compose-to-batch

A CLI tool to transform a docker-compose.yml into an AWS Batch job definition.

This tool allows you to develop your job code on your laptop using docker:

$ docker-compose up

And then when you're ready to deploy to AWS Batch:

$ docker-compose config | compose-to-batch > job-definition.json
$ aws batch register-job-definition --cli-input-json file://job-definition.json

usage

install

npm install -g compose-to-batch

given the following docker-compose.yml

version: "2"
services:
  my-job:
    build: .
    image: 12345678910.dkr.ecr.us-east-1.amazonaws.com/my-job:0.1.0
    environment:
      REGION: us-east-1
    labels:      
      composeToBatch.vcpus: 2
      composeToBatch.memory: 2000
      composeToBatch.jobRoleArn: arn:aws:iam::12345678910:role/my-role

running the following command

cat docker-compose.yml | compose-to-batch

will output the following

{
  "jobDefinitionName": "my-job",
  "type": "container",
  "containerProperties": {
    "image": "image: 12345678910.dkr.ecr.us-east-1.amazonaws.com/my-job:0.1.0",
    "environment": [
      {
        "name": "REGION",
        "value": "us-east-1"
      }
    ],
    "vcpus": "2",
    "memory": "2000",
    "jobRoleArn": "arn:aws:iam::12345678910:role/my-role"
  }
}
