NATS GUI in kubernetes

 

In this post we deploy NATS GUI in kubernetes.

NATS GUI is a very simple and nice tool to view NATS messages. Its deployment is also super simple. We include a service and a deployment.

The service:

apiVersion: v1
kind: Service
metadata:
  name: natsgui-service
spec:
  selector:
    configid: natsgui-container
  type: ClusterIP
  ports:
    - port: 80
      targetPort: 31311
      name: tcp-api
      protocol: TCP

The deployment:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: natsgui-deployment
spec:
  replicas: 1
  selector:
    matchLabels:
      configid: natsgui-container
  template:
    metadata:
      labels:
        configid: natsgui-container        
    spec:
      containers:
        - name: natsgui
          image: ghcr.io/nats-nui/nui:latest
          imagePullPolicy: IfNotPresent
          volumeMounts:
            - mountPath: /db
              name: db
      volumes:
        - emptyDir: {}
          name: db

That's all.

Now we can see the messages in queues. We can also use wildcards, for example:

Another nice feature is the ability to click on  the arrow (near the X to close window). This allows us to save the message details open while checking another message.
