This past week, I’ve spent time wiping away my ignorance of containers. To do this, I started in my usual way:
- Buy a bunch of books. Probably too many.
- Work through books, doing exercises as I go.
The first book I’m running through is Using Docker: Developing and Deploying Software with Containers by Adrian Mouat. I’m posting this bit now to hopefully help others.
When working through the exercise to backup the redis database in Chapter 3, I ran the command to backup the database:
docker run --rm --volumes-from myredis -v $PWD/backup:/backup debian cp /data/dump.rdb /backup/
This then emits the error message:
C:\Program Files\Docker\Docker\Resources\bin\docker.exe: Error response from daemon: Drive has not been shared. See 'C:\Program Files\Docker\Docker\Resources\bin\docker.exe run --help'.
This is happening because I never shared the C-Drive with Docker. To do this, right click on the Docker icon sitting in your toolbar and select Settings… . Then, select Shared Drives and check the drive(s) on your system which you want to be able to use.
Upon clicking Apply, enter your credentials. The command should now work.
One other note: I found that the command did not work right in cmd.exe or some bash shells. It did work just fine from a powershell window. So, that’s another note…

Posting this here mostly for me so I can find this easily again:
I’m monitoring this URL, waiting for .NET 4.7 support to appear. I’m hopeful that we’ll see something early in 2017 Q4, but I won’t be holding my breath either 😉

TLDR; Azure OS Family 5 requires Remote Desktop passwords >= 10 characters. Anything less will cause your login to fail, repeatedly requesting that you re-enter your password.
I ran into an issue when upgrading an Azure application from OS Family 4 to OS Family 5. We have configured RDP for our development deployments. As part of that deployment, we had configured special passwords for each environment. Those passwords had a strong enough length when we added them a few years ago: 8 and 9 characters. OS Family 5 (Windows Server 2016) requires that the passwords are at least 10 characters long.
As a result, we found that the deployment went fine (no errors reported) but that we simply couldn’t log in post upgrade. Looking on the portal, we noted that one has to have a password of at least 10 characters to add Remote Desktop from the portal. We counted the characters in our passwords, adjusted lengths, and found we could login again.
