This image shows the standalone architecture for deploying GitLab to enable CI/CD pipelines on OCI. It shows a single availability domain within an OCI region. Within this availability domain are a single public subnet with the address 10.0.0.0/24 and a private subnet addressed 10.0.1.0/24. A GitLab server resides within the public subnet while the private subnet contains three GitLab runners, which are connected to the GitLab server in the public subnet. All of these components are protected by a virtual cloud network (VCN). The GitLab server can access the cloud, outside the VCN, through an Internet Gateway; the runners in the private subnet access the cloud via a NAT gateway.
