I would like to deploy OpenRemote using OVHCloud with an ip address corresponding to the domain name.
If I change the domain name localhost to my own in the docker compose file, will this allow the docker to run in the cloud or will the docker remain local to the base computer?
If I understand correctly with this localhost configuration everything runs locally in the computer. What about if you use an OVHCloud and how is that set up?
Yes you are correct as long as your DNS A record resolves to the IP address of your cloud server and ports 80 and 443 are accessible then the proxy container will auto generate your TLS certificate using the built in certbot functionality.
Running in the cloude or within a LAN is no different, just typically within a LAN you would be behind some sort of NAT based router which would require port forwarding to your instance.
