设置PEP代理

我一直在研究PEP-Proxy-Steelskin,所以我可以为我的Orion Context提供一些安全层,但是,有一些问题阻碍了我的进展。

我想使用IDM和Keystone全局实例。

我已按照相应指示(https://github.com/telefonicaid/fiware-pep-steelskin)成功安装了pepProxy,但结果始终相同:

{
"name": "KEYSTONE_AUTHENTICATION_ERROR",
  "message": "There was a connection error while authenticating to Keystone: 500"
}

我在config.js文件中使用的配置如下所示:

var config = {};

// Protected Resource configuration
//--------------------------------------------------
// Configures the address of the component that is being proxied and the address of the proxy itself.
config.resource = {
    original: {
        /**
         * Host that is being proxied.
         */
        host: 'account.lab.fiware.org',

        /**
         * Port where the proxied server is listening.
         */
        port: 10026
    },

    proxy: {
        /**
         * Port where the proxy is listening to redirect requests.
         */
        port: 1026,

        /**
         * Administration port for the proxy.
         */
        adminPort: 11211
    }
};

// Access Control configuration
//--------------------------------------------------
/**
 * This options can be used to configure the address and options of the Access Control, responsible of the request
 * validation.
 */
config.access = {
    /**
     * Indicates whether the access control validation should be enabled. Defaults to false.
     */
    disable: false,

    /**
     * Protocol to use to access the Access Control.
     */
    protocol: 'http',
    /**
     * Host where the Access Control is located.
     */
    host: 'account.lab.fiware.org',
    /**
     * Port where the Access Control is listening.
     */
    port: 7070,
    /**
     * Path of the authentication action.
     */
    path: '/pdp/v3'
}

// User identity configuration
//--------------------------------------------------
/**
 * Information about the Identity Manager server from where the information about a user will be drawn.
 */
config.authentication = {
    checkHeaders: false,
    module: 'keystone',
    user: 'pep_proxy_99c595...',
    password: 'e3025a2...',
    domainName: 'matest',
    retries: 3,
    cacheTTLs: {
        users: 1000,
        projectIds: 1000,
        roles: 60,
        validation: 120
    },
    options: {
        protocol: 'http',
        host: 'cloud.lab.fiware.org',
        port: 5000,
        path: '/v3/role_assignments',
        authPath: '/v3/auth/tokens'
    }
};


// Security configuration
//--------------------------------------------------
config.ssl = {
    /**
     * This flag activates the HTTPS protocol in the server. The endpoint always listen to the indicated port
     * independently of the chosen protocol.
     */
    active: false,

    /**
     * Key file to use for codifying the HTTPS requests. Only mandatory when the flag active is true.
     */
    keyFile: '',

    /**
     * SSL Certificate to present to the clients. Only mandatory when the flag active is true.
     */
    certFile: ''
}

/**
 * Default log level. Can be one of: 'DEBUG', 'INFO', 'WARN', 'ERROR', 'FATAL'
 */
config.logLevel = 'FATAL';

// List of component middlewares
//-------------------------------------------------
/**
 * To validate the request, the proxy needs some information that is dependant of the component: the action that a
 * request is going to execute. How to detect the action given the request is component-specific logic, that can be
 * codified in a middleware-like function that will be executed before the user validation. This logic must populate
 * the 'action' parameter of the request.
 */
config.middlewares = {
    /**
     * Indicates the module from where the middlewares will be loaded.
     */
    require: 'lib/plugins/orionPlugin',

    /**
     * Indicates the list of middlewares to load.
     */
    functions: [
        'extractCBAction'
    ]
};

/**
 * If this flag is activated, whenever the pepProxy is not able to redirect a request, instead of returning a 501 error
 * (that is the default functionality) the PEP Proxy process will exit with a -2 code.
 */
config.dieOnRedirectError = false;

/**
 * Name of the component. It will be used in the generation of the FRN.
 */
config.componentName = 'orion';

/**
 * Prefix to use in the FRN (Not to change, usually).
 */
config.resourceNamePrefix = 'fiware:';

/**
 * Indicates whether this PEP should have an admin bypass or not. If it does, whenever a user request arrives to the
 * PEP from a user that has the role defined in the "adminRoleId" property, that request is not validated against the
 * Access Control, but it is automatically proxied instead.
 */
config.bypass = false;

/**
 * ID of the admin user if it exists. Only effective if the "bypass" property is true.
 */
config.bypassRoleId = '';

/**
 * Configures the maximum number of clients that can be simultaneously queued while waiting for the PEP to
 * authenticate itself against Keystone (due to an expired token).
 */
config.maxQueuedClients = 1000;

module.exports = config;

在此背景下:

  1. 使用account.lab.fiware.org作为资源和访问主机是否正确,还是应该使用其他主机?
  2. 使用cloud.lab.fiware.org作为身份验证主机是否正确?
  3. 用户和密码由我的IDM全球实例自动创建。角色和权限通过相同的全局实例分配。这个程序是否被挪用,或者我应该使用不同的程序?
  4. 我错过了什么吗?
  5. 有没有人对我的问题有任何暗示?

