}
sudo systemctl daemon-reload && sudo systemctl restart docker && sudo docker info
安装cri-dockerd
代码语言:txt复制wget https://github.com/Mirantis/cri-dockerd/releases/download/v0.2.6/cri-dockerd_0.2.6.3-0.ubuntu-focal_amd64.deb
sudo dpkg -i cri-dockerd_0.2.6.3-0.ubuntu-focal_amd64.deb
# 指定依赖镜像地址
sudo vi /usr/lib/systemd/system/cri-docker.service
ExecStart=/usr/bin/cri-dockerd --container-runtime-endpoint fd:// --pod-infra-container-image=registry.aliyuncs.com/google_containers/pause:latest
sudo systemctl daemon-reload && sudo systemctl enable cri-docker && sudo systemctl restart cri-docker
安装kubeadm,kubelet和kubectl

# 开始安装
sudo apt-get update -y && sudo apt-get install -y kubelet kubeadm kubectl && sudo systemctl enable kubelet.service
5. 部署Kubernetes Master
代码语言:txt复制在192.168.11.13(Master)执行
sudo kubeadm init
--apiserver-advertise-address=192.168.11.13
--image-repository registry.aliyuncs.com/google_containers
--kubernetes-version v1.25.4
--service-cidr=10.96.0.0/12

6. 加入节点
在2台node节点上执行
代码语言:txt复制sudo kubeadm join 192.168.11.13:6443 --token o37091.z858bts6jmth9irz
--discovery-token-ca-cert-hash sha256:628a5b50227c93e465adc1ca380cf335e8f639c15c8a92892f9d22b71ac6c2ac
--cri-socket=unix:///var/run/cri-dockerd.sock
代码语言:txt复制上面用到的token,默认token有效期为24小时,当过期之后,该token就不可用了。这时就需要重新创建token,可以直接使用命令快捷生成:
sudo kubeadm token create --print-join-command
加入后在master查看工作节点
代码语言:txt复制tantianran@test-b-k8s-master:~$ kubectl get nodes
NAME STATUS ROLES AGE VERSION
test-b-k8s-master NotReady control-plane 7m57s v1.25.4
test-b-k8s-node01 NotReady <none> 14s v1.25.4
test-b-k8s-node02 NotReady <none> 8s v1.25.4
tantianran@test-b-k8s-master:~$
目前工作节点的状态为NotReady,是因为还没有部署网络插件,等部署完就会处于Ready。
7. 部署容器网络接口(CNI)Calico
Calico是一个纯三层的数据中心网络方案,是目前Kubernetes主流的网络方案。下面开始部署Calico,在master上进行部署操作。
下载calico的YAML:
代码语言:txt复制wget https://docs.projectcalico.org/manifests/calico.yaml
下载完后还需要修改里面定义Pod网络(CALICO_IPV4POOL_CIDR),与前面kubeadm init的 --pod-network-cidr指定的一样。
calico.yaml中CALICO_IPV4POOL_CIDR默认的配置如下:
代码语言:txt复制# - name: CALICO_IPV4POOL_CIDR
# value: "192.168.0.0/16"
取消注释,并修改成与前面kubeadm init的 --pod-network-cidr(10.244.0.0/16)指定的一样。
代码语言:txt复制- name: CALICO_IPV4POOL_CIDR
value: "10.244.0.0/16"
修改完后文件后,开始部署:
代码语言:txt复制# 部署calico
kubectl apply -f calico.yaml
接下来就是比较漫长的等待,等待多久取决于你的网速,如果网络的好的话,就会更快一点,因为它还要拉镜像,而且是3台节点都要拉取相关镜像,下面可以在master上查看位于kube-system命名空间下的pod
代码语言:txt复制tantianran@test-b-k8s-master:~$ kubectl get pods -n kube-system
NAME READY STATUS RESTARTS AGE
calico-kube-controllers-798cc86c47-sg65n 0/1 Pending 0 111s
calico-node-9d2gz 0/1 Init:0/3 0 111s
calico-node-csnwt 0/1 Init:0/3 0 111s
calico-node-g7rk2 0/1 Init:0/3 0 111s
coredns-c676cc86f-p2sgs 0/1 Pending 0 19m
coredns-c676cc86f-pn5zk 0/1 Pending 0 19m
etcd-test-b-k8s-master 1/1 Running 0 19m
kube-apiserver-test-b-k8s-master 1/1 Running 0 19m
kube-controller-manager-test-b-k8s-master 1/1 Running 0 19m
kube-proxy-6bdwl 1/1 Running 0 12m
kube-proxy-d8xgk 1/1 Running 0 19m
kube-proxy-lcw2n 1/1 Running 0 11m
kube-scheduler-test-b-k8s-master 1/1 Running 0 19m
tantianran@test-b-k8s-master:~$
等calico的全部pod状态都为Running的时候,就成功了。到时候你再去查看node的状态,应该也会为Ready了。
刚才提到,在部署calico的过程中3台节点都需要拉取相关镜像,可以到其中1台Node上查看有没有镜像了:
代码语言:txt复制tantianran@test-b-k8s-node02:~$ sudo docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
registry.aliyuncs.com/google_containers/kube-proxy v1.25.4 2c2bc1864279 2 weeks ago 61.7MB
calico/cni v3.24.5 628dd7088041 2 weeks ago 198MB
calico/node v3.24.5 54637cb36d4a 2 weeks ago 226MB
registry.aliyuncs.com/google_containers/pause latest 350b164e7ae1 8 years ago 240kB
tantianran@test-b-k8s-node02:~$
经过一小段时间等待后,calico相关的pod已经都为Running了
代码语言:txt复制tantianran@test-b-k8s-master:~$ kubectl get pods -n kube-system
NAME READY STATUS RESTARTS AGE
calico-kube-controllers-798cc86c47-sg65n 1/1 Running 0 7m45s

