To Do

1. Generate the New SSH Key (whithout passphrase) 

ssh-keygen -t ed25519 -f ~/.ssh/id_rsa_deploy -N ""
Enter fullscreen mode Exit fullscreen mode

2. Copy the Public Key to the Server 

ssh-copy-id -i ~/.ssh/id_rsa_deploy.pub server-user@server-ip
Enter fullscreen mode Exit fullscreen mode
  1. Configure the SSH Client 
Host deploy-server
    HostName server-ip
    User server-user
    IdentityFile ~/.ssh/id_rsa_deploy
    IdentitiesOnly yes
Enter fullscreen mode Exit fullscreen mode
  1. Test the Connection 
ssh deploy-server

(Important): Fix permissions (if SSH refuses key)

Run these on your deployment machine:

chmod 600 ~/.ssh/config
