• EC2 Container Registry and Elastic Beanstalk Single environment application with docker engine

Change aws config in gradle.properties:

groupName=icoder
awsECRName=YOUR_EC_REPOSITORY_NAME
awsId=YOUR_AWS_ID
awsEBSApp=YOUR_ELASTIC_BEANSTALK_APPLICATION_NAME
awsRegion=eu-central-1

Building project

gradle clean build -Penv=local

Starting embedded server

Server will be running on default port 8080

gradle startServer

Starting unit tests:

gradle test

Starting integration test with arquillian:

Before tests docker compose hast to be started because you may need an local data store which you can run in docker.

Run compose once:

gradle dockerCompose

Then start tests:

gradle itest

Starting/stopping docker server

gradle startDocker
gradle stopDoker

Publishing to ecr repository

This command creates elastic beanstalk application deployment version and publish baked container to EC2 Container Repository:

gradle clean publishToECR -Penv=prod 

Example running apps manually:

You can simply run them as jar applications or you can configure your ide to run jar application so you can debug it.

gradle build -Penv=local
java -jar ./pajara-micro.jar --deploy ./build/libs/starter-1.0.0.war

note if you did not download payara micro run

gradle downloadPayaraMicro
