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:

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

[[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.
