Kubebuilder v2 Seldon Operator

Development

We assume:

• Go 1.13
• Kubebuilder 2.3.0

Issues

• Generated CRD is not structural: https://github.com/kubernetes-sigs/controller-tools/issues/304 There is a PR for this: https://github.com/kubernetes-sigs/controller-tools/pull/312

Prerequisites

For running locally kind, kustomize and kubebuilder should be installed.

Testing

If you installed kubebuilder outside of /usr/local/kubebuilder then you will need to set the env var KUBEBUILDER_ASSETS for example:

export KUBEBUILDER_ASSETS=/home/clive/tools/kubebuilder_2.3.0_linux_amd64/bin

Start a kind cluster

kind create cluster
export KUBECONFIG="$(kind get kubeconfig-path --name="kind")"

Install CRD and cert-manager

make install
make install-cert-manager

Build image

make docker-build

Standard Deploy

make deploy

Local Development Deploy

Deploy with webhook config set to point to host

make deploy-local

When running update tls certificates locally

make tls-extract

Now delete the cluster Deployment as we will run the manager locally:

kubectl delete deployment -n seldon-system seldon-controller-manager

Now we can run locally:

make run

You should now be able to create SeldonDeployments and Webhook calls will hit the local running manager. The same applies if you debug from GoLand. Though for GoLand you will need to export the KUBECONFIG to the debug configuration.

You should delete the Operator running in the cluster at this point.

Build Helm Chart

Use the Makefile in the ./helm directory. Ensure you have pyyaml in your python environment.
