# py-push-server

## Docker Compose Setup

```
version: '3.1'

services:
  endorser-push-server:
    container_name: 'endorser-push-server'
    image: endorser-push-server:1.0
    build:
        context: ./py-push-server
    volumes:
      - /docker-volumes/pwa-push-server/data:/app/instance/data
    restart: always
    networks:
      - phoenix-network

networks:
  phoenix-network:
    external: true
```

On first run you need to:

`docker network create phoenix-network`


## HAProxy setup

... in docker-compose.yml ...

```

... in `haproxy-config/sites/web-push.anomalistlabs.com.cfg` ...

define an HAProxy backend and map it to the Docker host and port
NOTE:  this also turned off CORS origin rule
```
backend web_push_backend
  mode http
  compression algo gzip
  compression offload
  http-response set-header Access-Control-Allow-Origin "*"
  server server_nginx endorser-push-server:3000
```

... in `haproxy-config/maps/domains.map` ...

add a domain that will be used as a base

```
timesafari.anomalistlabs.com
```


... in `haproxy-config/maps/sites.map` ...

map the `/web-push` path to the `web_push_backend`
NOTE: `timesafari-pwa.anomalistlabs.com` PWA sits on the root

```
timesafari-pwa.anomalistlabs.com/web-push/ web_push_backend
```

## The rest ..

`docker-compose up -d` should just work :-)
