Ubuntu云原生环境安装，docker+k8s+kubeedge（亲测好用）

2023-11-17

docker安装步骤（Linux）

一、移除以前docker相关包

sudo apt-get autoremove docker docker-ce docker-engine  docker.io  containerd runc

二、设置存储库

1、更新软件包索引并安装软件包，以允许通过 HTTPS 使用存储库

sudo apt-get update

sudo apt-get install \
    ca-certificates \
    curl \
    gnupg \
    lsb-release

2、添加 Docker 的官方 GPG 密钥

sudo curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg

3、使用以下命令设置稳定存储库

echo \
  "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/ubuntu \
  $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

三、安装docker

 sudo apt-get update
 #要安装特定版本的 Docker 引擎，请在存储库中列出可用版本，然后选择并安装
 sudo apt-cache madison docker-ce

在这里插入图片描述

安装特定版本

sudo apt-get install docker-ce=<VERSION_STRING> docker-ce-cli=<VERSION_STRING> containerd.io docker-compose-plugin

四、配置加速

这里额外添加了docker的生产环境核心配置cgroup

sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
  "registry-mirrors": ["https://82m9ar63.mirror.aliyuncs.com"],
  "exec-opts": ["native.cgroupdriver=systemd"],
  "log-driver": "json-file",
  "log-opts": {
    "max-size": "100m"
  },
  "storage-driver": "overlay2"
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker

五、验证是否安装成功

sudo docker run hello-world

在这里插入图片描述

docker官网地址：在 Ubuntu |上安装 Docker 引擎Docker 文档

Kubernetes安装步骤（Linux）

一、前置条件（要确认各个结点网络互通）

#各个机器设置自己的域名
hostnamectl set-hostname xxxx

#使用sestatus命令显示SELinux是启用还是禁用
sestatus
#如果未安装sestatus我们可以使用以下命令将其安装
sudo apt install policycoreutils
# 将 SELinux 设置为 disabled 模式（临时） 
SELINUX=disabled
# 修改nano /etc/selinux/config参数 SELINUX = disabled（永久，重启系统生效）
sudo vim /etc/selinux/config

#关闭swap（临时）
sudo swapoff -a  
#关闭swap（永久，重启系统生效）
sudo sed -ri 's/.*swap.*/#&/' /etc/fstab

#允许 iptables 检查桥接流量
cat <<EOF | sudo tee /etc/modules-load.d/k8s.conf
br_netfilter
EOF

cat <<EOF | sudo tee /etc/sysctl.d/k8s.conf
net.bridge.bridge-nf-call-ip6tables = 1
net.bridge.bridge-nf-call-iptables = 1
EOF
sudo sysctl --system

二、安装kubelet、kubeadm、kubectl

sudo apt-get update
sudo apt-get install -y apt-transport-https ca-certificates curl

#下载 Google Cloud 公开签名秘钥（阿里云镜像）：
sudo curl -fsSLo /usr/share/keyrings/kubernetes-archive-keyring.gpg  https://mirrors.aliyun.com/kubernetes/apt/doc/apt-key.gpg


#添加 Kubernetes apt 仓库（阿里云镜像）：
echo "deb [signed-by=/usr/share/keyrings/kubernetes-archive-keyring.gpg] http://mirrors.aliyun.com/kubernetes/apt kubernetes-xenial main" | sudo tee /etc/apt/sources.list.d/kubernetes.list

sudo apt-get update
#查看可安装版本
sudo apt-cache madison kubelet

#安装
sudo apt install -y kubelet=1.21.10-00 kubeadm=1.21.10-00 kubectl=1.21.10-00
#立即生效
sudo systemctl enable --now kubelet

三、初始化主节点

先将主节点设置域名

#所有机器添加master域名映射，192.168.1.125是主节点ip，其他集群都执行这条语句
echo "192.168.1.125  cluster-endpoint" >> sudo /etc/hosts
#加完之后ping一下
ping cluster-endpoint

主节点初始化

sudo kubeadm init \
--apiserver-advertise-address=192.168.1.125 \
--control-plane-endpoint=cluster-endpoint \
--image-repository  registry.cn-hangzhou.aliyuncs.com/google_containers \
--kubernetes-version v1.21.10 \
--service-cidr=10.96.0.0/12 \
--pod-network-cidr=10.244.0.0/16

ps:如果用阿里云服务器的话，出现库kubeadm init 超时情况：把--apiserver-advertise-address=ip 这个参数对应的ip换成内网ip，不要用公网

#看kubelet启动状态
sudo systemctl status kubelet
#如果没有启动查看一下日志，再根据日志解决对应问题
journalctl -xeu kubelet

初始化完成之后，回看到一个这样的信息，留存一下，后续操作需要使用

Your Kubernetes control-plane has initialized successfully!