kube-proxy-6bdwl 1/1 Running 0 17m
kube-proxy-d8xgk 1/1 Running 0 25m
kube-proxy-lcw2n 1/1 Running 0 17m
kube-scheduler-test-b-k8s-master 1/1 Running 0 25m
tantianran@test-b-k8s-master:~$
继续查看工作节点的状态,也是Ready状态了
代码语言:txt复制tantianran@test-b-k8s-master:~$ kubectl get nodes
NAME STATUS ROLES AGE VERSION
test-b-k8s-master Ready control-plane 26m v1.25.4
test-b-k8s-node01 Ready <none> 19m v1.25.4
test-b-k8s-node02 Ready <none> 19m v1.25.4
tantianran@test-b-k8s-master:~$
到此为止!CNI网络插件calico就已经完成部署啦!
8. 部署Dashboard
Dashboard是官方提供的一个UI,可用于基本管理K8s资源,也是在master上进行部署操作。github项目地址:https://github.com/kubernetes/dashboard
YAML下载地址:
代码语言:txt复制wget https://raw.githubusercontent.com/kubernetes/dashboard/v2.7.0/aio/deploy/recommended.yaml
默认Dashboard只能集群内部访问,下载yaml文件后,修改Service为NodePort类型,暴露到外部:
代码语言:txt复制kind: Service
apiVersion: v1
metadata:
labels:
k8s-app: kubernetes-dashboard
name: kubernetes-dashboard
namespace: kubernetes-dashboard
spec:
ports:
- port: 443
targetPort: 8443
nodePort: 30001 # 增加这个(等会我们访问UI的端口)
selector:
k8s-app: kubernetes-dashboard
type: NodePort # 增加这个(让每个节点都可访问)
开始部署
代码语言:txt复制kubectl apply -f recommended.yaml
这时候,也是需要等待到dashboard相关的pod为Running的状态,它也是要拉镜像,可查看命名空间kubernetes-dashboard下的pod:
代码语言:txt复制tantianran@test-b-k8s-master:~$ kubectl get pods -n kubernetes-dashboard
NAME READY STATUS RESTARTS AGE
dashboard-metrics-scraper-64bcc67c9c-nnzqv 0/1 ContainerCreating 0 17s
kubernetes-dashboard-5c8bd6b59-blpgm 0/1 ContainerCreating 0 17s
tantianran@test-b-k8s-master:~$
等待后,再次查看,dashboard相关的pod已经为Running的状态,说明已经部署好
代码语言:txt复制tantianran@test-b-k8s-master:~$ kubectl get pods -n kubernetes-dashboard
NAME READY STATUS RESTARTS AGE
dashboard-metrics-scraper-64bcc67c9c-nnzqv 1/1 Running 0 2m
kubernetes-dashboard-5c8bd6b59-blpgm 1/1 Running 0 2m
接下来就可以访问任意节点的30001端口访问UI,记得是用https哦
- https://192.168.11.13:30001/#/login
- https://192.168.11.14:30001/#/login
- https://192.168.11.15:30001/#/login
创建登录UI的token
代码语言:txt复制kubectl create serviceaccount dashboard-admin -n kubernetes-dashboard
kubectl create clusterrolebinding dashboard-admin --clusterrole=cluster-admin --serviceaccount=kubernetes-dashboard:dashboard-admin
kubectl create token dashboard-admin -n kubernetes-dashboard
将创建好的token复制进去即可完成登录
最后说明一下,以后所有yaml文件都只在Master节点执行(部署操作),切记!

3.7 时间同步
代码语言:txt复制yum install ntpdate -y
ntpdate time.windows.com
ntpdate ntp1.aliyun.com # 阿里云时钟服务
4. 安装Docker/kubeadm/kubelet/cri-dockerd(所有节点)
4.1 安装Docker-ce
代码语言:txt复制wget https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo -O /etc/yum.repos.d/docker-ce.repo
yum -y install docker-ce
systemctl enable docker && systemctl start docker
4.2 配置镜像下载加速器

--pod-network-cidr=10.244.0.0/16
--cri-socket=unix:///var/run/cri-dockerd.sock
--ignore-preflight-errors=all
在进行更改之前,运行一些列检查,验证系统状态,有些检查只会触发警告,有些检查会被视为错误并退出kubeadm,因此使用 --ignore-preflight-errors=all 忽略检查中的错误。
初始化完成之后,最后会出现下面这样的提示:
代码语言:txt复制Your Kubernetes control-plane has initialized successfully!
To start using your cluster, you need to run the following as a regular user:
要开始使用集群,您需要以普通用户身份运行以下命令:
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:
或者,如果您是root用户,则可以运行:
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/
Then you can join any number of worker nodes by running the following on each as root:
# 记住这个join命令,后面用,作用是在node节点运行这条命令,加入集群
