Containers – SSH into running Container instances

You can now SSH into running Container instances using Wrangler. This is useful for debugging, inspecting running processes, or executing one-off commands inside a Container.

To connect, enable wrangler_ssh in your Container configuration and add your ssh-ed25519 public key to authorized_keys:

• wrangler.jsonc

  {
    "containers": [
      {
        "wrangler_ssh": {
          "enabled": true
        },
        "authorized_keys": [
          {
            "name": "<NAME>",
            "public_key": "<YOUR_PUBLIC_KEY_HERE>"
          }
        ]
      }
    ]
  }

• wrangler.toml

  [[containers]]
  [containers.wrangler_ssh]
  enabled = true
  
  [[containers.authorized_keys]]
  name = "<NAME>"
  public_key = "<YOUR_PUBLIC_KEY_HERE>"

Then connect with:

wrangler containers ssh <INSTANCE_ID>

You can also run a single command without opening an interactive shell:

wrangler containers ssh <INSTANCE_ID> -- ls -al

Use wrangler containers instances <APPLICATION> to find the instance ID for a running Container.

For more information, refer to the SSH documentation.
