Manage volumes: file trees stored once and mounted into models, training jobs, and Loops. For concepts and end-to-end workflows, see Volumes. A volume holds versions. A version is an immutable file tree addressed by digest. A tag is a mutable name pointing at a version. These commands address volumes positionally, the way filesystem commands address paths, so ‘ls’, ‘stat’, ‘cat’, and ‘rm’ read at whatever level of the tree the ref names. A ref is ‘bdn:namespace/volume’, with an optional ‘:tag’ or ‘@digest’ selector and trailing path, as in ‘bdn:weights/llama:prod/config/model.json’. The ‘bdn:’ is required; with no selector, the volume’s head is used. A digest may be written with or without its ‘b3:’ prefix, and shortened to 12 or more hex characters.

​
ls

Lists what a ref contains. With no ref, lists the namespaces holding volumes your API key can read. A namespace ref lists its volumes. A volume or version ref lists that version’s file entries, and a trailing path narrows to the entries under it, matched on slash boundaries so ‘config’ does not also match ‘configuration.json’. Entry listings show immediate children, with directory names and no aggregate size. Pass —recursive for the flat list of everything beneath. A ref is ‘bdn:namespace/volume’, with an optional ‘:tag’ or ‘@digest’ selector and trailing path, as in ‘bdn:weights/llama:prod/config/model.json’. The ‘bdn:’ is required; with no selector, the volume’s head is used. A digest may be written with or without its ‘b3:’ prefix, and shortened to 12 or more hex characters.

List everything under a directory of a tagged version

​
Filter output with --jq

Print the path of every file in a version

​
Output

Text mode (--output text): For entries, a table with columns: NAME, KIND, MODE, SIZE, MODIFIED, where a directory’s name ends in ’/’ and carries no size. For namespaces, one column: NAMESPACE, with refs such as bdn:weights. JSON keeps bare namespace names. For volumes, a table with columns: NAME, TAGS, HEAD SIZE, VERSIONS, EXPIRES, UPDATED. An expiring tag is annotated with its expiry. Prints what was empty to stderr when a listing has no rows. JSON mode (--output json): payload type cmd.VolumeEntryList. An object with version_ref and items, one entry per row, when the ref names a volume or a version. The two inventory shapes follow.

​
stat

Describes what a ref names. A volume ref describes the volume: its tags, head, version counts, and scheduled expiry. A version ref describes that version: its digest, size, entry count, lifecycle timestamps, and when it was created. A ref with a trailing path describes that one entry. A namespace ref is an error, since a namespace has nothing to describe beyond the volumes ‘ls’ already lists. A ref is ‘bdn:namespace/volume’, with an optional ‘:tag’ or ‘@digest’ selector and trailing path, as in ‘bdn:weights/llama:prod/config/model.json’. The ‘bdn:’ is required; with no selector, the volume’s head is used. A digest may be written with or without its ‘b3:’ prefix, and shortened to 12 or more hex characters.

​
Filter output with --jq

Print the digest of the version head points at, to pin a config.yaml to it

​
Output

Text mode (--output text): One field per line, describing the volume, the version, or the entry. JSON mode (--output json): payload type managementapi.Volume. The volume, when the ref names one with no selector. The two other shapes follow.

​
cat

Writes one file’s bytes to stdout, so it can be piped or redirected. The ref must carry a path naming a file: a ref naming a volume or a version has no single file to write, and a path naming a directory is an error. Chunks are verified against the digests the version records before they are written, so a truncated or corrupted read fails rather than producing partial output that looks complete. A file’s bytes have no JSON form, so ‘—output json’ and ‘—jq’ are rejected here. A ref is ‘bdn:namespace/volume’, with an optional ‘:tag’ or ‘@digest’ selector and trailing path, as in ‘bdn:weights/llama:prod/config/model.json’. The ‘bdn:’ is required; with no selector, the volume’s head is used. A digest may be written with or without its ‘b3:’ prefix, and shortened to 12 or more hex characters. Use --chunk-operations and --max-in-flight-mib to control download concurrency and memory.

