Configuration loading is designed for containerization in mind. The container engine and orchestrator can mount volumes (secret or regular) as well as set the environment variables as outlined below.
You may set configurations through both files and environment variables. Please note that environment variables will
override the settings in the configuration files. The configuration files are all expected to be in YAML format.
The configuration loader will search for the configurations in the following order:
| Location | Details |
|---|---|
/etc/FTeX.conf/ |
The etc directory is the canonical location for configurations. |
$HOME/.FTeX/ |
Configurations can be located in the user's home directory. |
./configs/ |
The config folder in the root directory where the application is located. |
| Environment variables | Finally, the configurations will be loaded from environment variables and override configuration files |
The expected file name is HTTPGraphQLConfig.yaml. All the configuration items below are required.
