Hey @tehcyx, anything else I need to do for this PR? Really appreciate your work on this provider!

Hi @JackFlukinger, no you're good. Just haven't gotten around testing this. Doing that now, as well as running tests on the PR.

Ah, I do see one small problem now that I look back. Oops! Fixing & committing now

[tehcyx]

So what I found is, that we should change the function like this:

func kindConfigNodeMountFields() map[string]*schema.Schema {
	s := map[string]*schema.Schema{
		"host_path": {
			Type:     schema.TypeString,
			Optional: true,
		},
		"container_path": {
			Type:     schema.TypeString,
			Optional: true,
		},
		"propagation": {
			Type:     schema.TypeString,
			Optional: true,
		},
		"readonly": {
			Type:     schema.TypeBool,
			Optional: true,
		},
		"selinux_relabel": {
			Type:     schema.TypeBool,
			Optional: true,
		},
	}
	return s
}

Since we already have the mapping done:

edit: Actually you uncovered that I missed adding three options here to the mapping.

Yeah, I just saw that, I think read_only is more idiomatic. I'll add propagation & selinux_relable real quick

True. Thanks for adding the other two.

Cool, done, let me know if that looks all good to you :)

Testing, then probably merging if nothing pops up.
