Unrecognised volume spec running preview docker image on Windows

Frequently Asked Questions Installation
#1

Hi,

I just tried installing the Docker image on the latest version of Docker for Windows according to the instructions and it failed with the error message Error response from daemon: Unrecognised volume spec: invalid volume specification: './mattermost-data'.

See command line output below:

>docker run --name mattermost-preview -d --publish 8065:8065 --add-host dockerhost:127.0.0.1 mattermost/mattermost-preview

Hey @pichouk, this seems to be an issue on Docker, or let me know if it’s not specifically docker related and I’ll post this for our devs to look at.

#3

@amy.blais It seems to be Docker related, but it’s related to the mattermost/mattermost-preview Docker image, not the Production ready image (mattermost/mattermost-docker) I maintained.

My guess is that ./mattermost-data is not a valid path on Windows and it is the default volume path in the mattermost-preview image. But @sparkplug seems to follow the documentation and the documentation says that it should works on Windows.
We need help from someone that know the mattermost-preview image, if possible someone that used it on Windows.

#4

@cpanato Are you more familiar with docker-preview image to look at this, or do you know someone on our team who is most familiar with it?

#5

I have just tried this again and still get the same error. As far as I can see, this is the only way to install the Mattermost server on Windows?
