| # Introduction | ||
| [Docker](https://www.docker.com) packages software into standardized units for development, shipment and deployment. | ||
|
|
||
| This folder brings you the files needed to run the encoders (audio and PAD), the multiplexer and the modulator through containers. 3 docker images are available from the [docker registry](https://hub.docker.com). They can be ran on amd64, arm64 and arm/v7 architectures: | ||
| - [opendigitalradio/encoders](https://hub.docker.com/r/opendigitalradio/encoders) | ||
| - [opendigitalradio/dabmux](https://hub.docker.com/r/opendigitalradio/dabmux) | ||
| - [opendigitalradio/dabmod](https://hub.docker.com/r/opendigitalradio/dabmod) | ||
|
|
||
| # One-time setup | ||
| 1. Install Docker on the host that will run the containers | ||
| 1. Clone this repository or copy the dab-scripts/docker directory on the host | ||
| 1. Adapt file `config/odr-dabmod.ini` to match your transceiver hardware and local RF spectrum | ||
| 1. Adapt file `odr.env` to suit your configuration. Then run the following command: | ||
| ``` | ||
| source odr.env | ||
| ``` | ||
| # Customized setup (changing the sample configuration) | ||
| 1. Adapt file `config/ODR-encoders.conf` to suit your needs | ||
| 1. Adapt file `config/odr-dabmux.info` to match the content of file `config/ODR-encoders.conf` | ||
| 1. Adapt the structure of directory `config/mot` to match the content of file `config/ODR-encoders.conf` | ||
| # Operations | ||
| 1. Create a docker volume, named `odr` with the configuration files: | ||
| ``` | ||
| docker run \ | ||
| --interactive \ | ||
| --tty \ | ||
| --rm \ | ||
| --volume $(pwd)/config:/mnt/source \ | ||
| --volume odr:/mnt/dest \ | ||
| ubuntu:22.04 \ | ||
| bash -c "cd /mnt/source ; cp -R * /mnt/dest" | ||
| ``` | ||
| 1. Start broadcasting the DAB/DAB+ ensemble (3 containers, named `odr-encoders`, `odr-dabmux` and `odr-dabmod`) | ||
| ``` | ||
| docker compose up --detach | ||
| ``` | ||
| 1. Stop broadcasting the DAB/DAB+ ensemble | ||
| ``` | ||
| docker compose down | ||
| ``` |
