-## With MSI
+MongoDB in a Windows NanoServer Docker image
 
-The [3.2/msi/Dockerfile](3.2/msi/Dockerfile) downloads the MSI file of MongoDB and installs it with msiexec.
-The reason for this is that the MSI file also contains `*.pdb` files, but also
-the MSI file itself will be cached and Windows also writes internal binary files.
+There also is a `Dockerfile` for the MongoDB Enterprise editition. You have to build it locally.
 
-This results in a big Docker image of about **805 MByte**.
-
-## With ZIP
-
-The next step is to download the ZIP file instead of the MSI and extract it and remove the Zip file in a single `RUN` command. The [3.2/Dockerfile.build](3.2/Dockerfile.build) does this.
-The additional optimization is to remove the `*.pdb` debug files from the container as well.
-
-The size of this Container is **249 MByte**.
-
-## With COPY
-
-Using two steps to build the final Docker image can reduce the size.
-Copying the extracted files from the ZIP container with a mounted volume and then
-using the [3.2/Dockerfile](3.2/Dockerfile) copying the directory back into a new Docker image results in an even smaller image.
-
-The size of this Container is **171 MByte**.
