Command: volume snapshot list

The volume snapshot list command lists volume snapshots known to a Container Storage Interface (CSI) storage provider. Only CSI plugins that implement the Controller interface support this command.

Usage

nomad volume snapshot list [-plugin plugin_id -secrets key=value]

The volume snapshot list command returns a list of snapshots along with their source volume ID as known to the external storage provider. This is not the same as the Nomad volume ID, as the source volume may not be registered with Nomad.

General Options

  • -address=<addr>: The address of the Nomad server. Overrides the NOMAD_ADDR environment variable if set. Defaults to http://127.0.0.1:4646.

  • -region=<region>: The region of the Nomad server to forward commands to. Overrides the NOMAD_REGION environment variable if set. Defaults to the Agent's local region.

  • -namespace=<namespace>: The target namespace for queries and actions bound to a namespace. Overrides the NOMAD_NAMESPACE environment variable if set. If set to '*', job and alloc subcommands query all namespaces authorized to user. Defaults to the "default" namespace.

  • -no-color: Disables colored command output. Alternatively, NOMAD_CLI_NO_COLOR may be set. This option takes precedence over -force-color.

  • -force-color: Forces colored command output. This can be used in cases where the usual terminal detection fails. Alternatively, NOMAD_CLI_FORCE_COLOR may be set. This option has no effect if -no-color is also used.

  • -ca-cert=<path>: Path to a PEM encoded CA cert file to use to verify the Nomad server SSL certificate. Overrides the NOMAD_CACERT environment variable if set.

  • -ca-path=<path>: Path to a directory of PEM encoded CA cert files to verify the Nomad server SSL certificate. If both -ca-cert and -ca-path are specified, -ca-cert is used. Overrides the NOMAD_CAPATH environment variable if set.

  • -client-cert=<path>: Path to a PEM encoded client certificate for TLS authentication to the Nomad server. Must also specify -client-key. Overrides the NOMAD_CLIENT_CERT environment variable if set.

  • -client-key=<path>: Path to an unencrypted PEM encoded private key matching the client certificate from -client-cert. Overrides the NOMAD_CLIENT_KEY environment variable if set.

  • -tls-server-name=<value>: The server name to use as the SNI host when connecting via TLS. Overrides the NOMAD_TLS_SERVER_NAME environment variable if set.

  • -tls-skip-verify: Do not verify TLS certificate. This is highly not recommended. Verification will also be skipped if NOMAD_SKIP_VERIFY is set.

  • -token: The SecretID of an ACL token to use to authenticate API requests with. Overrides the NOMAD_TOKEN environment variable if set.

Snapshot List Options

  • -page-token: Where to start pagination.
  • -per-page: How many results to show per page.
  • -plugin: Display only snapshots managed by a particular CSI plugin. This flag is required and accepts a plugin ID or prefix. If there is an exact match based on the provided plugin, then that specific plugin will be queried. Otherwise, a list of matching plugins will be displayed.
  • -secret: Secrets to pass to the plugin to list snapshots. Accepts multiple flags in the form -secret key=value
  • -verbose: Display full information for the resulting snapshot.

When ACLs are enabled, this command requires a token with the csi-list-volumes capability for the plugin's namespace.

Examples

List volume snapshots for a plugin:

$ nomad volume snapshot list -plugin aws-ebs0
Snapshot ID  External ID  Size   Creation Time         Ready?
snap-12345   vol-abcdef   50GiB  2021-01-03T12:15:02Z  true
snap-67890   vol-fedcba   50GiB  2021-01-04T15:45:00Z  true

List volume snapshots with two secret key/value pairs:

$ nomad volume snapshot list -plugin aws-ebs0 -secret key1=value1 -secret key2=val2
Snapshot ID  External ID  Size   Creation Time         Ready?
snap-12345   vol-abcdef   50GiB  2021-01-03T12:15:02Z  true
