Helix TeamHub configuration

The Helix DAM configuration settings are in the /var/opt/hth/shared/hth.json configuration file. It includes settings manipulated through TeamHub Admin UI. This configuration file is also part of Helix DAM Backups, if enabled.

Every time Helix DAM is reconfigured, the configuration file is read and the configuration is applied to all of Helix DAM services. Some of the configuration flags dictate what mode of deployment Helix DAM is running, where others simply override default Helix DAM settings.

Format

The configuration file is formatted as JSON. It is important to keep the correct format of the file, otherwise the Helix DAM reconfiguration will not work. JSONLint is a trusted open-source JSON linter option to help verify the syntax of the JSON contents.

Note

Remember that duplicate keys override the previously defined keys.

To see the current configuration applied to the server, run the following command:

sudo hth-ctl show-config

Overriding defaults

Helix DAM comes with many sensible defaults for both service and application behavior. If the default configuration needs to be adjusted, use the dictionary provided below as a reference.

Each configuration flag has a section, for example app, nginx, etc. These sections separate settings into logical categories. To use the dictionary, simply merge the section to the existing configuration file at /var/opt/hth/shared/hth.json with a required key and value.

Whenever changing any of the configurations, pay attention to the type of the key and where available refer to the linked documentation. Also, remember that configuration is not applied until the sudo hth-ctl reconfigure command has been run.
