Springcloud First experience: Five, Sidecar the PHP non-Java language services to the Spring Cloud

Start with a Sidecar service, a PHP service, an application, and PHP services deployed on the same machine, accessed through localhost, which solves the network overhead, equivalent to the local inter-process call

Sidecar service is relatively simple,

2, sidecar related configuration, and the configuration of the registration center

 
Spring:
   Application:
     Name: tx-php-server-sidecar

Service registry port number
Server:
   Port: 8203

#Hostname and port of the service registry instance
#Do you register yourself with the service registry?
#Whether to retrieve the service
#Configuration of the registration center, specify the location of the service registry
Eureka:
   Port: 8200
   Instance:
     Hostname: localhost
   Client:
     Register-with-eureka: true
     Fetch-registry: true
     serviceUrl:
       defaultZone: http://${eureka.instance.hostname}:${eureka.port}/eureka/

Sidecar:
   Port: 1215
   Instance:
     Hostname: localhost
   Health-uri: http://${sidecar.instance.hostname}:${sidecar.port}/health

3. Service startup class @EnableSidecar

4, also need in PHP service a check service interface or file, note the response header type Content-type

Take the Laravel framework as an example, the configured address is Http://127.0.0.1:1215/health

 
Route::get(‘health‘, function () {
    $content = ‘{ "status" : "UP" }‘;
    $status = 200;
    $value = ‘application/json; charset=utf-8‘;
    return response($content, $status)
        ->header(‘Content-Type‘, $value);
});

This is through the Eureka Center page, see Sidecar has been registered, note if the PHP Health page response content or response header is incorrect, the Sidecar service's up status will show down

This is the default page for PHP services

This is the PHP service page that was forwarded via Spring Cloud Gateway
