spin-operator VS kyma

With our Spin application completed, we can now deploy it to Kubernetes by configuring the cluster with SpinKube. SpinKube is an open source project that enables running Spin applications on Kubernetes alongside containers. The project consists of 4 sub-projects, the Spin Operator, the spin kube plugin, the runtime class manager, and the Spin containerd shim. The latter is what contains the Spin runtime and executes the Spin applications on your nodes. The v0.16.0 release of the shim added support for the MQTT trigger, enabling us to run our application on SpinKube! You can use one of SpinKube’s installation guides to install SpinKube on your distribution of Kubernetes.

The team behind SpinKube provides some sample apps in their spin operator repository that you can use to test the setup and deploy a simple hello world app. Make sure that you reference the raw file from GitHub via:

# Install SpinKube CRDs kubectl apply -f https://github.com/spinkube/spin-operator/releases/download/v0.1.0/spin-operator.crds.yaml # Install a RuntimeClass for wasmtime-spin-v2 kubectl apply -f https://github.com/spinkube/spin-operator/releases/download/v0.1.0/spin-operator.runtime-class.yaml # Install the containerd-spin-shim SpinAppExecutor kubectl apply -f https://github.com/spinkube/spin-operator/releases/download/v0.1.0/spin-operator.shim-executor.yaml # Install Spin Operator with Helm helm install spin-operator \ --namespace spin-operator \ --create-namespace \ --version 0.1.0 \ --wait \ oci://ghcr.io/spinkube/charts/spin-operator

Spin Operator - facilitating the orchestration of Wasm workloads in k8s

Although I had the project on my radar, I never took a closer look at it. However, now it was the time to give it a spin ... or try. All I needed was a Kubernetes environment. As I am working in the SAP space the choice of Kubernetes is kind of predefined, namely Kyma in its managed version on the SAP Business Technology Platform.

News from the SAP side: the clear focus is here SAP Business Technology Platform especially Kyma

I could only find https://github.com/kyma-project/kyma as something close to being real-world. But my google fu is failing here. Any help would be appreciated :)

I am using Kyma as opinionated stack on top of Kubernetes (to be precise on a Gardener cluster) for this exercise. The setup should be similar for vanilla stacks, but the API gateway must be adjusted accordingly depending on what you use.

So you can install Kyma 1.x without own domain, but you have no access to the Kyma console UI. An issue is open for this (https://github.com/kyma-project/kyma/issues/11924) and according to the Kyma slack channel the situation will improve with the upcoming release of Kyma 2.x, but until then you must provide an own domain to get access to the Kyma console UI. From my point of view this lifts the entry barrier of trying out open-source Kyma, but currently this is the way.
