Error copying file to container using Podman on Windows 11

I'm trying to run a SQL script against a SQL Server instance that is running inside a Podman container on a Windows 11 host.

To do this, I'm attempting to copy the script file to the container using the following command:

podman cp .\baseline.sql mssql-server-1:/tmp/baseline.sql

it returns:

error rewriting "c:....\baseline.sql" to be relative to "/": expected root directory to be an absolute path, got "/"

It seams the paths are ok, because if I change either the source or destination Podman reports correctly the error.

Has anyone encountered a similar issue or can provide insight into what might be going wrong here? Any advice or suggestions would be greatly appreciated.

Solution

  • This is generally followed by containers/podman issue 14862:

    In the meantime as a workaround you can access your windows drive through the mount that is on the wsl linux host, using unix path conventions, like this:

    podman cp /mnt/c/users/foo/bar/file.bak mycontainer:/var/opt/backups

    And:

    I was able to get a file copy into my container working with the following.
    I redeployed my podman machine, rebuilt my container...
    this does work:

    wsl -d podman-machine-default -u user enterns podman cp \
    /mnt/d/2022_Projects/assessments/HK197500195.bin se92:/root/

    Or:

    wsl -d podman-machine-default -u user enterns podman cp \
    /mnt/c/"your file location" container:/sql/

    Meaning:

    "Prefixing" docker cp with wsl -d podman-machine-default -u user enterns also worked for me. Concretely, I wrote:

    wsl -d podman-machine-default -u user enterns podman cp \
    "myfile.txt" my-container-name:/tmp/

    Also:

    Simple workaround for me is to use podman machine ssh command like this:

    podman machine ssh "podman cp /mnt/c/dev/file.py container:/usr/src/app"
