No it's not resolved, now I'm trying to think of a way to troubleshoot Chrome not being able to directly download without prompting the window.
My best bet is Chrome is doing some filesystem call that doesn't work well with NFSv4 to determine the destination is writable or not. Hi ybizeul , is there something we could do to help?
I mean, my first impression is that this is not a docker-selenium issue but more one related to the environment where the containers are running. Just let us know. Hi diemol , I think the problem is more on the selenium docker side, if you consider that's something that should be working. The fact that Chrome works fine on a local mount and not on a NFS docker-volume mount is disturbing and will be hard to troubleshoot without getting the Chrome people involved.
I tried looking at the source code without much success, and not many people are actually running browsers in container that would have the experience to troubleshoot.
NFS mounts in docker are quite standard and becoming mainstream, it's something that selenium users expect to be able to rely on especially for web test downloads and uploads and at this point that's not functional. I don't think so, but I couldn't setup a firefox container that doesn't prompt, even when not using mounts. Chrome seems to change the options for doing a direct download with nearly every release, so this is going to be highly dependent on the version of Chrome in use.
If you just need to download something, rather than fiddling with Chrome options Hi ybizeul. What are the next steps here? Could you provide detailed instructions on how to reproduce this issue? So we can help to get it solved? Right now we have only a set of assumptions. I think I have, running the provided code on NFS persistent volume breaks the download.
I think lots of people need persistent volumes for these tests, nevertheless I think it's an expectation that persistant volume shouldn't interfere with features. So there is the script up there, and the download location has to be a docker volume from a nfs server, I use rancher but it could be any orchestrator probably.
Additional question, have you tried to write a file into the container when the volume is mounted? Do you get an error? Yes, if I go in the container and create a new file as the selenium user it works fine. Actually, if use the debug container and answer the save panel from VNC, the file saves and the execution continues.
I'm getting the same kind of issue on a server not sure it's the same matter. Jun 30, If you have docker volumes attached to a container we can just use cp command to copy files from docker containers. See if your container have volumes attached, we can use below. Step1: Get container ID from ps from where you want to get file. This id is useful for inspecting the docker container properties. May 07, filename: Filename to transfer.
First, let's test the authentication from the localhost. The following command should return the hostname of the docker container. With the above working the next command will.
Nov 30, It turned out that the Moby Project has a shell script on the Moby Github which can download images from Docker Hub in a format that can be imported into Docker: download-frozen-image-v2.
In this article, we will show you how to use docker cp to copy files or folders from a docker container to the host local file system or the reversed.
For example, here is a running container, id is dda5fc , later we will copy files from and to this container. S The docker cp command works similar to the SSH scp command.

Often when debugging applications, it is useful to copy files into or out of our Docker containers. In this tutorial, we'll look at some different ways we can copy files to and from Docker containers.
