thanks @LZRS. can you take a look at this PR: #57 and see there's anything else that needs to be added?

[jingtang10]

i'd much rather use the google cloud url than to tie this to nawi. can you update this please?

[jingtang10]

how are you deploying this on gcp? what if we need to scale up? is there a way to tie this to a fixed url but not an ip? thanks.

@jingtang10 Are you able to create a subdomain under ohs.dev that we can use? Something like kotlin-fhirpath.ohs.dev.

For a start we can point kotlin-fhirpath.ohs.dev to 35.246.242.55 where we currently are hosting the dev environment.

@jingtang10 Would you be able to get such a domain?

[jingtang10]

no the ohs.dev domain is being transferred. we need to set it up later.

[jingtang10]

does gcp not allow an url, which is more permanent than an ip?

[qiarie]

@jingtang10 Let me do some research on this. I will share an update

I'm excited to see this get added!
Can you setup a static config file somewhere so we can test things out before it's properly included...
Details here:
https://github.com/brianpos/fhirpath-lab/blob/develop/docs/custom-configuration.md
Don't know if you want to include the early adopter flag.

Is this something that you think you'll have cooking for DevDays next week?
Would be a nice little surprise annoucenment at the meeting.
