Map ports to hosts
ports:
- containerPort: 8083
hostPort: 8083
- containerPort: 8086
hostPort: 8086
Modify heapster_influxdb:v0.4
heapster_grafana: v2.1.1
sed -i "s/heapster_influxdb:v0.5/heapster_influxdb:v0.4/" influxdb-grafana-controller.yaml
sed -i "s / heapster_grafana: v2.6.0-2 / heapster_grafana: v2.1.1 /" influxdb-grafana-controller.yaml
Comment out the environment variables (keep only the first one)
env:
# This variable is required to setup templates in Grafana.
- name: INFLUXDB_SERVICE_URL
value: http://monitoring-influxdb:8086
# The following env variables are required to make Grafana accessible via
# the kubernetes api-server proxy. On production clusters, we recommend
# removing these env variables, setup auth for grafana, and expose the grafana
# service using a LoadBalancer or a public IP.
# - name: GF_AUTH_BASIC_ENABLED
# value: "false"
# - name: GF_AUTH_ANONYMOUS_ENABLED
# value: "true"
# - name: GF_AUTH_ANONYMOUS_ORG_ROLE
# value: Admin
# - name: GF_SERVER_ROOT_URL

使用浏览器访问influxdb
http://vultr.guest-12的外网IP:8083
--------------------------------------
创建service
kubectl create -f influxdb-service.yaml
修改grafana-service.yaml中spec.type
type: NodePort
kubectl create -f grafana-service.yaml
You have exposed your service on an external port on all nodes in your
cluster. If you want to expose this service to the external internet, you may
need to set up firewall rules for the service port(s) (tcp:32392) to serve traffic.
See http://releases.k8s.io/release-1.3/docs/user-guide/services-firewalls.md for more details.
service "monitoring-grafana" created
根据返回的端口 port(s) (tcp:32392)
使用浏览器访问该地址：http://节点IP：32392
打开grafana界面
