Usage: deploy.sh [-h] [-d] [-v VERSION] deploy/build/delete environment stack

Light weight version of cdk.sh in cloud-base

positional arguments:
  deploy                builds and deploys the stack to target environment, environment must be supplied.
  delete                deletes the stack from target environment, environment must be supplied.
  build                 only builds the Lambda & synthesizes CDK (useful when developing)
  diff                  show difference between running environment and the template generated from code
  stack                 name of the stack (BastionStack, DatabaseStack, NetworkStack or All)
  environment           Environment name (tuotanto, testi or kehitys)

optional arguments:
  -h, --help            Show this help message and exit
  -d, --dependencies    Clean and install dependencies before deployment (i.e. run npm ci)
  -v VERSION, --version VERSION
                          Frontend version to deploy (e.g. -v ci-256)
