Can't use environment variables set at build time during run/exec (Windows containers Server TP5)

[ad22]

After setting environment variables using ENV directive in docker build, I cant seem to access them in the docker run/exec commands. See docker inspect and docker exec outputs below. Is this intended behavior?

@ad22 Just curious did you install TP5 in VM? I tried install it on macbook natively, but it didn't found drivers for hdd controller :(

[ad22]

@KostyaSha yes, I've installed it on a VM

Also, it seems like this issue belongs more to the docker project than the plugin itself, so I'm closing this. Sorry!

[KostyaSha]

@ad22 what VM? virtualbox?

[ad22]

@KostyaSha ESXi..

[KostyaSha]

With enabled nested virtualisation?

[ad22]

Im using windows containers, not the hyper-v based docker engine - I could not get that to work with nested virtualization on a VM, only on a bare metal machine.
