A pod with a web application that is in GKE, can have a subdomain appspot.com ?, just like in GAE.
I have a cluster in GKE, and within this I have some services, including a web application that uses a ngnix ingress. Currently I do not want to acquire a paid domain, but I would like to expose my web application in a subdomain appspot.com, is this possible?
I have read that the applications found in GAE are automatically associated with a subdomain of appspot.com, but is it possible to expose applications in GKE?
Unfortunately, no. Domain appspot.com is specific for GAE and some other fully managed GCloud services but not for GKE. In GKE you have to do everything yourself - create domain, expose your app on load balancer, create record and all that stuff. But domains are so cheap, why not buy one?
