kubetest2

Kubetest2 is a framework for deploying Kubernetes clusters and running end-to-end tests against them.

It is intended to be the next significant iteration of kubetest

Concepts

kubetest2 is effectively split into three independent executables:

• kubetest2: discovers and invokes deployers and testers in PATH
• kubetest2-DEPLOYER: manages the lifecycle of a Kubernetes cluster
• kubetest2-tester-TESTER: tests a Kubernetes cluster

The intent behind this design is:

• minimize coupling between deployers and testers
• encourage implementation of new deployers and testers out-of-tree
• keep dependencies / surface area of kubetest2 small

We provide reference implementations but all all new implementations should be external implementations

Installation

To install kubetest2 and all reference deployers and testers: go install sigs.k8s.io/kubetest2/...@latest

To install a specific deployer: go install sigs.k8s.io/kubetest2/kubetest2-DEPLOYER@latest (DEPLOYER can be gce, gke, etc.)

To install a sepcific tester: go install sigs.k8s.io/kubetest2/kubetest2-tester-TESTER@latest (TESTER can be ginkgo, exec, etc.)

Usage

General usage is of the form:

kubetest2 <deployer> [Flags] [DeployerFlags] -- [TesterArgs]

Example: list all flags for the noop deployer and ginkgo tester

kubetest2 noop --test=ginkgo --help

Example: deploy a cluster using a local checkout of kubernetes/kubernetes, run Conformance tests

kubetest2 gce -v 2 \
  --repo-root $KK_REPO_ROOT \
  --gcp-project $YOUR_GCP_PROJECT \
  --legacy-mode \
  --build \
  --up \
  --down \
  --test=ginkgo \
  -- \
  --focus-regex='\[Conformance\]'

Reference Implementations

See individual READMEs for more information

Deployers

• kubetest2-gce - use scripts in kubernetes/cloud-provider-gcp or kubernetes/kubernetes
• kubetest2-gke - use gcloud containers
• kubetest2-kind - use kind
• kubetest2-noop - do nothing (to use a pre-existing cluster)

Testers

• kubetest2-tester-clusterloader2 - use clusterloader2
• kubetest2-tester-exec - exec a given command with the given args / flags
• kubetest2-tester-ginkgo - runs e2e tests from kubernetes/kubernetes
• kubetest2-tester-node - runs node e2e tests from kubernetes/kubernetes

External Implementations

Deployers

• kubetest2-aks
• kubetest2-kops
• kubetest2-tf
• kubetest2-ec2

Testers

• kubetest2-tester-kops

Support

This project is currently unversioned and unreleased. We make a best-effort attempt to enforce the following:

• kubetest2 and its reference implementations must work with the in-development version of kubernetes and all currently supported kubernetes releases
  • e.g. no generics until older supported kubernetes version supports generics
  • e.g. ginkgo tester must work with both ginkgo v1 and ginkgo v2
• changes to the following testers must not break jobs in the kubernetes project
  • kubetest2-tester-exec
  • kubetest2-tester-ginkgo
