Getting started

[KevM]

Hi you all,

I'm new to WHMCS and want to get started. 
I'm a bit confused right now by all the input here and in the WHMCS Docs. 

Therefore, I hope maybe one or some of you can clear my mind. 

Could someone answer these questions?

1.  Is it a promising idea to run WHMCS in a Docker Container?
2. I understand that nginx is not officially supported/recommended. However, which tool should I use then to secure the WHMCS Instance?
3. Has anyone tried traefik instead of nginx for WHMCS yet? If so, would this be a better solution?
4. Is there any best practice script or compose file for a WHMCS environment? I have seen this which was created by @leemahoney3  (Thanks for this) but I don't know if I should follow this based on point two.
5.   If you wouldn't use Docker - what kind of Server environment would you use? I was thinking of using something like Cloud Server Mieten » Ab 5€ / Monat mit Windows o. Linux (ionos.de) or linode / hetzner. But I'm not sure. 

I'm looking forward to your opinions, please note that I'm more on the "business side" of the business than the IT side however, I try to learn and grow - so feel free to be detailed. 

Thanks and Kind regards from Germany,

Kevin (aka KevM)
