docker nginx reverse proxy, mariadb, wordpress, nextcloud

I just migrated to a VPS and nothing works as planned, or at least as on other servers I've setup over years (since the 90s). I don't know if cpanel/WHM is mucking around but here his what I want. Docker containers: *[login to view URL] -> jwilder/nginx-proxy [login to view URL] -> wordpress:1000 [deny external] -> mariadb for wordpress:1000 [login to view URL] -> nextcloud:2000 [deny external] -> mariadb for nextcloud:2000 Note that the VPS has NGINX and APACHE installed to make the SMTP work. This needs to work at the end too. (can I get rid of these and have just docker containers????) Plan and simple, there are a thousand websites saying how to do this. I'm clearly too stupid to google it and make it work. I'll give root access to VPS and you send me the commands. I've taken a server snapshot and I'll restore and run the commands. If I can get it to stand up with the commands, then payment will be released. Server is running Centos6.10 kvm with WHM 70.0.51