To start using your cluster, you need to run the following as a regular user:

  mkdir -p $HOME/.kube
  sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
  sudo chown $(id -u):$(id -g) $HOME/.kube/config

Alternatively, if you are the root user, you can run:

  export KUBECONFIG=/etc/kubernetes/admin.conf

You should now deploy a pod network to the cluster.
Run "kubectl apply -f [podnetwork].yaml" with one of the options listed at:
  https://kubernetes.io/docs/concepts/cluster-administration/addons/

You can now join any number of control-plane nodes by copying certificate authorities
and service account keys on each node and then running the following as root:

#加入一个控制节点
  kubeadm join cluster-endpoint:6443 --token 24fldo.6z7mn6the365gckm \
    --discovery-token-ca-cert-hash sha256:38e42b0ca861a9fa27b11b1ab9c9c0e2f2428947c790dfd20b77ea3dd2ffa7f6 \
    --control-plane 
#加入一个worker节点
Then you can join any number of worker nodes by running the following on each as root:

kubeadm join cluster-endpoint:6443 --token 24fldo.6z7mn6the365gckm \
    --discovery-token-ca-cert-hash sha256:38e42b0ca861a9fa27b11b1ab9c9c0e2f2428947c790dfd20b77ea3dd2ffa7f6

执行上述脚本中的语句

 mkdir -p $HOME/.kube
  sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
  sudo chown $(id -u):$(id -g) $HOME/.kube/config

安装网络组件（我安装的是calico）

curl https://docs.projectcalico.org/manifests/calico.yaml -O
#根据配置文件，给集群创建资源
sudo kubectl apply -f calico.yaml

四、加入主节点

#加入一个控制节点
sudo kubeadm join cluster-endpoint:6443 --token 24fldo.6z7mn6the365gckm \
    --discovery-token-ca-cert-hash sha256:38e42b0ca861a9fa27b11b1ab9c9c0e2f2428947c790dfd20b77ea3dd2ffa7f6 \
    --control-plane 
#加入一个worker节点
Then you can join any number of worker nodes by running the following on each as root:

sudo kubeadm join cluster-endpoint:6443 --token 24fldo.6z7mn6the365gckm \
    --discovery-token-ca-cert-hash sha256:38e42b0ca861a9fa27b11b1ab9c9c0e2f2428947c790dfd20b77ea3dd2ffa7f6

令牌过期，获取新令牌

#主节点执行
sudo kubeadm token create --print-join-command

ps:如果用阿里云服务器的话,访问不了主节点6443端口的话，先去确认一下安全组相应端口开没开

五、验证集群

 kubectl get nodes

六、安装dashbord

1、安装

sudo kubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/v2.3.1/aio/deploy/recommended.yaml

如果上述地址访问不了，可以手动创建一个yaml文件，添加如下配置

应用配置

#dashbord.yaml是自己手动创建的ymal文件
sudo kubectl apply -f dashbord.yaml

2、设置端口

执行这条命令

sudo kubectl edit svc kubernetes-dashboard -n kubernetes-dashboard

将type: ClusterIP 改为 type: NodePort

# 找到端口，在安全组放行
sudo kubectl get svc -A |grep kubernetes-dashboard

3、验证

访问： https://集群任意IP:端口 https://139.198.165.238:32759

4、创建访问账号

创建一个yaml文件，添加如下配置

apiVersion: v1
kind: ServiceAccount
metadata:
  name: admin-user
  namespace: kubernetes-dashboard
---
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRoleBinding
metadata:
  name: admin-user
roleRef:
  apiGroup: rbac.authorization.k8s.io
  kind: ClusterRole
  name: cluster-admin
subjects:
- kind: ServiceAccount
  name: admin-user
  namespace: kubernetes-dashboard

