Portainer
Portainer hides the complexity of managing containers behind an easy-to-use UI. By removing the need to use the CLI, write YAML or understand manifests, Portainer makes deploying apps and troubleshooting problems so easy that anyone can do it.
It can be deployed and accessed directly from the Plesk Docker interface
Whilst Portainer itself is mature, Portainer is a beta feature within Plesk - there may be undocumented issues or limitations; please share your feedback!
