Dotnet-docker: I keep getting 1.0.0-preview* version on my latest & 1.1.0-sdk-msbuild docker installs

I installed microsoft/dotnet:latest and microsoft/dotnet:1.1.0-sdk-msbuild docker images.
When I run and log into both to issue > dotnet --version command, I always get the 1.0.0-preview* as versions

x-MacBook-Pro:x y$ docker images

How can I install the dotnet docker image where its dotnet version will be 1.1.0?

The Docker image version number is intended to align with the version of the runtime the image contains. The version number you are seeing when you do dotnet --version is the tooling (CLI) version, not the runtime version. The version of the tooling does not currently align with the runtime. This is something we are working on correcting. The 1.1.0-sdk-msbuild image, is the image you should be using to build projects that target the 1.1.0 runtime. You can see which runtime/shared framework is installed by looking in the /usr/share/dotnet/shared/Microsoft.NETCore.App folder. The 1.1.0-sdk-msbuild image actually contains two versions of the tooling 1.1.0 and 1.0.1. The 1.0.1 is there because it is required by the tooling. Again this is a point in time issue that we are working on resolving.
