Auto generated evar does not match with actual value

[robobakery]

hey, nanobox guys. how are you?

i am suffering an unknown issue with environment variable generation
when using an image selenium/standalone-chrome as data.chrome

issue: DATA_CHROME_HOST has wrong ip address.

this issue only happens when i deploy to production server.

here i attach my case to be reproduced,
please check and see if this is happening inside nanobox or not.

...

$ nanobox run
$ curl -H "Content-Type: application/json" --data @body.json http://172.21.0.4:4444/wd/hub/session

{"status":0,"sessionId":"81f94fc056c4b8d1f14fd152565134ea","value":{"applicationCacheEnabled":false,"rotatable":false,"mobileEmulationEnabled":false,"networkConnectionEnabled":false,"chrome":{"chromedriverVersion":"2.38.552522 (437e6fbedfa8762dec75e2c5b3ddb86763dc9dcb)","userDataDir":"/tmp/.org.chromium.Chromium.0f1Lwu"},"takesHeapSnapshot":true,"pageLoadStrategy":"normal","databaseEnabled":false,"handlesAlerts":true,"hasTouchScreen":false,"version":"66.0.3359.117","platform":"Linux","browserConnectionEnabled":false,"nativeEvents":true,"acceptSslCerts":false,"acceptInsecureCerts":false,"locationContextEnabled":true,"webStorageEnabled":true,"browserName":"chrome","takesScreenshot":true,"javascriptEnabled":true,"cssSelectorsEnabled":true,"setWindowRect":true,"unexpectedAlertBehaviour":"","webdriver.remote.sessionid":"81f94fc056c4b8d1f14fd152565134ea"}}

DEPLOYMENT

$ nanobox remote add nanobox-wrong-evar
$ nanobox deploy
$ nanobox console do.1

$ docker inspect data.chrome.1.1
IPv4Address = 192.168.0.14
$ curl -H "Content-Type: application/json" --data @body.json http://192.168.0.14:4444/wd/hub/session

works fine

however, in config tab, what i see is DATA_CHROME_HOST = 192.168.0.13

what is actually happening with evar auto generation?
