portler volumes

Manage this project's Portler-managed Docker volumes. See the Volumes guide for concepts and the worktree workflow.

bash

portler volumes [list]
portler volumes fork <volume> <new-set>
portler volumes remove <volume> [--force]

All volume commands need the Docker daemon; when it is not running they fail with a clear error.

`volumes` / `volumes list`

Lists this project's volumes with their volume set, declaring services, size, and the containers using them.

Clones a volume's data into a <volume>--<new-set> variant:

bash

portler volumes fork postgres-data migration

The copy runs cp -a inside a throwaway alpine:3 container; the original is untouched.
<volume> can be the short name from portler.yml (postgres-data), a name--set variant (postgres-data--migration), or the full Docker volume name.
Set names may contain a-z0-9_.- but not --.

Run the stack against the fork with portler up --volume-set migration.

Removes a project volume. Portler refuses while a running container mounts it unless --force is passed.
