I made last week a small cheat sheet for #shopware 6 deployments. https://shopwaretherightway.com/docs/hosting/deployment/
Feel free to make a PR to add missing stuff 😀
Deployment

Deployment # Each Deployment looks different but some things are equals between multiple ways to deploy. This site list some best practises todo. Plugins # All Plugins should be managed by Composer. If you have project specific plugins you should put them into custom/static-plugins and require the plugin then or build them into the src directory without building a Plugin. You can refer also to this Blog Post if you want to customize Shopware without Plugins.
