How to install GitLab Runner on Kubernetes?

First, declare a new Namespace called gitlab-runner. After we create the new Namespace, we add the authentication roles to the Kubernetes cluster for the Runner. Below are the ServiceAccount, Role, and RoleBinding for the Runner. Copy this configuration into a file called gitlab-runner-service-account.

What is a runner in Kubernetes?

The Kubernetes runner is a standalone service that executes pipelines inside Pods. The Kubernetes runner is very similar to the Docker runner, and should be used when running Drone on Kubernetes.

What does a GitLab runner do?

In GitLab CI, Runners run your yaml. A runner is an isolated (virtual) machine that picks up builds through the coordinator API of GitLab CI. A runner can be specific to a certain project or serve any project in GitLab CI. A runner that serves all projects is called a shared runner.

What is the difference between gitlab agent and runner?

On gitlab it says an agent is used to connect to the cluster, run pipelines, and deploy applications. But with a regular runner you could just have a pipeline that invokes kubectl to interact with the cluster.

Can GitLab run in a container?

In a nutshell, GitLab services provide you a way to start additional Docker containers and to link them to your image (whatever you have specified in with the image keyword). One of the most typical use cases is when you need a database, an API, or some other service that you can call over the network.

Can I run GitLab in Docker?

Have you ever wanted to host your own GitLab repositories? With the help of both Ubuntu Server 22.04 and Docker, you can do just that.

Is Kubernetes used for CI CD?

The capabilities provided by Kubernetes help reduce the amount of time and effort required to deploy applications via a CI/CD pipeline. It provides an efficient model to monitor and control capacity demands and usage. Additionally, Kubernetes automates application management to reduce outages.

Is GitLab runner open-source?

Gitlab Runner is an application that works with GitLab CI/CD to run the job in a pipeline. It is open-source and written in Go Language. It can also be run inside the Docker container or it can be deployed into a Kubernetes cluster.

What is a Docker runner?

The Docker runner is a daemon that executes pipelines steps inside ephemeral Docker containers. You can install a single Docker runner, or install the Docker runner on multiple machines to create your own build cluster.

How do I use GitLab runner?

Go to the settings of a GitLab project that you want to use GitLab Runner for and obtain the registration token. In your GitLab repository, go to Settings --> CI/CD and expand the Runners section. From the Specific runners section, copy the registration token. Don't forget to disable Shared runners.

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 .

How many types of runners are there in GitLab?

In the GitLab UI there are three types of runners, based on who you want to have access: Shared runners are available to all groups and projects in a GitLab instance. Group runners are available to all projects and subgroups in a group. Specific runners are associated with specific projects.

How does Gitlab integrate with EKS?

Access GitLab Kubernetes Integration Page by clicking on the ”Kubernetes” menu for groups and Operations > Kubernetes menu for projects and click the “Add Kubernetes Cluster” button. Select “Amazon EKS” in the options provided under the “Create new cluster on EKS” tab.

What is a running pod?

Today Garmin announced a new accessory alongside the Forerunner 935, the Running Dynamics Pod. This tiny pod, about the size of a piece of small candy, essentially provides the existing Running Dynamics data (i.e. Vertical Oscillation/Ground Contact Time) that normally comes from the HRM-TRI/HRM-RUN units.

Can I add a container to a running pod?

Pods are the fundamental building block of Kubernetes applications. Since Pods are intended to be disposable and replaceable, you cannot add a container to a Pod once it has been created.

How do I know if my pod is running?

Using kubectl describe pods to check kube-system

If the output from a specific pod is desired, run the command kubectl describe pod pod_name --namespace kube-system . The Status field should be "Running" - any other status will indicate issues with the environment.

Does DAPR require Kubernetes?

Dapr can be configured to run on any supported versions of Kubernetes. To achieve this, Dapr begins by deploying the dapr-sidecar-injector , dapr-operator , dapr-placement , and dapr-sentry Kubernetes services. These provide first-class integration to make running applications with Dapr easy.

Is K3s compatible with K8s?

K3s is a lightweight, easy to install, deploy, and manage version of stock Kubernetes (K8s). No, it is not a fork of Kubernetes. K3s is a certified Kubernetes distribution. Although K3s is a refined version of Kubernetes (the upstream version), it does not change how Kubernetes works at its core.

Why do we use Dapr?

At its core, Dapr helps reduce the inherent complexity of distributed microservice applications. It's built upon a concept of building block APIs. Dapr building blocks expose common distributed application capabilities, such as state management, service-to-service invocation, and pub/sub messaging.
