List is used to list available quota specifications.

If ACLs are enabled, this command requires a token with the 'quota:read'
|
|
capability. Any quotas applied to namespaces that the token does not have
|
|
access to will be filtered from the results.

General Options:

` + generalOptionsUsage(usageOptsDefault) + `

|
|
List Options:
|
|
|
|
-json
|
|
Output the quota specifications in a JSON format.
|
|
