Configuration properties that can be defined via the CLI, system properties, environment variables, or file.

|
|
|
This project provides configuration properties, such that ANYTHING in the config file can ALSO be passed in on the command line or as an env/system property
|
|
|
|
```
|
|
commandline > system property > environment variable > properties file
|
|
```
|
|
Once a property has been defined, it cannot be overloaded again via a different method, as specified in the above hierarchy,
|
|
|
|
During a save operation, overloaded values will be ignored unless they were manually changed to something different
|
|
|
|
|
|
Additionally, it is possible to set an environment variable names that might conflict with the standard set of names, for example,
|
|
```
|
|
PATH
|
|
```
|
|
* The system uses PATH, but if we want to use path for something different, we can via setting the prefix.
|
|
* For example, setting the prefix to `CONFIG__` means that for us to set the `path` property, we set it via
|
|
|
|
```
|
|
CONFIG__path="/home/blah/whatever"
|
|
```
|
|
* And this way, **OUR** path does not conflict with the system path.
