etcd Distributed reliable key-value store for the most critical data of a distributed system
Chainguard Containers are regularly-updated, secure-by-default container images.
For those with access, this container image is available on cgr.dev:
docker pull cgr.dev/ORGANIZATION/etcd:latest
Be sure to replace the ORGANIZATION placeholder with the name used for your organization's private repository within the Chainguard Registry.
The default listening ports in etcd are 2379 and 2380.
To run a container listening on these ports, try:
docker run -p 2379:2379 -p 2380:2380 --rm cgr.dev/chainguard/etcd

By default this image runs as a non-root user named etcd with a uid of 65532.
The default data directory for this image is /var/lib/etcd, and that directory is write-able by the etcd user.
If you change the user, UID, or data directory, you'll need to ensure the user running the etcd process has permissions to that
directory.
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:
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.
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.
