Chainguard Container for deno

Minimal container image for running Deno apps

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/deno:latest

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

The image specifies a default non-root deno user (UID 65532), and a working directory at /app, owned by that deno user, and accessible to all users.

Usage Example

Navigate to the example/ directory:

cd example/

The Dockerfile is based on Deno's webserver tutorial, but packages it up into a Chainguard deno image.

Build the application on the deno base image.

docker build \
  --tag deno-docker \
  .

Then you can run the image:

docker run \
  --rm -it \
  -p 8080:8080 \
  deno-docker

...and test to see that it works:

$ curl localhost:8080
Your user-agent is:

curl/7.84.0%

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.
