DDEV Laravel Reverb configuration

I have been trying to get this addressed so my Laravel application can talk to Laravel Reverb.

This is what I have for my docker-compose.reverb.yaml file:

services:
  reverb:
    labels:
      com.ddev.site-name: ${DDEV_SITENAME}
      com.ddev.approot: ${DDEV_APPROOT}
    container_name: "ddev-${DDEV_SITENAME}-reverb"
    ports:
      - '${REVERB_SERVER_PORT:-8080}:8080'
    build:
      context: .
      dockerfile: reverb/Dockerfile
    working_dir: /var/www/html
    depends_on:
      - redis

and this is what I have for my .ddev/reverb/Dockerfile

WORKDIR /var/www/html

RUN docker-php-ext-configure pcntl --enable-pcntl \
  && docker-php-ext-install \
    pcntl

EXPOSE 8080

CMD [ "php", "artisan", "reverb:start", "--host=0.0.0.0" ]

After more tinkering and with the help of @rfay of DDEV and @Jsh, this is my working solution:

Update ~/.ddev/config.yaml to both expose the ports + deploy the daemon

web_extra_exposed_ports:
  - name: vite
    container_port: 5173
    http_port: 5172
    https_port: 5173
  - name: reverb
    container_port: 8080
    http_port: 8081
    https_port: 8080
web_extra_daemons:
  - name: vite
    command: bash -c 'npm install && npm run dev -- --host'
    directory: /var/www/html
  - name: reverb
    command: bash -c 'php artisan reverb:start'
    directory: /var/www/html

In my Laravel ~/.env file:

APP_HOST="myproject.ddev.site"
REVERB_APP_ID=1234
REVERB_APP_KEY=1234
REVERB_APP_SECRET=abcd
REVERB_HOST="${APP_HOST}"
REVERB_PORT=8080
REVERB_SCHEME=https

VITE_REVERB_APP_KEY="${REVERB_APP_KEY}"
VITE_REVERB_HOST="${REVERB_HOST}"
VITE_REVERB_PORT="${REVERB_PORT}"
VITE_REVERB_SCHEME="${REVERB_SCHEME}"

The solution that is working did not require any custom docker-compose config, nor a Dockerfile.

NOTE: Be mindful in not using APP_URL because this will include the protocol, https, where you want to only have the host because it will be connecting over ws: or wss: for the protocol.
