Kubernets二进制安装(18)之安装部署Heapster

1.下载heapster镜像

在运维主机(mfyxw50.mfyxw.com)执行

[root@mfyxw50 ~]# docker pull quay.io/bitnami/heapster:1.5.4

2.对heapster打标签并上传至私有仓库

在运维主机(mfyxw50.mfyxw.com)执行

[root@mfyxw50 ~]# docker images | grep heapster
[root@mfyxw50 ~]# docker tag quay.io/bitnami/heapster:1.5.4 harbor.od.com/public/heapster:v1.5.4
[root@mfyxw50 ~]# docker login harbor.od.com
[root@mfyxw50 ~]# docker push harbor.od.com/public/heapster:v1.5.4

3.准备heapster资源配置清单

在运维主机(mfyxw50.mfyxw.com)上执行

[root@mfyxw50 ~]# mkdir -p /data/k8s-yaml/heapster
[root@mfyxw50 ~]# cd /data/k8s-yaml/heapster

heapster的rbac.ymal资源配置清单如下：

[root@mfyxw50 heapster]# cat > /data/k8s-yaml/heapster/rbac.yaml << EOF
apiVersion: v1
kind: ServiceAccount
metadata:
  name: heapster
  namespace: kube-system
---
kind: ClusterRoleBinding
apiVersion: rbac.authorization.k8s.io/v1beta1
metadata:
  name: heapster
roleRef:
  apiGroup: rbac.authorization.k8s.io
  kind: ClusterRole
  name: system:heapster
subjects:
- kind: ServiceAccount
  name: heapster
  namespace: kube-system
EOF

heapster的deployment.yaml资源配置清单如下：

[root@mfyxw50 heapster]# cat > /data/k8s-yaml/heapster/deployment.yaml << EOF
apiVersion: extensions/v1beta1
kind: Deployment
metadata:
  name: heapster
  namespace: kube-system
spec:
  replicas: 1
  template:
    metadata:
      labels:
        task: monitoring
        k8s-app: heapster
    spec:
      serviceAccountName: heapster
      containers:
      - name: heapster
        image: harbor.od.com/public/heapster:v1.5.4
        imagePullPolicy: IfNotPresent
        command:
        - /opt/bitnami/heapster/bin/heapster
        - --source=kubernetes:https://kubernetes.default
EOF

heapster的svc.yaml资源配置清单如下：

[root@mfyxw50 heapster]# cat > /data/k8s-yaml/heapster/svc.yaml << EOF
apiVersion: v1
kind: Service
metadata:
  labels:
    task: monitoring
    # For use as a Cluster add-on (https://github.com/kubernetes/kubernetes/tree/master/cluster/addons)
    # If you are NOT using this as an addon, you should comment out this line.
    kubernetes.io/cluster-service: 'true'
    kubernetes.io/name: Heapster
  name: heapster
  namespace: kube-system
spec:
  ports:
  - port: 80
    targetPort: 8082
  selector:
    k8s-app: heapster
EOF

4.应用heapster资源配置清单

在master节点(mfyxw30.mfyxw.com或mfyxw40.mfyxw.com)任意一台上执行命令即可

[root@mfyxw30 ~]# kubectl apply -f http://k8s-yaml.od.com/heapster/rbac.yaml
[root@mfyxw30 ~]# kubectl apply -f http://k8s-yaml.od.com/heapster/deployment.yaml
[root@mfyxw30 ~]# kubectl apply -f http://k8s-yaml.od.com/heapster/svc.yaml

5.重新登录dashboard查看
