Storage Usage

In this example, you will learn how to use the Storage.

Install Operator

Follow Operator installation instrument to install the operator.

Define Storage with default setting

sample.yaml(use the internal type)

apiVersion: operator.skywalking.apache.org/v1alpha1
kind: Storage
metadata:
  name: sample
spec:
  type: elasticsearch
  connectType: internal
  version: 7.5.1
  instances: 3
  image: docker.elastic.co/elasticsearch/elasticsearch:7.5.1
  security:
    user:
      secretName: default
    tls: true

sample.yaml(use the external type)

apiVersion: operator.skywalking.apache.org/v1alpha1
kind: Storage
metadata:
  name: sample
spec:
  type: elasticsearch
  connectType: external
  address: "https://elasticsearch"
  security:
    user:
      secretName: default

Deploy Storage

Deploy the Storage use the below command:

$ kubectl apply -f sample.yaml

Check the Storage in Kubernetes:

If you deploy the storage with the internal type:

$ kubectl get storage
NAME     INSTANCES      TYPE             VERSION   CONNECTTYPE
sample   3              elasticsearch   7.5.1     internal

If you deploy the storage with the external type:

$ kubectl get storage
NAME     INSTANCES      TYPE             VERSION   CONNECTTYPE
sample                  elasticsearch   7.5.1     external

Check the Statefulset in Kubernetes:

$ kubectl get statefulset   
NAME                    READY   AGE
sample-elasticsearch   3/3     7s

Specify Storage Name in OAP server

Here we modify the default OAP server configuration file,the new yaml file as follows:

apiVersion: operator.skywalking.apache.org/v1alpha1
kind: OAPServer
metadata:
  name: default
spec:
  version: 9.0.0
  instances: 1
  image: apache/skywalking-oap-server:9.0.0
  service:
    template:
      type: ClusterIP
  storage:
    name: sample

Deploy the OAP server use the new yaml file:

$ kubectl apply -f oap.yaml

Check the OAP server in Kubernetes:

$ kubectl get oapserver 
NAME     INSTANCES   RUNNING   ADDRESS
sample   1           1         sample-oap.default

Check whether the pod generated by OAP server is running correctly.

$ kubectl get pod -l app=oap
NAME                          READY   STATUS    RESTARTS   AGE
sample-oap-5bc79567b7-tkw6q   1/1     Running   0          6m31s
