How to change configuration parameters

This guide will help you to get familiar with ThingsBoard configuration files and parameters. We recommend to configure ThingsBoard using environment variables. This way you do not need to merge the configuration files when new platform release arrives. List of available configuration parameters and corresponding environment variables is located here.

How to change configuration parameters?

Monolithic deployment on Linux

If ThingsBoard is installed on Linux as a monolithic application, you may specify the environment variables in the thingsboard.conf file:

1
sudo nano /usr/share/thingsboard/conf/thingsboard.conf

Use simple example below to add new environment variable ‘HTTP_BIND_PORT’ with value ‘8081’.

1
2
...
export HTTP_BIND_PORT=8081

Monolithic deployment on Windows

If ThingsBoard is installed on Windows as a monolithic application, you may specify the environment variables in the thingsboard.yml file located in the following directory:

1
YOUR_INSTALL_DIR/conf

The configuration file is written in YAML.

All configuration parameters have corresponding environment variable name and default value. In order to change configuration parameter you can simply change it’s default value. For example:

1
2
server:
  address: "${HTTP_BIND_ADDRESS:0.0.0.0}"

In this case, ‘HTTP_BIND_ADDRESS’ is environment variable name and ‘0.0.0.0’ is a default value.

Docker based deployment

If ThingsBoard is installed in a docker compose environment, you may edit the scripts and add environment variables for the corresponding containers. See docker documentation for more details.

K8S based deployment

If ThingsBoard is installed in a K8S environment, you may edit the scripts and add environment variables for the corresponding deployments/stateful sets. See K8S documentation for more details.
