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 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:

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.
