You can set up a vmr environment to use it in CI/CD pipelines.
Once you set up your vmr environment take a snapshot of it.
Then you can get the command to run, to add it as a GitLab Runner:
virtualboxGitlabRunner(vmr_env,
gitlab_url = "gitlab.com",
gt_token = "<mytoken>",
snapshot_name = "cicdversionR",
vm_name = <VirtualBox VM Name>)
Copy and paste the return command in a terminal where GitLab Runner and the vmr environment are installed.