Save a file from a tagged version under a different name

​
Output

Text mode (--output text): The file’s bytes, exactly as the volume holds them. JSON mode (--output json): payload type cmd.JSONUndefined.

​
push

Publishes DIR as a new version of the volume REF names, creating the volume if it does not exist. Only content the volume does not already hold is uploaded, so pushing a tree that mostly matches an existing version transfers only what differs. Nothing is visible until the whole tree has been uploaded, so an interrupted push publishes nothing, and what it did upload is not wasted. The ref may name a volume or a tag to apply to the new version, which is the same as passing that tag to —tag. A digest or a path is an error. A ref is ‘bdn:namespace/volume’, with an optional ‘:tag’ or ‘@digest’ selector and trailing path, as in ‘bdn:weights/llama:prod/config/model.json’. The ‘bdn:’ is required; with no selector, the volume’s head is used. A digest may be written with or without its ‘b3:’ prefix, and shortened to 12 or more hex characters.

​
TEXT

​
TEXT (repeatable)
Tag to apply to the new version at commit. May be repeated, and adds to a tag written on REF.

​
Examples

​
Filter output with --jq

Print the ref of the published version, which is what config.yaml takes

​
Output

Text mode (--output text): A summary of what was published: the version ref and digest, the file and byte counts, how many chunks were uploaded, and any tags applied. Transfer progress goes to stderr. JSON mode (--output json): payload type cmd.VolumePushResult.

​
pull

Downloads what REF names into DIR. A volume or version ref pulls the whole tree; a trailing path pulls that subtree or that one file. DIR is always a directory, and entries land at their volume-relative path under it, so pulling ‘bdn:weights/llama/config/model.json’ into ’./out’ writes ’./out/config/model.json’. Pass —strip-prefix to drop the path the ref named, writing ’./out/model.json’ instead. Every chunk is verified against the digest the version records before it is written, and an interrupted download picks up where it stopped. A ref is ‘bdn:namespace/volume’, with an optional ‘:tag’ or ‘@digest’ selector and trailing path, as in ‘bdn:weights/llama:prod/config/model.json’. The ‘bdn:’ is required; with no selector, the volume’s head is used. A digest may be written with or without its ‘b3:’ prefix, and shortened to 12 or more hex characters.

​

​
BOOL

​
TEXT (repeatable)
Restrict the download to this path in the volume, either a file or a directory whose contents are wanted, matched on slash boundaries. May be repeated, and is relative to the version’s root whatever path the ref carries. One that matches nothing fails the download.

​
BOOL

​
BOOL
Write the contents of the directory the ref names directly into DIR, instead of under the path that led to them. Requires a path on the ref.
​
INTEGER
Maximum object operations in flight, honored exactly. Defaults to a count the transfer adapts to what the service will bear.
​
BOOL

​
Examples

​
Filter output with --jq

Print how many files were written

​
Output

Text mode (--output text): A summary of what was written: the version ref and digest, the destination, and the file and byte counts. Transfer progress goes to stderr. JSON mode (--output json): payload type cmd.VolumePullResult.

​
rm

Deletes what REF names. A ref carrying a digest deletes that version. A volume ref deletes every live version of the volume and requires —recursive, so a ref that meant to name one version cannot take the whole volume with it. A deleted version is recoverable with ‘volume restore’ for a limited window, which the output reports. A tag reference is an error because it would delete the version the tag points at. Use tag delete to delete only the tag. A path is an error because versions are immutable. A ref is ‘bdn:namespace/volume’, with an optional ‘:tag’ or ‘@digest’ selector and trailing path, as in ‘bdn:weights/llama:prod/config/model.json’. The ‘bdn:’ is required; with no selector, the volume’s head is used. A digest may be written with or without its ‘b3:’ prefix, and shortened to 12 or more hex characters.

