 虽然持续集成、持续交付和持续部署（CI/CD）在开发者社区里已经存在很多年，一些机构在运维部门也有实施，但大多数公司并没有做这样的尝试。对于很多机构来说，让运维团队能够像他们的开发同行一样熟练操作 CI/CD 工具，已经变得十分必要了。
 
 CI/CD practices can equally apply to infrastructure and third-party applications and internally developed applications. Also, there are many different tools but all use similar models. And possibly most importantly, leading your company into this new practice will put you in a strong position within your company, and you'll be a beacon for others to follow.

 Some organizations have been using CI/CD practices on infrastructure, with tools like [Ansible][1], [Chef][2], or [Puppet][3], for several years. Other tools, like [Test Kitchen][4], allow tests to be performed on infrastructure that will eventually host applications. In fact, those tests can even deploy the application into a production-like environment and execute application-level tests with production loads in more advanced configurations. However, just getting to the point of being able to test the infrastructure individually is a huge feat. Terraform can also use Test Kitchen for even more [ephemeral][5] and [idempotent][6] infrastructure configurations than some of the original configuration-management tools. Add in Linux containers and Kubernetes, and you can now test full infrastructure and application deployments with prod-like specs and resources that come and go in hours rather than months or years. Everything is wiped out before being deployed and tested again.

+一些机构在自己的基础设施上已有多年的 CI/CD 实践经验，常用的工具包括 [Ansible][1]、[Chef][2] 或者 [Puppet][3]。另一些工具，比如 [Test Kitchen][4]，允许在用于生产的基础设施上运行测试。事实上，如果使用更高级的配置方法，甚至可以将应用部署到有真实负载的仿真“生产环境”上，来运行应用级别的测试。然而，单单是能够测试基础设施就是一项了不起的成就了。配置管理工具 Terraform 可以通过 Test Kitchen 来快速创建可复用的基础设施配置，这比它的前辈要强不少。再加上 Linux 容器和 Kubernetes，在几小时内，你就可以创建一套类似于生产环境的配置参数和系统资源，来测试整个基础设施和其上部署的应用，这在以前可能需要花费几个月的时间。而且，删除和再次创建这些测试也非常容易。
 
 However, you can also focus on getting your network configurations or database data definition language (DDL) files into version control and start running small CI/CD pipelines on them. Maybe it just checks syntax or semantics or some best practices. Actually, this is how most development pipelines started. Once you get the scaffolding down, it will be easier to build on. You'll start to find all kinds of use cases for pipelines once you get started.
