Server-Side GTM Docker Setup

I need a fully working server-side Google Tag Manager instance deployed inside my existing Docker environment. Once the container is live, it must forward events to Google ADS, GA4, and Facebook so I can handle conversion reporting through each platform’s API instead of the browser.

Current state
– WooCommerce shop already running
– A standard web GTM container exists that only holds a few custom variables; no server container yet
– One crucial event to capture is a specific form submission (not a purchase) in addition to the usual e-commerce events that GA4 already collects client-side

What I need from you
• Spin up and configure the GTM server container inside my Docker stack (Ubuntu host)
• Link the server container with my existing web container using the recommended tagging template
• Migrate my existing variables so they resolve exactly as they do now
• Set up server-side forwarding for Google ADS, GA4, and Facebook, including the Facebook Conversion API token configuration
• Implement and test the form-submission trigger so it fires cleanly through the server container

Acceptance
I’ll consider the job complete when the GTM server container is reachable, events for Google ADS, GA4, and Facebook appear in their respective real-time debuggers, and the form submission shows the correct payloads in all three platforms.

If you have solid experience with server-side GTM, Docker, and WooCommerce, let’s make this happen.
