Chainguard Container for prometheus

Chainguard image for Prometheus, a systems and service monitoring system.

Chainguard Containers are regularly-updated, secure-by-default container images.

Download this Container Image

For those with access, this container image is available on cgr.dev:

docker pull cgr.dev/ORGANIZATION/prometheus:latest

Be sure to replace the ORGANIZATION placeholder with the name used for your organization's private repository within the Chainguard Registry.

Compatibility Notes

Chainguard's Prometheus image is meant to serve as a drop-in replacement for both the prom/prometheus image and the bitnami/prometheus image. Like most other Chainguard images, the production variant of the Prometheus image comes with only the minimum dependencies needed to function and does not include things like a shell or package manager.

Getting Started

Chainguard's Prometheus image requires a Prometheus configuration file in order to run. It comes with an example configuration file, which is found within the container at /etc/prometheus/prometheus.yml. The values from this example can be found in the Prometheus source tree.

You can test out the image using the example configuration file with the following command. Note that you will need to change ORGANIZATION to align with the name of your organization's private repository within the Chainguard registry:

docker run -p 9090:9090 cgr.dev/ORGANIZATION/prometheus:latest --config.file=/etc/prometheus/prometheus.yml

. . .
time=2024-12-13T01:10:13.001Z level=INFO source=main.go:1224 msg="Server is ready to receive web requests."
time=2024-12-13T01:10:13.001Z level=INFO source=manager.go:168 msg="Starting rule manager..." component="rule manager"

The default port that Prometheus listens on is 9090. By including -p 9090:9090 in the previous command, the application will be exposed on the host at port 9090. You can use your web browser to check whether the Prometheus application is indeed running by navigating to localhost:9090.

Alternatively, you can use a Prometheus configuration file stored locally by mounting a volume, like this:

docker run -p 9090:9090 -v /path/to/local/prometheus.yml:/prometheus.yml cgr.dev/ORGANIZATION/prometheus:latest

What are Chainguard Containers?

Chainguard Containers are minimal container images that are secure by default.

In many cases, the Chainguard Containers tagged as :latest contain only an open-source application and its runtime dependencies. These minimal container images typically do not contain a shell or package manager. Chainguard Containers are built with Wolfi, our Linux undistro designed to produce container images that meet the requirements of a more secure software supply chain.

The main features of Chainguard Containers include:

• Minimal design, without unnecessary software bloat
• Daily builds to ensure container images are up-to-date with available security patches
• High quality build-time SBOMs attesting to the provenance of all artifacts within the image
• Verifiable signatures provided by Sigstore
• Reproducible builds with Cosign and apko (read more about reproducibility)

For cases where you need container images with shells and package managers to build or debug, most Chainguard Containers come paired with a -dev variant.

Although the -dev container image variants have similar security features as their more minimal versions, they feature additional software that is typically not necessary in production environments. We recommend using multi-stage builds to leverage the -dev variants, copying application artifacts into a final minimal container that offers a reduced attack surface that won’t allow package installations or logins.
