Great job as usual bro, thank you. Could you also make an overall video about docker and kubernetes operations on spring boot microservices

Good video. Need sessions on how to store the users and their roles and permissions to DB and maintain the hierarchy.

I really appreciate for this tutorials. This is a very good video to learn keycloak. Can we get an video on how to secure distributed services like
Angular -> Service A -> Service B
Here -> mean calls.
And can you add authorization in that video? Thank you.

When I wrote localhost:8080/home, it took me to a page: localhost:8080/login that said Login with OAuth 2.0. I did not have the same page open as at 21:16

[manee]

In the case of the Angular App, why is there no client secret?
I mean, if I get the url of an authorization server (issuer url) and a valid clientId, I can also build a client application using/calling that same authorization server (with its users, realms etc.).
How then could we prevent that?
Most important: Thanks a lot for the informative videos.

Why have you used Spring WebFlux and not simple Spring MVC for this project? As this project does not need to handle asynchronous requests?? Anyone knows can answer please..

[Ben-vzzm]

How do i make it so that certain thymeleaf pages don't require a login?

[muhammedSafeer-gzeq]

If we go to some websites, we can see options to login via OAuth2 and also using normal username and password. Now that I understand OAuth2, can I use OAuth2 for (Basic Auth) username-password authentication?

[karthikeyanrm]

Excellent Video Sai. Can you please let us know if you would make that complex Microservices course along with Cloud and Angular even if it's a paid one ?

[michaelkg]

Thanks a lot. Very interesting and useful information. But what if I have a rest application. And I shouldn't redirect user to a login page. How I should configure my app in that case

Hi great tutorial, just liked and subscribed. Could you please develop a full stack tinder clone? I think that would be a very unique Spring Boot application. Otherwise your Youtube Clone video is excellent and unique
