   <p style="text-align: center;"><img alt="" src="https://simg.open-open.com/show/42d9d04e7ae043e37eaf993e9d8519d2.png" /></p>    <p>Kubernetes是Google开源的容器集群管理系统，其提供应用部署、维护、 扩展机制等功能。利用Kubernetes能方便地管理跨机器运行容器化的应用。</p>    <p>如果你曾经用过<a href="http://www.open-open.com/lib/view/open1463535082208.html">Docker</a>容器技术部署容器，那么可以将Docker看成Kubernetes内部使用的低级别组件。Kubernetes不仅仅支持Docker，还支持Rocket，这是另一种容器技术。</p>    <p>使用Kubernetes可以：</p>    <ul>     <li>自动化容器的部署和复制</li>     <li>随时扩展或收缩容器规模</li>     <li>将容器组织成组，并且提供容器间的负载均衡</li>     <li>很容易地升级应用程序容器的新版本</li>     <li>提供容器弹性，如果容器失效就替换它，等等...</li>    </ul>    <h2>更新日志</h2>    <p>Moved init-container feature from alpha to beta. (<a href="/misc/goto?guid=4958993387288725841">#31026</a>, <a href="/misc/goto?guid=4958992687856091459">@erictune</a>)</p>    <ul>     <li>Security Action Required:</li>     <li>This only applies to you if you use the PodSecurityPolicy feature. You are using that feature if <code>kubectl get podsecuritypolicy</code> returns one or more objects. If it returns an error, you are not using it.</li>     <li>If there are any pods with the key <code>pods.beta.kubernetes.io/init-containers</code>, then that pod may not have been filtered by the PodSecurityPolicy. You should find such pods and either delete them or audit them to ensure they do not use features that you intend to be blocked by PodSecurityPolicy.</li>     <li>Explanation of Feature</li>     <li>In 1.3, an init container is specified with this annotation key</li>     <li>on the pod or pod template: <code>pods.alpha.kubernetes.io/init-containers</code>.</li>     <li>In 1.4, either that key or this key: <code>pods.beta.kubernetes.io/init-containers</code>,</li>     <li>can be used.</li>     <li>When you GET an object, you will see both annotation keys with the same values.</li>     <li>You can safely roll back from 1.4 to 1.3, and things with init-containers</li>     <li>will still work (pods, deployments, etc).</li>     <li>If you are running 1.3, only use the alpha annotation, or it may be lost when</li>     <li>rolling forward.</li>     <li>The status has moved from annotation key</li>     <li>更多日志见：<a href="/misc/goto?guid=4958993387404916336">CHANGELOG</a></li>    </ul>    <h2>下载</h2>    <ul>     <li><a href="/misc/goto?guid=4958993387500061388" rel="nofollow"><strong>kubernetes.tar.gz</strong></a></li>     <li><a href="/misc/goto?guid=4958993387588044279" rel="nofollow"><strong>Source code</strong> (zip)</a></li>     <li><a href="/misc/goto?guid=4958993387672190263" rel="nofollow"><strong>Source code</strong> (tar.gz)</a></li>    </ul>    <p>本站原创，转载时保留以下信息：<br /> 本文转自：深度开源（open-open.com）<br /> 原文地址：<a href="http://www.open-open.com/news/view/35c28224">http://www.open-open.com/news/view/35c28224</a></p>    <p> </p>
