Kyma 2.0

Deploying Kyma

Installing open source Kyma on a local computer for learning, evaluation, development, and test is easy.

Open source Rancher Desktop makes this even easier as it provides a Kubernetes cluster (k3d) without any (cluster) installation or configuration requirements.

About Minikube and Docker

For many years, minikube has been the standard sandbox environment to run a Kubernetes locally, i.e. on a developer computer running Linux, macOS, or Windows. Minikube uses a local hypervisor and a virtual machine, which adds overhead (although configurable).

More recently, lightweight alternatives like k3d and kind (kubernetes-in-docker) have grown in popularity.

For many years, Docker Desktop has been the standard environment to build, share, and run Docker containers. As of August 2021, a subscription is required.

About Rancher Desktop

Recently, SUSE release Rancher Desktop. It’s an open source app for desktop Kubernetes and container management on Mac, Windows and Linux.

• Rancher Desktop 1.0.0 Has Arrived

For the docs, see

• rancherdesktop.io

Preparation

The prerequisites for a Kyma deployment are a local Kubernetes cluster and the Kyma CLI.

Install Rancher

To download, go to

• rancherdesktop.io

The installation takes no parameters. Depending on the operating system a reboot may be required.

Install Kyma CLI

You can install the Kyma CLI directly from GitHub or use a package manager

• Homebrew for macOS
• Chocolatey for Windows

Installing the CLI takes a few seconds.

# macOS
brew install kyma-cli

# Windows
choco install kyma-cli

Deploy

Kubernetes Settings

Change the Kubernetes version to a supported version, set the runtime to dockerd, and allocate enough resources.

Minimal resource requirements are not documented but you can take a hint from the SAP BTP Kyma runtime minimal virtual machine configuration: 8 vCPU and 32GB memory.

For the supported Kubernetes version, see

• Install Kyma | Project Kyma

Deploy Kyma

Now that we have a (local) Kuberneter cluster, we can deploy the Kyma runtime. For the (limited) options, see

• Install Kyma | Project Kyma

For the online help, run

kyma deploy -h

With limited resources, i.e. when using a lap- or desktop, you can include the evaluation parameter.

kyma deploy -p evaluation

Kyma deploys to the current context. To set the context, you can use the kubectl command.

• kubectl Cheat Sheet | Kubernetes

For information about kubectl, see Tools below.

For more information about the components, see

• Main area | Kyma docs

Tools

Kubectl

The kubectl CLI is not required to deploy Kyma but will be needed to access the cluster. See for example

• Accessing Kyma Kubernetes Clusters Using Command Line – Introduction to Kubectl by Cameron Swift

As with the Kyma CLI, you can install kubectl using a package manager.

# macOS
brew install kubernetes-cli

# Windows
choco install kubernetes-cli
