I could make the pods, services and deployments running on my Windows 10 (enterprise) laptop. And I had added the IP – DNS mapping to C:\Windows\System32\drivers\etc\hosts. However for some reason it is not working as expected. So I have a couple of questions as below –

1> Do we need to set up this IP address and DNS mapping in the hosts file? If yes, which IP address should I map to “microservices.info” in the hosts file. Currently I mapped the one which is returned by IP Config.

2> I am using the Kubernetes engine that comes packed with Docker for Desktop (windows installer). I could not run Minikube (though I could install it ), because my laptop does not have sufficient memory. Can your project be deployed and tested, with this constraint ?

Sorry about my ignorance. Please help. Thank you!

Mandar

Hi,
1. You need to map your VM with Kubernetes ip address. I don’t know what’s ip address when you use Docker Desktop (maybe localhost?), but for minikube it is returned by commany minikube ip.
2. Generally the applications require around 300-400 MB to start. There are 3 apps and Mongo, what gives us around 1.2 GB. Assuming it you can start minikube with minimum RAM requirement – 2gb. Of course you should also be able to run them on Kubernetes in Docker Desktop

I couldn’t find it on github and had to create it on my own.

Hello, I didn’t try to deploy on GKE. But it’s the standard Mongo template

Hello,
Although Spring Cloud Ribbon has been moved to the maintenance mode in the end of past year it is still the default client-side load balancer for all Spring Cloud projects. The development of Spring Cloud Loadbalancer is in progress, but I don’t think it has been finished yet. There is no any article about that, except my post on blog: https://piotrminkowski.wordpress.com/2019/04/05/the-future-of-spring-cloud-microservices-after-netflix-era/. If you need API gateway you can always use Kubernetes Ingress. In case you need Swagger API documentation you can probably use Spring Cloud Gateway. The only problem with that during writing this article was the lack of support for SpringFox Swagger project since Spring Cloud Gateway is based on asynchronous Netty server. However, I have already heard that this support has been implemented (I didn’t check it by myself).

I tried this example with Google Kubernetes Engine. When I am deploying mongodb on it, it is getting failed.
Error logs in mongo pod:
E QUERY [js] Error: couldn’t add user: Error preflighting normalization: U_STRINGPREP_PROHIBITED_ERROR :
_getErrorWithCode@src/mongo/shell/utils.js:25:13
DB.prototype.createUser@src/mongo/shell/db.js:1491:15
@(shell):1:1
Can you help me with this?

Do we still need to use the netflix api for ribbon and gateway? Or could we use spring cloud gateway and spring cloud load balancer?
Thanks
