如何在多个端口上公开我的Hasura微服务?

我的微服务有多个容器,每个容器都需要访问不同的端口。如何使用Hasura CLI和项目配置文件在多个端口上公开此服务?

编辑:添加微服务的k8s.yaml(根据@iamnat的要求) 假设我有两个容器containerAcontainerB,我希望分别在端口63798000上通过HTTP公开。

    - port: 8000

TL; DR: - 为要公开的每个HTTP端点添加API网关路由[docs]

在kubernetes集群内,给你的k8s规格这就是你的设置:

http://www.default:8000  -> containerA
http://www.default:6379  -> containerB

因此,您需要为conf/routes.yaml中的每个HTTP路径创建路由。

www-a:
  /:
    upstreamService:
      name: www
      namespace: {{ cluster.metadata.namespaces.user }}
    upstreamServicePath: /
    upstreamServicePort: 8000
    corsPolicy: allow_all
www-b:
  /:
    upstreamService:
      name: www
      namespace: {{ cluster.metadata.namespaces.user }}
    upstreamServicePath: /
    upstreamServicePort: 6379
    corsPolicy: allow_all

这意味着,您将获得以下内容:

https://www-a.domain.com -> containerA
https://www-a.domain.com -> containerB
