Configure

The vantage6-node requires a configuration file to run. This is a yaml file with a specific format.  To create an initial configuration file, start the configuration wizard via: vnode new . You can also create and/or edit this file manually.
The directory where the configuration file is stored depends on your operating system (OS). It is possible to store the configuration file at system or at user level. By default, node configuration files are stored at user level. The default directories per OS are as follows:
Operating System
System-folder
User-folder
Windows
C:\ProgramData\vantage\node
C:\Users\<user>\AppData\Local\vantage\node
MacOS
/Library/Application Support/vantage6/node
/Users/<user>/Library/Application Support/vantage6/node
Linux
/etc/vantage6/node
/home/<user>/.config/vantage6/node
The command vnode looks in certain directories by default. It is possible to use any directory and specify the location with the --config flag. However, note that using a different directory requires you to specify the --config flag every time!
Configuration file structure
Each node instance (configuration) can have multiple environments. You can specify these under the key environments which allows four types: dev , test,acc and prod . If you do not want to specify any environment, you should only specify the key application (not within environments) .
We use DTAP for key environments. In short:
dev Development environment. It is ok to break things here
test Testing environment. Here, you can verify that everything works as expected. This environment should resemble the target environment where the final solution will be deployed as much as possible.
acc Acceptance environment. If the tests were successful, you can try this environment, where the final user will test his/her analysis to verify if everything meets his/her expectations.
prod Production environment. The version of the proposed solution where the final analyses are executed.

Configure using the Wizard
The most straightforward way of creating a new server configuration is using the command vnode new which allows you to configure the most basic settings.
By default, the configuration is stored at user level, which makes this configuration available only for your user. In case you want to use a system directory you can add the --system flag when invoking the vnode new command.
Update configuration
To update a configuration you need to modify the created yaml file. To see where this file is located, you can use the command vnode files . Do not forget to specify the flag --system in case of a system-wide configuration or the --user flag in case of a user-level configuration.
Local test setup
Refer to here if you want to run both the node and server on the same machine.