    注意:我已经尝试过不同的帖子并取得了成功。部分原因是因为其中许多解决方案都安装了自己的keystone,例如: PEP-Proxy-Steelskin Log configurationPEP proxy config file for integration of IDM GE, PEP proxy and Cosmos big dataPEP-Proxy-Steelskin Log configuration。这个是与我一直在做的事情更相关的那个,但我相信它不是最新的: Fiware Orion - pepProxy

我@netzahdzc抱歉,如果这不是您希望的回复,但我现在暂时不使用Fiware技术,所以我不记得所有内容,但我会尽力帮助。< / p>

  

使用account.lab.fiware.org作为资源和访问主机是否正确,还是应该使用不同的主机?

我认为你使用的是正确的,请参考GitHub项目的配置文件,这个项目是&#34; old&#34;所以有些事情可能已经从Fiware方面改变了......正如你在 PepProxy - config.js 中看到的那样,我使用的实例和你一样:

    config.account_host = 'https://account.lab.fiware.org';
    config.keystone_host = 'cloud.lab.fiware.org';
    config.keystone_port = 4730;
  

使用cloud.lab.fiware.org作为身份验证主机是否正确?

在我使用的配置(上图)中,您可以看到 account_host account.lab.fiware.org keystone_host (用于身份验证)是 cloud.lab.fiware.org ,所以我认为你是对的。

  

用户和密码由我的IDM Global Instance自动创建。角色和权限通过相同的全局实例分配。这个程序是否被挪用,或者我应该使用不同的程序?

我并没有深入研究这个问题但是对于回忆是的你是对的,角色和权限应该由Keystone全球实例处理,但我不知道自从我工作以来事情是否发生了变化有这个。

很抱歉,如果我无法提供更多帮助,请尝试查看您是否可以使用我的某些配置,或者至少它可以帮助您。您也可以尝试与Daniel Morán Jiménez交谈,我相信他可以帮助您更好地了解我。

答案 1 :(得分:0)

你的建议是否成功?

我认为如果你想使用IdM的全局实例,作为身份验证的身份提供者,你必须填充config.js值,如下面的代码片段所示,但我不确定它是否会发生工作。

// User identity configuration
//--------------------------------------------------
/**
 * Information about the Identity Manager server from where the information about a user will be drawn.
 */
config.authentication = {
    checkHeaders: true,
    module: 'keystone',
    user: 'pep_proxy_1234...',
    password: 'my-autogenerated-password',
    domainName: 'Default',
    retries: 3,
    cacheTTLs: {
        users: 1000,
        projectIds: 1000,
        roles: 60,
        validation: 120
    },
    options: {
        protocol: 'http',
        host: 'cloud.lab.fiware.org',
        port: 4730,
        path: '/v3/role_assignments',
        authPath: '/v3/auth/tokens'
    }
};

当然,请将字段用户密码替换为值 由IDM Global Instance自动创建。

但是,我认为您应该使用PEP代理GE(Wilma PEP Proxy)的参考实现,以防您仍想使用Fiware Cloud的全局实例。

您正在使用Telefonica implementation of this GE,从我的观点来看,它与Wilma存在一些差异,我不能100%确定它是否可以与IdM Keyrock和{{3的参考实现集成使用Authorization PDP Authzforce的全局实例。

一种完全不同的方法,可能是使用您自己的IdM,PDP授权和PEP代理通用启动器(GE)实例。在这种情况下,您仍然可以使用这三个组件的引用实现,或者您可以使用Steelskin PEP代理。如果您遵循Steelskin路径,我建议您使用Fiware CloudKeystone-spassword,它们分别是Telefonica对IdM和授权PDP的实现。 Keypass您可以逐步了解如何安装和配置此GE。

最后,如果你想要遵循“参考”GE路径,你可以在Here找到一些亮点。
