Magento 2 module for Zero downtime deployment.

Module prevents showing database versions exception when you pull new code to the server. The best idea is to use CI/CD with Docker/Kubernetes. Suggested deployment:

• get docker base image
• run php bin/magento setup:upgrade on destination database
• run php bin/magento setup:di:compile and php bin/magento setup:static-content:deploy on build container
• deploy new container

NOTICE: If new version contain new classes (for example in EAV) or changed logic, Magento could behave unpredictable. You are using this module at your own risk!
