I've got a Drupal 8 site in dev that was put together with composer. I think I've got a solid grasp on the dependency injection bit although the details are murky. Now I want to deploy it to production but I've heard grave warnings that composer is not to be run on production. How can I deploy my Drupal to without it?
I've come across Acquia's BLT and it talks about building an artifact, maintaining it in a separate repo, and pulling that into production. I like the idea of generating a build artifact, but I'm not sure how to get one of those. I'm also not clear yet about how configuration is handled in that flow.
Update: This is our first Drupal 8 site. With D7 we'd settled on uploading a drush archive for the initial deploy and bash scripts for updates.
What I'd like is to pull the production repository and import configuration. Actually, my dream workflow would be to make a commit that triggers the testing and auto-deploy process. I'm struggling with the tooling for that though.
