Docker in Azure
I’m playing with Docker and have it set up locally in Hyper-V for testing. I really want to have a public/internet facing host though. I remembered I had some free Azure credits from my MSDN Subscription so that’s where I’m getting started.
Things I have:
First, use Docker Machine to establish your Docker VM in Azure. Of important note are the -d (driver) argument and the Subscriber ID. You find that in your “Settings” in the Azure portal.
PS C:\Users\bg> docker-machine.exe create -d azure --azure-subscription-id o.b.f.u.s.c.a.t.e.d public Running pre-create checks... (public) Microsoft Azure: To sign in, use a web browser to open the page https://aka.ms/devicelogin. Enter the code FJP4 VWRS3 to authenticate. (public) Completed machine pre-create checks.
