step 1. If you don't have a GitHub OAuth token, you can generate one here.

4. Watch and wait while CloudFormation provisions all of the resources required this stack. The process should take roughly 5 minutes.

5. When the stack is complete, retrieve the CodePipeline url from the output tab and navigate to it. A new revision will have triggered and should be making its way down the pipeline.

6. After the revision builds, click "Approve" on the approval gate to deploy it to the EC2 server

6. When the deployment completes, retrieve the EC2 instance public DNS name from the output tab of the CloudFormation stack. Then navigate to /petclinic.

Programmatically Approving a Pipeline Manual-approval-step

See put-approval-result directory for three ways to approve a manual approval step in a Code Pipeline.
The first way can be ran via Python 2.7 anywhere basic.py.
viaAlexa.py returns a result that is configured for Alexa.
viaIoT.py is meant to be utilized in a Lambda function triggered by an IoT Button.
