java - Docker(Spring Boot 或 Thorntail)和 Keycloak

Question

我在 docker 容器中运行 Spring Boot 和 Keycloak 时遇到问题。

我开始使用 Keycloak，mysql 作为 db 在 docker 中运行。

services:
  mysql:
    image: mysql:5.7
    container_name: mysql
    volumes:
      - mysql_data:/var/lib/mysql
    environment:
      MYSQL_ROOT_PASSWORD: root
      MYSQL_DATABASE: keycloak
      MYSQL_USER: keycloak
      MYSQL_PASSWORD: password
    networks:
      - testNetwork

  keycloak:
    image: jboss/keycloak
    container_name: keycloak
    restart: on-failure
    volumes:
      - ./config:/config/
    environment:
      DB_VENDOR: MYSQL
      DB_ADDR: mysql
      DB_DATABASE: keycloak
      DB_USER: keycloak
      DB_PASSWORD: password
      KEYCLOAK_USER: xxx
      KEYCLOAK_PASSWORD: yyy
      KEYCLOAK_IMPORT_REALM: /keycloak/import/realm-import.json
    ports:
      - 8180:8080
    depends_on:
      - mysql
    networks:
      - testNetwork

然后我添加了我的领域 (SpringBootKeycloak)、我的客户端 (testclient) 和一个角色为“user”的用户。之后，我将 spring-security 添加到我的 Spring-boot-application 中。并编辑了我的 application.yml

spring:
  main:
    banner-mode: 'off'
  application:
    name: testclient
    version: @project.version@
  jpa:
    hibernate:
      ddl-auto: create
  datasource:
    url: jdbc:h2:mem:testclient;DB_CLOSE_DELAY=-1;DB_CLOSE_ON_EXIT=FALSE
    username: xxx
    password: xxx
keycloak:
  auth-server-url: http://localhost:8180/auth
  realm: SpringBootKeycloak
  resource: testclient
  public-client: true
  principal-attribute: preferred_username
  security-constraints:
    - authRoles:
      - user
      securityCollections:
        - patterns:
          - /*
server:
  port: ${port:8090}
  rest:
    path: testclient

据此我添加了我的 SecurityConfig:

  /**
   * Secure appropriate endpoints
   */
  @Override
  protected void configure(HttpSecurity http) throws Exception {
    super.configure(http);
    http.authorizeRequests()
        .antMatchers("/*").hasRole("user") // only user with role user are allowed to access
        .anyRequest().permitAll();
  }

在本地运行我的 SpringBoot 应用程序工作正常。我必须使用 keycloak 登录并重定向到 localhost:8090。但是当我将我的 SpringBoot-Application 添加到我的 docker-compose 并在容器中启动它时，我仍然使用 keycloak 进行登录，但是当我应该重定向时，我得到了 403。

  testclient:
    image: testclient
    container_name: testclient
    environment:
      JAVA_OPTS: "-agentlib:jdwp=transport=dt_socket,address=5005,server=y,suspend=n"
    build:
      context: testclient-application
    ports:
      - 8090:8090
      - 5006:5005
    networks:
      - testNetwork

具有以下容器日志:

我想不出如何解决这个...

编辑 1:更多信息:我在 Windows 上运行 docker。

编辑 2:解决方案

我的工作解决方案包含以下内容:

1. 步骤，添加 keycloak 作为主机

To make things work, you’ll need to make sure to add the following to your hosts file (/etc/hosts on Mac/Linux, c:\Windows\System32\Drivers\etc\hosts on Windows).

127.0.0.1 keycloak

This is because you will access your application with a browser on your machine (which name is localhost, or 127.0.0.1), but inside Docker it will run in its own container, which name is keycloak.

1. 步骤

内部 Docker 端口和发布的端口需要相同:

services:
  mysql:
    image: mysql:5.7
    container_name: mysql
    volumes:
      - mysql_data:/var/lib/mysql
    environment:
      MYSQL_ROOT_PASSWORD: root
      MYSQL_DATABASE: keycloak
      MYSQL_USER: keycloak
      MYSQL_PASSWORD: password
    networks:
      - testNetwork

  keycloak:
    image: jboss/keycloak
    container_name: keycloak
    restart: on-failure
    volumes:
      - ./config:/config/
    environment:
      DB_VENDOR: MYSQL
      DB_ADDR: mysql
      DB_DATABASE: keycloak
      DB_USER: keycloak
      DB_PASSWORD: password
      KEYCLOAK_USER: xxx
      KEYCLOAK_PASSWORD: yyy
      KEYCLOAK_IMPORT_REALM: /keycloak/import/realm-import.json
    ports:
      - 8080:8080   <--- edited
    depends_on:
      - mysql
    networks:
      - testNetwork

第 3 步:在 application.yml 中为 Spring boot 编辑的 auth-server-url 中的 keycloak 定义:

    keycloak:
  realm: SpringBootKeycloak
  auth-server-url: http://keycloak:8080/auth   <--- edited
  resource: testclient
  public-client: true
  security-constraints:
    - authRoles:
      - user
      securityCollections:
        - patterns:
          - /*
  ssl-required: external
  confidential-port: 0

这个解决方案带来的丑陋之处:您无法将 Docker 端口映射到另一个端口以从 url 访问。 端口: - 8080:8080我花了很多时间测试其他组合，结果是访问 url 端口必须与内部 docker 端口(在我的例子中是 8080)相同。

编辑 4:

同样的事情也适用于 Thorntail。

要更改 Keycloak 添加的端口...

environment:
  JAVA_OPTS: "-Djboss.socket.binding.port-offset=10 -Xms64m -Xmx512m -XX:MetaspaceSize=96M -XX:MaxMetaspaceSize=256m
  -Djava.net.preferIPv4Stack=true -Djboss.modules.system.pkgs=org.jboss.byteman -Djava.awt.headless=true"

... 用于 docker-compose 中的 keycloak。-Djboss.socket.binding.port-offset=10 设置默认端口(8080)+偏移量(10)其余的是 keycloak 的默认值。不要忘记编辑“ports”和“auth-server-url”

Answer 1

我认为您的问题是 auth-server-url: http://localhost:8180/auth。当您的应用程序在 docker 容器内运行时，localhost 实际上具有不同的含义。

在容器内部，它需要是容器的名称，即 keycloak。这有点尴尬，因为当您从主机连接到 keycloak 时，您想要使用 localhost 但 token 发行者 url 需要与请求 token 的 url 匹配(否则 token 被拒绝)所以你最终不得不将 keycloak 放入你的 etc/hosts 文件中。

你在这个问题上很好 - 我遇到过这个 working with Activiti .你可以找到 JHipster project dealing with it in the same way - 他们说:

To make things work, you’ll need to make sure to add the following to your hosts file (/etc/hosts on Mac/Linux, c:\Windows\System32\Drivers\etc\hosts on Windows).

127.0.0.1 keycloak

This is because you will access your application with a browser on your machine (which name is localhost, or 127.0.0.1), but inside Docker it will run in its own container, which name is keycloak.
