Searchlight

Searchlight by AppsCode is an alert manager for Kubernetes built around Icinga2.

TL;DR;

$ helm install stable/searchlight

Introduction

This chart bootstraps a Searchlight controller deployment on a Kubernetes cluster using the Helm package manager.

Prerequisites

• Kubernetes 1.7+

Installing the Chart

To install the chart with the release name my-release:

$ helm install --name my-release stable/searchlight

The command deploys Searchlight controller on the Kubernetes cluster in the default configuration. The 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:

$ 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 Searchlight chart and their default values.

Parameter	Description	Default
operator.image	operator container image	appscode/searchlight
operator.tag	operator image tag	4.0.0
icinga.image	icinga container image	appscode/icinga
icinga.tag	icinga container image tag	4.0.0-k8s
ido.image	ido container image	appscode/postgress
ido.tag	ido container image tag	9.5-alpine
imagePullSecrets	Specify image pull secrets	nil (does not add image pull secrets to deployed pods)
imagePullPolicy	Image pull policy	IfNotPresent
criticalAddon	If true, installs Searchlight operator as critical addon	false
logLevel	Log level for operator	3
nodeSelector	Node labels for pod assignment	{}
rbac.create	install required rbac service account, roles and rolebindings	false
rbac.serviceAccountName	ServiceAccount Searchlight will use (ignored if rbac.create=true)	default

Specify each parameter using the --set key=value[,key=value] argument to helm install. For example:

$ helm install --name my-release --set image.tag=v0.2.1 stable/searchlight

Alternatively, a YAML file that specifies the values for the parameters can be provided while installing the chart. For example:

$ helm install --name my-release --values values.yaml stable/searchlight

RBAC

By default the chart will not install the recommended RBAC roles and rolebindings.

You need to have the flag --authorization-mode=RBAC on the api server. See the following document for how to enable RBAC.

To determine if your cluster supports RBAC, run the the following command:

$ kubectl api-versions | grep rbac

If the output contains "beta", you may install the chart with RBAC enabled (see below).

Enable RBAC role/rolebinding creation

To enable the creation of RBAC resources (On clusters with RBAC). Do the following:

$ helm install --name my-release stable/searchlight --set rbac.create=true
