密钥斗篷适配器在将 Springboot Webapp 部署到 Docker 时无法验证令牌

Question

我正在开发一个在Tomcat上运行的Springboot应用程序和React前端，以及Hasura Graphql和Keycloak。所有 3 个项目都在一个 Docker 堆栈中运行，具有以下 stack.yml：

version: '3.7'

services:
  timescale-primary:
    image: timescale-replication:latest
    env_file:
      - primary.env
    networks:
      - public-network
    ports:
      - 5432:5432
    volumes:
      - timescale-primary-storage:/var/lib/postgresql/data
    deploy:
      placement:
        constraints:
          - node.labels.type == primary

  timescale-replica:
    image: timescale-replication:latest
    env_file:
      - replica.env
    networks:
      - public-network
    volumes:
      - timescale-replica-storage:/var/lib/postgresql/data
    deploy:
      placement:
        constraints:
          - node.labels.type != primary

  hasura:
    image: hasura/graphql-engine
    networks:
      - public-network
    ports:
      - 6080:8080
    env_file:
      - hasura.env
    volumes:
      - hasura-storage:/var/lib/hasura
    depends_on:
      - timescale-primary

  keycloak:
    image: keycloak
    networks:
      - public-network
    ports:
      - 9080:8080
    env_file:
      - keycloak.env
    volumes:
      - keycloak-storage:/opt/jboss/keycloak/themes
    depends_on:
      - timescale-primary

  tomcat:
    image: tomcat:v1
    networks:
      - public-network
    ports:
      - 8086:8080
    volumes:
      - tomcat-storage:/usr/local/tomcat/webapps:Z
      - tomcat-log-storage:/var/log/tomcat:Y

networks:
  public-network:

volumes:
  timescale-primary-storage:
  timescale-replica-storage:
  hasura-storage:
  keycloak-storage:
  tomcat-storage:
  tomcat-log-storage:

SpringBoot webapp是一个运行在http://tomcat:8080/backend，并且React应用程序部署在http://tomcat:8080/ui.

在Hasura中，我设置了一个指向该服务器的远程模式：超文本传输协议：//tomcat： 8080/backend/graph ql，并转发了所有客户端标头。

基本上，React 应用程序通过 Hasura 间接访问“后端”。

在Keycloak中，我为“ui”应用程序设置了一个公共客户端，为“后端”应用程序设置了一个机密客户端。

然后，我得到身份验证流程，如下所示：

1. 在 Docker 的主机上，调用 http://localhost:8086/ui
2. 转发到本地主机：9080/身份验证/...（钥匙斗篷的登录屏幕）
3. 登录成功后，重定向到“ui”应用
4. React 应用程序调用 Hasura
5. Hasura 调用“后端”并获取“验证令牌失败”、“授权标头无效，有关详细信息，请参阅 WWW-身份验证标头”

如果我把React和Springboot应用程序放在一个直接安装在Docker主机上的Tomcat中，后端的认证就没问题了。只有当所有东西都部署到Docker中时，才会出现此问题。

我是Keycloak和Docker的新手，感谢任何帮助。

Answer 1

为了使身份验证工作，React应用程序和springboot应用程序的Keycloak URL需要相同。也就是说，您不能对一个使用localhost，而对另一个使用Docker容器名称。

在我的情况下，可以使用公共IP或实际域名。