应用配置

#dash.yaml是自己手动创建的ymal文件
kubectl apply -f dash.yaml

5、令牌访问

#获取访问令牌
kubectl -n kubernetes-dashboard get secret $(kubectl -n kubernetes-dashboard get sa/admin-user -o jsonpath="{.secrets[0].name}") -o go-template="{{.data.token | base64decode}}"

Kubeedge安装步骤（Linux）

使用keadm工具安装

一、前置条件（云端、边缘端都需要操作）

1）首先确认主机已安装好docker、k8s、go，下图是k8s和kubeedge版本兼容图
在这里插入图片描述

请下载对应的版本

2）准备好keadm的安装包，随便放一个目录，下载地址：Release KubeEdge v1.9.2 release · kubeedge/kubeedge · GitHub，根据架构选择对应安装包

在这里插入图片描述

3）解压

 #keadm-v1.9.2-linux-arm64.tar.gz修改成相应安装包名称
 tar -zxvf keadm-v1.9.2-linux-arm64.tar.gz

4）keadm添加到环境变量中

进入到**/keadm安装目录/keadm/** 下

#将其配置进入环境变量，方便使用
cp keadm /usr/sbin/

5）下载好kubeedge源码，随便放一个目录，下载地址：Release KubeEdge v1.9.2 release · kubeedge/kubeedge · GitHub
在这里插入图片描述

# 进入到kubeedge源码所在目录，执行下面命令解压
tar -zxvf kubeedge-1.9.2.tar

6）下载好kubeedge安装包放到/etc/kubeedge 目录下，下载地址：Release KubeEdge v1.9.2 release · kubeedge/kubeedge · GitHub，根据架构选择对应安装包
在这里插入图片描述

二、安装keadm（云端）

1、keadm init

sudo keadm init --advertise-address=192.168.1.125 --kubeedge-version=1.9.2

--advertise-address 云端地址

2、问题

keadm init的时候如果出现raw.githubusercontent.com 访问不了的话，编辑 /etc/hosts 文件，添加 185.199.108.133 raw.githubusercontent.com

sudo vim  /etc/hosts

在这里插入图片描述

之后，在重新执行上面keadm init命令
如果还不行，可以用我下载好的文件，放到相应目录（myData: 资料相关 - Gitee.com）

1）devices_v1alpha2_device.yaml(用于设备接入的CRD)下载失败

mkdir -p /etc/kubeedge/crds/devices && mkdir -p /etc/kubeedge/crds/reliablesyncs

cp devices_v1alpha2_device.yaml /etc/kubeedge/crds/devices/

2）devices_v1alpha2_devicemodel.yaml下载失败

cp devices_v1alpha2_devicemodel.yaml /etc/kubeedge/crds/devices/

3）其他xxx…yaml下载失败，将下载文件放到/etc/kubeedge/crds/

4）cloudcore.service下载失败，将文件放到/etc/kubeedge/

3、检查cloudcore是否启动

ps -ef|grep cloudcore

在这里插入图片描述

三、安装keadm（边缘端）

1、keadm join

sudo keadm join --cloudcore-ipport=192.168.1.125:10000 --edgenode-name=node --kubeedge-version=1.9.2 --token=3dc13e89ee6b907f7346786d018d0fa4c1efa7ddb0017607c7512bc1b4926449.eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJleHAiOjE2MjM5OTg0ODd9.hTQMyupZd5d_e5uOVtz3RVsfe9H_BSFnwuLzPRy2ZUg

参数说明

cloudcore-ipport：云端的ip和port

edgenode-name：边缘的hostname

kubeedge-version：安装的kubeedge版本

token:在云端输入命令keadm gettoken返回的token

2、问题

如果edgecore.service下载失败，编辑 /etc/hosts 文件，添加 185.199.108.133 raw.githubusercontent.com

sudo vim  /etc/hosts

在这里插入图片描述

如果还不行，可以用我下载好的文件，放到相应目录（myData: 资料相关 - Gitee.com）

下载edgecore.service，将文件放到/etc/kubeedge/

之后，在重新执行上面keadm join的命令

3、启用kubectl logs功能

1）确保可以找到 Kubernetes 的 ca.crt 和 ca.key 文件

ls /etc/kubernetes/pki/

2）设置 CLOUDCOREIPS 环境。环境变量设置为指定的 cloudcore 的IP地址

export CLOUDCOREIPS="192.168.1.125"

