Virtual Waiting Room on AWS

Site wrapper to absorb and control user traffic flowing into smaller web sites.

Prerequisites for Customization

  • Install/update to Python 3.x
  • Install the AWS Command Line Interface (CLI)
  • Create a Python virtual environment using requirements.txt and activate it
  • Configure the bucket name of your target Amazon S3 distribution bucket

Building distributable for customization

  • Configure the bucket name of your target Amazon S3 distribution bucket
export DIST_OUTPUT_BUCKET=<MY-BUCKET-NAME> # bucket where customized code will reside
export SOLUTION_NAME=my-solution-name
export VERSION=my-version # version number for the customized code

Note: You would have to create an S3 bucket with the prefix '-'; is where you are testing the customized solution. Also, the assets in bucket should be publicly accessible.

  • Now build the distributable:
cd deployment
chmod +x ./build-s3-dist.sh 
./build-s3-dist.sh $DIST_OUTPUT_BUCKET $SOLUTION_NAME $VERSION 
  • Deploy the distributable to an Amazon S3 bucket in your account. The head-bucket command verifies that your account owns the bucket. Note: you must have the AWS Command Line Interface installed.
aws s3api head-bucket --bucket <MY-BUCKET-NAME>-<AWS-REGION> --expected-bucket-owner <AWS-ACCOUNT-ID>
aws s3 sync regional-s3-assets/ s3://<MY-BUCKET-NAME>-<AWS-REGION>/$SOLUTION_NAME/$VERSION/  
  • Get the link of the solution template uploaded to your Amazon S3 bucket.
  • Deploy the solution to your account by launching a new AWS CloudFormation stack using the link of the solution template in Amazon S3.

Running unit tests for customization

  • Some packages require a build before unit tests will run
  • Install the common package into the virtual envronment before running
cd ./deployment
chmod +x ./run-unit-tests.sh 
./run-unit-tests.sh
