Tweaks I needed for my installation

[toastboy70]

Hi,

Thanks for this work, it's very useful to me!

I hope I've got the procedure right: I'm more used to Mercurial than git. These are patches I needed to make nginx work with my collection of containers. In particular I needed to tweak the template to get it to work with containers where I was forced to change the exposed ports to avoid clashes, e.g.:

version: '3'

services:
  jira:
    image: "cptactionhank/atlassian-jira-software"
    container_name: jira
    restart: unless-stopped
    environment:
      - PUID=1000
      - PGID=1000
      - VIRTUAL_HOST=jira.example.com
      - VIRTUAL_PORT=28080
      - LETSENCRYPT_HOST=jira.example.com
      - LETSENCRYPT_EMAIL=bots@example.com
    ports:
      - "28080:8080"
    volumes:
      - "./jira:/var/atlassian/jira"

I found I needed to replace instances of Port with HostPort and all was well. The other commits were to make sure the nginx container was restarted when the host restarts, and just some .gitignore housekeeping.

Sorry for the delay, @almereyda could you take a look please?
