This guide will help you become familiar with TBMQ configuration files and parameters. We strongly recommend configuring TBMQ using environment variables. This way, you won’t need to merge the configuration files when a new platform release arrives.
The list of available configuration parameters and corresponding environment variables can be found here.
How to change configuration parameters?
Docker-Based deployment
If TBMQ is installed in a Docker Compose environment, you can edit the scripts and add environment variables for the corresponding containers. For more details, refer to the Docker documentation.
K8S-Based deployment
If TBMQ is installed in a K8S environment, you can edit the scripts and add environment variables for the corresponding deployments/stateful sets. For more details, refer to the K8S documentation.
Configuration parameters
The configuration file is written in YAML format. All configuration parameters have corresponding environment variable names and default values. To change a configuration parameter, simply modify its default value. For example:
1
2
server:
address: "${HTTP_BIND_ADDRESS:0.0.0.0}"
In this case, ‘HTTP_BIND_ADDRESS’ is the environment variable name and ‘0.0.0.0’ is the default value.
You can use the simple example below to add a new environment variable ‘HTTP_BIND_PORT’ with value ‘8084’.
1
2
...
export HTTP_BIND_PORT=8084
The parameters are grouped by system components. The list contains the name (address in thingsboard-mqtt-broker.yml file), environment variable, default value, and description.
