This is a step by step guide to setting up Visual Studio Code - Remote SSH. This helps to connect to Linux system remotely and add, edit, delete files and folder with Visual Studio code, at the same time I can execute script files. This helps to manage Linux and use it as all in one tool for DevOps activities. As VS Code is open source tool and SSH extension is free (Author Microsoft), I don't have to pay for any other commercial tools.
To start configuration, I am on my windows system. and created a ssh key using command ssh-keygen -t ed25519. This creates public and private keys inside current user profile folder inside .ssh folder. We will need .pub extension key contents which I will copy and paste on Linux server.
To view the content of file use command - cat C:\Users\UserProfile\.ssh\id_ed25519.pub.
Next go to remote Linux server use the key and add it to ~/.ssh/authorized_keys file. You can use below command to add information.
echo 'Your SSH key username@computername' >> ~/.ssh/authorized_keys
Once key is added on Linux, I am back on windows system. I have Visual Studio code is already installed. Go to Extension view, Search for ssh in the Marketplace. Install Remote - SSH and related extensions from the list and Microsoft is the author developer for these extensions.
Next you will see the remote connection icon appeared on the left hand side, once the Remote SSH extension is installed. On the SSH click settings icon to Open SSH config file (C:\User\UserProfile\.ssh\config), Add below information in the config file.
Host Ubuntu001 HostName 192.168.34.90 User vjanvi IdentityFile C:\Users\UserProfile\.ssh\id_ed25519
Configuration is completed, You will see Linux server is added to the SSH section, Click connect in new windows.
This is the last screenshot that shows I am connected to Linux server over VS Code Terminal from windows. In the left pane I have opened a remote Linux folder and can Add Edit or delete files on the go.
