|
||
|
<p>对于没有使用过 kubernetes 的 docker 用户,如何快速掌握 kubectl 命令?</p>
|
||
|
<p>在本文中,我们将向 docker-cli 用户介绍 Kubernetes 命令行如何与 api 进行交互。该命令行工具——kubectl,被设计成 docker-cli 用户所熟悉的样子,但是它们之间又存在一些必要的差异。该文档将向您展示每个 docker 子命令和 kubectl 与其等效的命令。</p>
|
||
|
<p>在使用 kubernetes 集群的时候,docker 命令通常情况是不需要用到的,只有在调试程序或者容器的时候用到,我们基本上使用 kubectl 命令即可,所以在操作 kubernetes 的时候我们抛弃原先使用 docker 时的一些观念。</p>

<h4 id="docker-run">docker run</h4>
|
||
|
<p>如何运行一个 nginx Deployment 并将其暴露出来? 查看 <a href="https://kubernetes.io/docs/user-guide/kubectl/#run" target="_blank">kubectl run</a> 。</p>
|
||
|
<p>使用 docker 命令:</p>
|
||
|
<pre><code class="lang-bash">$ docker run <span class="hljs-_">-d</span> --restart=always <span class="hljs-_">-e</span> DOMAIN=cluster --name nginx-app -p 80:80 nginx
|
||
|
a9ec34d9878748d2f33dc20cb25c714ff21da8d40558b45bfaec9955859075d0
|
||
|
$ docker ps
|
||
|
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
|
||
|
a9ec34d98787 nginx <span class="hljs-string">"nginx -g 'daemon of 2 seconds ago Up 2 seconds 0.0.0.0:80->80/tcp, 443/tcp nginx-app
|
||
|
</span></code></pre>
|
||
|
<p>使用 kubectl 命令:</p>
|
||
|
<pre><code class="lang-bash"><span class="hljs-comment"># start the pod running nginx</span>
|
||
|
$ kubectl run --image=nginx nginx-app --port=80 --env=<span class="hljs-string">"DOMAIN=cluster"</span>
|
||
|
deployment <span class="hljs-string">"nginx-app"</span> created
|
||
|
</code></pre>
|
||
|
<p>在大于等于 1.2 版本 Kubernetes 集群中,使用<code>kubectl run</code> 命令将创建一个名为 "nginx-app" 的 Deployment。如果您运行的是老版本,将会创建一个 replication controller。 如果您想沿用旧的行为,使用 <code>--generation=run/v1</code> 参数,这样就会创建 replication controller。查看 <a href="https://kubernetes.io/docs/user-guide/kubectl/#run" target="_blank"><code>kubectl run</code></a> 获取更多详细信息。</p>
|
||
|
<pre><code class="lang-bash"><span class="hljs-comment"># expose a port through with a service</span>
|
||
|
$ kubectl expose deployment nginx-app --port=80 --name=nginx-http
|
||
|
service <span class="hljs-string">"nginx-http"</span> exposed
|
||
|
</code></pre>
|
||
|
<p>在 kubectl 命令中,我们创建了一个 <a href="https://kubernetes.io/docs/concepts/workloads/controllers/deployment" target="_blank">Deployment</a>,这将保证有 N 个运行 nginx 的 pod(N 代表 spec 中声明的 replica 数,默认为 1)。我们还创建了一个 <a href="https://kubernetes.io/docs/user-guide/services" target="_blank">service</a>,使用 selector 匹配具有相应的 selector 的 Deployment。查看 <a href="https://kubernetes.io/docs/user-guide/quick-start" target="_blank">快速开始</a> 获取更多信息。</p>
|
||
|
<p>默认情况下镜像会在后台运行,与<code>docker run -d ...</code> 类似,如果您想在前台运行,使用:</p>
|
||
|
<pre><code class="lang-bash">kubectl run [-i] [--tty] --attach <name> --image=<image>
|
||
|
</code></pre>
|
||
|
<p>与 <code>docker run ...</code> 不同的是,如果指定了 <code>--attach</code> ,我们将连接到 <code>stdin</code>,<code>stdout</code> 和 <code>stderr</code>,而不能控制具体连接到哪个输出流(<code>docker -a ...</code>)。</p>
|
||
|
<p>因为我们使用 Deployment 启动了容器,如果您终止了连接到的进程(例如 <code>ctrl-c</code>),容器将会重启,这跟 <code>docker run -it</code>不同。 如果想销毁该 Deployment(和它的 pod),您需要运行 <code>kubeclt delete deployment <name></code>。</p>

<p>现在是时候提一下 pod 和容器之间的细微差别了;默认情况下如果 pod 中的进程退出 pod 也不会终止,相反它将会重启该进程。这类似于 docker run 时的 <code>--restart=always</code> 选项, 这是主要差别。在 docker 中,进程的每个调用的输出都是被连接起来的,但是对于 kubernetes,每个调用都是分开的。要查看以前在 kubernetes 中执行的输出,请执行以下操作:</p>
