Question

How to pass environment variables to Docker containers running in AWS Elastic Beanstalk multiple docker container configuration(different for different containers)?

Answer 1

Use the environment key in your container descriptions.

{
  "containerDefinitions": [
    {
      "name": "myContainer",
      "image": "something",
      "environment": [
        {
          "name": "MY_DB_PASSWORD",
          "value": "password"
        }
      ],
      "portMappings": [
        {
          "containerPort": 80,
          "hostPort": 80
        }
      ],
      "memory": 500,
      "cpu": 10
    }]
}
