# 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
|
||
|
||
Cheers!
|
||
|
||
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。
|
||
|
||
- v1.23 [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
|
||
docker exec -it kubeasz ezctl start-aio
|
||
```
|
||
|
||
(3) Add two worker nodes
|
||
|
||
```
|
||
ssh-copy-id ${worker1_ip}
|
||
ssh ${worker1_ip} ln -s /usr/bin/python3 /usr/bin/python
|
||
docker exec -it kubeasz ezctl add-node default ${worker1_ip}
|
||
ssh-copy-id ${worker2_ip}
|
||
ssh ${worker2_ip} ln -s /usr/bin/python3 /usr/bin/python
|
||
docker exec -it kubeasz 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, or build it yourself by running:
|
||
|
||
```
|
||
$ go get -u -v github.com/heptio/sonobuoy
|
||
```
|
||
|
||
Deploy a Sonobuoy pod to your cluster with:
|
||
|
||
```
|
||
$ sonobuoy run --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
|
||
```
