Spring Cloud for Tanzu Application Service (TAS)

First we need to create manifest.yml for every project which go into TAS

For this example we are using java-buildpack.

---
applications:
  - name: gw 
    buildpack: https://github.com/cloudfoundry/java-buildpack.git#v4.48.2
    instances: 1
    memory: 512M
    env:
      SPRING_PROFILES_ACTIVE: cloud
      JAVA_OPTS: -Xms256m -Xmx256m -Xss64m
      JBP_CONFIG_OPEN_JDK_JRE: '{ jre: { version: 11.+}}'
      JBP_CONFIG_SPRING_AUTO_RECONFIGURATION: '{enabled: false}'

URL base routing

In project gw

@Bean
public RouteLocator MyRoute(RouteLocatorBuilder builder) {
    return builder//
            .routes()//
            .route("svc1", r -> r.path("/svc1/**")
                    //
                    .filters(f -> f.stripPrefix(1))
                    //
                    .uri("lb://svc1"))//
            .route("svc2", r -> r.path("/svc2/**")
                    //
                    .filters(f -> f.filter(authFilter).stripPrefix(1))
                    //
                    .uri("lb://svc2"))//
            .build();
}
