The runtime-class-manager is the spiritual successor to the kwasm-operator. kwasm has been developed as an experimental, simple way to install Wasm runtimes. This experiment has been relatively successful, as more and more users utilized it to fiddle around with Wasm on Kubernetes. However, the kwasm-operator has some limitations that make it difficult to use in production. The runtime-class-manager is an attempt to address these limitations to make it a reliable and secure way to deploy arbitrary containerd shims.
The implementation of runtime-class-manager follows this community proposal.
The name should be treated as a working title and is hopefully subject to change.
For the 1.0 release of runtime-class-manager, we consider three milestones:
Build and push your image to the location specified by IMG
:
make docker-build docker-push IMG=<some-registry>/runtime-class-manager:tag
NOTE: This image ought to be published in the personal registry you specified. And it is required to have access to pull the image from the working environment. Make sure you have the proper permission to the registry if the above commands don’t work.
Install the CRDs into the cluster:
make install
Deploy the Manager to the cluster with the image specified by IMG
:
make deploy IMG=<some-registry>/runtime-class-manager:tag
NOTE: If you encounter RBAC errors, you may need to grant yourself cluster-admin privileges or be logged in as admin.
Create instances of your solution You can apply the samples (examples) from the config/sample:
kubectl apply -k config/samples/
NOTE: Ensure that the samples has default values to test it out.
Delete the instances (CRs) from the cluster:
kubectl delete -k config/samples/
Delete the APIs(CRDs) from the cluster:
make uninstall
UnDeploy the controller from the cluster:
make undeploy
