我正在努力将我们现有的 docker 容器迁移到 openshift 中，并且在尝试将我们的 2 个容器放入一个 pod 时遇到了问题。我们将 Spring Cloud Config Server 用于我们的服务，并带有 Gitea 后端。我想将它们放在一个 pod 中，以便 java 服务器和 git 服务器总是捆绑在一起。
我可以通过关联的路由单独访问每个容器，但配置服务器无法访问 git 服务器，反之亦然。当配置服务器尝试克隆 git 存储库时，我得到 404。我尝试过使用 gitea-${INSTANCE_IDENTIFIER}（INSTANCE_IDENTIFIER 只是一个生成的值，可以一目了然地将所有对象联系在一起）、gitea-${INSTANCE_IDENTIFIER}.myproject.svc 和 gitea-${INSTANCE_IDENTIFIER}.myproject .svc.cluster.local，以及创建的路由的完整 url，但没有任何效果。
这是我的模板，为了安全起见，删除了一些东西（...）：
