Mounting folders to a Windows Docker container from a Windows host
Mounting a folder to a Docker container allows you to share data back and forth on your host system. It’s a great feature to have especially on Windows where command line editors are not as native to the OS as they are with Unix/Linux.
Your mileage may vary with the information cited in this article depending on the version of Docker you are using. My setup at the time of this writing is…
- Docker Desktop v3.0.4 (51218)
- Engine v20.10.2
Mounting Windows file paths
There are numerous articles available on how to mount folders inside of Docker images.
- Unable to share a local windows path with a container in Docker
- How To Mount Your Current Working Directory To Your Docker Container In Windows
And mounting in general…
Though many articles cite different methods for referencing paths.
Referencing Windows paths
It’s likely that the way to reference Windows paths has changed over time and for different versions of Docker. I’m not entirely certain and have not researched it in depth but here is a capture of the different folder path formats I’ve encountered
//c/myFolder /c/myFolder c:\myFolder
Of all the pathing styles the last one is the format that worked for me…
docker run -it --name myDockerContainer1 --mount src=C:\myFolder,dst=c:\myDockerMount,type=bind aDockerImage:latest
If a path has spaces you can use quotes to contain it…
docker run -it --name myDockerContainer1 --mount src="C:\myFolder\sub folder",dst=c:\myDockerMount,type=bind aDockerImage:latest
- An absolute path must be used when specifying folders
- Use quotes around a path if it contains spaces
