VSCode¶

The instructions below should let users run their VSCode session on a compute node.

Pre-requisite installations:

• A recent version of vscode.
• Extension Remote - SSH from https://marketplace.visualstudio.com/items?itemName=ms-vscode-remote.remote-ssh.

Step 1. On your local machine, create ssh keys (existing ssh keys can also be used - no need to create new ones)

user@local:~$ ssh-keygen

Follow the prompts on the terminal to generate ssh-key pair, and note the directory where keys are being saved.

Step 2. Send the public key to Rāpoi

user@local:~$ ssh-copy-id -i ~/path/to/public/key RAAPOI_USERNAME@raapoi.vuw.ac.nz

The path ~/path/to/public/key should be the same as displayed when generating the ssh-key ~/.ssh/id_rsa.pub in some cases.

Step 3. Test the new keys

user@local:~$ ssh -i ~/path/to/public/key RAAPOI_USERNAME@raapoi.vuw.ac.nz

Step 4. On your local machine, update ssh config file

Create ~/.ssh/config file if it does not exist. Add hostname details to it:

Host VSCode_Compute
    User <YOUR_RAAPOI_USERNAME>
    HostName amd01n01
    ProxyJump raapoi_login

Host raapoi_login
    HostName raapoi.vuw.ac.nz
    User <YOUR_RAAPOI_USERNAME>

Host *
    ForwardAgent yes
    ForwardX11 yes
    ForwardX11Trusted yes
    IdentityFile ~/.ssh/id_rsa # Add your own private key path here
    AddKeysToAgent yes
    StrictHostKeyChecking no
    UserKnownHostsFile /dev/null

Step 5. On your local machine, open a terminal window and login to Rāpoi normally

user@local:~$ ssh raapoi_login

Once logged in alloc resources for the VSCode session

RAAPOI_USERNAME@raapoi-login:~$ srun -t0-01:00:00 -wamd01n01 --mem=4G --pty bash

Step 6. Connect VSCode session

Open VSCode window, and click on the bottom left corner that says Open a Remote Window, and then choose Connect to Host and then selecting VSCode_Compute as a host.

Once a connection is established, your VSCode session should be running on a compute node now.

{
    "files.watcherExclude": {
        "**":true,
    },
    "files.exclude": {
        "**/.*": true,
    },
    "search.followSymlinks":false,
    "search.exclude": {
        "**":true,
    },
    "terminal.integrated.inheritEnv": false,
}

Step 7. To close VSCode session.

Go to File > Close Remote Connection
