Conformance tests for kubeasz kubernetes cluster

Node Provisioning

Provision 3 nodes for your cluster (OS: Ubuntu 20.04)

1 master node (4c16g)

2 worker node (4c16g)

for a High-Availability Kubernetes Cluster, read more

Install the cluster

(1) Download 'kubeasz' code, the binaries and offline images

export release=3.6.0
curl -C- -fLO --retry 3 https://github.com/easzlab/kubeasz/releases/download/${release}/ezdown
chmod +x ./ezdown
./ezdown -D -m standard

(2) install an all-in-one cluster

./ezdown -S
source ~/.bashrc
dk ezctl start-aio

(3) Add two worker nodes

ssh-copy-id ${worker1_ip}
ssh ${worker1_ip} ln -s /usr/bin/python3 /usr/bin/python
dk ezctl add-node default ${worker1_ip}

ssh-copy-id ${worker2_ip}
ssh ${worker2_ip} ln -s /usr/bin/python3 /usr/bin/python
dk ezctl add-node default ${worker2_ip}

Run Conformance Test

The standard tool for running these tests is Sonobuoy. Sonobuoy is regularly built and kept up to date to execute against all currently supported versions of kubernetes.

Download a binary release of the CLI

Deploy a Sonobuoy pod to your cluster with:

$ sonobuoy run --plugin-env=e2e.E2E_EXTRA_ARGS="--ginkgo.v" --mode=certified-conformance

NOTE: You can run the command synchronously by adding the flag --wait but be aware that running the Conformance tests can take an hour or more.

View actively running pods:

$ sonobuoy status

To inspect the logs:

$ sonobuoy logs

Once sonobuoy status shows the run as completed, copy the output directory from the main Sonobuoy pod to a local directory:

$ outfile=$(sonobuoy retrieve)

This copies a single .tar.gz snapshot from the Sonobuoy pod into your local . directory. Extract the contents into ./results with:

mkdir ./results; tar xzf $outfile -C ./results

NOTE: The two files required for submission are located in the tarball under plugins/e2e/results/{e2e.log,junit.xml}.

To clean up Kubernetes objects created by Sonobuoy, run:

sonobuoy delete
