Where are runners GitLab?
View and manage group runners You can do this for your self-managed GitLab instance or for GitLab.com. You must have the Owner role for the group. On the top bar, select Main menu > Groups and find your group. On the left sidebar, select CI/CD > Runners.
How many GitLab runners do I need?

Is GitLab runner free?
Free features: 10GB transfer per month [2] 400 CI/CD minutes per month. 5 users per namespace [4]
What is GitLab runner AWS?
gitlab-ci. yml file describing a pipeline's jobs, and a Gitlab Runner, an application that executes the pipeline jobs. Setting up the Gitlab Runner is a time-consuming process. It involves provisioning the necessary infrastructure, installing the necessary software to run pipeline workloads, and configuring the runner.
What is the difference between GitLab and GitLab runner?
Groups in GitLab are like organizations in GitHub. Individual users can be members of groups, and groups can have projects. From the perspective of a GitLab instance user, a GitLab Runner is a worker machine that executes your project's GitLab CI jobs, through work stealing.
How do I create a GitLab runner?
On gitlab, go to settings,CI/CD, and expand the “runners” option. You should see something like this: On the left hand side, you will get a token that you have to use to register your custom runner for this project.
What is CI and CD in GitLab?
GitLab CI (Continuous Integration) service is a part of GitLab that build and test the software whenever developer pushes code to application. GitLab CD (Continuous Deployment) is a software service that places the changes of every code in the production which results in every day deployment of production.
Can you have multiple GitLab runners?
It's possible to run multiple GitLab runners on the same host by encapsulating the runner and its executor dependencies inside a container. For example, since I use GitLab with the Docker executor, I created a container that encapsulates the GitLab runner + a docker engine.
What is pipeline in GitLab?
Pipeline as code is a practice of defining deployment pipelines through source code, such as Git. Pipeline as code is part of a larger “as code” movement that includes infrastructure as code. Pipeline as code is a practice of defining deployment pipelines through source code, such as Git.
Does GitLab runner use SSH?
SSH keys when using the Shell executor If you are using the Shell executor and not Docker, it is easier to set up an SSH key. You can generate the SSH key from the machine that GitLab Runner is installed on, and use that key for all projects that are run on this machine.
What is GitLab runner vs Jenkins?
Both Jenkins and Gitlab are designed to serve different requirements. While Jenkins boasts of a large plugin shelf, Gitlab is a comprehensive DevOps tool. While multiple plugins do your job efficiently, integration and management of these plugins might become a challenge when the project scales up.
How does GitLab communicate with runner?
GitLab and the Runners only communicate through an API using the https protocol, so the only requirement is that the Runner's host machine has network access to the GitLab instance.
Can you have multiple GitLab runners?
It's possible to run multiple GitLab runners on the same host by encapsulating the runner and its executor dependencies inside a container. For example, since I use GitLab with the Docker executor, I created a container that encapsulates the GitLab runner + a docker engine.
Why GitLab runner is needed?
GitLab runner is a build instance which is used to run the jobs over multiple machines and send the results to GitLab and which can be placed on separate users, servers, and local machine. You can register the runner as shared or specific after installing it.
How much RAM do I need for GitLab runner?
You need at least 2GB of addressable memory (RAM + swap) to install and use GitLab! With less memory GitLab will give strange errors during the reconfigure run and 500 errors during usage. 512MB RAM + 1.5GB of swap is the absolute minimum but we strongly advise against this amount of memory.
Can GitLab runner run multiple jobs?
One way to allow more jobs to run simultaneously is to simply register more runners. Each installation of GitLab Runner can register multiple distinct runner instances. They operate independently of each other and don't all need to refer to the same coordinating server.
How to Install GitLab Runner?
Below we have installed gitlab runner on the Linux system . Below are the steps to install gitlab runner on Linux system as follows:
What is a gitlab runner?
Basically, gitlab runner is the instance which was used to run our job in multiple machines after running the job we have sending it to gitlab. Also, we have sent the result across servers, local machines and the users which were separated. We can register it after installing as specific or we can also register as shared. We can serve our jobs by using shared or specific runners.
Can you run multiple jobs concurrently in gitlab?
Using gitlab runner we can run multiple jobs concurrently.
When installing PowerShell, do you need to give the executable command?
At the time of installing using PowerShell, we need to give the executable command.
Can we run a job using Docker?
We can run the job using the docker container by using it.
Do you have to restart gitlab?
Using it we can automatically configure the gitlab. We have no need to take a restart after configuring.
What does gitlab do?
Every push, merge and pull request emit events. Gitlab listens for it and starts the runner. This is nearly all CI/CD tools do like Github Action, Jenkins and other.
What is the meaning of "back up"?
Making statements based on opinion; back them up with references or personal experience.
Can a runner run a stff file?
If you use docker as the executor you can pull any image from docker hub or your configured registry and you can do loads of stff with docker images. In a docker environment normally you run them as the root user. https://docs.gitlab.com/runner/executors/README.html
Can a runner change CI_PROJECT_DIRdefined?
Yes. Every task executed by runner is relativly to CI_PROJECT _DIRdefined in https://gitlab.com/help/ci/variables/README. But you can alter this behaviour.
How do I know which runner I am currently using?
Many people are using GitLab CI but don't know exactly what happens behind the scenes. If you don’t know where your jobs are running and which types of executors you are using here is what you need to do.
Shell executor
This executor is running the jobs directly on the machine where the runner has been installed. It is as simple as it sounds. This is more or less similar to how Jenkins would run a job by default.
SSH executor
The SSH executor allows you to send commands over SSH to a machine. This executor is very similar in principle to the Shell executor. However, it works only for Bash scripts.
Docker executor
The Docker container to be used will be defined in the pipeline. This allows for a very simple run environment. This works fine on essentially any operating system, including Windows (with the docker-windows executor).
Docker Machine executor
In terms of how jobs are executed, the Docker Machine executor is not that much different from the Docker executor. The focus on this executor type is in the autoscaling capability.
Kubernetes executor
Using this executor makes sense if you already are using Kubernetes and understand its implications.
Conclusion
I hope this overview helped you get an idea of which GitLab executor you need. I have composed this based on my own experiences and research.
