Docker and plone
1 like2,822 views
This document discusses using Docker to deploy and manage Plone CMS installations. It begins by explaining what Docker is and how it provides isolated, consistent environments. It then compares installing and running Plone without Docker versus with Docker. With Docker, the process is simplified and the same environment can be easily replicated. The document also covers developing Plone add-ons within Docker containers, debugging, managing data volumes, running ZEO clusters, extending Docker images, and using Docker Compose and Rancher for orchestration and continuous deployment.
