GitLab - install and configure using Docker

Before installing, review the prerequisites and the general instructions for installation using Docker.

This integration is useful to ensure a secure connection with your on-premise or cloud GitLab deployment.

Configure Broker to be used for GitLab

To use the Broker client with GitLab.com or an on-prem GitLab deployment, run docker pull snyk/broker:gitlab. Refer to GitLab - environment variables for Snyk Broker for definitions of the environment variables.

If necessary, go to the Advanced configuration page and make any configuration changes needed, such as providing the CA (Certificate Authority to the Broker Client configuration if the GitlLab instance is using a private certificate, or setting up proxy support.

Docker run command to set up a Broker Client for GitLab

Copy the following command to set up a fully configured Broker Client to analyze Open Source, IaC, Container, Code files, and Snyk AppRisk information. Enable Snyk AppRisk to identify your application assets, monitor them, and prioritize the risks.

docker run --restart=always \
           -p 8000:8000 \
           -e BROKER_TOKEN=<secret-broker-token> \
           -e GITLAB_TOKEN=<secret-gitlab-token> \
           -e GITLAB=<your.gitlab.domain.com (no http/s)> \
           -e PORT=8000 \
           -e BROKER_CLIENT_URL=<http://broker.url.example:8000 (dns/IP:port)> \
           -e ACCEPT_IAC=tf,yaml,yml,json,tpl \
           -e ACCEPT_CODE=true \
           -e ACCEPT_APPRISK=true \
       snyk/broker:gitlab

Use the environment variable REMOVE_X_FORWARDED_HEADERS=true to remove the XFF headers from the requests made by the Broker client to GitLab. This allows the Broker to work properly.

Snyk AppRisk is set by default to false. Enable it by setting the flag to true.

As an alternative to using the Docker run command, you can use a derived Docker image to set up the Broker Client integration. See Derived Docker images for the environment variables to override for the GitLab integration.

Start the Broker Client container and verify the connection with GitLab

Paste the Broker Client configuration to start the Broker Client container.

Once the container is up, the GitLab Integrations page shows the connection to GitLab and you can Add Projects.

Basic troubleshooting for Broker with GitLab

• Run docker logs <container id> to look for any errors, where container id is the GitLab Broker container ID.

• Ensure relevant ports are exposed to GitLab.
