Read Time: 2 Minutes Hero Light We’re excited to roll out a new feature that makes accessing your GPU containers easier and more secure than ever before. Starting today, GPU Trader supports zero-trust SSH tunnel access. That means no open ports, no network exposure, and no extra setup headaches. Just a secure, encrypted tunnel into your container on demand.

​
What’s New?

With a few clicks and a one-line command, you can now:
  1. Launch a secure Docker-based tunnel from your local machine
  2. Authenticate with your own SSH keypair
  3. Connect directly to your running container just like native SSH
  4. Shut down access automatically when the session ends
It’s shell access the right way: ephemeral, authenticated, encrypted. GPU Trader runs on a zero-trust model. In practice, this means:
  • 🔐 No permanent ports open on your host or container
  • 🔒 Access is tied to your user and SSH key
  • 🚪 Sessions only live while you’re connected
  • 🚫 No blanket access—just what’s needed, when needed
Whether you’re running training loops, monitoring logs, or debugging a model in real time secure shell access is now baked right into your workflow.

​
How It Works

  1. Generate your SSH keypair
  2. Upload your public key in your GPU Trader profile
  3. Select a container template and enable SSH
  4. Copy the script we generate for your OS
  5. Paste it into your terminal and you’re in!
We’ve published a full step-by-step SSH guide here with screenshots and usage examples.

Built for Developers

We designed this with flexibility in mind. Want to automate access? Feel free to modify the dowloaded script to support SCP or SFTP connections. SSH tunneling is now available for all templates, including custom templates, just look for the toggle when selecting your template.
