There are many DevOps tools available in the market such as GitLab that help developers optimize their software development and workflow as well. I am using gitlab’s pipeline for CI and CD to build images for my projects. A linting error could mean there What is GitLab Pipelines are problems with the code quality. Something as simple as a typo can bring a pipeline process to a halt, so a lint error can be a call to action to review code changes. One of the jobs is failing, but build passes because the job is allowed to fail.
Let’s see how runners and executors collaborate with Gitlab, looking atGitLab runner execution flow. I recommend using thedocker executor for beginners, which guarantees a new environment for each pipeline run. Decision upon executor may be done when registering your runner in GitLab. But, instead of using shared runners, you can useyour own runners installed on your machine. It is a better solution due to performance and security reasons. In 2015 Kamil Trzciński created his own runner written in Go as a side task, which is great for multi-tasking and parallelization.
Branch, Merge Request, Result, and Train Pipelines
Keep reading to discover the answers and find out more about the benefits of CI/CD pipelines for engineers and enterprises. If you understand the basic concepts of GitLab pipelines, feel free to clonethis repository and run some experiments on your new CI/CD project. You can run some jobs only on a specific branch; you can open merge requests and run jobs after merging.
There’s a free analytics tool, which can help speed up deployment by allowing you to avoid bottlenecks. Try GitLab for freewith access to all features for 30 days.

Multi-project pipeline graphs help you visualize the entire pipeline, including all cross-project inter-dependencies.
Directed Acyclic Graph Pipelines
Ephemeral builds are reproducible meaning they’re going to not be impacted because the server went down. The code in your most recent commit could be vulnerable, or a dependency could be at risk, either of which would trigger a failed security test and thus a failed pipeline. To help avoid failed security tests here are 5 actions a developer should take based on the latest OWASP report on security vulnerabilities.
With the help of GitLab, users can reduce the product lifecycles and increase productivity. In this article, you will explore how you can use Scheduled Pipelines to run CI/CD pipelines at uniform intervals. Multi-project pipelines are standalone pipelines because they are normal pipelines, but just happen to be triggered by an another project’s pipeline.
Benefits of GitLab Scheduled Pipelines
Pipelines can be manually executed, with predefined or manually-specified variables. Starting in GitLab 14.2, you can change the pipeline column to display the pipeline ID or the pipeline IID. Join our teal organization and work on challenging projects. When an executor is done, it uploads job output and job status to GitLab.
Each step in a workflow operates in its own container and pod. This allows pipelines to take advantage of the distributed architecture of Kubernetes to easily scale both on the number of running workflows and within each workflow itself. At the end of the pipeline creation wizard, Codefresh commits the configuration to git and allows its built-in Argo CD instance to deploy them to Kubernetes. If a pipeline fails frequently, look for common patterns in failed jobs, such as randomly failing unit tests, insufficient test coverage, and failed tests that slow down feedback. Merged results pipeline—runs on a result of merging changes to the source branch with the target branch. For instance, your project could have a separate tool or website.
What is a CI/CD Pipeline? How does it Work in GitLab?
In this example, the Wiki page of the project is used to create a simple table in markdown that will show all projects in a group. If you have a private project, you can use a personal access token or a private access token. And if you want to access numerous projects, you can use the personal access token. If any of the jobs in a stage fail, the next stage is not executed, and the pipeline terminates early. If all jobs in a stage are successful, the pipeline advances to the next stage.
Changes are validated by an automated build, with unit and integration tests ensuring any changes made haven’t broken the application. If testing uncovers a conflict between new and existing code, CI makes fixing bugs faster and more frequent. This pipeline architecture is commonly used for mono-repos. Merged results pipelinesare merge request pipelines that act as though the changes from the source branch have already been merged into the target branch. The main difference is that Gitlab pipelines allow collaboration and provide a clean environment for each build because docker images may be used.
GitLab Pipeline
Keep in mind that there’s no manual barrier in place before production, so watertight test automation is essential. Automated pipelines can help prevent errors that result from manual processes, allow for rapid product iterations, and provide consistent feedback during the development process. Each step of a CI/CD pipeline is a subset of tasks grouped into pipeline stages, which we discuss in detail further down in this article. It means that cache is shared between pipelines, but artifacts don’t.
- Upstream pipelines take precedence over downstream ones.
- Create a project and set it as private or public in GitLab.
- These keywords are ways to store dependencies and job output, even when using ephemeral runners for each job.
- As a default, you may want to use shared runners provided by GitLab.
- You should surely adjust the job rules according to your needs.
Deployment pipelines can be automated where once the code gets into staging we can push it into production based on our requirements and timelines. The code is taken from the development environment as it is placed by the CI pipeline already. Continuous integration pipeline involves building something from the scratch and testing the same in a development environment. It might occur to the developers to add something after building the application and pushing it into production.

It will also provide information on how to trigger a pipeline status report using the GitLab Pipeline API. You can view things like the number of currently-running jobs and how much CPU your runners are using. You can configurethe runner by editing the config.toml file. This is a file that is installed during the runner installation process.
