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.
