Sample deployment

Edit docker compose configuration (docker-compose.yml)

version: '2'

    image: atexio/mercure
    restart: always
      - 8000:8000
      SECRET_KEY: '<random value>'
      URL: ''
      EMAIL_HOST:  ''
      - /etc/localtime:/etc/localtime:ro
      - ./data/database:/code/database
      - ./data/media:/code/media
      - ./data/migrations/phishing:/code/phishing/migrations

To generate the SECRET_KEY variable, you can use this command:

# generate random SECRET_KEY
cat /dev/urandom | tr -dc 'a-zA-Z0-9' | fold -w 200 | head -n 1

The SECRET_KEY is used as a salt for Django password hashing, don’t change it after using it with Mercure. After changing the secret key, you can run the container with this command:

docker-compose up -d

Next, you can create a superuser to log into the web interface:

# create super user
docker-compose exec front python createsuperuser
