问题 I am currently creating a new application based on a Microservices architecture, with authentication provided by Identity Server 4. Following lots of research and also setting up proof of concepts, I have Identity Server setup to secure the API's and a native application successfully accessing these services using tokens. Initially the client was issued an access token which was used to access the API's, I have however now switched this out to use reference tokens. Now, onto the issue! The

问题 I'm using Jhipster 5.5.0 to build a zuul gateway capable to route rest request to different microservices. Some of this microservices are developed in different languages, deployed and running on different server. Every microservices is protected via OIDC using the same keycloak server, under different realms. Now I need to configure zuul route on application.yml properties file of my gateway app, to access this service by external rest client (customers) and using zuul for filtering request

问题 Need some serious help here ! Thanks in advance. I am trying to deploy a microservice based Java application.

问题 Not sure if this is the right place, please point me to a different forum if not. In a multi-cluster kubernetes setup, is cross-cluster communication a valid design? In particular, a pod in one cluster relying on a pod in another cluster. Or are there limitations or anti-patterns associated with this that we should avoid? If not, what tools do you use to manage this deployment and monitor load on each cluster? 回答1: Multicluster deployments give you a greater degree of isolation and

问题 I am implementing a spring-boot microservice for elasticsearch (es) operations using springdata APIs. My documents that are indexed in es are huge with multiple fields (more than 100).

My sample patient JSON could be like: { "key_1":"value_1", "key_2":"value_2", "key_3":"value_3", . . . "key_n":"value_n" } 回答1: If you can go for a slightly different form to store your data in

问题 My project has over 30 microservices and 20 over private scope npm packages (4 teams working on these microservices). We are following those microservice best practices like DRY principles. However, we realized that there are a few issue within that we are unable to control well. The management of private npm version. e.g upgrade our private package version in our microservices. Circular dependencies between the private packages. Due to that, our microservices always build and deployment
