Can't get CDAP Sandbox (docker) 6.9.2 working

[Neil Kolban]

My goal is to get CDAP Sandbox v6.9.2 running in a Google Cloud Debian Linux Compute Engine.  Essentially, this is a Linux environment.

I am following the instructions documented here.  I am running the command:

docker run -it -p 11015:11015 -p 11011:11011 --name cdap-sandbox caskdata/cdap-sandbox:6.9.2 cdap sandbox start --enable-debug --foreground

and what is returned is:

docker run -it -p 11015:11015 -p 11011:11011 --name cdap-sandbox caskdata/cdap-sandbox:6.9.2 cdap sandbox start --enable-debug --foreground
[INFO] Docker detected: running in the foreground with output to STDOUT
Fri Jan 12 23:21:21 UTC 2024 Starting CDAP Sandbox ...Listening for transport dt_socket at address: 5005
LOGBACK: No context given for io.cdap.cdap.logging.framework.local.LocalLogAppender[io.cdap.cdap.logging.framework.local.LocalLogAppender]
CDAP Sandbox started successfully.
Connect to the CDAP UI at http://localhost:11011

However, when I try and connect the browser, I get no response.  I get a "This site can't be reached" error.  I then tried a curl command and got:

$ curl localhost:11011
curl: (56) Recv failure: Connection reset by peer

Sadly, I am now stuck.  Are these any diagnostic procedures or recipes I might follow?
