通过kubeadm安装kubernetes高可用集群(支持docker和containerd作为kubernetes的容器运行时)

部署节点信息

hostname ip address comment
k8s-master01 192.168.0.101 kubernetes 控制平面主机 master01
k8s-master02 192.168.0.102 kubernetes 控制平面主机 master02
k8s-master03 192.168.0.103 kubernetes 控制平面主机 master03
k8s-vip 192.168.0.100 kubernetes 浮动IP，通过keepalived创建，如果使用公有云请预先申请该浮动IP 
# 各节点请添加主机名解释

架构说明

  • 演示需要，只部署3个高可用的master节点
  • 使用keepalived和nginx作为高可用的负载均衡器，通过dorycli命令行工具生成负载均衡器的配置，并通过nerdctl部署负载均衡器
  • 容器运行时使用containerd

  • 初始化高可用kubernetes集群
# 在k8s-master01上使用kubeadm-config.yaml配置文件初始化高可用集群
kubeadm init --config=kubeadm-config.yaml --upload-certs
# kubeadm init命令将会输出以下提示，使用该提示在其他master节点执行join操作
You can now join any number of the control-plane node running the following command on each as root:

  kubeadm join 192.168.0.100:16443 --token tgszyf.c9dicrflqy85juaf \
    --discovery-token-ca-cert-hash sha256:xxx \
    --control-plane --certificate-key xxx

Please note that the certificate-key gives access to cluster sensitive data, keep it secret!
As a safeguard, uploaded-certs will be deleted in two hours; If necessary, you can use
"kubeadm init phase upload-certs --upload-certs" to reload certs afterward.

Then you can join any number of worker nodes by running the following on each as root:

kubeadm join 192.168.0.100:16443 --token tgszyf.c9dicrflqy85juaf \
    --discovery-token-ca-cert-hash sha256:xxx 


  kubeadm join 192.168.0.100:16443 --token tgszyf.c9dicrflqy85juaf \
    --discovery-token-ca-cert-hash sha256:xxx \
    --control-plane --certificate-key xxx

# 在k8s-master02 和 k8s-master03节点上执行以下命令，把k8s-master02 和 k8s-master03加入到高可用kubernetes集群
# 记住kubeadm join命令需要设置--cri-socket unix:///var/run/containerd/containerd.sock
kubeadm join 192.168.0.100:16443 --token tgszyf.c9dicrflqy85juaf \

    k8s-app: kubernetes-dashboard
  type: NodePort
EOF

# 创建管理员serviceaccount
kubectl create serviceaccount -n kube-system admin-user --dry-run=client -o yaml | kubectl apply -f -

# 创建管理员clusterrolebinding
kubectl create clusterrolebinding admin-user --clusterrole=cluster-admin --serviceaccount=kube-system:admin-user --dry-run=client -o yaml | kubectl apply -f -

# 手动创建serviceaccount的secret
cat << EOF | kubectl apply -f -
apiVersion: v1
kind: Secret
metadata:
  name: admin-user-secret
  namespace: kube-system
  annotations:
    kubernetes.io/service-account.name: admin-user
type: kubernetes.io/service-account-token
EOF

# 获取kubernetes管理token
kubectl -n kube-system get secret admin-user-secret -o jsonpath='{ .data.token }' | base64 -d

# 使用浏览器访问kubernetes-dashboard: https://k8s-vip:30000
# 使用kubernetes管理token登录kubernetes-dashboard

[可选] 安装ingress控制器 traefik

  • 要使用kubernetes的ingress功能，必须安装ingress controller，推荐使用traefik

  • 要了解更多，请阅读官方网站文档: traefik

  • 在kubernetes所有master节点部署traefik:

# 拉取 traefik helm repo
helm repo add traefik https://traefik.github.io/charts
helm fetch traefik/traefik --untar

# 以daemonset方式部署traefik
cat << EOF > traefik.yaml
deployment:
  kind: DaemonSet
image:
  name: traefik
  tag: v2.6.5
ports:
  web:
    hostPort: 80
  websecure:
    hostPort: 443
service:
  type: ClusterIP
EOF

