DeepFlow Helm Charts

This repository contains Helm charts for DeepFlow project.

Usage

Prerequisites

• Kubernetes 1.16+
• Helm 3+

Helm must be installed to use the charts. Please refer to Helm's documentation to get started.

Once Helm is set up properly, add the repo as follows:

helm repo add deepflow https://deepflowys.github.io/deepflow
helm repo udpate deepflow

Helm Charts

You can then run helm search repo deepflow to see the charts.

_See helm repo for command documentation._

Installing the Chart

To install the chart with the release name deepflow:

helm install deepflow -n deepflow deepflow/deepflow --create-namespace

Uninstalling the Chart

To uninstall/delete the my-release deployment:

helm delete deepflow -n deepflow

The command removes all the Kubernetes components associated with the chart and deletes the release.

Dependencies

By default this chart installs additional, dependent charts:

• grafana/grafana

Main values block usage:

Global

  password: 
    mysql: deepflow ## mysql root account password
    grafana: deepflow ## grafana admin account password
  replicas: 1 ## Number of replicas for deepflow-server and clickhouse
  nodePort: ## NodePort that requires a fixed port
    clickhouse: 30900
    deepflowServerIngester: 30033
    deepflowServerGrpc: 30035
    deepflowServerSslGrpc: 30135
    deepflowServerhealthCheck: 30417
  ntpServer: ntp.aliyun.com ## ntp server address, you need to ensure that udp 123 port is available
  allInOneLocalStorage: false   ## Whether to enable allInone local storage, if enabled, the local /opt directory is used to store data by default, ignoring the node affinity check, and is not responsible for any data persistence

Affinity:

The affinity of component. Combine global.affinity by 'OR'.
