In the context of Netflix Zuul, which is a gateway service used to route requests to different microservices, the `zuul.ignored-services` property is used to specify which services should be ignored by the Zuul proxy. When you set `zuul.ignored-services = *`, it means that all services will be ignored by default. Here's what this configuration does: 1. Ignore All Services: By setting `zuul.ignored-services = *`, you are telling Zuul to ignore all services. This means that no routes will be automatically created for any services. 2. Manual Route Configuration: If you want to route specific services, you will need to define them manually using the `zuul.routes` property. For example: ```yaml zuul: ignored-services: '*' routes: service1: path: /service1/ serviceId: service1 service2: path: /service2/ serviceId: service2 ``` 3. Control Over Routes: This configuration gives you more control over which services are routed through Zuul. It ensures that only the explicitly defined routes are available. Example Configuration Here is an example of how you might configure Zuul with `zuul.ignored-services = *` and manually define routes: ```yaml zuul: ignored-services: '*' routes: userservice: path: /users/ serviceId: user-service productservice: path: /products/ serviceId: product-service ``` Explanation - ignored-services: '*': This tells Zuul to ignore all services by default. - routes: This section defines the specific routes that you want to include. Each route specifies a path and the corresponding service ID. Benefits - Security: By ignoring all services by default, you reduce the risk of unintended services being exposed. - Flexibility: You can precisely control which services are accessible through the gateway. Drawbacks - Configuration Overhead: You need to manually configure each route, which can be more work if you have many services. By using `zuul.ignored-services = *`, you ensure that only the services you explicitly define are routed through Zuul, providing better control and security for your microservices architecture.
