This appliance comes with RabbitMQ installed globally, following RabbitMQ official install guide, including the following features:

• Based on the latest RabbitMQ release (4.0.7-1) on Ubuntu 22.04 LTS
• Configuration file in /etc/rabbitmq/rabbitmq.conf
• TLS configuration with self generated certificates.

The contextualization parameters (CONTEXT section) in the VM template controls the configuration of the service, see the table below

Parameter	Default	Description
ONEAPP_RABBITMQ_NODE_PORT	5672	Port on which the RabbitMQ node will listen for connections
ONEAPP_RABBITMQ_LOOPBACK_USER	false	Allow the user to connect remotely
ONEAPP_RABBITMQ_USER	rabbitadmin	User for RabbitMQ service
ONEAPP_RABBITMQ_PASS	<random>	Password for RabbitMQ service
ONEAPP_RABBITMQ_LOG_LEVEL	info	Controls the granularity of logging {info,debug}
ONEAPP_RABBITMQ_TLS_ENABLED	NO	Enable TLS configuration
ONEAPP_RABBITMQ_PORT_TLS	5671	Port on which RabbitMQ listens for SSL connections
ONEAPP_RABBITMQ_TLS_CERT	````	Server certificate (base64 .pem)
ONEAPP_RABBITMQ_TLS_KEY	````	Server certficate key (base64 .key)
ONEAPP_RABBITMQ_TLS_PASS	````	Server certificate password
ONEAPP_RABBITMQ_TLS_CA	````	CA certificate chain

• Service credentials: By default, if not defined, the user generated for RabbitMQ will be "rabbitadmin" and its password will be automatically generated. You can find this information in /etc/one-appliance/config on the appliance.

When the parameter ONEAPP_RABBITMQ_TLS_ENABLED="YES" is set, the appliance will configure the RabbitMQ deployment to use TLS.

The appliance will create the folder /opt/rabbitmq/certs and three files in that location: server.pem with the contents of ONEAPP_RABBITMQ_TLS_CERT, server.key with the contents of ONEAPP_RABBITMQ_TLS_KEY and ca.pem with the contents of ONEAPP_RABBITMQ_TLS_CA. If either of those variables is empty, the scripts will autogenerate new certificates using the openssl tools.
