## README

## 介绍

主要测试openEuler/ubuntu + containerd/wasmEdge/iSulad + fleet/k8s/k3s + nebula/cilium环境。
目前专注于openEuler 24.03环境

**注意**： 本项目主要面向开发、测试和演示场景，如果需要生产部署请联系我们。

## 软件架构

- 操作系统
  - [openEuler 24.03](https://www.openeuler.org/zh/download/?version=openEuler%2024.03%20LTS)
- 容器引擎
  - [containerd](https://containerd.io/)
- 资源编排(替换k8s/k3s)
  - [fleet](https://gitee.com/iscas-system/fleet-core)
- 网络插件(类似flannel和cilium)
  - [nebula](https://gitee.com/iscas-system/plugins)
- 存储插件：
  - [gfs2](https://docs.redhat.com/zh_hans/documentation/red_hat_enterprise_linux/8/html-single/configuring_gfs2_file_systems/index)

## 推荐环境

### 数据中心

1. 单点：Ubuntu 24.03
```
kubeinst init-osenv
kubeinst init-runtime containerd
kubeinst init-compute kubernetes
kubeinst init-network cilium
kubeinst init-network kubeovn
```

### 边缘智能

1. 开源：OpenEuler>=24.03

```
kubeinst init-osenv
kubeinst init-runtime containerd
kubeinst init-compute fleet
kubeinst init-network nebula
```

### 已经测试

-  OpenEuler 24.03
   - runc/containerd + fleet + nebula


注：如果是kubernetes，安装nebula会报文件冲突，以下是解决方案

```
# 下载 nebula-cni 的 rpm 包  
wget <nebula-cni-rpm-包的URL>  
  
# 使用 rpm 命令强制安装，替换冲突的文件  
sudo rpm -Uvh --force --replacefiles <下载的nebula-cni-rpm包名>

```

### token管理

1.   创建token


```
kubectl apply -f https://gitee.com/iscas-system/client/raw/master/token.yaml
```

2.   获取token

```
kubectl -n kube-system describe secret $(kubectl -n kube-system get secret | grep iscas-client | awk '{print $1}') | grep "token:" | awk -F":" '{print$2}' | sed 's/ //g'
```

### 多网卡管理

1. 部署 flannel： kubeinst init-network flannel

2. 部署多网卡组件 multus：kubeinst init-network multus

3. 添加第二块网卡配置文件：

``` bash
cat <<EOF | kubectl create -f -
apiVersion: "k8s.cni.cncf.io/v1"
kind: NetworkAttachmentDefinition
metadata:
  name: macvlan-conf-1
  namespace: testns1
spec:
  config: '{
            "cniVersion": "0.3.0",
            "type": "macvlan",
            "master": "eth1",  //换成你的网卡名
            "mode": "bridge",
            "ipam": {
                "type": "host-local",
                "ranges": [
                    [ {
                         "subnet": "12.10.0.0/16",       //换成你的IP段
                         "rangeStart": "12.10.1.20",     //换成你的IP段
                         "rangeEnd": "12.10.3.50"        //换成你的IP段
                    } ]
                ]
            }
        }'
EOF
cat <<EOF | kubectl create -f -
apiVersion: v1
kind: Pod
metadata:
  name: pod-case-02
  annotations:
    k8s.v1.cni.cncf.io/networks: testns1/macvlan-conf-1
spec:
  containers:
  - name: pod-case-02
    image: g-ubjg5602-docker.pkg.coding.net/iscas-system/containers/busybox:latest
    command: ["sleep", "3600"]
EOF
```


```
kubectl exec -it pod-case-02 -- /bin/sh
```
