Import/Export definitions
The LavinMQ definitions file consist of users, queues, exchanges, bindings, virtual hosts, permissions, and parameters. These definitions can be exported to a file to import into another server or used for a schema backup.
What is the definitions file?
The definition file contains information and definitions of all objects in LavinMQ, like queues, exchanges, bindings, users, virtual hosts, permissions, and parameters.
Can the definitions file be exported and imported?
Yes, it can be exported to a JSON object, and imported as a JSON object.
Why do I need to export the definitions file?
An exported definitions file can be used to restore the basic setup on a secondary LavinMQ server. It might be used when creating a backup or moving from one AMQP-server to another.
How to export or import LavinMQ configuration
Definitions can be exported or imported as a JSON using any of the following methods:
- The LavinMQ management interface
- Using lavinmqctl commands export_definitions and import_defintions
- Calling the api/definitions API endpoint
Note: Be aware that the exported definitions contain hashed passwords.
Using the LavinMQ management
The LavinMQ management overview tab contains two sections, namely Upload definitions and Export definitions.
Upload definitions
Upload the definitions by clicking Choose file, then select the JSON file containing the definitions, and click upload.
Export definitions
Definitions can be exported for a specific virtual host or for the entire LavinMQ server. Select All or a specific vhost from the drop-down and click Download. When definitions are exported for just one virtual host, some information will be excluded from the exported file.
Using Lavinmqctl commands export_definitions and import_defintions
lavinmqctl allows for definitions to be exported in JSON format using the command lavinmqctl export_definitions.
Importing definitions is done using lavinmqctl import_definitions <file>
Calling the api/definitions API endpoint
More information on the definitions export and import functionality can be found in the LavinMQ API docs.
