kubernetes v1.27.2集群部署
kubernetes v1.27.2集群部署
1、主机准备
Centos 7.9
2、配置hosts
[root@ops-test-01 ~]# cat >>/etc/hosts <3、关闭防火墙和selinux
[root@ops-test-01 ~]# systemctl stop firewalld.service
[root@ops-test-01 ~]# systemctl disable firewalld.service
[root@ops-test-01 ~]# setenforce 0
[root@ops-test-01 ~]# sed -i "s/SELINUX=enforcing/SELINUX=disabled/g" /etc/selinux/config
4、关闭swap分区
[root@ops-test-01 ~]# swapoff -a
[root@ops-test-01 ~]# sed -i '/swap/s/^/#/g' /etc/fstab
5、配置内核参数和优化
[root@ops-test-01 ~]# cat > /etc/sysctl.d/k8s.conf < /etc/modules-load.d/ipvs.conf < 确认内核模块加载成功
[root@ops-test-01 ~]# lsmod |egrep "ip_vs|nf_conntrack_ipv4"
nf_conntrack_ipv4 19149 0
nf_defrag_ipv4 12729 1 nf_conntrack_ipv4
ip_vs_sh 12688 0
ip_vs_wrr 12697 0
ip_vs_rr 12600 0
ip_vs 145458 6 ip_vs_rr,ip_vs_sh,ip_vs_wrr
nf_conntrack 143360 2 ip_vs,nf_conntrack_ipv4
libcrc32c 12644 3 xfs,ip_vs,nf_conntrack
7、安装containerd
1）安装依赖软件包
[root@ops-test-01 ~]# yum -y install yum-utils device-mapper-persistent-data lvm2
2）添加阿里Docker源
[root@ops-test-01 ~]# yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
3）添加overlay和netfilter模块
[root@ops-test-01 ~]# cat >>/etc/modules-load.d/containerd.conf <4）安装Containerd，这里安装最新版本
[root@ops-test-01 ~]# yum -y install containerd.io
5）创建Containerd的配置文件
[root@ops-test-01 ~]# mkdir -p /etc/containerd
[root@ops-test-01 ~]# containerd config default > /etc/containerd/config.toml
[root@ops-test-01 ~]# sed -i '/SystemdCgroup/s/false/true/g' /etc/containerd/config.toml
[root@ops-test-01 ~]# sed -i '/sandbox_image/s/registry.k8s.io/registry.aliyuncs.com\/google_containers/g' /etc/containerd/config.toml
6）启动containerd
[root@ops-test-01 ~]# systemctl enable containerd
[root@ops-test-01 ~]# systemctl start containerd
三、安装kubectl、kubelet、kubeadm
1、添加阿里kubernetes源
[root@ops-test-01 ~]# cat >/etc/yum.repos.d/kubernetes.repo <2、安装kubectl、kubelet、kubeadm
1）查看所有的可用版本
[root@ops-test-01 ~]# yum list kubelet --showduplicates |grep 1.27
kubelet.x86_64 1.27.1-0 @kubernetes
kubelet.x86_64 1.27.0-0 kubernetes
kubelet.x86_64 1.27.1-0 kubernetes
kubelet.x86_64 1.27.2-0 kubernetes
2）安装当前最新版本1.27.2
[root@ops-test-01 ~]# yum -y install kubectl-1.27.2 kubelet-1.27.2 kubeadm-1.27.2
3）启动kubelet
[root@ops-test-01 ~]# systemctl enable kubelet
[root@ops-test-01 ~]# systemctl start kubelet
四、部署Kubernetes Master
1、初始化Kubernetes集群
1）查看k8s v1.27.2初始化所需要的镜像
[root@ops-test-01 ~]# kubeadm config images list --kubernetes-version=v1.27.2
W0525 13:24:33.579230 7255 images.go:80] could not find officially supported version of etcd for Kubernetes v1.27.2, falling back to the nearest etcd version (3.5.7-0)
registry.k8s.io/kube-apiserver:v1.27.2
registry.k8s.io/kube-controller-manager:v1.27.2
registry.k8s.io/kube-scheduler:v1.27.2
registry.k8s.io/kube-proxy:v1.27.2
registry.k8s.io/pause:3.9
registry.k8s.io/etcd:3.5.7-0
registry.k8s.io/coredns/coredns:v1.10.1
2）初始化
[root@ops-test-01 ~]# kubeadm init --kubernetes-version=1.27.2 \
--apiserver-advertise-address=192.168.2.91 \
--image-repository registry.aliyuncs.com/google_containers \
--service-cidr=10.10.0.0/16 \
--pod-network-cidr=172.16.0.0/16
备注：pod的网段为: 172.16.0.0/16，api server地址为Master本机IP，网段可以自定义，不能冲突。
由于kubeadm 默认从官网k8s.grc.io下载所需镜像，国内无法访问，因此需要通过–image-repository指定阿里云镜像仓库地址。
集群初始化成功后返回如下信息：
[root@ops-test-01 ~]# kubeadm init --kubernetes-version=1.27.2 \
> --apiserver-advertise-address=192.168.2.91 \
> --image-repository registry.aliyuncs.com/google_containers \
> --service-cidr=10.10.0.0/16 \
> --pod-network-cidr=172.16.0.0/16

It is recommended that using "registry.aliyuncs.com/google_containers/pause:3.9" as the CRI sandbox image.

