jaeger-operator

jaeger-operator is a Kubernetes operator.

Install

$ helm install jaegertracing/jaeger-operator

Introduction

This chart bootstraps a jaeger-operator deployment on a Kubernetes cluster using the Helm package manager.

Prerequisites

• Kubernetes 1.16+

Installing the Chart

Add the Jaeger Tracing Helm repository:

$ helm repo add jaegertracing https://jaegertracing.github.io/helm-charts

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

$ helm install --name my-release jaegertracing/jaeger-operator

The command deploys jaeger-operator 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 deployment:

$ helm delete my-release

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

Configuration

The following table lists the configurable parameters of the jaeger-operator chart and their default values.

Parameter	Description	Default
image.repository	Controller container image repository	jaegertracing/jaeger-operator
image.tag	Controller container image tag	1.21.2
image.pullPolicy	Controller container image pull policy	IfNotPresent
jaeger.create	Jaeger instance will be created	false
jaeger.spec	Jaeger instance specification	{}
crd.install	CustomResourceDefinition will be installed	true
rbac.create	All required roles and rolebindings will be created	true
serviceAccount.create	Service account to use	true
rbac.pspEnabled	Pod security policy for pod will be created and included in rbac role	false
rbac.clusterRole	ClusterRole will be used by operator ServiceAccount	false
serviceAccount.name	Service account name to use. If not set and create is true, a name is generated using the fullname template	nil
resources	K8s pod resources	None
nodeSelector	Node labels for pod assignment	{}
tolerations	Toleration labels for pod assignment	[]
affinity	Affinity settings for pod assignment	{}
securityContext	Security context for pod	{}

Specify each parameter you'd like to override using a YAML file as described above in the installation section.

You can also specify any non-array parameter using the --set key=value[,key=value] argument to helm install. For example,

$ helm install jaegertracing/jaeger-operator --name my-release \
    --set rbac.create=false

After the Helm Installation

Creating a new Jaeger instance

The simplest possible way to install is by creating a YAML file like the following:

apiVersion: jaegertracing.io/v1
kind: Jaeger
metadata:
  name: simplest

The YAML file can then be used with kubectl:

$ kubectl apply -f simplest.yaml

Creating a new Jaeger with ElasticSearch

To do that you need to have an ElasticSearch installed in your Kubernetes cluster or install one using the Helm Chart available for that.

After that just deploy the following manifest:

# setup an elasticsearch with `make es`
apiVersion: jaegertracing.io/v1
kind: Jaeger
metadata:
  name: simple-prod
spec:
  strategy: production
  storage:
    type: elasticsearch
    options:
      es:
        server-urls: http://elasticsearch:9200
        username: elastic
        password: changeme

The YAML file can then be used with kubectl:

$ kubectl apply -f simple-prod.yaml
