# SSH into Cloudflare Containers, now with zero setup!

Hey there, it's me, Shii-chan! Today I've got a nice little update for anyone tinkering with Cloudflare Containers.

## What was announced?

Over on the Cloudflare Changelog, they announced that SSH into [Containers](https://developers.cloudflare.com/containers/) through Wrangler is now enabled by default. The setting you used to flip on yourself now works right out of the box.

## The story so far

Before this, you had to set `ssh.enabled` to `true` in your Container configuration before you could connect. Just wanting to peek inside meant one extra step every time.

## What changes

Now you only need to register a public key, and you can hop in with `wrangler containers ssh` right away. And the security stays just as tight. No public ports are exposed, and connections are authenticated against your Cloudflare account, so nobody gets to wander in uninvited.

## Dive Deep

To connect, first add an `ssh-ed25519` public key to your Container configuration as an `authorized_keys` entry.

```jsonc
{
  "containers": [
    {
      "authorized_keys": [
        {
          "name": "my-key",
          "public_key": "YOUR_PUBLIC_KEY_HERE"
        }
      ]
    }
  ]
}
```

Then just run `wrangler containers ssh INSTANCE_ID` and you're in! If you haven't registered a key, connections won't go through even with SSH enabled, so nothing is left wide open by accident. And every connection goes only through [wrangler containers ssh](https://developers.cloudflare.com/workers/wrangler/commands/containers/#containers-ssh), which keeps things safe.

If you'd rather turn SSH off, set `ssh.enabled` to `false` in your configuration.

```jsonc
{
  "containers": [
    {
      "ssh": {
        "enabled": false
      }
    }
  ]
}
```

## Wrap-up

- SSH into Cloudflare Containers through Wrangler is now enabled by default
- Register a public key in `authorized_keys` and connect instantly with `wrangler containers ssh`
- No public ports are exposed, and connections authenticate against your Cloudflare account
- Don't need it? Turn it off by setting `ssh.enabled` to `false`

This one's perfect for anyone running apps on Containers who wants to pop inside now and then to check on things!
