Managing persistent storage is a challenge in any containerized environment, given the differing needs of applications. Portainer makes the provisioning and management of storage very straightforward for users.
Docker provisioning
From a provisioning perspective, Portainer supports the creation of persistent volumes against either a local path on a docker host, or a CIFS share, or a NFS mount.
Volume Browsing
Portainer provides authorized users with the ability to browse the persistent volumes attached to containers. Users can interact directly with the volume content, either uploading/downloading files, or renaming/deleting.
Kubernetes capacity management
In a Kubernetes environment, Portainer allows users to specify the maximum size of their requested volume when created. It then allows the administrator to expand the capacity allocated to their persistent volume. In addition, Portainer displays all volumes for a given backend storage type so as to visually show the allocated capacity.
