prometheus

Prometheus now offers a distroless Docker image variant alongside the default busybox image. The distroless variant provides enhanced security with a minimal base image, uses UID/GID 65532 (nonroot) instead of nobody, and removes the VOLUME declaration. Both variants are available with -busybox and -distroless tag suffixes (e.g., prom/prometheus:latest-busybox, prom/prometheus:latest-distroless). The busybox image remains the default with no suffix for backwards compatibility (e.g., prom/prometheus:latest points to the busybox variant).

For users migrating existing named volumes from the busybox image to the distroless variant, the ownership can be adjusted with:

docker run --rm -v prometheus-data:/prometheus alpine chown -R 65532:65532 /prometheus

Then, the container can be started with the old volume with:

docker run -v prometheus-data:/prometheus prom/prometheus:latest-distroless

User migrating from bind mounts might need to ajust permissions too, depending on their setup.

[CHANGE] Alerting: Add alertmanager dimension to following metrics: prometheus_notifications_dropped_total, prometheus_notifications_queue_capacity, prometheus_notifications_queue_length. #16355

[FEATURE] PromQL: Add fill() / fill_left() / fill_right() binop modifiers for specifying default values for missing series. #17644
[FEATURE] Web: Add OpenAPI 3.2 specification for the HTTP API at /api/v1/openapi.yaml. #17825
[FEATURE] Dockerfile: Add distroless image variant using UID/GID 65532 and no VOLUME declaration. Busybox image remains default. #17876
