Chainguard Container for s3proxy

S3Proxy allows applications to access other storage backends via the S3 API, supporting providers like the local filesystem, Google Cloud Storage, and Azure Blob Storage.

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/s3proxy:latest

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

Compatibility Notes

The s3proxy Chainguard Container is based on the upstream S3Proxy project with the following differences from the upstream gaul/s3proxy Docker image:

• This image runs as a non-root user (uid 65532) by default, so the default listen port is 8080 instead of 80.
• The image uses a minimal set of packages, without a shell or package manager in the production variant.
• dumb-init is used as the PID 1 process for proper signal handling.

Getting Started

To start s3proxy with a local filesystem backend and anonymous access:

docker run -d --name s3proxy -p 8080:8080 \
  -e S3PROXY_AUTHORIZATION=none \
  cgr.dev/ORGANIZATION/s3proxy:latest

Once the container is running, you can verify it is working by listing buckets:

curl http://localhost:8080/

To create a bucket and upload an object using the AWS CLI:

aws --endpoint-url http://localhost:8080 s3 mb s3://my-bucket
aws --endpoint-url http://localhost:8080 s3 cp /path/to/file s3://my-bucket/

Configuration

For configuration options and environment variables, refer to the upstream S3Proxy documentation.

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.
