Chainguard Container for pulumi

Minimal Pulumi Image

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/pulumi:latest

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

Usage

Kubernetes Pod Example

In this directory, check the examples/ folder. You should find an example app for the following support Pulumi languages/runtimes:

• dotnet
• go
• java
• nodejs
• python
• yaml

This will show an example of using Pulumi SDKs to create an Nginx pod in a kind cluster.

Try running these commands from this directory in the repo.

Set the desired language to the env var TEST_LANG:

export TEST_LANG=go

Start a kind cluster:

kind create cluster

Extract the kubeconfig, and modify it to use an internal IP:

KIND_IP="$(docker ps | grep 'control-plane' | awk '{print $1}' | xargs docker inspect | jq -r '.[0].NetworkSettings.Networks["kind"].IPAddress')"

mkdir .kube
kind get kubeconfig | yq '.clusters[].cluster.server = "https://'${KIND_IP}':6443"' \
    > ".kube/config"

Create a temporary Pulumi home directory, and do a local login:

mkdir .pulumi
docker run --rm --network kind \
    -w "/work/examples/smoketest-${TEST_LANG}" \
    -v "${PWD}:/work" \
    -e PULUMI_HOME=/work/.pulumi \
    cgr.dev/chainguard/pulumi:latest \
    login file://.

Decide a unique stack name:

export STACK_NAME="${TEST_LANG}-$(date +%s)"

Next, init a stack (for you decided language):

docker run --rm --network kind \
    -w "/work/examples/smoketest-${TEST_LANG}" \
    -v "${PWD}:/work" \
    -e PULUMI_HOME=/work/.pulumi \
    -e PULUMI_CONFIG_PASSPHRASE="${STACK_NAME}" \
    cgr.dev/chainguard/pulumi:latest \
    stack init --non-interactive --stack ${STACK_NAME}

Note: for some runtimes, you may need to install language-specific dependencies ahead of time. Here is an example of preinstalling Node.js dpendencies using npm install:

docker run --rm -w /work/smoketest-${lang} \
    -v "${TMPDIR}:/work" \
    --entrypoint npm \
    cgr.dev/chainguard/pulumi:latest \
    install

Finally, create the stack:

docker run --rm --network kind \
    -w "/work/examples/smoketest-${TEST_LANG}" \
    -v "${PWD}:/work" \
    -e PULUMI_HOME=/work/.pulumi \
    -e PULUMI_CONFIG_PASSPHRASE="${STACK_NAME}" \
    -e KUBECONFIG=/work/.kube/config \
    cgr.dev/chainguard/pulumi:latest \
    up --yes --config name=${STACK_NAME}

You should notice a pod in the default namespace has been created:

$ kubectl get pods
NAME            READY   STATUS    RESTARTS   AGE
go-1683319492   1/1     Running   0          24s

To teardown the stack, run the following:

docker run --rm --network kind \
    -w "/work/examples/smoketest-${TEST_LANG}" \
    -v "${PWD}:/work" \
    -e PULUMI_HOME=/work/.pulumi \
    -e PULUMI_CONFIG_PASSPHRASE="${STACK_NAME}" \
    -e KUBECONFIG=/work/.kube/config \
    cgr.dev/chainguard/pulumi:latest \
    destroy --yes

Now check for pods, there should not be any:

$ kubectl get pods
No resources found in default namespace.

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.
