Cerebro for ELK

Posted on | Edited on | In

Cerebro (Github Repo) is a Web UI to examine ELK cluster state as well as issuing REST API calls, similiar to Kibana but it is more straightforward through UIs.

For example, I deploy one cerebro instance on dev cluster and port forward the cerebro service port to my bastion local:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: cerebro-deployment
  labels:
    app: cerebro
spec:
  replicas: 1
  selector:
    matchLabels:
      app: cerebro
  template:
    metadata:
      labels:
        app: cerebro
    spec:
      imagePullSecrets:
      - name: <your image pull secret>
      containers:
      - name: cerebro
        # update to available docker image address and tag
        image: lmenezes/cerebro:0.9.4
        ports:
        - containerPort: 9000
        args:
        # set default elasticsearch cluster endpoint
        - -Dhosts.0.host=http://xxxx:9200

Then executing port forward:

# cerebro-deployment-xxxx is the pod name
# 9123:9000: 9123 is local port, 9000 is pod port
kubectl port-forward cerebro-deployment-xxxx 9123:9000

Then accessing cerebro web UI from the browser by localhost:9123.

There are other forward formats, for example:
