Install on Google Kubernetes Engine

The simplest way to provision a cluster on Google Cloud Platform is via Google Kubernetes Engine.

As a prerequisit, please install and authenticate the gcloud command line tool. Instructions can be found here.

Step 1: Create a GKE Cluster

There are a few different ways to create a GKE Cluster. You can either create one through only gcloud, use the web interface, or with Terraform.

Option A - gcloud command line

To begin, choose a Google Cloud project

export PROJECT_ID=hello-kalm

Note: If you don't have an existing Google Cloud project, you can create one with:

export PROJECT_ID=hello-kalm
gcloud projects create $PROJECT_ID

Make sure billing is enabled.

You need to enable Kubernetes Engine API as well:

gcloud services enable

Next, provision a cluster with 4 nodes

export M_TYPE=n1-standard-2 && \
export ZONE=us-west2-a && \
gcloud container clusters create $CLUSTER_NAME \
--cluster-version latest \
--machine-type=$M_TYPE \
--num-nodes 4 \
--zone $ZONE \
--project $PROJECT_ID

The creation of the cluster will take a few minutes. Once complete, configure kubectl to use the new cluster:

gcloud container clusters get-credentials $CLUSTER_NAME \
--zone $ZONE \
--project $PROJECT_ID

Verify the cluster is properly setup and accessible.

kubectl cluster-info

Option B - Terraform

If you are more familiar with Terraform, you can provision a demo cluster with the following steps.

First, install Terraform.

Give Terraform access to the Application Default Credentials (ADC).

gcloud auth application-default login

Clone the repository below.

git clone
cd tf-scripts/gke

Open 'terraform.tfvars', and specify the ID of the Google Cloud project you would like to install to.

# terraform.tfvars
project_id = "REPLACE_ME"
region = "us-west2"

Install the cluster with the following commands.

terraform init
terraform apply

Type yes to confirm the installation.

After 5-10 minutes, the cluster should be created. Once complete, retrieve the name of the newly created cluster.

terraform output

Configure kubectl to use the new cluster.

gcloud container clusters get-credentials NAME_OF_YOUR_CLUSTER --zone ZONE_OF_CLUSTER

Verify the cluster is properly setup and accessible.

kubectl cluster-info

Step 2: Install Kalm

Once the cluster is setup, install Kalm with the following command.

curl -sL | bash

To enable localhost access, open a port via:

kubectl port-forward -n kalm-system \
$(kubectl get pod -n kalm-system \
-l app=kalm \
-ojsonpath="{.items[0]}") \

Now open http://localhost:3010/

Clean Up

Delete the cluster to avoid resource charges.

If you created the cluster with Terraform:

terraform destroy

Next Step

You've now setup Kalm on a GKE cluster. To get a sense of how Kalm works, see the Hello Kalm tutorial.
