BC21: SetupWebclient breaks containers when run\my is a shared volume

[michvllni]

We use several containers that run on the same volume.
Our volume points to C:\run\my inside the container.

SetupWebClient appears to replace the management module everytime a container is created:

nav-docker/generic/Run/210-new/SetupWebClient.ps1

Line 47 in 614783b

Set-Content -Path $NAVWebClientManagementModule -Value $WebManagementModuleSource -Encoding UTF8

The issue is when launching multiple containers at once this breaks the container creation as the containers simultanously try to update the file:

Is there any other way to fix this rather than using a separate volume for each container?

I think it is a bad idea to share c:\run\my as this is used for files related to this container.
You should share another volume with your files for the containers.

I somehow had to attach my scripts to the default scripts, and according to documentation I should put them into C:\run\my.

This is the reason why I was doing this
