Continuous Integration DevOps

SIGNS YOU’RE MASTERING CONTINUOUS INTEGRATION

Most organisations believe that they do continuous integration (CI), but the question of whether they adhere to key CI practices, such as running tests to validate each version, many are not.

Continuous delivery (CD), the basis of DevOps, is based on continuous integration practices. Therefore, you must correctly implement CI to be able to really achieve success with CDs and DevOps. In other words, you have to crawl before you go.

Steps to master continuous integration to achieve business goals, here are seven practices that organizations must do to master CI:

•   Build as often as possible – Teams building CI building many times a day, preferably running compilation based on a change on request to pull, merge or commit. Building according to the approval allows you to detect errors immediately after they are introduced and it is easier to repair them.

•   Commit or merge to mainline often – CI executing teams probably perform / connect to the main or main bus with each change or at least once a day. For example, if you maintain long-running feature branches, you often do not get the benefit of validating integrated changes. If you are creating a branch for a long time, after integrating it, the integration has been delayed and you may have to deal with conflicts or errors to be fixed.

•   Build fast – Take the time to optimise build time and validate. This may require decomposing the CI build process to adapt to components or assemblies, and then verifying the entire integrated application as a separate step throughout the programming process.

•   Check the correctness of the compilation – CI includes validation of changes and resulting changes. This type of testing should be part of the entire compilation process. If your only validation is based solely on confirming the compilation of software and links, you are not really practicing CI. Most CI training teams include code scans and unit tests in the CI build.

•   Confirm in a production-like environment – Professional and Trained CI developers ensure consistency between programming, test and pre-production environments. The most mature use virtual machines or containers, virtualization services and other techniques to ensure that they perform validation in a production environment and reduce the risk of errors being detected in the pre-production or production phase, also after the changes.

•   Repair broken builds immediately – As mentioned above, it is very important that teams quickly find and fix problems so that they do not move down. If spoiled compilations are ignored, the problem will be harder to find and fix, but the culture it encourages is worse. CI is based on a quality approach. If the compilation fails, “stop the line” and repair the compilation. In the long run everyone will be better for him.

•   Do not forget about culture – If an organisation can look at these seven characters and say it does all these things, it really does CI. It may seem simple, but when these rules are combined, the result is extraordinary.

Conclusion –

Continuous integration is one of the fundamental elements of the true DevOps transformation, which – as you know – is a priority for many companies today. The correct performance of this task is necessary to keep up with modern business needs.
