How and Why You Need to Use Dockers In CI & CD

CI and CD are two of the most important aspects of a successful software development process. CI is short for continuous integration, which means that developers merge their code with the main branch all the time. This makes sure that any problems will be fixed quickly. CD stands for continuous deployment, which means that once a developer finishes working on a feature, it goes live immediately instead of being stored in development until later. We’ll discuss how 

Docker can help you achieve ci cd docker more effectively in this blog post.

What is Docker?

Docker is a tool for building, shipping and running distributed applications. It has been developed by the company Docker Inc., which was acquired in 2016 by Microsoft Corp. No matter if you are a developer or sysadmin – it’s easy to get started with Docker because everything comes in containers that can be easily downloaded from repositories such as Docker Hub.

What do we mean when we say “containers”?

Containers isolate processes on servers while sharing an OS kernel. They help developers avoid dependency issues between different services that run concurrently on one server but still provide much more isolation compared to virtual machines (VMs). This brings us closer to container orchestration, where multiple docker containers work together side-by- within software stacks, making them easier to manage and scale.

What can you do with Docker?

Building

With Docker, it’s easy to build development environments that are the same as production ones. This means that developers will be able to work on their projects without worrying about the differences in dependencies between different operating systems. It also helps them avoid problems caused by missing libraries or other packages while developing locally.

Shipping

You already know what continuous integration is, right? Where many small changes made by developers all over the world get merged into one big branch every day so there won’t be any conflicts later when new features are added on top of each other (branch merging The problem was always how to merge the changes back into the “master” branch) Docker solved this problem by introducing the concept of images and containers. Now, when a developer commits a change to his local repository, a new image is created which contains all the dependencies needed to run that particular application. This image can then be pushed to a registry such as Docker Hub, where it can be accessed by anyone who needs it.

Running

Dockers make it possible to create clusters of machines that easily run Docker containers. You can either use your own physical or virtual machines or use services like AWS EC.

How does Docker help with CI/CD?

To merge their code with the main branch quickly and without conflicts, they need to work in an environment similar to production. This includes all of the dependencies, system libraries and even OS kernel patches if needed. Of course, this can be done using VMs with pre-installed operating systems, but it’s much easier to just use docker containers or docker alternatives which already contain most of these things anyway.

Conclusion

The new generation of applications has the potential to change the way we do business, but it needs a few more pieces to make that happen. One of those is Docker’s container technology which makes CI & CD easier than ever before. We can help you get your team on top of this game-changing technology with tailored training and consulting for each step in its adoption process.
