Chainguard Container for git-iamguarded

A minimal Git image for use with Iamguarded charts.

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/git-iamguarded:latest

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

Usage

Chainguard's Git Iamguarded Image allows you to run ordinary Git commands in CI/CD pipelines and also locally via Docker, and is compatible with Iamguarded charts.

Docker Setup

To make sure you have the latest version of the Image available, start by running a docker pull command:

docker pull cgr.dev/ORGANIZATION/git-iamguarded

Then, run the Image with the --version flag to make sure the Image is functional:

docker run -it --rm cgr.dev/ORGANIZATION/git-iamguarded --version

You will receive output similar to this:

git version 2.43.0

Cloning a Repository Locally

Because your local system user's unique identifier might differ from that of the container, you'll need to set up special permissions for the target directory if you want to use this Image to clone repositories locally. Once you've configured these permissions, you'll be able to set up a volume and have the contents of the cloned repository replicated on your host machine.

First, create a target directory somewhere in your home folder and set the required permissions:

mkdir ~/workspace
chmod go+wrx ~/workspace

Now you can use docker run to execute the git clone command, using the directory you just set up as a volume shared between your local machine and the container Image:

docker run -it -v ~/workspace:/home/git --rm cgr.dev/ORGANIZATION/git-iamguarded clone https://github.com/chainguard-images/.github.git

Here, the volume is mounted to the /home/git directory in the container.

This will return output like the following:

Cloning into '.github'...
remote: Enumerating objects: 251, done.
remote: Counting objects: 100% (33/33), done.
remote: Compressing objects: 100% (23/23), done.
remote: Total 251 (delta 15), reused 22 (delta 10), pack-reused 218
Receiving objects: 100% (251/251), 216.59 KiB | 1.04 MiB/s, done.
Resolving deltas: 100% (88/88), done.

You can now check the contents of your workspace directory, where you will find the cloned repository:

ls -a ~/workspace/

.  ..  .github

If you do not want to make the destination directory world-writable, you can run the git executable inside the container with your UID, thus giving it access to the directory:

docker run -it -v ~/workspace:/home/git -u $(id -u) --rm cgr.dev/ORGANIZATION/git-iamguarded clone https://github.com/chainguard-images/.github.git

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.
