Kubernetes ExternalName Services

Question

Answer 1

Hi, ExternalName Services work as normal services, but while accessing it, it returns CNAME with value that mentioned in externalName, instead of returning cluster-ip of this service

For eg: 

kind: Service

apiVersion: v1

metadata:

  name: my-service

spec:

  type: ExternalName

  externalName: prakhar.example.com

if you curl this then it will redirect you at :http  ://prakhar.example.com

hope this helps, also you can learn more in detail about kubernetes and other devops tools in devops training
