Allows you to use ssh keys through ssh-agent on Windows in WSL2 machine. Works with Keepass KeeAgent plugin or open-ssh-agent. This approach uses npiperelay.exe to forward Windows named pipe into WSL2.

• WSL2. You can check version with wsl --list --verbose
• socat installed in your WSL.

sudo apt install socat

• Dowload repository as zip
• Extract files
• Run install.sh in WSL2

sudo install.sh

• download npiperelay and extract npiperelay.exe to /usr/local/bin/npiperelay.exe
• copy wsl-ssh-agent-forwarder to /usr/local/bin/wsl-ssh-agent-forwarder
• set execution permissions to wsl-ssh-agent-forwarder and npiperelay.exe
• add line . /usr/local/bin/wsl-ssh-agent-forwarder to ~/.bashrc

It is possible to use systemd service on WSL2 0.67+ instead. Update your wsl by command wsl --update --web-download Check what systemd enabled in /etc/wsl.conf

[boot]
systemd=true

Copy wsl-ssh-agent-relay.service to /etc/systemd/system folder.

systemctl daemon-reload
systemctl start wsl-ssh-agent-relay.service
systemctl enable wsl-ssh-agent-relay.service

Add export SSH_AUTH_SOCK=/var/run/wsl-ssh-agent.sock into ~/.bashrc

Wrapper allows using docker command directly from windows converting Windows paths to paths inside WSL.

Uninstall docker-cli if it's installed.

Copy docker.bat into any location added to PATH. C:\bin for example

Copy wsl-docker-wrapper into /usr/local/bin inside WSL

Set execute permission chmod +x /usr/local/bin/wsl-docker-wrapper

Now you will be able to use docker commands from Windows and don't care about paths while mounting volumes.
