how to set dns to azure kubenetes(acs) services?

I am new to azure. I created an azure acs with kubenetes by using the following config(part of the whole file). 

  - apiVersion: v1
    kind: Service
    metadata:
      name: my-web
    spec:
      type: LoadBalancer
      ports:
      - port: 80
        targetPort: 3000
      selector:
        app: my-web

The service can be visited, but only via IP address. There is no secondary dns(like: xxx.azurewebsite.com) generated. Currently, I use A record points to the ip address. It works, but I am afraid the ip address will be changed, and I have to manually change the dns A record. Just asking if there is a way to generate some stable dns for acs services?

Solution

  • Just asking if there is a way to generate some stable dns for acs services?

    We can via Azure portal to change the public IP address to static, in this way, restart the service will not change the IP.

    But in Azure, if we delete the k8s service, the Public IP address will collected by Azure platform, and we will lose this IP address. For now, Azure does not support to keep the public IP address for k8s service.
