Hi David, thank you for responding. 

So its a standard New rails project with nothing really added as extras. The classes in the views are like the code below:

```
<dd class="mt-4 flex flex-auto flex-col text-base/7 text-sky-100">
    <p class="flex-auto">
              Follow the email instructions to provide your ID to allow use of
              our systems
    </p>
</dd>
```

And the Dockerfile is the boilerplate is the one that comes with a new rails project when setting up. Im confused lol...

```
# syntax=docker/dockerfile:1
# check=error=true

# This Dockerfile is designed for production, not development. Use with Kamal or build'n'run by hand:

```

I setup a new project and added the --css tailwinind flag and added a quick scaffhold, then setup a fresh server and deployed. This is the output on production on a fresh install and droplet! In dev its fine... Its stripped the styling out.

Ok, so managed to fix the issue...

In the Settings in Docker I switched to Docker VMM, but don't know if that helped or not. What I ended up doing was to change the `config.assets.compile` to `false` and then added `config.assets.manifest = Rails.root.join('config', 'manifest.json')`. I did leave it on Docker VMM in docker though so maybe it helped.

Not sure why the `config.assets.compile` was set to `true`. Likely something I changed when messing around trying to get it to work.
