Continuous integration, continuous delivery, and continuous deployment (CI/CD) have existed in the developer community for decades. Some organizations have involved their operations counterparts, but many haven’t. For most organizations, it’s imperative for their operations teams to become just as familiar with CI/CD tools and practices.
Continuous integration, continuous delivery, and continuous deployment (CI/CD) are terms that have existed in the developer community for decades. Some organizations have involved their operations counterparts, but many haven’t. For most organizations, it’s imperative for their operations teams to become just as familiar with CI/CD tools and practices.
Continuous Integration is a coding practice that essentially enables the development team to make and implement small changes in the code and version control methods quite frequently.
CI allows developers to continuously update changes to a single repository, from where automated builds and tests are made.
Usually, traditional system admins roles do not involve developing continuous integration pipelines, but if you are looking to dive into DevOps, getting hands-on experience with continuous integration tools is a must. Because most modern applications require developing code in different platforms and tools, the team needs a mechanism to integrate and validate its changes. The technical goal of CI is to establish a consistent and automated way to build, package, and test applications. With consistency in the integration process in place, teams are more likely to commit code changes more frequently, which leads to better collaboration and software quality.
As you learn more about these tools and start bringing these practices into your company or your operations division, you'll quickly understand the need and importance of CI tools. You will increase your own productivity as well as that of others. With the growing number of available CI / CD tools on the market, teams may find it difficult to make decisions to select the right tools. Let's get into the tools a bit more. We'll briefly cover some highly-rated tools and share links to more information.
Jenkins is an automation tool written in Java with built-in plugins for continuous integration tasks. It is used to continuously build and test projects making it easier to integrate the changing codes to it.
Jenkins allows for faster delivery of software by working with a large number of deployment and testing technologies. It also accelerates the development phase via the automation of tasks. It is primarily a server-based app and requires a web server like Tomcat.
It allows a lot of flexibility and additional plugins that provide extra features, quite often not possible to find elsewhere unless you want to spend time on providing that by yourself. One of key features is pipelines that allow you to easily chain different jobs even across different repositories/projects.
CircleCI is a strong SaaS-based CI product that enables testing in the cloud. The YAML-based configuration system allows individual developers to test CI/CD changes and push changes effectively and quickly. The variety of different platforms that are supported allows multiple people to centralize on a single solution to avoid spread to other products. CircleCI is the worlds largest shared continuous integration and continuous delivery (CI/CD) platform, and the central hub where code moves from idea to delivery. As one of the most-used DevOps tools that processes more than 1 million builds a day, CircleCI has unique access to data on how engineering teams work, and how their code runs. Companies like Spotify, Coinbase, Stitch Fix, and BuzzFeed use us to improve engineering team productivity, release better products, and get to market faster.
Automated builds! This is really why you get CircleCI, to automate the build process. This makes building your application far more reliable and repeatable. It can also run tests and verify your application is working as expected.
Straightforward CI tooling. No need to spin up a CI server like Jenkins/ TeamCity to get things moving.
Bamboo provides the facility of automatic build generation. Using Bamboo a lot of time and manual efforts can be saved. Bamboo is very easy to use and has a simple user interface. Bamboo provides the facility of continuous integration and continuous deployment. So whenever any change is there in the bitbucket it automatically gets integrated with the previous code and generates the build. Bamboo provides the feature of running the automation test case on the build which saves a lot of time. Bamboo provides various options for configuration management. One can easily configure multiple branches, write a script, and can execute it. Bamboo provides various agents for building the build. Bamboo support community is always ready to help.
TeamCity is the go-to tool for getting the Builds and Deployments packages for a variety of platforms like .NET, Java and JS, etc. It unifies the build and deployments needs of all the diverse projects to a single platform and solves the build and release issues previously we faced and reduces the time to go to Prod. TeamCity will make sure your software gets built, tested, and deployed, and you get notified about that appropriately, in any way you choose. It’s a continuous integration and deployment server from JetBrains which takes moments to set up, shows your build results on-the-fly, and works out of the box. And best of all – it’s free by default.
Once set up and configured, it's incredibly easy to test and release a piece of code, and diagnose problems across multiple teams using the online platform. Highly customizable, such as which outputs to test, what to save, and on which machines the tests should be run. Non-regression tests can also be run locally when developing them, to ensure they meet your requirements for robustness, before executing them remotely.
Gitlab is well suited for any project that requires revision tracking along with collaboration with other contributors. It supports the standard features of Git and adds its own recipe to the features that other Git SaaS providers offer as well. This includes issue tracking, pull request management, and recent artifact and package management. Gitlab has also been a leader in bringing CI to the repo ahead of its competitors. Of course, not all of these features need to be used. If all a dev needs are to track code, Gitlab can handle that just as well as any other cloud or self-hosted repo.
Travis works great for CI/CD pipelines. It's easy to configure and has great integrations with tools you are probably already using like Github. It's also compatible with many popular languages. It automates the build process and handles test cases. You can run test cases on mac and Linux both at the same time. Configuring Travis is easy using a lightweight YAML file. We don't need to set up our own server to run it. It also provides free support for public repositories. Ready and easy to use, you don’t need any extra configuration like other CI toolss like Jenkins. simply integrate GitHub or version control system, whenever you push the code it's tested and integrated. Multiple jobs allow you to run and test simultaneously on different environments and OS. Free for your public projects, you don’t have to pay for your test and open source projects. You don’t have to maintain hosting server, Travis CI handle, and maintain updates and hosting server. Plugin and integration with third-party tools are available but it's limited.
The best thing about Buddy is its intuitive UI where you can set up deployment pipelines easily. The UI really helps when we want to introduce CI/CD culture to the whole engineering team since they can try to set up themselves using a few button clicks, rather than learning about some YAML configuration (it's still available for some advanced users though).
It also has a plethora of built-in actions that connect with so many services that cover almost all of our use cases. Even if when we can't find what we need, its integration with Docker Hub is really helpful so we can set up our own custom Docker image.
Buddy's GUI is really awesome and to create pipeline's using Buddy is really really simple. For a beginner who doesn't understand CICD much, start using Buddy and you will get to know everything related to CICD in a day. Buddy is also constantly improving and new features every day.
