Cron Morse 24 hour Announcer Docker

This project sets up a Docker container that runs a cron job every hour to play Morse code audio files using mpg123 and ALSA. The container is based on Alpine Linux.

Features

• Runs a cron job every hour to execute a Morse code script.
• Uses mpg123 and ALSA for audio playback within the Docker container.
• Configurable time zone and audio device mappings.

Prerequisites

Before you begin, ensure you have the following installed:

• Docker
• Docker Compose

Getting Started

1. Clone the Repository

   git clone https://github.com/9M2PJU/Cron-Morse-24-hour-Announcer.git
   cd Cron-Morse-24-hour-Announcer
   

2. Set Up the Environment

   Ensure Docker and Docker Compose are installed on your system. Follow the installation instructions if needed.

3. Build the Docker Image

   Build the Docker image using Docker Compose:

   docker compose build
   

4. Run the Container

   Start the Docker container in detached mode:

   docker compose up -d
   

5. Access the Container

   To enter the container and inspect or debug:

   docker run -it --rm --device /dev/snd morse_cron /bin/sh
   

Configuration

• Time Zone: The container uses the Asia/Kuala_Lumpur time zone. You can adjust the TZ environment variable in the docker-compose.yml file if needed.
• Audio Device: ALSA sound device is mapped to the container. Ensure your host system’s sound device is accessible by Docker.

Troubleshooting

If you encounter issues:

• Verify that the /start-cron.sh script is present and executable.

• Check ALSA configuration on both the host and inside the container.

• Inspect container logs for errors:

  docker logs <container_id>
