This utility runs the provided command after setting environment variables based on $CONFIG_ENV and passed options.

Note: Usage examples assume package usage. Otherwise, replace set-env with node index.js

Usage: $ set-env <options> -- '<shell command>'

Example: "set-env -a -e -- 'aws ecr get-login-password --region us-west-2 | docker login --username AWS --password-stdin $ECR_ID.dkr.ecr.us-west-2.amazonaws.com'"

Example: "set-env -e -u -- 'docker build -t $ECR_ID.dkr.ecr.us-west-2.amazonaws.com/repo-name:$BUILD_ID .'"

Example: "set-env -e -i -- 'docker push $ECR_ID.dkr.ecr.us-west-2.amazonaws.com/repo-name:$BUILD_ID'"

$CONFIG_ENV can be one of dev, stag, or prod.

• The -a option sets AWS_PROFILE
• The -e option sets ECR_ID
• The -i option sets BUILD_ID based on the current value (more on that in a minute)
• The -u option sets BUILD_ID after incrementing it by one and writing the new number back to the file
• The -v options checks that a .env.$CONFIG_ENV file is located in the process current working directory

Note: -i and -u options cannot be passed together.

ECR_ID and BUILD_ID values are retrieved from samconfig.toml parameter_overrides under the table header matching the $CONFIG_ENV.deploy.parameters. For example, dev.deploy.parameters.

ECR_ID comes from the ID at the beginning of the ImageRepo value. BUILD_ID comes from BuildID.

AWS profiles are retrieved from a file called './profiles.js'. This file should default export an object with dev, stag, and prod keys and the corresponding values.

If a PIPELINE environment variable is detected, AWS_PROFILE will not be set even if the option is passed.

Note: The program looks for samconfig.toml and profile.js files in the current working directory of the node process.

Example profiles.js:

module.exports = {
  dev: <your_dev_profile>,
  stage: <your_staging_profile>,
  prod: <your_production_profile>
}

To use as a package run npm pack and npm install the tarball in a project.
