This repo builds container images for Nightscout.
Release tags are automatically updated by Renovate bot, so new Nightscout releases will be available in this repository within a few hours.
The base flavor does not make any changes to the Nightscout source code.
The WebSocket flavor configures the Nightscout client to prefer WebSocket connections instead of HTTP long-polling.
For Docker, I'd suggest copying the compose.yaml in this repository, then adding any environment variables you desire from Nightscout's documentation.
I have built a Helm chart for Kubernetes deployments. See charts.gabe565.com or gabe565/charts for details.
