blugrn

Dead simple blue/green deploys. Writing this was faster than me reading docs to figure out how to do it properly with other tools. And also was more fun.

Intended usage:

docker-compose.blu.yml

services:
  blu_app:
    volumes:
      - ./log:/usr/src/app/log
      - ./data:/usr/src/app/data
    image: ghcr.io/im-karina/my-image-name:latest
    platform: linux/amd64
    restart: always
    ports:
    - "8080:3000"

docker-compose.grn.yml

services:
  grn_app:
    volumes:
      - ./log:/usr/src/app/log
      - ./data:/usr/src/app/data
    image: ghcr.io/im-karina/my-image-name:latest
    platform: linux/amd64
    restart: always
    ports:
    - "8081:3000"