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/
Then you can join any number of worker nodes by running the following on each as root:
kubeadm join 192.168.2.91:6443 --token fm7lxk.bb1zs8kzp49oa2hj \
--discovery-token-ca-cert-hash sha256:b4ac9a62ed634de91e4d708658e6834dd2e8f95ebfcebd7781a23a34e55e3464
注：记录生成的最后部分内容，此内容需要在其它节点加入Kubernetes集群时执行。
2、根据提示创建kubectl
[root@ops-test-01 ~]# mkdir -p $HOME/.kube
[root@ops-test-01 ~]# sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
[root@ops-test-01 ~]# sudo chown $(id -u):$(id -g) $HOME/.kube/config
[root@ops-test-01 ~]# export KUBECONFIG=/etc/kubernetes/admin.conf
3、查看node节点和pod
[root@ops-test-01 ~]# kubectl get node
NAME STATUS ROLES AGE VERSION
ops-test-01 Ready control-plane 2m38s v1.27.2
[root@ops-test-01 ~]# kubectl get pod -A
NAMESPACE NAME READY STATUS RESTARTS AGE
kube-system coredns-7bdc4cb885-cn8gg 0/1 ContainerCreating 0 2m43s
kube-system coredns-7bdc4cb885-fh4p9 0/1 ContainerCreating 0 2m43s

kube-system kube-proxy-r98nf 1/1 Running 0 2m43s
kube-system kube-scheduler-ops-test-01 1/1 Running 0 2m58s
注：node节点为NotReady，因为corednspod没有启动，缺少网络pod
4、安装Pod网络插件calico（CNI）
[root@ops-test-01 ~]# kubectl apply -f https://docs.tigera.io/archive/v3.24/manifests/calico.yaml
poddisruptionbudget.policy/calico-kube-controllers created

[root@ops-test-01 ~]# kubectl get node
NAME STATUS ROLES AGE VERSION
ops-test-01 Ready control-plane 17m v1.27.2
6、从节点加入Kubernetes集群
kubeadm join 192.168.2.91:6443 --token fm7lxk.bb1zs8kzp49oa2hj \
--discovery-token-ca-cert-hash sha256:b4ac9a62ed634de91e4d708658e6834dd2e8f95ebfcebd7781a23a34e55e3464
[root@ops-test-02 ~]# kubeadm join 192.168.2.91:6443 --token fm7lxk.bb1zs8kzp49oa2hj \
> --discovery-token-ca-cert-hash sha256:b4ac9a62ed634de91e4d708658e6834dd2e8f95ebfcebd7781a23a34e55e3464
[preflight] Running pre-flight checks
[preflight] Reading configuration from the cluster...
[preflight] FYI: You can look at this config file with 'kubectl -n kube-system get cm kubeadm-config -o yaml'
[kubelet-start] Writing kubelet configuration to file "/var/lib/kubelet/config.yaml"
[kubelet-start] Writing kubelet environment file with flags to file "/var/lib/kubelet/kubeadm-flags.env"
[kubelet-start] Starting the kubelet
[kubelet-start] Waiting for the kubelet to perform the TLS Bootstrap...
This node has joined the cluster:
* Certificate signing request was sent to apiserver and a response was received.
* The Kubelet was informed of the new secure connection details.
Run 'kubectl get nodes' on the control-plane to see this node join the cluster.
[root@ops-test-03 ~]# kubeadm join 192.168.2.91:6443 --token fm7lxk.bb1zs8kzp49oa2hj \

7、再次查看Node
[root@ops-test-01 ~]# kubectl get nodes
NAME STATUS ROLES AGE VERSION
ops-test-01 Ready control-plane 23m v1.27.2
ops-test-02 Ready 66s v1.27.2
ops-test-03 Ready 26s v1.27.2
8、kubectl命令补全功能
[root@ops-test-01 ~]# yum -y install bash-completion
[root@ops-test-01 ~]# echo "source <(kubectl completion bash)" >> /etc/profile
[root@ops-test-01 ~]# source /etc/profile
----集群安装完成-------------
五，安装ingress
https://kubernetes.github.io/ingress-nginx/deploy/
kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/controller-v1.7.1/deploy/static/provider/cloud/deploy.yaml
