What is a runner in GitLab

What is a runner in GitLab?

This tutorial shows you how to configure and run your first runner in GitLab. A runner is an agent in the GitLab Runner application that runs jobs in a GitLab CI/CD pipeline. Jobs are defined in the . gitlab-ci. yml file and assigned to available runners.

What is the difference between GitLab agent and runner?

The runner is about hosting gitlab-ci pipelines and the agent is about operating your environments. See the two workflows for connecting your cluster to gitlab. In the latter case you still need some way to run your CI pipelines, even though the deployment is handled by the agent.

What is the difference between pipeline and runner in GitLab?

Pipeline: A collection of jobs split into different stages. Runner: An agent or server that executes each job individually that can spin up or down as needed. Stages: A keyword that defines certain stages of a job, such as build and deploy .

Why is GitLab runner needed?

These runners are useful to deploy a certain project, if jobs have certain requirements or specific demand for the projects. Specific runners use FIFO (First In First Out) process for organizing the data with first-come first-served basis. You can register a specific runner by using project registration token.

Is GitLab runner same as Jenkins?

No. GitLab and Jenkins are two popular tools used for continuous integration and continuous development/deployment features. They both offer their own set of pros and cons which are discussed in this post. None of the tools takes the help of another; they work independently.

Is GitLab Runner free?

Most of GitLab functionality is and will be available for free in our Free tier. Our paid tiers include features that are more relevant for managers, directors, and executives. We promise all major features in our scope are available in Free too.

How many GitLab runners do I need?

You can have one gitlab runner for all stages. The build job would then be picked up by any gitlab runner that you have defined that has the tag build .

Are GitLab runners safe?

High-security risks exist to your runner host and network when running builds with the shell executor. The jobs are run with the permissions of the GitLab Runner’s user and can steal code from other projects that are run on this server. Use it only for running trusted builds.

How does GitLab decide which runner to use?

As such GitLab doesn’t choose. All of the active runners check regularly (I don’t remember the interval, but it’s less than one minute by default) if there are jobs they should handle (by tags mostly), and if there is, they pick up the job.

What is the difference between GitLab Runner and GitHub Actions?

Runners are machines on which the jobs run. Both GitLab CI/CD and GitHub Actions offer managed and self-hosted variants of runners. In GitLab CI/CD, tags are used to run jobs on different platforms, while in GitHub Actions it is done with the runs-on key.

Can we use same GitLab runner for multiple projects?

Shared runners are available to every project in a GitLab instance. Use shared runners when you have multiple jobs with similar requirements. Rather than having multiple runners idling for many projects, you can have a few runners that handle multiple projects.

Why is GitLab-runner slow?

In conclusion, GitLab can be slow for various reasons, including the size of the code repository, the complexity of the CI/CD pipelines, and the performance of the runners. By using Git shallow clones, parallel jobs, caching, faster runners and a CDN, you can speed up GitLab CI and build fast pipelines.

What is the best CI CD tool?

Best CI/CD Tools Github Actions Icon. Circle CI Icon. Jenkins Icon. Travis CI Icon. Bitbucket Pipeline Icon. TeamCity Icon. Semaphore Icon. Harness Icon. 更多項目…

How does GitLab-runner connect?

Runners communicate with GitLab over HTTPS, entirely through connections initiated from the Runner to GitLab and never in reverse. The advantage here is that you can install a Runner behind a firewall and as long as the Runner has outbound access to GitLab.com it will work.
