DevOps best practices and cases

How unload your DevOps team using templates?

   Templates are a set of practices and ready-to-use tools. It can be used to speed up deployment and creation of infrastructure. Developers can use them to define reusable content, parameters, and tools. DevOps specialists have created this ready-to-use code to make recurring manual operations faster. By creating them developers have to manually create a code, which contains appropriate parameters or configurations. The template requires appropriate syntax and structure, this pieces of code has to be checked to work well. When the developer needs some complex configuration, it will use several simple templates. Also, it can define a path that files will follow or contains a file, which will be inserted into an app. Although templates can make the work of DevOps specialists simpler, there is no need in spending time, creating a lot of complex piece of code. There is no point in making something that is rarely used. So, templates are a commonly used configuration, practices, tools that a developer can use to speed up deployment processes.


Templates in infrastructure creation

   Templates are widely used to create an infrastructure. One template can include whole components and resources that are needed for working infrastructure. Once it is deployed, all these resources create and can be managed. For example, templates are used in Terraform and CloudFormation. These utilities can be used for managing and utilizing resources with an infrastructure-as-a-code approach. Terraform and Cloud Formation allows using configuration files to set up the infrastructure. This feature makes it possible to create a reusable code that can be considered as a template. Reusable code can be implemented in simple blocks and can be inserted inside a configuration file. This file will be uploaded to the system and creates the infrastructure.

Pipeline templates

Another usage of templates is in pipelines. It is possible to state that pipelines are a set of templates that are used to deploy applications inside the infrastructure. In this case, templates are also configuration files and they execute a particular function inside the pipeline. It is better to start making templates when you have more than one working pipeline. It would be easier to find common treats such as build and deploy or to perform some common tests. Jenkinsfiles, Azure Pipelines, GitHub Actions, GitLab CI/CD use configuration files as templates for configuration.

Security templates

   Templates are often used in security. They can make an easier installation of security policies and can increase the hardening of infrastructure. DevOps during his daily workflow from time to time face a security issue, which requires a configuration of new security policies. DevSecOps, who works with the security sphere, often faces the issues of making some tests or managing policies. Templates can make these procedures faster and more effective. As a result, with working templates, it would be much easier to manage security issues, because the specialist can quickly create the basic parameters and then manually modify it according to the task. 

   To conclude, a template is a ready-to-use piece of code that can make an action, they are important in the job of the DevOps. It is used to make commonly used actions easier. Templates make it possible to foster the processes of installing the infrastructure, managing security, or configure CI/CD pipelines. The use of templates is commonly used practice among DevOps specialists. In the majority of cases, this practice helps to improve the performance of the team as well as achieve more complete tasks per unit of time.
