Release Notes

prometheus/prometheus (prometheus/prometheus)

v3.10.0

Compare Source

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
