A Cluster API Provider implementation using docker containers as the infra provider. Cluster API locally for a change!

Cluster API Provider Docker

Manager Container Image

A sample is built and hosted at gcr.io/kubernetes1-226021/manager:latest

External Dependencies

• go, 1.12+
• kubectl
• docker

Building Go binaries

Building Go binaries requires go 1.12+ for go module support.

# required if `cluster-api-provider-docker` was cloned into $GOPATH
export GO111MODULE=on
# build the binaries into ${PWD}/bin
./script/build-binaries.sh

Building the image

Using Gcloud

Make sure gcloud is authenticated and configured.

You also need to set up a google cloud project.

Run: ./scripts/publish-manager.sh

Using Docker

Alternatively, to publish the manager container image to your pre-existing custom container registry, run: REGISTRY=<MY_REGISTRY> ./scripts/publish-manager.sh

NOTE: You should have run docker login to login to your custom container registry.

Trying CAPD

Tested on: Linux, works ok on OS X sometimes

Make sure you have kubectl.

1. Install capdctl:

   go install ./cmd/capdctl

2. Start a management kind cluster

   capdctl setup

3. Set up your kubectl

   export KUBECONFIG="${HOME}/.kube/kind-config-management"

Create a worker cluster

kubectl apply -f examples/simple-cluster.yaml

Interact with a worker cluster

The kubeconfig is on the management cluster in secrets. Grab it and write it to a file:

kubectl get secrets -o jsonpath='{.data.value}' my-cluster-kubeconfig | base64 --decode > ~/.kube/kind-config-my-cluster

Look at the pods in your new worker cluster: kubectl get po --all-namespaces --kubeconfig ~/.kube/kind-config-my-cluster
