部署Dashboard
涉及到的两个镜像可以先下载下来
#安装
kubectl apply -f ~/recommended.yaml
#检查结果
kubectl get pods -A -o wide
kubectl get service -n kubernetes-dashboard -o wide
9.创建dashboard管理员
cat >> dashboard-admin.yaml<<EOF
apiVersion: v1
kind: ServiceAccount
metadata:
labels:
k8s-app: kubernetes-dashboard
name: dashboard-admin
namespace: kubernetes-dashboard
EOF
kubectl apply -f dashboard-admin.yaml
为用户分配权限:
cat >>dashboard-admin-bind-cluster-role.yaml<<EOF
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRoleBinding
metadata:
name: dashboard-admin-bind-cluster-role
labels:
k8s-app: kubernetes-dashboard
roleRef:
apiGroup: rbac.authorization.k8s.io
kind: ClusterRole
name: cluster-admin
subjects:
- kind: ServiceAccount
name: dashboard-admin
namespace: kubernetes-dashboard
EOF
kubectl apply -f dashboard-admin-bind-cluster-role.yaml
访问地址:https://NodeIP:30000
创建service account并绑定默认cluster-admin管理员集群角色:
kubectl create serviceaccount dashboard-admin -n kube-system
kubectl create clusterrolebinding dashboard-admin --clusterrole=cluster-admin --serviceaccount=kube-system:dashboard-admin
kubectl describe secrets -n kube-system $(kubectl -n kube-system get secret | awk \'/dashboard-admin/{print $1}\')
使用输出的token登录Dashboard。
10.部署Prometheus+Grafana+Alertmanager
# git clone https://github.com/coreos/kube-prometheus
# cd kube-prometheus/manifests/
# 修改镜像源
sed -i \'s/quay.io/quay.mirrors.ustc.edu.cn/g\' setup/prometheus-operator-deployment.yaml
sed -i \'s/quay.io/quay.mirrors.ustc.edu.cn/g\' prometheus-prometheus.yaml
sed -i \'s/quay.io/quay.mirrors.ustc.edu.cn/g\' alertmanager-alertmanager.yaml
sed -i \'s/quay.io/quay.mirrors.ustc.edu.cn/g\' kube-state-metrics-deployment.yaml
sed -i \'s/quay.io/quay.mirrors.ustc.edu.cn/g\' node-exporter-daemonset.yaml
sed -i \'s/quay.io/quay.mirrors.ustc.edu.cn/g\' prometheus-adapter-deployment.yaml
# 安装CRD和prometheus-operator
[root@k8s-master manifests]# kubectl apply -f setup/
[root@k8s-master manifests]# kubectl get pod -n monitoring
安装prometheus, alertmanager, grafana, kube-state-metrics, node-exporter等资源,时间较长
[root@k8s-master manifests]# kubectl apply -f .
[root@k8s-master manifests]# kubectl get pod -n monitoring
配置 ingress
cat nginx-ingress.yaml
# 如果打算用于生产环境,请参考 https://github.com/nginxinc/kubernetes-ingress/blob/v1.5.5/docs/installation.md 并根据您自己的情况做进一步定制
