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 the prom/prometheus image. Like most other Chainguard container 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:

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

Note that you will need to change ORGANIZATION to align with the name of your organization's private repository within the Chainguard registry.

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's free tier of Starter container images are built with Wolfi, our minimal Linux undistro.

All other Chainguard Containers are built with Chainguard OS, Chainguard's minimal Linux operating system 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 development, or -dev, variant.

In all other cases, including Chainguard Containers tagged as :latest or with a specific version number, the container images include only an open-source application and its runtime dependencies. These minimal container images typically do not contain a shell or package manager.

Although the -dev container image variants have similar security features as their more minimal versions, they include additional software that is typically not necessary in production environments. We recommend using multi-stage builds to copy artifacts from the -dev variant into a more minimal production image.

Need additional packages?

To improve security, Chainguard Containers include only essential dependencies. Need more packages? Chainguard customers can use Custom Assembly to add packages, either through the Console, chainctl, or API.

To use Custom Assembly in the Chainguard Console: navigate to the image you'd like to customize in your Organization's list of images, and click on the Customize image button at the top of the page.
