What is difference between GitLab CI and Jenkins?

Both tools come with their pros and cons. While Gitlab gets an edge in code collaboration and version control, Jenkins fares well in continuous integration. As such, you cannot rate one tool over the other in the Gitlab vs Jenkins CI/CD battle.

Why CI CD is required?

CI/CD allows organizations to ship software quickly and efficiently. CI/CD facilitates an effective process for getting products to market faster than ever before, continuously delivering code into production, and ensuring an ongoing flow of new features and bug fixes via the most efficient delivery method.

What is an example of CI?

Here is example of CI/CD pipeline: Source Code Control: Host code on GitHub as a private repository. This will help you to integrate your application with major services and software. Continuous integration: Use continuous integration and delivery platform CircleCI and commit every code.

What is gitlab in DevOps?

GitLab is a single application for the entire DevOps lifecycle, meaning we fulfill all the fundamentals for CI/CD in one environment.

Why is CI/CD pipeline important?

CI/CD pipelines can determine what happens when builds pass or fail these tests, meaning that errors are identified much faster. As code goes through each stage of the development process, it is continually validated against many other changes in the repository happening concurrently, which ensures code integrity throughout the pipeline. Together, CI and CD accelerate how quickly your team delivers results for your customers and stakeholders.

What is continuous integration?

Continuous Integration is the practice of integrating code into a shared repository and building/testing each change automatically, as early as possible; usually several times a day.

What is SCM in programming?

Source code management (SCM) that houses all necessary files and scripts to create builds.

What should testing scripts ensure?

Code should be tested in a cloned version of the production environment.

What is Gitlab CI?

Continuous integration and development in Gitlab help in finding the bugs in the codes and correcting it without consuming more time in development. CICD also ensures that the production code has all the code compliance with respect to our app development.

How to Manage Secrets in GitLab CI?

CI requires some secrets where sensitive information is stored to perform and complete the project deployment work. Any information ranging from API tokens, sas keys or database information that can be obtained from the service provider. These secrets are required by the job to complete the deployment and this step cannot be ignored.

Conclusion

Gitlab CI helps in any kind of testing as this helps the developers to make the process faster in the application. We can also link dockers and Kubernetes in the application to manage the process where we can use various repositories stored in the cloud and make the process more efficient and interactive.

What is a ref in GitLab?

The refs refs/heads/<name> and refs/tags/<name> exist in your project repository. GitLab generates the special ref refs/pipelines/<id> during a running pipeline job. This ref can be created even after the associated branch or tag has been deleted. It’s therefore useful in some features such as automatically stopping an environment , and merge trains that might run pipelines after branch deletion.

What is gitlab metadata?

This includes the Git refspecs , which indicate which ref (branch, tag, and so on) and commit (SHA1) are checked out from your project repository.

What is a DAG pipeline?

Directed Acyclic Graph Pipeline (DAG) pipelines are based on relationships between jobs and can run more quickly than basic pipelines.

How to delete a pipeline in CI/CD?

Users with the Owner role in a project can delete a pipeline by clicking on the pipeline in the CI/CD > Pipelines to get to the Pipeline Details page, then using the Delete button.

How many stages are there in a pipeline?

However, there are also times when you can manually interact with a pipeline. A typical pipeline might consist of four stages, executed in the following order: A build stage, with a job called compile . A test stage, with two jobs called test1 and test2 . A staging stage, with a job called deploy-to-stage .

Where is the latest commit in GitLab?

Starting in GitLab 12.3, a link to the latest pipeline for the last commit of a given branch is available at /project/pipelines/ [branch]/latest . Also, /project/pipelines/latest redirects you to the latest pipeline for the last commit on the project’s default branch.

What is pipeline in continuous integration?

Pipelines are the top-level component of continuous integration, delivery, and deployment. Pipelines comprise: Jobs, which define what to do. For example, jobs that compile or test code. Stages, which define when to run the jobs. For example, stages that run tests after stages that compile the code.

How many stages are there in a pipeline?

The full pipeline in the example is composed of three jobs, grouped into two stages, build and test. The pipeline runs every time changes are pushed to any branch in the project.

Does GitLab run pipelines?

You create the strategy for your app and GitLab runs the pipeline according to what you’ve defined. Your pipeline status is also displayed by GitLab:

Where is gitlab-ci.yml?

A file called .gitlab-ci.yml in the root of your repository, which contains the CI/CD configuration.

Can you group CI/CD scripts into stages?

You can group multiple independent jobs into stages that run in a defined order. The CI/CD configuration needs at least one job that is not hidden .

What is gitlab in software?

GitLab is more than just source code management or CI/CD. It is a full software development lifecycle & DevOps tool in a single application.

What is CI/CD pipeline?

A CI/CD pipeline is a seamless way for developers to make changes to code that are then automatically tested and pushed out for delivery and deployment. The goal is to eliminate downtime. Get CI/CD right and you’re well on the road to successful DevOps and dramatically faster code release. In our 2020 Global DevSecOps Survey, nearly 83% of survey takers said they’re getting code out the door more quickly thanks to DevOps.

Why is CI/CD important?

Four benefits of CI/CD. Yes, CI/CD helps speed up delivery of code but it also makes for happier software developers. At a time when there continues to be a worldwide shortage of software developers, it’s critical to retain technical talent. Developer job satisfaction is just one of four key benefits that come from implementing a CI/CD process.

What is auto devops?

Auto DevOps is our solution to this problem. It is a pre-built, fully-featured CI/CD pipeline that automates the entire delivery process. Instead of having to choose between time and flexibility, GitLab offers both. In addition to the Auto DevOps template, GitLab offers several CI templates that can be modified as necessary, or you can override specific settings. Want all the power of Auto DevOps for a custom test job? Just override the script block for the test job and give it a try. Since templates are also modular, teams have the option to pull in only the parts they need.

What is CI/CD pipeline?

A CI/CD pipeline automates steps in the SDLC like builds, tests, and deployments. When a team takes advantage of automated pipelines, they simplify the handoff process and decrease the chance of human error, creating faster iterations and better quality code. Everyone can see where code is in the process and identify problems long before they make it to production.

Why is pipeline important in software development?

The pipeline as code model creates automated processes that help developers build applications better and faster. Having everything documented in a source repository allows for greater visibility and collaboration so that everyone can continually improve processes, which is what DevOps is all about.

What is a job in a runner?

Job: Instructions that a runner has to execute.

Can you see links in gitlab?

In GitLab 9.3 we made it possible to display links for upstream and downstream projects directly on the pipeline graph, so developers can check the overall status of the entire chain in a single view. Pipelines continue to evolve, and in our CI/CD product vision we’re looking into making pipelines even more cohesive by implementing Multiple Pipelines in a single .gitlab-ci.yml in the future.

What version of GitLab supports project, group, and instance variables?

Support for project, group, and instance variables added in GitLab 14.2.

What is CI commit_ref_name?

When used in include, the CI_COMMIT_REF_NAME variable returns the full ref path, like refs/heads/branch-name. In include:rules, you might need to use if: $CI_COMMIT_REF_NAME =~ /main/ (not == main ). This behavior is resolved in GitLab 14.5.
