Configure Load Balancer for DT deployed on GCE

[spawar-apex]

Hi,

I have deployed Dependency track using docker compose (deploying on docker container) on a Google Compute Engine. Currently, I have used external ip (http protocol) of the Google Compute Engine (GCE VM) in CI/CD pipeline to upload BOM to the project in DT.

I would like to set an Global load balancer in GCP which has public IP with SSL configured (protocol https and port 443).

How would I configure docker compose (frontend + API backend) to use Load balancer URL. At the moment, both the API server & Frontend are hosted on Same VM so even If I configure Load balancer with SSL, how would I use the https domain in Github Actions.

Here is the Github Action used (From point 1):

- name: Upload BOM to Dependency-Track
        # You may pin to the exact commit or the version.
        # uses: DependencyTrack/gh-upload-sbom@5b797334a759f72f780daa0293681cf87a7d9929
        uses: DependencyTrack/gh-upload-sbom@v2.0.0
        continue-on-error: true
        with:
          # Dependency-Track hostname
          serverhostname: '<public_ip)'
          # Dependency-Track port
          port: 8081 # optional, default is 443
          # Dependency-Track protocol
          protocol: 'http' # optional, default is https
          # Dependency-Track API key
          apikey: ${{ secrets.APIKEY }}
          # Project in Dependency-Track
          project: '5948fff8-f26c-4248-876e-90748d832ac8' # optional
          # Project name in Dependency-Track
          projectname: 'source_monorepo' # optional
          # Project version in Dependency-Track
          autoCreate: true
          projectversion: 'v1'   # optional
          # Path and filename of the BOM
          bomfilename: /tmp/sbom.cyclonedx.json # optional, default is bom.xml

Can I deploy Frontend & API Server on Seperate VM's?

Also, How can I use the subdomain that is mapped to external IP of VM (that runs both the components)?

Any guidance would be appreciated. Thanks!

I don't fully understand the question. If you have the containers running and the load balancer can reach them, you can configure the loadbalancer to proxy https://deptrack.spawar.com to the frontend container and proxy https://deptrack.spawar.com/api to the api container. Then use https://deptrack.spawar.com as API_BASE_URL and in your GH action.

Hi @valentijnscholten , Thank for sharing the details. I was able to configure load balancer to reach the container running on VM.
Now, I'm able to access the domain however when I enter the creds, its throwing an error 405 METHOD NOT ALLOWED.

Do I need to set headers in docker-compose.yaml?

Can you help me to understand the error? What's causing the issue?

@valentijnscholten - Apologies for reaching out on multiple platforms. I was bale to resolve the issue which has happened at the Load Balancer level.
