<p>Dockerfile中从远程获取zookeeper的安装文件，然后在定义了三个脚本：</p>

|
<p>我们再主要下上面那三个脚本的用途。</p>
|
||
|
|
<h2 id="部署kafka">部署kafka</h2>
|
||
|
|
<p>Kafka的docker镜像制作跟zookeeper类似，都是从远程下载安装包后，解压安装。</p>
|
||
|
|
<p>与zookeeper不同的是，只要一个脚本，但是又依赖于我们上一步安装的zookeeper，kafkaGenConfig.sh用来生成kafka的配置文件。</p>
|
||
|
|
<p>我们来看下这个脚本。</p>
|
||
|
|
<pre><code class="lang-bash"><span class="hljs-meta">#!/bin/bash</span>

|

<p>该脚本根据statefulset生成的pod的hostname的后半截数字部分作为broker ID，同时再替换zookeeper的地址。</p>
