Hello, I was setting up Docker for windows and I had the shown errors

You need to run "Docker Desktop" first.

I've already opened it, does running it mean something else?

Now re-run the same command

Same problem

I would recommend using the windows subsystem for Linux, rather than run directly from Windows. In which case you will also need to enable WSL in docker

Btw. you are using the commands for Linux (export for example only exists in Bash, what you are looking for is SET). Also, I'd like to recommend our enhanced Docker-Container: https://github.com/hpretl/iic-osic-tools In this repo, start scripts are included, also for Windows! And for your Docker issue and as already suggested: https://docs.microsoft.com/en-us/windows/wsl/install Install and enable WSL2 (note, there is a big difference between WSL2 and WSL1), then Docker should work fine!

On Windows, I do recommend the HyperV backend rather than WSL2.

Really, why? Docker itself recommends WSL2 because of it's performance and general convenience.

There are certain features which are only available when HyperV is used. E.g. limiting the memory (RAM) allocation.

You mean on a per-Container basis or for the whole "Docker-VM" in general? Because you can also limit the WSL memory allocation in a config file.

I mean per-container. I know that Microsoft is improving WSL2 so they can replace Docker Desktop, but the solution is not there yet.
