This is the back-end of a simple 2-tier app to demonstrate deploying [Docker] (www.docker.com)-based application on [AWS Elastic Beanstalk] (aws.amazon.com/elasticbeanstalk) through Shippable. To see the full functionality of the app, use the same steps to deploy the front-end of the app which is also on Aye0Aye called micro-www.

When this sample repo is enabled in Shippable, the CI process performs the following:

• Uses Docker to build the CI environment from a Dockerfile, pulling the base image from public Docker Hub repository "aye0aye/micro-image"
• Executes some basic CI tests
• Stores the test results and code coverage report
• Upon successful CI build:
  • Pushes the newly built Docker image to Docker Hub repository "aye0aye/micro-api"
  • Deploys the new image to an Elastic Beanstalk application

• API_PORT: Port used for app (default:80)
• LOG_LEVEL: Specifies log level for Winston console (silly, debug, verbose, info, warn, error). This microservice uses info and error messages only.
• SHUD_LOG_TO_FILE: true or false, specifies whether to save logs to logs.log

Before beginning, create a new application and environment in Elastic Beanstalk using the instructions available here.

In the shippable.yml, change the following values based on your EB application:

• AWS_EB_APPLICATION:yourElasticBeanstalkApplicationName
• AWS_EB_ENVIRONMENT=yourElasticBeanstalkEnvironmentName
• AWS_S3_BUCKET=yourS3BucketName
• AWS_S3_FOLDER=yourS3FolderName to upload deployment config files
• AWS_REGION=yourPreferredAwsRegion
• REGISTRY_ACCOUNT=yourDockerRegistryAccount
  • Note that this can be the account/registry URL for any valid Docker Registry
• ACCOUNT_IDENTIFIER=shippable.$REGISTRY_ACCOUNT
  • No changes needed
• AWS_DEPLOY_JSON=Dockerrun.aws.json.$ACCOUNT_IDENTIFIER.$AWS_EB_APPLICATION
  • No changes needed
• AWS_DOCKER_CONFIG=dockerconfig.$ACCOUNT_IDENTIFIER.$AWS_EB_APPLICATION
  • No changes needed
• secure variable 1: use the Shippable project settings page to encrypt your AWS_ACCESS_KEY_ID
• secure variable 2: use the Shippable project settings page to encrypt your AWS_SECRET_ACCESS_KEY
