You can secure your CI/CD pipeline using multiple security measures, also known as a layered defense. These measures should include restricting access to the code repository, encrypting data, and monitoring activity. Software developed using the CI/CD model typically presents no surprises once the code is committed to a live environment. CI/CD is a way of developing software that allows you to release updates at any time—instead of releasing a major version every six months—while being able to respond to changes in requirements quickly. Fewer tools and toolchains mean less time spent on maintenance and more time spent actually producing high-quality software applications. Tracking them is very important because not only can error rates indicate quality problems, but also ongoing performance and uptime related issues.
These teams prefer the continuous delivery paradigm in which humans review a validated build before it is released. Your CI/CD pipeline should deploy your code to a testing or staging environment to run further tests, just as with continuous delivery. However, you must automate all your tests, and deployment to production should be triggered automatically once the tests are complete. Continuous deployment requires rigorous test automation that is kept up-to-date with each code change since there is no final manual QA stage, and a failed test is the only thing standing in the way of pushing your code to prod. Continuous testing is the automated process of providing feedback throughout the software development life cycle (SDLC).
Run Your Fastest Tests Early
Essentially, branches that are not being tracked by your CI/CD system contain untested code that should be regarded as a liability to your project’s success and momentum. Minimizing branching to encourage early integration of different developers’ code helps leverage the strengths of the system, and prevents developers from negating the advantages it provides. The required isolation and security strategies will depend heavily on your network topology, infrastructure, and your management and development requirements.
The test stage is where the application is subjected to comprehensive automated testing to ensure it meets all functional and non-functional requirements. It’s in this phase that the quality of the build is thoroughly vetted before it reaches end-users. This early detection and correction of issues embody the principle of ‘fail fast,’ which saves time and resources in the software development lifecycle. In this next section, you will add custom rules that ensure your automated tests pass before you can merge pull requests.
Small Mid-Sized Businesses
During the build phase, engineers share the code they’ve developed via a repository to build a runnable iteration of the product. Generally speaking, you’d use Docker to deploy cloud-native software, and this stage of the pipeline builds the necessary Docker containers. If an app doesn’t pass this stage, you should address it immediately because it suggests something is fundamentally wrong with the configuration.

Click the Add Rule button, and follow the steps below to add some best practice protection rules to your repo. The process described above only works if your SCM and CI/CD platform can communicate. When using Git for SCM and GitHub Actions for CI/CD, bidirectional communication comes built-in. However, with other SCMs and CI/CD platforms, you will need to perform additional steps to integrate the two systems. Most systems support webhooks, and some CI/CD platforms can poll your SCM to find out if you have opened any new pull requests. A compelling alternative to this bloat-by-testing is using container programs such as Docker instead.
How can I implement CI/CD in my organization?
By automating the process, the objective is to minimize human error and maintain a consistent process for how software is released. Tools that are included in the pipeline could include compiling code, unit tests, code analysis, security, and binaries creation. For containerized environments, this pipeline would also include packaging the code into a container image to be deployed across a hybrid cloud. Your source code management system plays a critical role in continuous integration by triggering the entire CI/CD pipeline. It is a gatekeeper with the power to block code commits to the mainline branch and deployments to production. It was once commonplace to wait and integrate a large number of code changes all at once when ready to cut a release for production.
Continuous integration automates the process of building, packaging and testing code whenever a team member executes version control changes. This makes it easier for teams to commit code changes more frequently, resulting in improved collaboration and app quality. A continuous integration monitoring CI/CD pipeline is a collection of tools used by developers, test engineers and IT operations staff throughout the continuous software development, delivery and deployment lifecycle. Popular CI/CD tools include CloudBees, Jenkins, Azure DevOps, Bamboo and Team City.
Who should do continuous delivery and when?
It addresses the problem of overloading operations teams with manual processes that slow down app delivery. It builds on the benefits of continuous delivery by automating the next stage in the pipeline. Continuous testing is a software testing practice where tests are continuously run in order to identify bugs as soon as they are introduced into the codebase. In a CI/CD pipeline, continuous testing is typically performed automatically, with each code change triggering a series of tests to ensure that the application is still working as expected. This can help to identify problems early in the development process and prevent them from becoming more difficult and costly to fix later on.
These compress operating systems into barebones packages, therefore also making them highly transportable between teams not physically co-located. Using this kind of technology can make it much more effective to quickly spin up new testing environments as the pipeline requires it. If hurdles stand between the code developers and putting out the production environment, team members may inevitably be tempted to seek out the path of least resistance. CI/CD calls for a radically different approach and this needs to be communicated to all team members. Because the testing phase is automated, it encourages developers to work as quickly as possible on what they do best – development. DevOps is a software development methodology that aims to bridge the traditional divide between development (dev) and IT operations (ops) sides of the development process.
How do you implement a CI/CD pipeline?
CI/CD is a philosophy and set of practices often augmented by robust tooling that emphasize automated testing at each stage of the software pipeline. By incorporating these ideas into your practice, you can reduce the time required to integrate changes for a release and thoroughly test each change before moving it into production. Pre-production deployment is typically the endpoint for continuous delivery pipelines. Once the build is completely validated and stakeholders have confidence in the build’s stability and integrity, it can be deployed to an actual production environment.
The goal is to make the abstract tangible and the technical relatable, all while building a compelling business case for CI/CD. For that reason, adding static analysis to every pipeline is practical, efficient, and helps to ensure that there is no need to trade feedback times for quality and security. CI/CD pipelines are software engineering approaches that are a part of the larger software delivery pipeline.
How DevOps and GitLab CI/CD enhance a frontend workflow
A major function of CI/CD pipelines is to be able to catch bugs or vulnerabilities before they are deployed into production infrastructure. Using CI/CD rules, security and quality assurance teams can dynamically run additional checks based on specific triggers. For example, malware scans can be added when unapproved file extensions are detected, or more advanced performance tests are automatically added when substantial changes are made to the codebase.
