Only need to do it once

$ pip install awsebcli six

# Change to the source directory
$ cd app

$ eb init --profile ${AWS_PROFILE}
# - Region: sydney
# - Application name: SampleService
# - Platform version: Docker 17.03.1-ce (or latest)
# - ssh key: my-sampleservice-key

$ eb create SampleService-dev --cname sampleservice-dev --vpc
# See also http://docs.aws.amazon.com/elasticbeanstalk/latest/dg/eb-cli3-getting-started.html
# - Environment Name: SampleService-dev
# - DNS CNAME prefix: sampleservice-dev
# - Load balancer type: application

1. To build and test the Docker image for the application. You need to install docker if you want to run it locally:

   $ cd deploy
   $ ./eb_deployment_helper.sh --build-image 
   

2. To also deploy the application and update settings/configurations within EC2 instances:

   $ cd deploy
   $ ./eb_deployment_helper.sh --build-image \
         [--push-image] \
         --eb-deploy --eb-env [EB_ENV_NAME]
   

3. To update Elastic Beanstalk Environment for instant change in After Creation state:

   1. Make sure you have the latest EB environment first. Because aws:elasticbeanstalk:managedactions:platformupdate is enabled, the Docker/platform version in Platform:PlatformArn can be different from the last saved *.cfg.yml file.

      $ cd app/
      $ eb use [EB_ENV_NAME]              # Ensure all operations take effect to a specific EB environment
      $ eb config delete [EB_ENV_NAME]    # Delete the named saved configuration (in EB S3)
      $ eb config save [EB_ENV_NAME]      # Save the environment configuration settings for the current running
                                          # environment to .elasticbeanstalk/saved_configs/ with the filename
                                          # [EB_ENV_NAME].cfg.yml.
      

   2. Edit app/.elasticbeanstalk/saved_configs/[EB_ENV_NAME].cfg.yml.

   3. Create Pull Request for review.

   4. Apply the change

      $ cd deploy
      $ ./eb_deployment_helper.sh --eb-config-update --eb-env [EB_ENV_NAME]
      

eb ssh [EB_ENV_NAME] --profile [profile-name]

eb logs --all

You can use a certificate stored in IAM with Elastic Load Balancing load balancers and CloudFront distributions.

Otherwise create yours:

1. Your profile should have the following permissions
   1. iam:UploadServerCertificate
   2. iam:ListServerCertificates

CALL aws iam upload-server-certificate ^
  --server-certificate-name elastic-beanstalk-x509 ^
  --certificate-body file://example.com.crt ^
  --private-key file://example.com.key ^
  --certificate-chain file://intermediate.crt ^
  --profile k-eb-deploy

:: Show all certificates
CALL aws iam list-server-certificates --profile k-eb-deploy

For details see Update a certificate to IAM.

If no .ebignore is present, but a .gitignore is, the EB CLI will ignore files specified in the .gitignore. If an .ebignore file is present, the EB CLI will not read the .gitignore.

For details see EB .ebignore.
