Development and Testing Environment Providers

All following providers allow a common workflow:

  • make cluster-up to create the environment
  • make cluster-down to stop the environment
  • make cluster-build to build
  • make cluster-deploy to (re)deploy the code (no provider support needed)
  • make cluster-sync to build and (re)deploy the code
  • make functests to run the functional tests against KubeVirt
  • cluster-up/kubectl.sh to talk to the k8s installation

It is recommended to export the KUBEVIRT_PROVIDER variable as part of your .bashrc file.

Dockerized k8s/ocp clusters

Allows provisioning k8s cluster based on kubeadm. Supports an arbitrary amount of nodes.

Requires:

  • A working go installation
  • Nested virtualization enabled
  • A running docker daemon

Usage:

export KUBEVIRT_PROVIDER=k8s-1.13.3 # choose this provider
export KUBEVIRT_NUM_NODES=3 # master + two nodes
make cluster-up

Local

Allows provisioning a single-master k8s cluster based on latest upstream k8s code.

Requires:

  • A working go installation
  • A running docker daemon

Usage:

export KUBEVIRT_PROVIDER=local # choose this provider
make cluster-up

External

Uses an existing (external) Kubernetes cluster.

Requires:

  • A working Kubernetes cluster with properly configured worker nodes.
  • A running docker daemon

Usage:

export KUBEVIRT_PROVIDER=external # choose this provider
make cluster-up

New Providers

First add your provider in the kubevirtci repository. After this provider is merged, update our copy of this repository with the following command:

make bump-kubevirtci
