\nIf you want to play with OpenShift on your laptop, you can, in a Virtual Machine. I have VirtualBox installed on my laptop. I’ll install Minishift here, which will create the VM to run OpenShift with few simple commands only. On Linux you can refer to Daniel’s post<\/a>. Here is the Windows version. Oh, and Daniel did that to run Postgres but my goal is to run an Oracle container of course. Or MySQL maybe.
\n
\nI’ve downloaded minishift-1.18.0-windows-amd64.zip<\/a> and unzipped it in D:\\Downloads\\minishift-1.18.0-windows-amd64 where I have minishift.exe<\/p>\n
Minishift<\/h3>\n
I configure to use VirtualBox<\/p>\n
\nminishift config set vm-driver virtualbox\n<\/code><\/pre>\nIt is installed in my Windows profile:<\/p>\n
\nC:\\Users\\fpa\\.minishift\n<\/code><\/pre>\nBe careful, minishift do not know that we have multiple drives in Windows. When I was running minishift.exe from the D: disk is was not able to find the virtual machine’s files that were on C:<\/p>\n

So, that’s an easy way to run Oracle on Docker when you have VirtualBox. One download and 5 commands and I’m ready to connect. But that’s not the goal. Here we have OpenShift here to manage multiple Docker containers.<\/p>\n
According to the ‘minishift start’ output I have a Web server on https:\/\/192.168.99.102:8443 (user: system, password: admin)<\/p>\n
It already contains a lot of databases:
