Using vscode remote on RPI

The Remote - SSH extension lets you use any remote machine with a SSH server as your development environment.

Login using SSH key

Create key

Create ssh key (private/public)

# ssh-keygen -t ed25519 -C "your_email@example.com"

ssh-keygen -t ed25519 -C "dev@dev.com"
# Type enter for empty passphrase

Tip

For simplicity (less secure) create key without passphrase

Copy key to remote

Copy the public key to remote machine

# ssh-copy-id user@remote
ssh-copy-id user@pi

ssh-agent

If the private key has passphrase we need to type it every time we start ssh session. ssh-agent keep the private key after we type the passphrase once
