GitLab AI Gateway

The AI gateway is a standalone service that gives access to AI-powered GitLab Duo features.

Install the GitLab AI Gateway

Install by using Docker

Prerequisites:

  • Install a Docker container engine, such as Docker.
  • Use a valid hostname accessible within your network. Do not use localhost.

The GitLab AI Gateway Docker image contains all necessary code and dependencies in a single container.

Find the AI Gateway release

Find the GitLab official Docker image at:

Use the image tag that corresponds to your GitLab version. For example, if the GitLab version is v17.5.0, use self-hosted-v17.5.0-ee tag.

Start a container from the image

For Docker images with version self-hosted-17.4.0-ee and later, run the following:

docker run -p 5052:5052 \
 -e AIGW_GITLAB_URL=<your_gitlab_instance> \
 -e AIGW_GITLAB_API_URL=https://<your_gitlab_domain>/api/v4/ \
 <image>

From the container host, accessing http://localhost:5052/docs should open the AI Gateway API documentation.

Install by using the AI Gateway Helm chart

Prerequisites:

  • You must have a:
    • Domain you own, that you can add a DNS record to.
    • Kubernetes cluster.
    • Working installation of kubectl.
    • Working installation of Helm, version v3.11.0 or later.

For more information, see Test the GitLab chart on GKE or EKS.

Add the AI Gateway Helm repository

Add the AI Gateway Helm repository to Helm’s configuration:

helm repo add ai-gateway \
https://gitlab.com/api/v4/projects/gitlab-org%2fcharts%2fai-gateway-helm-chart/packages/helm/devel

Install the AI Gateway

  1. Create the ai-gateway namespace:

    kubectl create namespace ai-gateway

  2. Generate the certificate for the domain where you plan to expose the AI Gateway.

  3. Create the TLS secret in the previously created namespace:

    kubectl -n ai-gateway create secret tls ai-gateway-tls --cert="<path_to_cert>" --key="<path_to_cert_key>"

  4. For the AI Gateway to access the API, it must know where the GitLab instance is located. To do this, set the gitlab.url and gitlab.apiUrl together with the ingress.hosts and ingress.tls values as follows:

    helm repo add ai-gateway \
  https://gitlab.com/api/v4/projects/gitlab-org%2fcharts%2fai-gateway-helm-chart/packages/helm/devel
helm repo update

helm upgrade --install ai-gateway \
  ai-gateway/ai-gateway \
  --version 0.1.1 \
  --namespace=ai-gateway \
  --set="image.tag=<ai-gateway-image>" \
  --set="gitlab.url=https://<your_gitlab_domain>" \
  --set="gitlab.apiUrl=https://<your_gitlab_domain>/api/v4/" \
  --set "ingress.enabled=true" \
  --set "ingress.hosts[0].host=<your_gateway_domain>" \
  --set "ingress.hosts[0].paths[0].path=/" \
  --set "ingress.hosts[0].paths[0].pathType=ImplementationSpecific" \
  --set "ingress.tls[0].secretName=ai-gateway-tls" \
  --set "ingress.tls[0].hosts[0]=<your_gateway_domain>" \
  --set="ingress.className=nginx" \
  --timeout=300s --wait --wait-for-jobs

This step can take will take a few seconds in order for all resources to be allocated and the AI Gateway to start.

Wait for your pods to get up and running:

kubectl wait pod \
  --all \
  --for=condition=Ready \
  --namespace=ai-gateway \
  --timeout=300s

When your pods are up and running, you can set up your IP ingresses and DNS records.

Upgrade the AI Gateway Docker image

To upgrade the AI Gateway, download the newest Docker image tag.

  1. Stop the running container:

    sudo docker stop gitlab-aigw

  2. Remove the existing container:

    sudo docker rm gitlab-aigw

  3. Pull and run the new image.

  4. Ensure that the environment variables are all set correctly.
