This article mainly introduces "what is the process of turning to CI/CD in docker". In daily operation, I believe that many people have doubts about the process of turning to CI/CD in docker. The editor consulted all kinds of materials and sorted out simple and easy-to-use methods of operation. I hope it will be helpful to answer the doubt of "what is the process of turning to CI/CD in docker?" Next, please follow the editor to study!

What is continuous integration (CI)?

So what on earth is continuous integration (CI)? It is the process by which software engineers frequently pass copies of the updated code to a shared location every day. All development work is integrated at scheduled times or events, and then automated testing and build work. Through CI, errors in the development process can be found in time, which not only accelerates the whole development cycle, but also makes software engineers more efficient.

What are the benefits of continuous integration?

We cannot underestimate the benefits of CI. Because everyone on the team works on the same product in real time, you can expect faster speed, better stability, and greater reliability when using CI in the software development process. And early in the development process, developers can identify and resolve any coding problems so that they can be corrected before they become major downstream problems. This reduces the cost of long-term development (and business) caused by the error code.

Continuous integration also has a big impact on the time spent on QA testing. With CI, developers constantly review and edit previous code and are able to detect a number of minor errors that are usually found later in QA. This allows testers not only to focus on code and more pressing issues, but also to test more scenarios at the same time.

For development teams, another benefit of using CI is that you can improve your coding capabilities. Because of the natural flexibility of continuous development, this allows developers to make changes to the code quickly and easily without the risk of running regression.

What is continuous delivery (CD)?

Continuous delivery (CD) is the second challenge in creating high-quality applications. CD is a software development discipline that uses technologies and tools to quickly deliver code in the production phase. Because most of the delivery cycles are automated, these deliveries can be completed quickly.

What are the benefits of continuous delivery?

The main benefit of implementing continuous delivery is the ability to accelerate time-to-market for applications. Companies that use CD can greatly increase the frequency of their applications. Before using CD, applications are usually released once a few months. Now, however, with CD, you can release apps once a week, or even multiple times a day. In a highly competitive industry, the increase in speed will give you a major advantage.

Continuous software releases also allow the development team to fine-tune the application based on user feedback. This user feedback provides developers with the insight they need, and it gives priority to the functional requests that users actually need. Just as important, it allows developers to prioritize application functions that users don't actually use.

Another benefit of CD is that it ensures that the risk of each distribution is low. When released using the CD approach, the development team is also more confident because everything has been tested many times throughout the development lifecycle.

Any company that does not consider turning to CI / CD may be left behind by competitors who use the CI / CD approach. So, how do you turn to CI / CD? When you are ready to move to continuous integration / continuous delivery (CI / CD), there are many processes to consider and decide. The following will take you through these main processes.

Shift to critical process 1, branching, and merging of CI/CD

One of the main processes you need to organize and consider is your branching and merging. A branch is where a developer can work in parallel parts of the code-- from a central code base. The advantage of branching is that it allows you to work on different aspects of software construction at the same time without breaking the central code base. Obviously, merging means merging branches into the core code base.

Through various version control systems, many developers are already familiar with branching and merging. However, depending on the specific requirements of your build, there are many different strategies for the content you branch. Some developers will release branches through maintenance, functionality, or teams.

You may be crazy about a strategy, but there are no "absolutely right" branching and merge strategies, only "right for your build" approaches and strategies. This requires reviewing your current branching and merging strategy and deciding what needs to be changed based on your goals and circumstances.

2. Build automation

Build automation means that you can compile software builds automatically. The core of the continuous integration server is to build the automation server, whose job is to compile and link the source code on the basis of trigger or timing. The continuous integration server you choose will be the backbone of your CI/CD environment.

When looking at the build automation process, it is helpful to understand the capabilities of the various options available on the market. Jenkins, an open source company, now dominates CI/CD deployment, which is usually a good start. Or at least use it as a benchmark when comparing other solutions. As an open source code system, you may still need to build some utilities to make build automation fully suited to your situation.

3. Test automation

Test automation is critical to whether CI/CD can work as expected. Without automated testing, CI/CD will soon fail to achieve its goal of rapid delivery. Our overall advice is to be as automated as possible. This means that you need to check the various tests you need to perform and decide which tests can be safely automated in your environment.

Establishing a test automation environment may require new skills. However, this is a strategic requirement that will increase delivery speed and reduce errors. At a minimum, you should automate code review, unit testing, integration testing, and system testing.

4. Deployment automation

There is still some confusion about the difference between continuous delivery and continuous deployment. In short, continuous delivery means continuous release-ready code, while continuous deployment means continuous deployment of the software to users.

No matter what "CD" you are watching, it seems like a giant leap for those who are not used to it. To give your organization the confidence to deploy software to end users, you need a rigorous test automation infrastructure.

Our recommendation is that it is best to enter the process definition to achieve the overall goal of zero-touch continuous deployment. Although leading continuous integration systems usually consider their own continuous delivery systems, you can go further than off-the-shelf parameters. True agility requires building an infrastructure and writing code to attract users.

Choose open source and complete CI/CD tools

It is not easy to realize CI/CD, the construction of pipeline is complicated, smooth upgrade is difficult to guarantee, and service downtime is hard to avoid. Choosing a complete CI/CD tool will greatly help CI/CD to land in the enterprise and eventually improve the efficiency of production, operation and maintenance. Rancher Labs's newly released CI/CD tool, Rancher Pipeline, has a minimalist operating experience, powerful functional integration, and is completely open source.

Simultaneous support for multi-source management: pulling, using, and managing code hosted on GitHub and GitLab simultaneously in a single environment

One-click deployment, fully visual pipeline configuration, drag-and-drop pipeline building

Staged and stepped pipeline, freely extensible step system

Flexible process control: different code branches can automatically match different CI processes, thus supporting more complex process control

Support for multiple triggers: trigger of scheduled tasks, webhook trigger from GitHub / GitLab, manual trigger, and support for more triggers through customized development

Well-integrated approval system: the examination and approval system has been integrated with the Rancher user management system, and users can insert breakpoints at any stage and approve at any stage freely.

Flexible pipeline start and stop mechanism: if any link goes wrong, the whole progress can be stopped immediately, and the problem can be rerun after the problem is solved.

At this point, the study on "what is the process of turning to CI/CD in docker" is over. I hope to be able to solve your doubts.
