# 关于K8S集群一致性认证
CNCF 一致性认证项目(https://github.com/cncf/k8s-conformance) 可以很方便帮助k8s搭建者和用户确认集群各项功能符合预期既符合k8s设计标准。
# kubeasz 通过一致性测试
自kubeasz 3.0.0 版本k8s v1.20.2开始正式通过cncf一致性认证成为cncf 官方认证安装工具后续k8s主要版本发布或者kubeasz有大版本更新会优先确保通过集群一致性认证。
- v1.29 [进行中]()
- v1.28 [已认证](https://github.com/cncf/k8s-conformance/tree/master/v1.28/kubeasz)
- v1.27 [已认证](https://github.com/cncf/k8s-conformance/tree/master/v1.27/kubeasz)
- v1.26 [已认证](https://github.com/cncf/k8s-conformance/tree/master/v1.26/kubeasz)
- v1.25 [已认证](https://github.com/cncf/k8s-conformance/tree/master/v1.25/kubeasz)
- v1.24 [已认证](https://github.com/cncf/k8s-conformance/tree/master/v1.24/kubeasz)
- v1.23 [已认证](https://github.com/cncf/k8s-conformance/tree/master/v1.23/kubeasz)
- v1.22 [已认证](https://github.com/cncf/k8s-conformance/tree/master/v1.22/kubeasz)
- v1.21 [已认证](https://github.com/cncf/k8s-conformance/tree/master/v1.21/kubeasz)
- v1.20 [已认证](https://github.com/cncf/k8s-conformance/tree/master/v1.20/kubeasz)
## Conformance Test
按照测试文档,注意以下几点:
1.解决qiang的问题可以临时去国外公有云创建集群然后运行测试项目。
2.集群要保障资源建议3个节点
3.网络组件选择calico其他组件可能有bug导致特定测试项失败
# 附:测试流程
## 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](https://github.com/easzlab/kubeasz/blob/master/docs/setup/00-planning_and_overall_intro.md)
## Install the cluster
(1) Download 'kubeasz' code, the binaries and offline images
```
export release=3.2.0
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}
dk ezctl add-node default ${worker1_ip}
ssh-copy-id ${worker2_ip}
dk ezctl add-node default ${worker2_ip}
```
## Run Conformance Test
The standard tool for running these tests is
[Sonobuoy](https://github.com/heptio/sonobuoy). Sonobuoy is
regularly built and kept up to date to execute against all
currently supported versions of kubernetes.
Download a [binary release](https://github.com/heptio/sonobuoy/releases) 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
```
