Deployment

To deploy the pipeline for the first time, you'll need a GitHub secret name github-oauth-token in your Secrets Manager and then you can deploy it using cdk deploy. After the first deploy, any change that you push to your Git Repository will update the Pipeline and execute.

This project also uses two SSM parameters: /eks-cdk-pipelines/hostZoneId (String) and /eks-cdk-pipelines/zoneName (String). You can use parameters.sh to interactively include your parameters.
