GitLab Deployment

Description

GitLab deployment is required in Scenario 1 (openEuler native deployment CI/CD based on GitLab CI/CD). In Scenario 2 (openEuler native development cluster managed by GitLab CI/CD), skip this step.

Preparing the Server

Prepare a machine running openEuler 20.03 LTS or later versions.

Starting GitLab

Copy the required YAML files to the /home directory and start the related pod.

Note: The YAML files related to GitLab can be obtained from the GitLab official site.

Example YAML files are as follows. Modify them as required.
