Visual Studio Code remote development with Windows 10

Quick notes on getting set up with remote development in Visual Studio code on Windows 10.

Remote development over SSH

First make sure the following commands are executed from C:\System32\OpenSSH: ssh, ssh-keygen, scp. If they are located in e.g. Chocolatey’s bin folder, keys will be searched for in weird places. This can be verifed by installing which:

choco install which
which ssh

Create key pair in Windows 10 client

cd ~
mkdir .ssh
cd ssh
ssh-keygen -t rsa -b 4096

Prepare server

I am using a CentOS 7 server.

ssh user@server-hostname
mkdir -p ~/.ssh
touch ~/.ssh/authorized_keys
chmod 700 ~/.ssh
chmod 600 ~/.ssh/authorized_keys

Transfer public key from Windows 10 onto server

scp ~/.ssh/ user@server-hostname:~/.ssh/authorized_keys

Note: this will just copy the file onto the server, overwriting an already existing authorized_keys file if it exists.

Replace with your .pub file name, if you named it explicitly.

Test SSH keys

ssh user@server-hostname  # should not prompt for password

SSH config in Windows 10

If you haven’t already, install the “Remote development” extension in vscode.

Click the lower left >< icon in vscode and choose “Remote-SSH: Open configuration file…”. Then enter something like:

# Read more about SSH config files:
    HostName HOSTNAME

More options are outlined in the docs.

Connect to server over SSH and code away

Click the lower left >< icon in vscode and choose “Remote-SSH: Connect to Host…”. Choose your newly created profile.

A new vscode session will launch, and from the “Open folder” dialog, choose your project’s folder. Voila!
