CONTRIBUTION - Created/tested Trudesk template for Caprover PaaS One-Click-Apps

[nativeit]

Is this a BUG REPORT or FEATURE REQUEST?:

• BUG
• FEATURE

What happened: I adapted the Docker Compose spec to be used with the fantastic Caprover PaaS one-click-app templates.

What did you expect to happen: An awesome open source help desk with supporting database and elasticsearch are provisioned, connected, and launched successfully behind a secured Nginx reverse proxy with Lets Encrypt SSL with minimal effort.

How to reproduce it (as minimally and precisely as possible):

1. Setup a server with Caprover.
2. Choose to deploy a new "One-Click App" and either select Trudesk from its presets (pending PR approval/merge), or copy/paste the code below into a generic Template.
3. Launch using default settings.
4. ?
5. Profit.

Anything else we need to know?: This has been tested (and is working a treat!) with Debian 10/11, using the settings found in the official Docker Compose file, Trudesk docs, and bits and pieces from previously closed issues. I will be submitting a PR to include Trudesk in Caprover's official One Click Apps directory, after which Trudesk can be deployed to a Caprover instance/cluster with just a few clicks.

Environment:

• Trudesk Version: 1.2.10
• OS (e.g. from /etc/os-release): Debian 11
• Node.JS Version: N/A
• MongoDB Version: 5.0
• Is this hosted on cloud.trudesk.io: No.
