<h1>Docker top 命令</h1>
|
||
<p><strong>docker top :</strong>查看容器中运行的进程信息，支持 ps 命令参数。</p>
|
||
<h3>语法</h3>
|
||
<pre><code class="language-Docker">docker top [OPTIONS] CONTAINER [ps OPTIONS]</code></pre>
|
||
<p>容器运行时不一定有/bin/bash终端来交互执行top命令，而且容器还不一定有top命令，可以使用docker top来实现查看container中正在运行的进程。</p>
|
||
<h3>实例</h3>
|
||
<p>查看容器mymysql的进程信息。</p>
|
||
<pre><code class="language-Docker">runoob@runoob:~/mysql$ docker top mymysql
|
||
|
||
UID PID PPID C STIME TTY TIME CMD
|
||
|

999 40347 40331 18 00:58 ? 00:00:02 mysqld
|

</code></pre>
|
||
<pre><code class="language-Docker">for i in `docker ps |grep Up|awk '{print $1}'`;do echo \ &&docker top $i; done</code></pre>
