# Default Backend Server

This is a simple webserver that satisfies the ingress, which means it has to do two things:

 1. Serves a 404 page at `/`

 2. Serves 200 on a `/healthz`

Server respond JSON instead of plain text

Not found page:

```

$ curl http://localhost:8080

{"code":404,"message":"Not found"}

```

Status page:

```

$ curl http://localhost:8080/healthz

{"status":"ok"}

```

## Why?!

In my projects, it's important that alive server respond JSON, even if this is default backend server. This image is only 2mb which is extreamly small compare to others custom error images.

Also I personally think JSON response looks better than html error without formatting

Example usage:

```

apiVersion: extensions/v1beta1

kind: Deployment

metadata:

  name: default-http-backend

  labels:

    app: default-http-backend

  namespace: ingress-nginx

spec:

  replicas: 1

  template:

    metadata:

      labels:

        app: default-http-backend

    spec:

      terminationGracePeriodSeconds: 60

      containers:

      - name: default-http-backend

        image: stiks/defaultbackend-rest:1.0

        livenessProbe:

          httpGet:

            path: /healthz

            port: 8080

            scheme: HTTP

          initialDelaySeconds: 30

          timeoutSeconds: 5

        ports:

        - containerPort: 8080

        resources:

          limits:

            cpu: 10m

            memory: 20Mi

          requests:

            cpu: 10m

            memory: 20Mi