​
BOOL

​
Examples

Delete one version
Delete every live version of a volume, without prompting

​
Filter output with --jq

Print when the deleted version stops being restorable

​
Output

Text mode (--output text): One field per line: what was deleted and until when it can be restored. Prompts for confirmation first unless —yes is passed. JSON mode (--output json): payload type managementapi.DeleteVolumeVersionResponse. The deleted version, when the ref names one. The whole-volume shape follows.

​
versions

Lists a volume’s versions, newest first, with the digest, sequence, size, lifecycle, tags, scheduled expiry, and which one head points at. The ref must name a volume: a selector or a path names one point in the history rather than the history itself. A ref is ‘bdn:namespace/volume’, with an optional ‘:tag’ or ‘@digest’ selector and trailing path, as in ‘bdn:weights/llama:prod/config/model.json’. The ‘bdn:’ is required; with no selector, the volume’s head is used. A digest may be written with or without its ‘b3:’ prefix, and shortened to 12 or more hex characters.

Examples

List a volume’s versions

​
Filter output with --jq

Print the digest of every tagged version

​
Output

Text mode (--output text): Table with columns: SEQUENCE, DIGEST, SIZE, LIFECYCLE, HEAD, TAGS, EXPIRES, CREATED. When the volume has no versions, prints “No volume versions found.” to stderr. JSON mode (--output json): payload type managementapi.ListVolumeVersionsResponse.

​
restore

Restores a deleted version during its recovery window, which ‘volume rm’ reports and ‘volume versions —include-tombstoned’ lists. The ref must carry a digest, since deleting a version drops the tags that pointed at it, so a tag no longer names one. A ref is ‘bdn:namespace/volume’, with an optional ‘:tag’ or ‘@digest’ selector and trailing path, as in ‘bdn:weights/llama:prod/config/model.json’. The ‘bdn:’ is required; with no selector, the volume’s head is used. A digest may be written with or without its ‘b3:’ prefix, and shortened to 12 or more hex characters.

​
Filter output with --jq

Print the lifecycle state the version came back in

​
Output

Text mode (--output text): One field per line, describing the restored version. JSON mode (--output json): payload type managementapi.RestoreVolumeVersionResponse.

​
tag set

Create a tag or move it to an existing version. Omitting --expires-at clears any expiration time already set on the tag. Version or volume expiration still removes the tag.
The reference can select a version by tag or digest. Without a selector, it selects head. A path is invalid. Setting head requires confirmation and changes what references without a selector resolve to. You can’t give head an expiration time or point it at an expiring version.
​
TEXT
Time at which the tag expires, as an RFC 3339 date-time with a UTC offset, as in 2030-01-01T00:00:00Z. It must be in the future and at most ten years ahead. Omit it for a tag that does not expire. Omitting it on an existing tag clears its expiration time.
​
BOOL
Write refs with the whole digest instead of shortening it to 12 hex characters.

​
BOOL
Skip confirmation for ‘head’. Required when stdin is not a terminal and —tag is ‘head’.
​
BOOL
Enable verbose logging
The result includes the version reference, tag, digest, expiration time, and volume sequence.

​
tag delete

Remove a tag without deleting its version:
The volume reference must have no selector or path. Deleting a missing tag succeeds with deleted set to false. Deleting head requires confirmation and prevents references without a selector from resolving until you set head again.

​
BOOL
Skip confirmation for ‘head’. Required when stdin is not a terminal and —tag is ‘head’.
​
BOOL
Enable verbose logging
The result includes the tag, whether it was deleted, and the volume sequence.

​
update

Set or clear the expiration time for an entire volume. When it expires, every live version is deleted, every tag is removed, and the volume disappears from listings. Clearing expiration afterward doesn’t restore deleted versions. Each version remains restorable until its recovery deadline.
To cancel scheduled expiration, run:
The reference must name a volume without a selector or path. Exactly one expiration option is required. Both operations prompt for confirmation unless you pass --yes.
​
BOOL
Clear the volume’s expiration time.Mutually exclusive with other flags in group expiration.
​
