Monocker

Features

• Telegram integration
• Pushbullet integration
• Pushover integration
• Discord integration (via webhooks)
• Monitors 'state' changes for all containers (every 10 seconds)
• Specific inclusions or exclusions of containers to monitor

Future Considerations

• Additional messaging platform support

LABEL_ENABLE

This is an optional value, and defaults to false if it is not specified. This feature allows you to specify (with labels) 'either' specific containers to monitor or exclude from monitoring.

• If it is set to false, then all containers will be monitored except for ones with the following label in their YAML.

    labels:
      monocker.enable: 'false'

• If it is set to true, only containers with the following label will be monitored

    labels:
      monocker.enable: 'true'

• If you just want to monitor everything, then set LABEL_ENABLE: 'false' or just leave it out altogether.
