|

|
|
<p><code>kubernetes</code> 系统的各组件需要使用 <code>TLS</code> 证书对通信进行加密，本文档使用 <code>CloudFlare</code> 的 PKI 工具集 <a href="https://github.com/cloudflare/cfssl" target="_blank">cfssl</a> 来生成 Certificate Authority (CA) 和其它证书；</p>
|
||
|
|
<p><strong>生成的 CA 证书和秘钥文件如下：</strong></p>
|
||
|
|
<ul>
|
||
|
|
<li>ca-key.pem</li>
|
||
|
|
<li>ca.pem</li>
|
||
|
|
<li>kubernetes-key.pem</li>
|
||
|
|
<li>kubernetes.pem</li>
|
||
|
|
<li>kube-proxy.pem</li>
|
||
|
|
<li>kube-proxy-key.pem</li>
|
||
|
|
<li>admin.pem</li>
|
||
|
|
<li>admin-key.pem</li>
|
||
|
|
</ul>
|
||
|
|
<p><strong>使用证书的组件如下：</strong></p>
|
||
|
|
<ul>
|
||
|
|
<li>etcd：使用 ca.pem、kubernetes-key.pem、kubernetes.pem；</li>
|
||
|
|
<li>kube-apiserver：使用 ca.pem、kubernetes-key.pem、kubernetes.pem；</li>
|
||
|
|
<li>kubelet：使用 ca.pem；</li>
|
||
|
|
<li>kube-proxy：使用 ca.pem、kube-proxy-key.pem、kube-proxy.pem；</li>
|
||
|
|
<li>kubectl：使用 ca.pem、admin-key.pem、admin.pem；</li>
|
||
|
|
</ul>
|
||
|
|
<p><code>kube-controller</code>、<code>kube-scheduler</code> 当前需要和 <code>kube-apiserver</code> 部署在同一台机器上且使用非安全端口通信，故不需要证书。</p>

<p><strong>方式二：使用go命令安装</strong></p>

<p>我们的系统中安装了Go1.7.5，使用以下命令安装更快捷：</p>
|
||
|
|
<pre><code>$go get -u github.com/cloudflare/cfssl/cmd/...
|

|
|
$echo $GOPATH
|

/usr/local
|

|
$ls /usr/local/bin/cfssl*
|

|
|
cfssl cfssl-bundle cfssl-certinfo cfssljson cfssl-newkey cfssl-scan
|
