Command: volume status
The volume status
command displays status information for Container
Storage Interface (CSI) volumes.
Usage
nomad volume status [options] [volume]
This command accepts an optional volume ID or prefix as the sole argument. If there is an exact match based on the provided volume ID or prefix, then information about the specific volume is queried and displayed. Otherwise, a list of matching volumes and information will be displayed.
If the ID is omitted, the command lists out all of the existing volumes and a few of the most useful status fields for each.
When ACLs are enabled, this command requires a token with the
csi-read-volume
and csi-list-volumes
capability for the volume's
namespace.
General Options
-address=<addr>
: The address of the Nomad server. Overrides theNOMAD_ADDR
environment variable if set. Defaults tohttp://127.0.0.1:4646
.-region=<region>
: The region of the Nomad server to forward commands to. Overrides theNOMAD_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 theNOMAD_NAMESPACE
environment variable if set. If set to'*'
, job and alloc subcommands query all namespacecs authorized to user. Defaults to the "default" namespace.-no-color
: Disables colored command output. Alternatively,NOMAD_CLI_NO_COLOR
may be set.-ca-cert=<path>
: Path to a PEM encoded CA cert file to use to verify the Nomad server SSL certificate. Overrides theNOMAD_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 theNOMAD_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 theNOMAD_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 theNOMAD_CLIENT_KEY
environment variable if set.-tls-server-name=<value>
: The server name to use as the SNI host when connecting via TLS. Overrides theNOMAD_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 ifNOMAD_SKIP_VERIFY
is set.-token
: The SecretID of an ACL token to use to authenticate API requests with. Overrides theNOMAD_TOKEN
environment variable if set.
Status Options
-type
: Display only volumes of a particular type. Currently only thecsi
type is supported, so this option can be omitted when querying the status of CSI volumes.-plugin_id
: Display only volumes managed by a particular CSI plugin.-short
: Display short output. Used only when a single volume is being queried. Drops verbose volume allocation data from the output.-verbose
: Show full information. Allocation create and modify times are shown inyyyy/mm/dd hh:mm:ss
format.