# 安装traefik
kubectl create namespace traefik --dry-run=client -o yaml | kubectl apply -f -
helm install -n traefik traefik traefik/ -f traefik.yaml

# 检查安装情况
helm -n traefik list
kubectl -n traefik get pods -o wide
kubectl -n traefik get services -o wide

# 检验traefik安装是否成功，如果输出 404 page not found 表示成功
curl k8s-vip
curl -k https://k8s-vip

[可选] 安装性能数据采集工具 metrics-server

# 拉取镜像
docker pull registry.aliyuncs.com/google_containers/metrics-server:v0.6.1
docker tag registry.aliyuncs.com/google_containers/metrics-server:v0.6.1 k8s.gcr.io/metrics-server/metrics-server:v0.6.1

# 获取metrics-server安装yaml
curl -O -L https://github.com/kubernetes-sigs/metrics-server/releases/download/v0.6.1/components.yaml
# 添加--kubelet-insecure-tls参数
sed -i 's/- args:/- args:\n        - --kubelet-insecure-tls/g' components.yaml
# 安装metrics-server
kubectl apply -f components.yaml

# 等待metrics-server正常
kubectl -n kube-system get pods -l=k8s-app=metrics-server

# 查看节点的metrics
kubectl top nodes
NAME           CPU(cores)   CPU%   MEMORY(bytes)   MEMORY%   
k8s-master01   146m         7%     2284Mi          59%       
k8s-master02   123m         6%     2283Mi          59%       
k8s-master03   114m         5%     2180Mi          57%
  • 安装metrics-server后kubernetes-dashboard也可以显示性能数据

[可选] 安装服务网格 istio

  • 要使用服务网格的混合灰度发布能力，需要部署istio服务网格
  • 要了解更多，请阅读istio官网文档: istio.io
# 安装istioctl，客户端下载地址 https://github.com/istio/istio/releases/tag/1.18.2

# 下载并安装istioctl
wget https://github.com/istio/istio/releases/download/1.18.2/istioctl-1.18.2-linux-amd64.tar.gz
tar zxvf istioctl-1.18.2-linux-amd64.tar.gz
mv istioctl /usr/bin/

# 确认istioctl版本
istioctl version

# 使用istioctl部署istio到kubernetes
istioctl install --set profile=demo \
--set values.gateways.istio-ingressgateway.type=ClusterIP \
--set values.global.imagePullPolicy=IfNotPresent \
--set values.global.proxy_init.resources.limits.cpu=100m \
--set values.global.proxy_init.resources.limits.memory=100Mi \
--set values.global.proxy.resources.limits.cpu=100m \
--set values.global.proxy.resources.limits.memory=100Mi

# 检查istio部署情况
kubectl -n istio-system get pods,svc

[可选] 应用上云引擎 Dory-Engine

🚀🚀🚀 Dory-Engine平台工程最佳实践 (https://www.bilibili.com/video/BV1oM4y117Pj/)

  • Dory-Engine 是一个非常简单的应用上云引擎，开发人员不用学、不用写、不用配就可以自行把自己编写的程序从源代码，编译、打包、部署到各类k8s环境或者主机环境中。
  1. 不用学: 不需要学习如何编写复杂的上云脚本和如何部署应用到k8s，所有配置都所见即所得一看就懂
  2. 不用写: 不需要编写复杂的构建、打包、部署的上云脚本，也不需要编写复杂的k8s应用部署文件，只需要几项简单的配置就可以设置好自己的上云流水线
  3. 不用配: 不需要配置各个DevOps工具链和k8s环境如何互相配合完成应用上云，项目一开通所有工具链和环境自动完成配置

🚀🚀🚀 使用dorycli安装部署Dory-Engine (https://www.bilibili.com/video/BV1aG411D7Sj/)
