v2.21.0

v2.21.0 (Jan 6, 2026)

Breaking Changes

• When --tls-ca-cert-file is provided, only that CA is trusted (previously it was added to the system trust store)

Enhancements

• queues list now supports --columns for selecting specific columns to display:

  rabbitmqadmin queues list --columns name,queue_type,message_count
  
  rabbitmqadmin queues list --columns name

  Column names are case-insensitive. Unknown columns are silently ignored.

• queues show is a new command that displays select metrics of a single queue:

  rabbitmqadmin queues show --name "events.incoming"
  
  rabbitmqadmin queues show --name "orders.pending" --columns name,queue_type,message_count

• streams list now supports --columns for consistency with queues list:

  rabbitmqadmin streams list --columns name,queue_type

• streams show is a stream equivalent of queues show:

  rabbitmqadmin streams show --name "events.stream"
  
  rabbitmqadmin streams show --name "events.stream" --columns name,queue_type

• config_file is a new command group for operations on rabbitmqadmin configuration files:

  rabbitmqadmin config_file show_path
  
  # Show all configured nodes (passwords masked by default)
  rabbitmqadmin config_file show
  rabbitmqadmin config_file show --reveal-passwords
  
  # Add a new node (fails if an entry with this name already exists)
  rabbitmqadmin config_file add_node --node experiment-001 --host rabbit.eng.example.com --port 15672 --username admin --password secret --vhost /
  
  # Update an existing node (or create one if it does not exist).
  # Only the specified fields are updated; unspecified fields are preserved.
  rabbitmqadmin config_file update_node --node experiment-001 --host new-rabbit.eng.example.com --port 15673
  
  # Enable TLS for a node (other settings like username, password are preserved)
  rabbitmqadmin config_file update_node --node experiment-001 --use-tls --port 15671
  
  # Disable TLS for a node (other settings are preserved)
  rabbitmqadmin config_file update_node --node experiment-001 --scheme http --port 15672
  
  # Delete a node (a configuration file entry)
  rabbitmqadmin config_file delete_node --node experiment-001
