Config

Generate centrifugo config in root folder:

bin/centrifugo genconfig

Adjust allowed_originsif you use other ip/port than 127.0.0.1:8080

{
    "port": 8001
    "allow_anonymous_connect_without_token": true,
    "token_hmac_secret_key": "<SAME RANDOM SECRET AS IN CENTRIFUGO_SECRET IN env>",
    "admin": true,
    "admin_password": "<WITH THIS KEY YOU CAN LOGIN IN ADMIN PANEL>",
    "admin_secret": "71e55876-5178-4f54-963b-796fb49387ca",
    "api_key": "<SAME RANDOM SECRET AS IN CENTRIFUGO_API_KEY IN env>",
    "allowed_origins": [
        "http://127.0.0.1:8080"
    ],
}

Place env file elswere and reference path to this file in docker run --env-file. Generate random tokens e.g. with openssl rand -hex 32 and place them in both config.json and env file. Adjust WEBSOCKET_URL if you use other port than 8010

APP_ENV=prod
APP_SECRET=GENERATE_RANDOM_SECRET

CENTRIFUGO_API_KEY=<SAME RANDOM SECRET AS IN api_key IN config.json>
CENTRIFUGO_SECRET=<SAME RANDOM SECRET AS IN token_hmac_secret_key IN config.json>

Use it

Run it with http://127.0.0.1:8080/ If you not use localhost, you must adjust cors in centrifugo config.json file.

Use local built docker image in synology nas when same architecture

Export file to archive when build with the same architecture

docker save sfdownloader | gzip > sfdownloader.tar.gz

Import archive on synology at docker/image

##Alternatively build docker image direct on synology Log in via ssh, chdir to /volume1/docker clone via

git clone git@github.com:ThomasTr/Symfony-Downloader.git sfdownloader

build:

cd sfdownloader
sudo docker build --no-cache -t sfdownloader .

Image is then available in docker images frontend.
