@Rafael Coss, yes I turned off the pop-up blocker. I thought that was it too. @Jay SenSharma, I pretty much just copy and pasted the docker run command and I believe it exposed port 8080 @glupu, yes I am running the docker sandbox from my mac which is using docker for mac. I pretty much just followed the instructions from the link I posted above. I ran the 'docker run ...' command and then did a ssh -p 2222 root@localhost. I changed my password from 'hadoop' to my own and then ran /etc/init.d/startup_script start but after going to localhost:8888 the dashboard wouldn't launch. So yesterday I ran 'service ambari-server status' and it said it wasn't running but gave a message about a 'Stale PID File at: /var/run/ambari-server/ambari-server.pid'. So I ran 'service ambari-server start' and again 'service ambari-server status' showed the same thing even tough the 'ambar-server start' command said it completed successfully. Finally I ran 'service ambari-server restart' and then it was running and I can get to the dashboard. Why was that? And am I supposed to run the docker image of the sandbox this way? I noticed @jay had something which said 'Hortonworks Docker Sandbox' listed in his VirtualBox. I thought having a docker image was so that you didn't need a VM. So now I'm a bit confused on how I should be using the docker image of the sandbox. . . thanks, I appreciate the help!
