How to copy files from local machine to docker container on windows

Question

I have to import data files from a user local file C:/users/saad/bdd to a docker container (cassandra), I didn't find how to proceed using docker commands. I'm working on windows 7.

Solution 1

Use docker cp.

docker cp c:\path\to\local\file container_name:/path/to/target/dir/

If you don't know what's the name of the container, you can find it using:

docker ps --format "{{.Names}}"

Solution 2

When using docker toolbox, there seems to be another issue related to absolute paths.

I am communicating with the containers using the "Docker Quickstart Teminal" which essentially is a MINGW64 environment.

If I try to copy a file with an absolute path to a container, I receive the error message.

$ docker cp /d/Temp/my-super-file.txt container-name:/tmp/
copying between containers is not supported

If I use a relative path, it simply works.

$ cd /d/
$ docker cp Temp/my-super-file.txt container-name:/tmp/

P.S.: I am posting this as an answer because of missing reputation for a comment.

Use this command will help to copy files from host machine to docker container.

docker cp c:\abc.doc <containerid> :C:\inetpub\wwwroot\abc.doc

Solution 4

It is not as straight-forward when using docker toolbox. Because docker toolbox has only access to C:\Users\ folder and there is a Oracle Virtual Box Manager in between, when you do get to copy the folder it is not directly copied to the container but instead to a mounted volume handle by Oracle VM machine. Like so:

/mnt/sda1/var/lib/docker/volumes/19b65e5d9f607607441818d3923e5133c9a96cc91206be1239059400fa317611/_data

How I got around this is just editing my DockerFile:

FROM cassandra:latest

ADD cassandra.yml /etc/cassandra/
ADD import.csv /var/lib/cassandra/
EXPOSE 9042

And building it.

If you are using docker-toolbox on windows, use the following syntax

docker cp /C/Users/Saad/bdd-restaurants cassandra:/var/lib/docker/containers
