I installed sandbox hdp on ubuntu 18.04 using docker. When I do docker ps I see sandbox-hdp and sandbox-proxy running. But am not able access ambari dashboard on port 8080. I see below error in docker error logs - 

2020/07/05 11:18:25 [error] 6#6: *87 connect() failed (111: Connection refused) while connecting to upstream, client: 172.29.199.221, server: sandbox-hdp.hortonworks.com, request: "GET / HTTP/1.1", upstream: "http://172.18.0.2:8080/", host: "localhost:8000".

 

However, I was able to access cloudera welcome page through 1080.
