Setup

  • Install and setup serverless.
  • Install deps (run yarn).
  • Create .env file. (required configs: PRODUCTION_URL_APP, MONGO_URL_TEST, MONGO_URL, Amazon_accessKeyId, Amazon_secretAccessKey, EMAIL_SUPPORT_FROM_ADDRESS)
  • Also you can create .env.production file for production deploy.

Deploy

  • Development deploy: Run sls deploy
  • Production deploy: Run NODE_ENV=production sls deploy
  • If files did not change: Add --force
  • Deploy particular function: NODE_ENV=production sls deploy function --function checkUserInactivity --force
  • invoke locally weeklyStat, only staging MongoDB: sls invoke local -f weeklyStat -e ONLY_MONGO_URL=1

Testing (run/invoking)

  • For invoking checkCardExpiration locally run sls invoke local -l -f checkCardExpiration.
  • For invoking checkCardExpiration run sls invoke -l -f checkCardExpiration.

Cloudformation

If stack inside Cloudformation is in UPDATE_ROLLBACK_FAILED state, it will not recover. You have to delete all associated resources (most likely, lambda functions and S3 buckets), then delete stack, then deploy all lambda functions with NODE_ENV=production sls deploy. AWS Cloudformation will create a new stack.
