Resource relationships in Managed Service for GitLab

GitLab is an open-source web-based DevOps lifecycle tool. It is a code repository management system for Git with error tracking, CI/CD pipeline, dedicated Wiki, and other features.

Managed Service for GitLab helps configure application deployment on VMs in Yandex Compute Cloud and supports integration with Yandex Container Registry and Yandex Managed Service for Kubernetes.

How Managed Service for GitLab works:

GitLab instanceGitLab instance

A GitLab instance is the service's primary entity. It is a VM deployed in Yandex Cloud. Managed Service for GitLab takes care of its routine maintenance, such as storage fault tolerance, security updates, automated GitLab version upgrades, and so on.

Users can mange instances from the Yandex Cloud management console, CLI, and API.

Instance configurationInstance configuration

When creating an instance, you specify:

• Instance type: The number of vCPUs and the amount of RAM. Available instance types:

  Type	Computing resources
  s2.micro	2 vCPUs, 8 GB RAM
  s2.small	4 vCPUs, 16 GB RAM
  s2.medium	8 vCPUs, 32 GB RAM
  s2.large	16 vCPUs, 64 GB RAM

  After you create an instance, you can change its type to a higher performing one.

• Subnet.

  Warning

  For the time being, Yandex Cloud technical restrictions do not allow selecting a subnet with an address range of 192.168.0.0/24.

• Disk size. After you create an instance, you can increase its disk size.

• Name in the .gitlab.yandexcloud.net domain: Your GitLab instance's internet address.

• Administrator information:

  • Email.
  • Login.

GitLab RunnerGitLab Runner

GitLab Runner is an open-source application which executes GitLab CI/CD pipeline jobs based on instructions from a special file named .gitlab-ci.yml. It helps run automated builds in Managed Service for Kubernetes clusters and on Compute Cloud VMs.

You can get started with GitLab Runner in the following ways:

• Install GitLab Runner in a Managed Service for Kubernetes cluster.

• Create a Compute Cloud VM and install GitLab Runner on it manually.

• Use the management console to create a runner that will automatically deploy the specified number of Compute Cloud VMs.

  When creating a runner from the management console, you can select the following 15 to 500 GB disk types for the VM storage:

  • HDD
  • SSD

  The following computing resource configurations are available:

  • 2 vCPUs, 4 GB RAM
  • 2 vCPUs, 8 GB RAM
  • 4 vCPUs, 16 GB RAM
  • 8 vCPUs, 64 GB RAM
  • 16 vCPUs, 128 GB RAM

  Note

  The feature of creating and managing runners using the management console is at the Preview stage. To request access, contact support or your account manager.

GitLab PagesGitLab Pages

GitLab Pages is a tool for publishing static websites composed of files residing in a GitLab repository. Websites are deployed by GitLab CI/CD jobs. GitLab Pages works with static website generators and standard HTML, CSS, and JavaScript files.

GitLab Pages enables you to use your own domains and SSL/TLS certificates and to configure access to websites.

For more information, see the official GitLab documentation.
