Add feature to import/export docker containers
Currently Plesk allows only create Docker containers from the scratch, however in case customers move whole their infrastructure to server with Plesk there is no official way to transfer Docker containers from source environment. This feature related to https://plesk.uservoice.com/forums/184549-feature-suggestions/suggestions/40331437-add-docker-containers-to-plesk-migrator
The Docker extension allows you to "Save as Image" existing containers and to "Upload image" to Docker if you have images saved locally.
Plesk now supports launching a Portainer container. Portainer is container management software that makes it easier to manage Docker containers. It also allows you to export from Docker and import images to Docker. We would love to hear your feedback on our forum at https://talk.plesk.com.
