<h1 id="工具由来"><a href="#工具由来" class="headerlink" title="工具由来"></a>工具由来</h1><p>为什么要写这样的一个工具呢？这是因为我司有多个 <code>kubernetes</code> 集群(8+)，且都是云托管服务无法接触到Apiserver配置，这就给我们带来一个痛点，<strong>开发、sre需要登录k8s dashbaord且不同部门和角色间需要不同的授权</strong>，原先都是通过 <code>sa token</code> 进行登录dashboard，但随着k8s集群的增长，每增加一个集群，就需要告知使用方对应dashboard访问地址以及对应的token，这不管是提供方还是使用方都让人感觉非常的痛苦。那是否有一款工具能<strong>提供统一地址统一登录多集群dashboard的方案</strong>呢？经过一番搜索后，发现并没有，市面上大多数是单集群集成 <code>LDAP</code> 的方案，主要是以 <code>DEX</code> 为主，但光单集群的统一登录授权方案就让人感觉非常的困难。难道就没有简单方便的工具供我们使用吗？好吧，那我就来打造这样一款工具吧。</p>
<p>Dashboard LDAP集成方案：</p>
<ul>
<li><a href="https://k2r2bai.com/2019/09/29/ironman2020/day14/" target="_blank" rel="external">https://k2r2bai.com/2019/09/29/ironman2020/day14/</a></li>
<li><a href="https://blog.inkubate.io/access-your-kubernetes-cluster-with-your-active-directory-credentials" target="_blank" rel="external">https://blog.inkubate.io/access-your-kubernetes-cluster-with-your-active-directory-credentials</a></li>
</ul>
<p>以上两篇文档是成LDAP的方案，个人感觉还不错，供有需要的人参考！<br><a id="more"></a></p>
<h1 id="如何打造"><a href="#如何打造" class="headerlink" title="如何打造"></a>如何打造</h1><p>好吧既然没有，那就自动动手打造一个！</p>
<blockquote>
<p>目标： <strong>简单使用</strong>！！！通过访问同一地址，使用LDAP登录且可切换不同集群的dashboard，同时对应不同的集群权限可单独配置！</p>
</blockquote>
<p>有了上面的目标，那如何来实现呢？</p>
<p>实现方式其实很简单，首先写一个登录界面与公司的AD进行打通获取用户与组，然后将用户或者组与k8s集群中的 <code>service account</code> 进行关联就实现了对应的rbac与登录token，最后在登录后实现一个反向代理服务即可完成。</p>
<p>是不是非常的简单！！！</p>
<p>实现技术栈：golang(gin、client-go、viper、ldap) + Kubernetes Dashboard</p>
<h1 id="如何部署"><a href="#如何部署" class="headerlink" title="如何部署"></a>如何部署</h1><h2 id="前提条件"><a href="#前提条件" class="headerlink" title="前提条件"></a>前提条件</h2><p>在使用此工具前，需要有以下一些条件约束：</p>
<ol>
<li>已在各k8s集群部署 <code>dashboard</code> 且能被此工具访问到</li>
<li>已有 <code>ldap</code> 且有管理权限能进行访问操作</li>
<li>各集群中有对应的 <code>service account</code> 可进行映射，如需对不同用户和组需要有不同的操作权限，则对sa进行rbac授权即可，下面会详细说明。</li>
<li>此工具需要操作各集群的api，故需要获取每个集群的 <code>apiserver地址</code>、<code>ca.crt</code> 以及 <code>token</code> 进行配置，至于每个集群的 <code>ca.crt</code> 和 <code>token</code> 如果获取，后面会进行说明</li>
</ol>
<h2 id="如何获取-ca-crt-及-token"><a href="#如何获取-ca-crt-及-token" class="headerlink" title="如何获取 ca.crt 及 token"></a>如何获取 ca.crt 及 token</h2><p>此工具需要操作每个集群的api来获取对应的 sa 以及 token，故需要有对各集群操作的权限。那如何在各集群生成对应的 ca证书 及 token 呢？答案就是创建一个 sa 并给予一定的权限。</p>
