问题描述

我在docker容器中同时运行Spring Boot和Keycloak时遇到问题.

我从Keycloak开始，它以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，我在Spring-boot-application中添加了spring-security.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SpringBoot-Application运行正常. 我必须使用keycloak登录并重定向到localhost:8090. 但是，当我将SpringBoot-Application添加到我的docker-compose并在容器中启动它时，我仍然到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:

我不知道该怎么解决...

更多信息:我正在Windows上运行docker.

解决方案

我的工作解决方案包含以下内容:

  1. 步骤，将密钥斗篷添加为主机

要使一切正常运行，您需要确保将以下内容添加到主机文件(在Mac/Linux上为/etc/hosts，在Windows上为c:\ Windows \ System32 \ Drivers \ etc \ hosts). /p>

127.0.0.1密钥斗篷

这是因为您将使用计算机上的浏览器(名称为localhost或127.0.0.1)访问应用程序，但是在Docker内部它将在自己的容器中运行，该容器的名称为keycloak.

  1. 步骤

内部Docker端口和发布的端口必须相同:

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中用于Spring Boot的keycloak定义编辑了auth-server-url:

    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

此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 我花了大量时间测试其他组合，结果访问URL端口必须与内部docker端口相同(在我的情况下为8080).

相同的东西在Thorntail中起作用.

要更改Keycloak的端口，请添加... 

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中的密钥斗篷. -Djboss.socket.binding.port-offset = 10设置默认端口(8080)+偏移(10) 其余的是keycloak的默认值. 不要忘记编辑端口"和"auth-server-url"

解决方案

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

在容器内部，它必须是容器的名称，即keycloak.这有点尴尬，因为当您从主机连接到keycloak时，您想使用localhost，但是令牌发行者的URL需要与请求令牌的URL匹配(否则令牌被拒绝)，因此您最终不得不将keycloak放入您的etc/hosts文件中.

您在这个问题上表现得很好-我遇到了这个 JHipster项目以相同的方式处理-他们说:

要使其正常运行，您需要确保将以下内容添加到主机文件中(在Mac/Linux中为/etc/hosts，在Windows中为c:\Windows\System32\Drivers\etc\hosts).

127.0.0.1 keycloak

这是因为您将使用计算机上的浏览器(名称为localhost或127.0.0.1)访问应用程序，但是在Docker内部它将在自己的容器中运行，该容器的名称为keycloak.

i have a Problem Running Spring Boot and Keycloak both in docker containers.

I started with Keycloak with mysql as db running in docker.

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

Then i added my realm (SpringBootKeycloak), my client (testclient), and a user with role 'user'. After that i added spring-security to my Spring-boot-application. And edited my 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

accoring to that i added my 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();
  }

Running my SpringBoot-Application locally is working fine. I have to login with keycloak and get redirected to localhost:8090. But when i add my SpringBoot-Application to my docker-compose and start it in a container i get still to keycloak for login, but when i should redirect i get a 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

with following container log:

I can't figure out how to solve this...

EDIT 1: One more information: I'm running docker on Windows.

EDIT 2: A SOLUTION

My Working solution contains following:

  1. Step, add keycloak as hosts

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. Step

Inner Docker port and published port needs to be same:

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

Step 3: keycloak definition in application.yml for Spring boot edited auth-server-url:

    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

The ugly thing coming with this solution: You cant map your Docker Port onto another port to access from url. ports: - 8080:8080 i spend a lot of time testing other combinations, with the result that the access url port has to be the same as inner docker port (8080 in my case).

EDIT 4:

Same thing is working with Thorntail.

To change the port for Keycloak add...

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"

... for keycloak in docker-compose. -Djboss.socket.binding.port-offset=10 sets default port (8080) + offset (10) The rest are default values for keycloak. Don't forget to edit "ports" and "auth-server-url"

解决方案

I think your problem is auth-server-url: http://localhost:8180/auth. That localhost effectively has a different meaning when your app is running inside a docker container.

Inside the container it needs to be the name of the container i.e. keycloak. This is a bit awkward as when you connect to keycloak from your host machine you'd want to use localhost but the token issuer url needs to match to the url on which the token was requested (otherwise the token is rejected) so you end up having to put keycloak into your etc/hosts file.

You are in good company with this problem - I've encountered this working with Activiti. And you can find the JHipster project dealing with it in the same way - they say:

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.