3）查看环境变量是否加入成功

echo $CLOUDCOREIPS

4）在云端节点上为 CloudStream 生成证书

进入kubeedge源码目录/build/tools下有个 certgen.sh文件

[外链图片转存失败,源站可能有防盗链机制,建议将图片保存下来直接上传在这里插入图片描述

复制到/etc/kubeedge/目录下

cp /opt/kubeedge-1.9.2/build/tools/certgen.sh /etc/kubeedge/

从 certgen.sh 生成证书

bash /etc/kubeedge/certgen.sh stream

在主机上设置 iptables。（此命令应该在每个apiserver部署的节点上执行。）（

注意: 您需要先设置CLOUDCOREIPS变量

iptables -t nat -A OUTPUT -p tcp --dport 10350 -j DNAT --to $CLOUDCOREIPS:10003

端口10003和10350是 CloudStream 和 Edgecore 的默认端口，如果已发生变更，请使用自己设置的端口。

如果您不确定是否设置了iptables，并且希望清除所有这些表。（如果您错误地设置了iptables，它将阻止您使用 kubectl logs 功能）可以使用以下命令清理iptables规则：

iptables -F && iptables -t nat -F && iptables -t mangle -F && iptables -X

5）在cloudcore和edgecore 中编辑 YAML 文件

#cloud端
sudo vim /etc/kubeedge/config/cloudcore.yaml
#edge端
sudo vim /etc/kubeedge/config/edgecore.yaml

将将 cloudStream 和 edgeStream 设置为 enable: true，将服务器IP更改为 cloudcore IP

在这里插入图片描述

6）重启cloudcore和edgecore

#cloudcore
pkill cloudcore
nohup cloudcore > cloudcore.log 2>&1 &

#edgecore
systemctl restart edgecore.service

4、检查edgecore是否启动

systemctl status edgecore

在这里插入图片描述

如果edgecore没起来，请检查是否是由于 kube-proxy 的缘故，同时杀死这个进程。 kubeedge 默认不纳入该进程，我们使用 edgemesh 来进行替代

注意： 可以考虑避免 kube-proxy 部署在edgenode上。有两种解决方法：

#1. 通过调用 `kubectl edit daemonsets.apps -n kube-system kube-proxy` 添加以下设置：
```yaml
affinity:
    nodeAffinity:
      requiredDuringSchedulingIgnoredDuringExecution:
        nodeSelectorTerms:
          - matchExpressions:
              - key: node-role.kubernetes.io/edge
                operator: DoesNotExist
```

#2. 如果您仍然要运行 `kube-proxy` ，请通过在以下位置添加 `edgecore.service` 中的 env 变量来要求 **edgecore** 不进行检查edgecore.service：

    ```shell
    sudo vi /etc/kubeedge/edgecore.service
    ```

    # 将以下行添加到 **edgecore.service** 文件：

    ```shell
    Environment="CHECK_EDGECORE_ENVIRONMENT=false"
    ```

    # 最终文件应如下所示：

    ```
    Description=edgecore.service

    [Service]
    Type=simple
    ExecStart=/root/cmd/ke/edgecore --logtostderr=false --log-file=/root/cmd/ke/edgecore.log
    Environment="CHECK_EDGECORE_ENVIRONMENT=false"

    [Install]
    WantedBy=multi-user.target
    ```

如果还不行，看一下edgecore日志

journalctl -u edgecore -n 50

例如这个报错是因为 kubelet 的cgroup driver 从docker的配置中读取到不到

在这里插入图片描述

编辑docker的配置文件，修改成edge kubelet需要的cgroup driver即可

vim /etc/docker/daemon.json

"exec-opts": ["native.cgroupdriver=cgroupfs"]

5、检查是否加入cloud端

在cloud输入

kubectl get nodes

在这里插入图片描述

dgecore.service

```

# 将以下行添加到 **edgecore.service** 文件：

```shell
Environment="CHECK_EDGECORE_ENVIRONMENT=false"
```

# 最终文件应如下所示：

```
Description=edgecore.service

[Service]
Type=simple
ExecStart=/root/cmd/ke/edgecore --logtostderr=false --log-file=/root/cmd/ke/edgecore.log
Environment="CHECK_EDGECORE_ENVIRONMENT=false"

[Install]
