server.json Env Var overrides

Every server setting can be overridden by convention by creating environment variables in the shell where you run box. This is idea for CI builds were you want to easily set ports, or tweak settings for your build. You set set these as actual environment variables or Java system properties of the CLI.

The var must start with the text box_server_ and will be followed by the name of the setting.

box_server_profile=production

For nested settings inside of a struct or array you can use underscores to represent dots.

box_server_web_http_port=8080

The overrides are applied using the same mechanism that the config set command uses, which means you can also pass JSON directly for complex values.

# JSON which will be parsed
box_server_web_ssl={ "enabled" : true, "port": 443 }

On OS's like Windows which allow for any manner of special characters, you can provide any string which would also be valid for the config set command. Ex:

# dot-delimited keys
box_server_web.http.port=8080
# array indexes too
box_server_web_rules[1]=path-suffix(/box.json) -> set-error(404)
box_server_web_rules[2]=disallowed-methods(trace)

When you provide JSON, the append flag will be set to true when adding the configuration to what's already in CommandBox.

Overridden env vars will not be written to the server.json file and will be lost when box stops. They will also take precedence and override any explicit server.json settings already set but will NOT override actual parameters to the server start command.
