Using Docker

Single Container

  • Run your application as a single docker container
  • Either provide:
    • Dockerfile: Elastic Beanstalk will build and run the Docker container
    • Dockerrun.aws.json (v1): Describe where already built docker image is along with the other essential details like ports, volumes etc and Beanstalk will deploy the container for us on EC2 instances.
      • Must be at the root of source code.
Beanstalk in Single Docker Container DOES NOT use ECS.

Multi Container

  • Multi Docker helps run multiple containers per EC2 instance in EB
    • attachments/Pasted image 20220516152016.jpg
  • This will create for you:
    • ECS Cluster
    • EC2 instances, configured to use the ECS Cluster
    • Load Balancer (in high availability mode)
    • Task definitions and execution
  • Requires a config Dockerrun.aws.json (v2) at the root of source code
    • It should be a JSON file only it cannot be a YAML file.
  • Dockerrun.aws.json is used to generate the ECS task definition.
  • Your Docker images must be pre-built and stored in ECR for example.
