@MichaelSimons Yes, that helped. I upgraded to kernel 4.2.8 (http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.2.8-wily/), restarted the host, started a container and now the dotnet CLI works. Thank you for your help!

For RTM, I think it would be great to have a Docker on Ubuntu image in Azure that supports running dotnet CLI without prior updating the kernel. However, my current problem is solved. Thank you again.

Just a hint for people who want to demo dotnet CLI on Azure in a Docker container: You can use the Azure ARM Quickstart Template for Docker on Ubuntu (https://github.com/Azure/azure-quickstart-templates/tree/master/docker-simple-on-ubuntu). This will give you an environment where dotnet CLI works inside a Docker container out of the box. No need to update the Linux kernel there.
