[rootminikube ~]# lscpu 2. Docker安装
# 移除旧的docker
[rootminikube ~]# sudo yum remove docker \docker-client \docker-client-latest \docker-common \docker-latest \docker-latest-logrotate \docker-logrotate \docker-engine# 安装第三方依赖库
[rootminikube ~]# sudo yum install -y yum-utils# 添加Docker-ce仓库
[rootminikube ~]# sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo# 安装docker相关安装包
[rootminikube ~]# sudo yum install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin# 启动docker服务
[rootminikube ~]# sudo systemctl start docker3. minikube安装
[rootminikube ~]# curl -LO https://storage.googleapis.com/minikube/releases/latest/minikube-latest.x86_64.rpm[rootminikube ~]# sudo rpm -Uvh minikube-latest.x86_64.rpm4. kubectl安装
[rootminikube ~]# yum install -y kubectl5. Helm安装
[rootminikube ~]# curl -fsSL -o get_helm.sh https://raw.githubusercontent.com/helm/helm/master/scripts/get-helm-3[rootminikube ~]# chmod 700 get_helm.sh[rootminikube ~]# ./get_helm.sh6. 启动Kubernetes集群v1.28.3
[rootminikube ~]# minikube start --kubernetes-versionv1.28.3 --memory6gRocky 9.2 上的 minikube v1.32.0
❗ 当提供 --force 参数时minikube 将跳过各种验证这可能会导致意外行为
✨ 自动选择 docker 驱动。其他选项none, sshThe docker driver should not be used with root privileges. If you wish to continue as root, use --force.如果您在VM中运行 minikube请考虑使用 --drivernone:https://minikube.sigs.k8s.io/docs/reference/drivers/none/使用具有 root 权限的 Docker 驱动程序正在集群 minikube 中启动控制平面节点 minikube正在拉取基础镜像 ...正在下载 Kubernetes v1.28.3 的预加载文件... preloaded-images-k8s-v18-v1...: 403.35 MiB / 403.35 MiB 100.00% 1.60 Mi gcr.io/k8s-minikube/kicbase...: 453.90 MiB / 453.90 MiB 100.00% 1.70 MiCreating docker container (CPUs2, Memory2200MB) ...正在 Docker 24.0.7 中准备 Kubernetes v1.28.3…▪ 正在生成证书和密钥...▪ 正在启动控制平面...▪ 配置 RBAC 规则 ...配置 bridge CNI (Container Networking Interface) ...正在验证 Kubernetes 组件...▪ 正在使用镜像 gcr.io/k8s-minikube/storage-provisioner:v5启用插件 storage-provisioner, default-storageclass完成kubectl 现在已配置默认使用minikube集群和default命名空间# 查看集群状态
[rootminikube ~]# minikube status
minikube
type: Control Plane
host: Running
kubelet: Running
apiserver: Running
kubeconfig: Configured7. 使用helm安装Prometheus
[rootminikube ~]# kubectl create ns monitoring
namespace/monitoring created[rootminikube ~]# helm repo add prometheus-community https://prometheus-community.github.io/helm-charts
prometheus-community has been added to your repositories[rootminikube ~]# helm repo list
NAME URL
prometheus-community https://prometheus-community.github.io/helm-charts[rootminikube ~]# helm search repo prometheus-community [rootminikube ~]# helm install prometheus prometheus-community/prometheus[rootminikube ~]# kubectl expose service prometheus-server --typeNodePort --target-port9090 --nameprometheus-server-np通过运行以下命令来检查状态
[rootminikube ~]# kubectl get pods -l app.kubernetes.io/instanceprometheus
NAME READY STATUS RESTARTS AGE
prometheus-alertmanager-0 1/1 Running 0 3h15m
prometheus-kube-state-metrics-6b464f5b88-8p49t 1/1 Running 0 3h15m
prometheus-prometheus-node-exporter-b6bzv 1/1 Running 0 3h15m
prometheus-prometheus-pushgateway-7857c44f49-zjddf 1/1 Running 0 3h15m
prometheus-server-6b68fbd54b-df64z 2/2 Running 0 3h15m由于使用的是 Minikube第二个命令prometheus-server使用NodePort. 这样当 Pod 准备就绪时就可以轻松访问 Prometheus Web 界面
minikube service prometheus-server-np[rootminikube ~]# kubectl port-forward svc/prometheus-server-np 30944:80 --address0.0.0.0
Forwarding from 0.0.0.0:30944 - 9090http://192.168.20.20:30944/targets 8. 使用helm安装Grafana
# 将存储库添加到 helm 配置中
[rootminikube ~]# helm repo add grafana https://grafana.github.io/helm-charts
grafana has been added to your repositories[rootminikube ~]# helm repo list
NAME URL
prometheus-community https://prometheus-community.github.io/helm-charts
grafana https://grafana.github.io/helm-charts [rootminikube ~]# helm search repo grafana# 使用提供的图表安装 Grafana
[rootminikube ~]# helm install grafana grafana/grafana
[rootminikube ~]# kubectl expose service grafana --typeNodePort --target-port3000 --namegrafana-np由于使用的是 Minikube为了轻松访问 Grafana 的 Web 界面将该服务公开为NodePort。
注意 Grafana 默认受密码保护为了检索admin用户密码我们可以运行以下命令
kubectl get secret --namespace default grafana -o jsonpath{.data.admin-password} | base64 --decode ; echo
wYISKh0bkkLuQm0TOEOUoVx4M1AW6q70JlOBABS0现在可以使用检索到的用户和密码加载 Grafana Web 界面
[rootminikube ~]# kubectl port-forward svc/grafana-np 30264:80 --address0.0.0.0
Forwarding from 0.0.0.0:30264 - 30009. Grafana的Dashboard设定
rootminikube ~]# kubectl get secret --namespace monitoring grafana -o jsonpath{.data.admin-password} | base64 --decode ; echo
uJEkCoHDGjfkUdvOP8i3djaIvPOggK2tMZcdPKWa[rootminikube ~]# export POD_NAME$(kubectl get pods --namespace monitoring -l app.kubernetes.io/namegrafana,app.kubernetes.io/instancegrafana -o jsonpath{.items[0].metadata.name})[rootminikube ~]# kubectl --namespace monitoring port-forward $POD_NAME 3000
Forwarding from 127.0.0.1:3000 - 3000
Forwarding from [::1]:3000 - 300010. 设定Prometheus数据源 11. 导入Kubernetes Dashboard 12. 实验过程中的常见问题
Grafana 忘记登陆密码 重置密码
[rootminikube ~]# kubectl get pods -A[rootminikube ~]# kubectl exec -it grafana-5657d4fc47-jkdx6 -n default sh/usr/share/grafana $ grafana-cli admin reset-admin-password 123456Admin password changed successfully ✔13. 参考链接
