Clojure, ClojureScript and Shadow-cljs - Deploying to Elastic Beanstalk using CircleCi 2

clojure-clojurescript-shadow-cljs-aws-elasticbeanstalk-circleci.md

Please read this gist first: Deploying to Elastic Beanstalk via CircleCi 2.0

Here is my .elasticbeanstalk/config.yml config:

branch-defaults:
  master:
    environment: myapp-env

deploy:
  artifact: my-app.zip

global:
  application_name: mywebapp
  default_ec2_keyname: circleci-key-pair
  default_platform: Docker running on 64bit Amazon Linux/2.12.17
  default_region: eu-central-1
  sc: git

And this is .circleci/config.yml config:
