Jaeger Install

We will at first install the operators and the CRD before customing and deploying every single component.

Install Elasticsearch

For Elasticsearch, we will install the operator, the CRD and the RABC by running the following commands:

kubectl apply -f https://download.elastic.co/downloads/eck/1.0.0/all-in-one.yaml

Now we will create an Elasticsearch with 6 nodes (3) Master nodes and 3 Data nodes:

kubectl create namespace observability
Kubectl apply -f elasticsearch/elastic.yaml

Install Kafka

Now we can start installing kafka by creating a dedicated namespace:

kubectl create namespace kafka

Next we apply the installation file, including ClusterRoles, ClusterRoleBindings and Custom Resource Definition (CRD).

curl -L https://github.com/strimzi/strimzi-kafka-operator/releases/download/0.16.2/strimzi-cluster-operator-0.16.2.yaml \
  | sed 's/namespace: .*/namespace: kafka/' \
  | kubectl apply -f - -n kafka 

Once the operator and CRD created, we will create the kafka custom ressource :

Kubectl apply -f kafka/kafka.yaml

Notice: Be sure, by checking the logs, that kafka and the elasticsearch cluster are UP & Running before starting the Jaeger installation with the next steps

Install Jaeger

First we will install the operator and the CRD in the observability namespace by running :

kubectl create -f https://raw.githubusercontent.com/jaegertracing/jaeger-operator/master/deploy/crds/jaegertracing.io_jaegers_crd.yaml -n observability
kubectl create -f https://raw.githubusercontent.com/jaegertracing/jaeger-operator/master/deploy/service_account.yaml -n observability
kubectl create -f https://raw.githubusercontent.com/jaegertracing/jaeger-operator/master/deploy/role.yaml -n observability
kubectl create -f https://raw.githubusercontent.com/jaegertracing/jaeger-operator/master/deploy/role_binding.yaml -n observability
kubectl create -f https://raw.githubusercontent.com/jaegertracing/jaeger-operator/master/deploy/operator.yaml -n observability

Before deploying Jaeger we have to get the password from Elasticsearch secret and create a new secret for Jaeger with username and password.

PASSWORD=$(kubectl get secret quickstart-es-elastic-user -n observability -o=jsonpath='{.data.elastic}' | base64 --decode)

kubectl create secret generic jaeger-secret -n observability --from-literal=ES_PASSWORD=${PASSWORD} --from-literal=ES_USERNAME=elastic

Now we can deploy Jaeger :

Kubectl apply -f jaeger/jaeger.yaml

We can notice on the jaeger.yaml that we identified the Kafka configuration used by the collector, to produce the messages, and the ingester to consume the messages.
