<@U019MFDTVDX> we usually recommend dynamic providers for this, but they aren't currently supported in Go. Your best bet is to use `user_data` in your cloud provider

Thanks! I'm using Hetzner Cloud. I'll give `user_data` a go

I'm really struggling to find any documentation for `user_data`, is there anything better than <https://www.pulumi.com/docs/intro/concepts/programming-model/#additional-examples>?

Take a look in this repo

Thanks for the link, though that on its own is almost beyond useless :joy:. I found some examples thanks to sourcegraph: <https://sourcegraph.com/search?q=repo:%5Egithub%5C.com/pulumi/examples%24+userData+lang:go+&amp;patternType=literal>

Managed to get it working with `userData`, thanks <@UCWG26BH7>. In the end I was able to make a single pulumi workflow that:
1. Adds an SSH key to my Hetzner account
2. Creates a Hetzner VM with said SSH key (installing docker on the host via `userData`)
3. Creates a Docker provider for controlling docker on the new VM via `<ssh://root>@&lt;ip&gt;`
4. Spins up my desired Docker container on the VM.
I was pretty happy with having it all working, but I had to introduce a little hack between steps 2 and 3 to dynamically update the `known_hosts` on my machine based on the new VMs host key. I've pushed it all to <https://github.com/johanbrandhorst/pulumi>. Would appreciate any feedback on the approach. I would be particularly interested in hearing whether it'd be possible to create a docker provider using the SSH connection I'm establishing inside the application, rather than relying on `ssh://`.
