2.4 JSON Configuration File
EVO:RAIL relies on a JSON-formatted file to initially populate fields in the user interface. The
end user is presented with this data during initial appliance configuration (both for Customize
and Just Go workflows). The initial configuration file is found on the EVO:RAIL service
datastore at:
/usr/lib/vmware-marvin/marvind/webapps/ROOT/WEB-INF/classes/
default-config-static.json
Before configuring EVO:RAIL, customers must read the VMware EVO:RAIL Network User
Guide and fill out the
EVO:RAIL Network Configuration Table
. Sample JSON configuration
files that correspond to the default values listed in this table are found in VMware KB articles
for each EVO:RAIL release.
Your Qualified EVO:RAIL Partner (QEP) may provide an optional service to pre-populate a
custom configuration file with values from the
EVO:RAIL Network Configuration Table
,
defined by the customer at the time of system order. The QEP would replace the data in the
default configuration file and the customer could use either Customize or Just Go.
A similarly formatted JSON file could be used with
Upload Configuration File
, which is
available after you select
Customize
. This feature allows you to use a modified configuration
file onsite, after shipment from your QEP. The primary use case for this feature is a ROBO
environment, where EVO:RAIL appliances are distributed with a similar configuration file for
multiple locations.
Important Notes:
•
The JSON file format may change throughout EVO:RAIL releases. Please get the sample
JSON file that corresponds to the software release that your appliance was built with at
the QEP factory; then edit the sample file for your configuration.
•
EVO:RAIL expects the data in the configuration file in a specific format. Any changes to
the JSON format will result in unexpected results and/or crashes.
•
There is no built-in capability to generate and export an updated copy of an EVO:RAIL
JSON configuration file from the user interface.
Upload Configuration File
Pre-populate a custom configuration file for use in the Customize workflow with the following
steps:
Step 1. Obtain a copy of the
default-config-static.json
file for the EVO:RAIL release
that you will be configuring from VMware Knowledge Base: 2106961
Step 2. Edit your new configuration file to insert the values from the
EVO:RAIL Network
Configuration Table
.
Step 3. Make sure that the filename has a “
.json
” extension.
