# Sensu
|
||||
|
||||
[Sensu](https://sensuapp.org/) is monitoring that doesn't suck.
|
||||
|
||||
|
||||
## TL;DR;
|
||||
|
||||
```console
|
||||
$ helm install stable/sensu
|
||||
```
|
||||
|
||||
## Introduction
|
||||
|
||||
This chart bootstraps a [Sensu](https://github.com/sstarcher/docker-sensu) deployment on a [Kubernetes](http://kubernetes.io) cluster using the [Helm](https://helm.sh) package manager.
|
||||
|
||||
## Prerequisites
|
||||
|
||||
- Kubernetes 1.4+ with Beta APIs enabled
|
||||
|
||||
## Get this chart
|
||||
|
||||
Download the latest release of the chart from the [releases](../../../releases) page.
|
||||
|
||||
Alternatively, clone the repo if you wish to use the development snapshot:
|
||||
|
||||
```console
|
||||
$ git clone https://github.com/kubernetes/charts.git
|
||||
```
|
||||
|
||||
## Installing the Chart
|
||||
|
||||
To install the chart with the release name `my-release`:
|
||||
|
||||
```console
|
||||
$ helm install --name my-release stable/sensu
|
||||
```
|
||||
|
||||
*Replace the `x.x.x` placeholder with the chart release version.*
|
||||
|
||||
The command deploys Sensu on the Kubernetes cluster in the default configuration. The [configuration](#configuration) section lists the parameters that can be configured during installation.
|
||||
|
||||
> **Tip**: List all releases using `helm list`
|
||||
|
||||
## Uninstalling the Chart
|
||||
|
||||
To uninstall/delete the `my-release` deployment:
|
||||
|
||||
```console
|
||||
$ helm delete my-release
|
||||
```
|
||||
|
||||
The command removes all the Kubernetes components associated with the chart and deletes the release.
|
||||
|
||||
## Configuration
|
||||
|
||||
The following tables lists the configurable parameters of the Sensu chart and their default values.
|
||||
|
||||
| Parameter | Description | Default |
|
||||
| ------------------------------- | ------------------------------- | ---------------------------------------------------------- |
|
||||
| `image` | Sensu image | `sstarcher/sensu` |
|
||||
| `imageTag` | Sensu version | `0.26` |
|
||||
| `imagePullPolicy` | Image pull policy | `IfNotPresent` |
|
||||
| `replicaCount` | Number of sensu replicas | `1` |
|
||||
| `httpPort` | Service port for kubernetes | `80` |
|
||||
| `deis.routable` | Enables routing through the Deis router | `false` |
|
||||
| `deis.domain` | The service name for deis to route | `sensu` |
|
||||
| `server.resources.requests.cpu` | CPU request for sensu server | `100m` |
|
||||
| `server.resources.requests.memory` | Memory request for sensu server | `100Mi` |
|
||||
| `server.resources.limits.cpu` | CPU limit for sensu server | `` |
|
||||
| `server.resources.limits.memory` | Memory limit for sensu server | `` |
|
||||
| `api.resources.requests.cpu` | CPU request for api server | `50m` |
|
||||
| `api.resources.requests.memory` | Memory request for api server | `100Mi` |
|
||||
| `api.resources.limits.cpu` | CPU limit for api server | `` |
|
||||
| `api.resources.limits.memory` | Memory limit for api server | `` |
|
||||
| `REDIS_PORT` | Default port for redis | `6379` |
|
||||
| `REDIS_DB` | The Redis instance DB to use/select | `0` |
|
||||
| `REDIS_AUTO_RECONNECT` | Reconnect to Redis in the event of a connection failure | `true` |
|
||||
| `REDIS_RECONNECT_ON_ERROR` | Reconnect to Redis in the event of a Redis error, e.g. READONLY | `true` |
|
||||
|
||||
Configuration reference for sensu [Sensu/Docs](https://sensuapp.org/docs/latest/reference/)
|
||||
|
||||
```console
|
||||
$ helm install --name my-release \
|
||||
--set imageTag=0.26.5 \
|
||||
stable/sensu
|
||||
```
|
||||
|
||||
The above command sets the Sensu version to `0.26.5`.
|
||||
|
||||
Alternatively, a YAML file that specifies the values for the above parameters can be provided while installing the chart. For example,
|
||||
|
||||
```console
|
||||
$ helm install --name my-release -f values.yaml stable/sensu
|
||||
```
|
||||
|
||||
> **Tip**: You can use the default [values.yaml](values.yaml)
