Docker

The easiest way to try the HTTP cache is to run the docker container image. Simply write a docker-compose yaml file with a souin and a træfik services.

# your-souin-instance/docker-compose.yml
version: '3'

x-networks: &networks
  networks:
    - your_network

services:
  souin:
    image: darkweak/souin:latest
    ports:
      - 80:80
      - 443:443
    environment:
      GOPATH: /app
    volumes:
      - /anywhere/traefik.json:/ssl/traefik.json
      - /anywhere/configuration.yml:/configuration/configuration.yml

  traefik:
    image: traefik:v3.0
    command: --providers.docker
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
      - /anywhere/traefik.json:/acme.json

networks:
  your_network:
    external: true

You have write the Souin configuration YAML file.
Look at the configuration section to discover all configurable keys here.

default_cache:
  ttl: 10s
reverse_proxy_url: 'http://traefik' # If it's in the same network you can use http://your-service, otherwise just use https://yourdomain.com

From source

If you want to run the Souin standalone server from sources, you should clone the Souin repository and run the golang standalone server.

git clone https://github.com/darkweak/souin
cd souin/plugins/souin

You can edit the configuration located at plugins/souin/configuration to configure the HTTP cache server.
Look at the configuration section to discover all configurable keys here.
Then you can run the server.

go run main.go

With that your application will be able to cache the responses if possible and returns at least the Cache-Status HTTP header with the different directives mentionned in the RFC specification.

Simply run the following curl command to ensure everything is setup. (we ensure that domain.com is a local domain).

curl -i http://domain.com
