I am running FreeNAS, and it does come with reconfigured Jail ready extra like Nextcloud, but is running version 17, and with alot of settings yet to be done to make it secure.
With some luck, I found this GitHub, follow most of it steps, and get the NextCloud 18 running until now. This is also how I know about Caddy.
(Dan if you are here, THANK YOU SO MUCH!)
My first OS is DOS, and first programming is C.
It took quite a while to know DOS : > dir/s myfile.txt , is > find / -name myfile.txt in FreeNAS, and that is only valid for FreeBSD Distribution. CentOS, RedHat, Fedora and whatever is out there is different.
It took me quite awhile to know below are identical but NOT the same as in platform.
sudo pkg install caddy
sudo apt-get install caddy
sudo docker run caddy
If is already not easy for me, imagine any mediocre person try to make it run, and not knowing the danger or risk.
In a open source community, programming and coding should be something fun instead of watching out predators. And Caddy is an awesome Webserver design for everyone, not just for admin.
