imeq/nginx repository overview

Nginx with blue/green deployment working as reverse proxy. Http request with context /api will be forwarded to API_SERVICE_NAME - LIVE:API_SERVICE_PORT

⁠Default values:

LIVE=blue (blue/green)
API_SERVICE_NAME=api
API_SERVICE_PORT=8080
API_TIMEOUT=60
API_HEALTH_URI=/api/management/health

⁠How to use it:

Mount volume to /app with index.html file. Set env LIVE to green.

docker-compose up -d backend-green
docker-compose up -d nginx
⁠Update image
docker-compose pull backend-blue
docker-compose up -d backend-blue
⁠Wait for backend service

docker-compose exec nginx ./alive

HEALTH_URI must return json: {"status": "UP"}

Change LIVE variable to blue

docker-compose up -d nginx
docker-compose stop backend-green
⁠Switch api manually

docker-compose exec nginx ./switch.sh green

⁠Example docker compose

services:
    backend-green:
       extends:
           file: docker-compose.backend.yml
           service: backend
    backend-blue:
        extends:
            file: docker-compose.backend.yml
