If you are using Cloud9, the CDK is already pre-installed but it will likely be a few versions old. Run the following commands from the Cloud9 terminal to remove your current version and install the latest one:
npm uninstall -g aws-cdk npm install -g aws-cdk
If the Cloud9 terminal returns an error, use the
npm install -g aws-cdk --force
Now, let’s create a folder within our sam-app directory where the pipeline code will reside.
cd ~/environment/sam-app mkdir pipeline cd pipeline
Initialize a new CDK project within the pipeline folder by running the following command:
cdk init --language typescript
Now install the CDK modules that we will be using to build a pipeline:
npm install --save @aws-cdk/aws-codedeploy @aws-cdk/aws-codebuild npm install --save @aws-cdk/aws-codecommit @aws-cdk/aws-codepipeline-actions npm install --save @aws-cdk/aws-s3
After a few seconds, our new CDK project should look like this:
If you are using Cloud9 and get an insufficent space or
ENOSPC: no space left on device error, you may resize your volume by using the following commands from your Cloud9 terminal.
wget https://cicd.serverlessworkshops.io/assets/resize.sh chmod +x resize.sh ./resize.sh 20
At this point, your project should have the structure below (only the most relevant files and folders are shown). Within the CDK project, the main file you will be interacting with is the pipeline-stack.ts. Don’t worry about the rest of the files for now.
sam-app # SAM application root ├── hello-world # Lambda code ├── samconfig.toml # Config file for manual deployments ├── template.yaml # SAM template └── pipeline # CDK project root └── lib └── pipeline-stack.ts # Pipeline definition └── bin └── pipeline.ts # Entry point for CDK project ├── cdk.json ├── tsconfig.json ├── package.json └── jest.config.js
bin/pipeline.ts file, which is your entry point to the CDK project, and change the name of the stack to sam-app-cicd.
Save the file.
