Google Tag Manager now offers the ability to host your own server-side instances. This helps with some third-party vs first-party cookie concerns.
In its current state, the google_tag module only supports GTM hosted at www.googletagmanager.com.
Proposed resolution
Add a gtm_hostname property to all containers and initialize the default value to www.googletagmanager.com across all container instances to maintain parity with existing functionality.
Remaining tasks
Write the patchAdd screenshotsEnsure proper test coverage
User interface changes
Anywhere "Container ID" is present, we should also add "GTM Hostname"
API changes
None
Data model changes
All container instances now have a gtm_hostname property

Comment #4
WidgetsBurritos commentedOkay, those last two changes after changing the issue status were because I had missed committed the TestBase file and also removing an unrelated whitespace change that was mistakenly committed the first time around. This is now officially ready for review.

donal_obscurity commentedIs there anything I can do to help move this feature forward? I reviewed the code in GitLab and it seems fairly straightforward. LGTM.

Thanks to all.
Comment #15

Comment #17
solotandem commentedThanks to everyone with input.
Commit follows the merge request with some minor changes. The primary visual difference is adding the hostname to the advanced tab instead of the general tab.
Comment #19
roaldnel commentedWe have increasingly received requests from clients to add the script in a different format presumably constructed by GTM as such I have further updated the code changes that this issue brought about to apply this new format. The primary change can be found in lines 275 to 306 of the src/Entity/Container.php file. The rest of the changes were mainly cleaning up the code. I have attached a patch with the proposed changes, any input or improvements are welcome.
