Run Influxdb On Kubernetes

1. 添加helm仓库：

helm repo add influxdata https://helm.influxdata.com/

2. 安装：

helm upgrade --install my-release influxdata/influxdb

3. 安装结果：

[rancher@fs-192-168-108-3 ~]$ helm upgrade --install my-release influxdata/influxdb
Release "my-release" does not exist. Installing it now.

NOTES:
InfluxDB can be accessed via port 8086 on the following DNS name from within your cluster:

  http://my-release-influxdb.default:8086

You can connect to the remote instance with the influx CLI. To forward the API port to localhost:8086, run the following:

  kubectl port-forward --namespace default $(kubectl get pods --namespace default -l app=my-release-influxdb -o jsonpath='{ .items[0].metadata.name }') 8086:8086

You can also connect to the influx CLI from inside the container. To open a shell session in the InfluxDB pod, run the following:

  kubectl exec -i -t --namespace default $(kubectl get pods --namespace default -l app=my-release-influxdb -o jsonpath='{.items[0].metadata.name}') /bin/sh

To view the logs for the InfluxDB pod, run the following:

  kubectl logs -f --namespace default $(kubectl get pods --namespace default -l app=my-release-influxdb -o jsonpath='{ .items[0].metadata.name }')
