Our Xamarin base image

1. update dockerfile

2. build local version:

   docker build -t inforitnl/imagename .
   

3. push new version to dockerhub:

   docker push inforitnl/imagename:latest
   

4. tag and push again (optional but recommended):

   docker tag inforitnl/imagename inforitnl/imagename:1
   docker push inforitnl/imagename:1
