Getting Started on Google Compute Engine

In the following example we will create a kubernetes cluster on a GCEProvider. All the GCEProvider needs besides a writable Git Repository is a billable Google Cloud Project and a Google Service Account with sufficient permissions.

Initialize A Git Repository

Copy the files orbiter.yml and boom.yml to the root of a new git Repository.

Configure your local environment

# Install the latest orbctl
curl -s https://api.github.com/repos/caos/orbos/releases/latest | grep "browser_download_url.*orbctl-$(uname)-$(uname -m)" | cut -d '"' -f 4 | sudo wget -i - -O /usr/local/bin/orbctl
sudo chmod +x /usr/local/bin/orbctl
sudo chown $(id -u):$(id -g) /usr/local/bin/orbctl

# Create an orb file at ${HOME}/.orb/config
orbctl configure --repourl [email protected]:me/my-orb.git --masterkey "$(openssl rand -base64 21)"

Configure a billable Google Cloud Platform project of your choice

MY_GCE_PROJECT="$(gcloud config get-value project)"
ORBOS_SERVICE_ACCOUNT_NAME=orbiter-system
ORBOS_SERVICE_ACCOUNT=${ORBOS_SERVICE_ACCOUNT_NAME}@${MY_GCE_PROJECT}.iam.gserviceaccount.com

# Create a service account for the ORBITER user
gcloud iam service-accounts create ${ORBOS_SERVICE_ACCOUNT_NAME} \
    --description="${ORBOS_SERVICE_ACCOUNT_NAME}" \
    --display-name="${ORBOS_SERVICE_ACCOUNT_NAME}"

# Assign the service account the roles `Compute Admin`, `IAP-secured Tunnel User` and `Service Usage Admin`
gcloud projects add-iam-policy-binding ${MY_GCE_PROJECT} \
    --member=serviceAccount:${ORBOS_SERVICE_ACCOUNT} \
    --role=roles/compute.admin
gcloud projects add-iam-policy-binding ${MY_GCE_PROJECT} \
    --member=serviceAccount:${ORBOS_SERVICE_ACCOUNT} \
    --role=roles/iap.tunnelResourceAccessor
gcloud projects add-iam-policy-binding ${MY_GCE_PROJECT} \
    --member=serviceAccount:${ORBOS_SERVICE_ACCOUNT} \
    --role=roles/serviceusage.serviceUsageAdmin
gcloud projects add-iam-policy-binding ${MY_GCE_PROJECT} \
    --member=serviceAccount:${ORBOS_SERVICE_ACCOUNT} \
    --role=roles/iam.serviceAccountUser


# Create a JSON key for the service account
gcloud iam service-accounts keys create /tmp/key.json \
  --iam-account ${ORBOS_SERVICE_ACCOUNT}

# Encrypt and write the created JSON key to the orbiter.yml
orbctl writesecret orbiter.gce.jsonkey --file /tmp/key.json
rm -f /tmp/key.json

Bootstrap your Kubernetes cluster on GCE

orbctl takeoff

As soon as the Orbiter has deployed itself to the cluster, you can decrypt the generated admin kubeconfig

mkdir -p ~/.kube
orbctl readsecret orbiter.k8s.kubeconfig > ~/.kube/config

Wait for grafana to become running

kubectl --namespace caos-system get po -w

Open your browser at http://localhost:8080 to show your new clusters dashboards. Default username and password are both admin

kubectl --namespace caos-system port-forward svc/grafana 8080:80

Delete everything created by Orbiter

# Remove all GCE compute resources
orbctl destroy

# Unassign all service account roles
gcloud projects remove-iam-policy-binding ${MY_GCE_PROJECT} \
    --member=serviceAccount:${ORBOS_SERVICE_ACCOUNT} \
    --role=roles/compute.admin
gcloud projects remove-iam-policy-binding ${MY_GCE_PROJECT} \
    --member=serviceAccount:${ORBOS_SERVICE_ACCOUNT} \
    --role=roles/iap.tunnelResourceAccessor
gcloud projects remove-iam-policy-binding ${MY_GCE_PROJECT} \
    --member=serviceAccount:${ORBOS_SERVICE_ACCOUNT} \
    --role=roles/serviceusage.serviceUsageAdmin

# Remove service account
gcloud iam service-accounts delete --quiet ${ORBOS_SERVICE_ACCOUNT}
