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`:

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

```toml
[[containers]]
[containers.wrangler_ssh]
enabled = true

[[containers.authorized_keys]]
name = "<NAME>"
public_key = "<YOUR_PUBLIC_KEY_HERE>"
```

Then connect with:

```sh
wrangler containers ssh <INSTANCE_ID>
```

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

```sh
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](https://developers.cloudflare.com/containers/guides/ssh/).
