Watch your Docker registry project size, then monitor it with Grafana.

To use this tool, you will need:

• grafana
• influxdb
• python3 with influxdb lib installed

1. Install influxdb lib with pip install influxdb
2. Download registry-watch.py from this repo and edit L8-L11 to fit your InfluxDB configuration
3. Add this to your crontab, like this: * * * * * python3 /path/to/registry-watch.py /path/to/data/registry/docker/registry/v2
4. Configure Grafana to use this data
   1. Set up Variables called project_name with query SHOW TAG VALUES FROM <HERE_IS_YOUR_MEASUREMENT_NAME> WITH KEY = "project"
   2. Set up panel with SELECT mean("size") FROM "<HERE_IS_YOUR_MEASUREMENT_NAME>" WHERE ("project" =~ /^$project_name$/) AND $timeFilter GROUP BY time($__interval) fill(null), and make it repeat on $project_name
