static-site

Amazon CloudFront CDK Python project!

This example creates the infrastructure for a static site, which uses an S3 bucket for storing the content.

The cdk.json file tells the CDK Toolkit how to execute your app.

This project is set up like a standard Python project. The initialization process also creates a virtualenv within this project, stored under the .venv directory. To create the virtualenv it assumes that there is a python3 (or python for Windows) executable in your path with access to the venv package. If for any reason the automatic creation of the virtualenv fails, you can create the virtualenv manually.

To manually create a virtualenv on MacOS and Linux:

$ python3 -m venv .venv

After the init process completes and the virtualenv is created, you can use the following step to activate your virtualenv.

$ source .venv/bin/activate

If you are a Windows platform, you would activate the virtualenv like this:

% .venv\Scripts\activate.bat

Once the virtualenv is activated, you can install the required dependencies.

(.venv) $ pip install -r requirements.txt

Before you deploy

Before you deploy this project, you should create an Amazon S3 bucket to store your site contents. The site contents (located in the 'site-contents' sub-directory) are deployed to the bucket.

For example,

(.venv) $ aws s3 sync ./static-contents/ s3://your-s3-bucket-for-static-content/

Deploy

At this point you can now synthesize the CloudFormation template for this code.

(.venv) $ export CDK_DEFAULT_ACCOUNT=$(aws sts get-caller-identity --query Account --output text)
(.venv) $ export CDK_DEFAULT_REGION=$(aws configure get region)
(.venv) $ cdk synth \
              --parameters S3BucketForStaticContents='your-s3-bucket-for-static-contents'

If you generate a CloudFormation template based on our current CDK app, you would see the plain CloudFormation Parameters section:

Parameters:
  S3BucketForStaticContents:
    Type: String
    Description: s3 bucket that the site contents are deployed to

Use cdk deploy command to create the stack shown above.

(.venv) cdk deploy \
            --parameters S3BucketForStaticContents='your-s3-bucket-for-static-contents'

To add additional dependencies, for example other CDK libraries, just add them to your setup.py file and rerun the pip install -r requirements.txt command.

Clean Up

Delete the CloudFormation stack by running the below command.

(.venv) $ cdk destroy

Useful commands

• cdk ls list all stacks in the app
• cdk synth emits the synthesized CloudFormation template
• cdk deploy deploy this stack to your default AWS account/region
• cdk diff compare deployed stack with current state
• cdk docs open CDK documentation
