font-family: -apple-system, BlinkMacSystemFont, " helvetica="" pingfang="" microsoft="" source="" han="" sans="" noto="" cjk="" wenquanyi="" micro="" font-size:="" white-space:="" background-color:=""/>使用 Docker，开发人员可以通过编写 Dockerfile 来创建容器化应用程序，这本质上是构建容器映像的秘诀。然后，Docker 提供了一组工具来构建和管理这些容器映像，使开发人员能够更轻松地以一致且可重复的方式打包和部署应用程序。<br style="color: rgb(25, 27, 31); font-family: -apple-system, BlinkMacSystemFont, " helvetica="" pingfang="" microsoft="" source="" han="" sans="" noto="" cjk="" wenquanyi="" micro="" font-size:="" white-space:="" background-color:=""/>这些容器映像可以在任何支持容器的平台上运行，例如 Kubernetes、Docker Swarm、Mesos 或 HashiCorp Nomad。Docker的平台使开发人员可以更轻松地创建和管理这些容器镜像，从而简化了跨不同环境构建和部署应用程序的过程。</p><p class="maodian"></p><h3>Kubernetes（K8s） 全面介绍</h3><p>Kubernetes，也称为 K8s，是一个著名的开源平台，旨在跨网络资源集群编排容器运行时系统。它可以独立运行，也可以与其他容器化工具（例如 Docker）结合使用。</p><p>Kubernetes 提供了一种实用的解决方案，用于在一台机器上管理一组容器，以减少网络开销并优化资源利用率。例如，一个容器集可以由应用服务器、Redis 缓存和 SQL 数据库组成。相比之下，Docker 容器被设计为每个容器运行一个进程。</p><p>随着容器的激增，组织最终可能会拥有数百甚至数千个容器，这使得运营团队必须自动化容器部署、网络、可扩展性和可用性。这导致了容器编排市场的出现。</p><p>开发人员选择 Kubernetes 是因为它具有广泛的功能、庞大且不断增长的开源支持工具生态系统，以及它支持各种云服务提供商和工作的能力。所有主要公共云提供商，包括 Amazon Web Services (AWS)、Google Cloud、IBM Cloud 和 Microsoft Azure，都提供完全托管的 Kubernetes 服务，这凸显了其在全行业的受欢迎程度。</p><h3 style="margin-top: 1.4em;
