Installing Spinnnaker

In this lab, you will use Helm to install Spinnaker from the Charts repository. Helm is a package manager that makes it easy to configure and deploy Kubernetes applications. Once you have Spinnaker installed, you'll be able to set up your CI/CD pipleline.

Installing Helm

  1. Download and install the helm binary
wget https://storage.googleapis.com/kubernetes-helm/helm-v2.5.0-linux-amd64.tar.gz
  1. Unzip the file to your local system:
tar zxfv helm-v2.5.0-linux-amd64.tar.gz
cp linux-amd64/helm .
  1. Initialize Helm. This ensures that the server side of Helm (Tiller) is properly installed in your cluster.
./helm init
./helm update
  1. Ensure Helm is properly installed by running the following command. You should see versions appear for both the server and the client of v2.5.0:
./helm version
Client: &version.Version{SemVer:"v2.5.0", GitCommit:"012cb0ac1a1b2f888144ef5a67b8dab6c2d45be6", GitTreeState:"clean"}Server: &version.Version{SemVer:"v2.5.0", GitCommit:"012cb0ac1a1b2f888144ef5a67b8dab6c2d45be6", GitTreeState:"clean"}

Configure Spinnaker

  1. Create a bucket for spinnaker to store its pipeline configuration:
export PROJECT=$(gcloud info --format='value(config.project)')
export BUCKET=$PROJECT-spinnaker-config
gsutil mb -c regional -l us-central1 gs://$BUCKET
  1. Create your configuration file by pasting the following commands into your Cloud Shell:
export SA_JSON=`cat spinnaker-sa.json`
cat > spinnaker-config.yaml <<EOF
storageBucket: $BUCKET
gcs:
  enabled: true
  project: $PROJECT
  jsonKey: '$SA_JSON'

# Disable minio the default
minio:
  enabled: false

# Configure your Docker registries here
accounts:
- name: gcr
  address: https://gcr.io
  username: _json_key
  password: '$SA_JSON'
  email: [email protected]
EOF

Deploying the Spinnaker Chart

  1. Use the Helm CLI to deploy the chart with your configuration set.

Note: This command typically takes 5-10 minutes to complete.

./helm install -n cd stable/spinnaker -f spinnaker-config.yaml --timeout 600 --version 0.3.1
  1. Once that command completes, run the following command to setup port forwarding to the Spinnaker U from the Cloud Shell
export DECK_POD=$(kubectl get pods --namespace default -l "component=deck" -o jsonpath="{.items[0].metadata.name}")
kubectl port-forward --namespace default $DECK_POD 8080:9000 >> /dev/null &

To get to the Spinnaker user interface, click on the Web Preview button in cloud shell, then click “Preview on port 8080”

You should now see the following screen: followed by the Spinnaker UI:

What's Next

Now that you have Spinnaker installed on your GKE cluster, it's time to create container images to deploy in the pipeline we'll be creating later.
