Fast development iteration of a Kubernetes API using Kubebuilder with Skaffold.
Trying Skaffold hot reload feature developping Kubernetes Controllers.
Getting started with the projects assumes you have:
- Kubernetes Cluster
- Kubebuilder
- Kustomize
- Skaffold
- Docker
If everything (GOPATH, dep, Skaffold, Docker local registry) is set up right, run:
$ skaffold dev
This should compile the code, create the docker image and deploy it to the kubernetes cluster.
Making changes to the code within pkg/controller/sloop/sloop_controller.go trigger skaffold to automatically detect the change and build a new image and deploy it to the cluster.
skaffold prints containers logs, you can get the logs by running:
$ kubectl -n sloops-system logs -f -c manager sloops-controller-manager-0
You can manually trigger changes to skaffold, using:
$ skaffold dev --trigger manual
To deploy Kubernetes cluster, I used kubeadm-dind-cluster, helpers can be found under the cluster directory.
