Below are the test cases used to confirm container identification. These assume a user is running on Ubuntu 20.04 LTS or later. Essentially, each test case is to launch a container, copy the whatsthis binary over, and run it. Finally, confirm the container is correctly reported.
snap install docker docker run --detach --tty --name test ubuntu docker cp whatsthis test:/ docker exec -it test /whatsthis docker container rm --force test
snap install lxc lxc launch ubuntu-daily:focal test lxc file push whatsthis test/root/whatsthis lxc exec test /root/whatsthis lxc delete --force test
snap install podman podman run --detach --tty --name test ubuntu podman cp whatsthis test:/ podman exec -it test /whatsthis podman container rm --force test
Open a PowerShell console as Administrator and run the following to enable WSL and WSL 2:
dism.exe /online /enable-feature /featurename:Microsoft-Windows-Subsystem-Linux /all /norestart dism.exe /online /enable-feature /featurename:VirtualMachinePlatform /all /norestart
There is an additional kernel update package required for download here. Once installed, reboot the system to begin using WSL.
For more details see these official instructions here.
To set WSL 2 as the default version run the following as Administrator in a PowerShell console:
wsl --set-default-version 2
It can be helpful to switch between WSL 1 and WSL 2 during testing. Users can list all distributions and change the version of any running distribution by running.
wsl --list --all wsl --set-version <distro> [2|1]
Finally, to test the binary on a WSL distribution, copy it from your local
filesystem by accessing it from
cp /mnt/c/Users/<username>/Documents... whatthis ./whatsthis
