Reverse proxy (proxy_pass) a docker port with nginx and use certbot for https

// i managed to do it with docker-compose, might also work with docker run or whatever but idk

i made this specifically for ッツ jp reader cuz i wanted to self host it myself, not like i dont trust that fella but it is what it be

check to see if the containter is running with

docker ps

u should see the port it's running on, in my case it s 9010:

If you visited yoursite.com:9010 it should work as it should, however it wont be secure cuz no https

this guide assumes u wanna run it on a subdomain, so

add this in ur dns records:

ttureader.yoursite.com - IPv4 (A record) to ur servers IPv4

ttureader.yoursite.com - IPv6 (AAAA record) to ur servers IPv6

optionally do the same thing but with www.ttureader.yoursite.com

Then, create an nginx conf file, name it however u like

nano /etc/nginx/sites-available/ttureader

paste the following inside and change the domain name (yoursite.com) and the port if it's different (http://localhost:9010)

server {
    server_name ttureader.**yoursite.com** www.ttureader.**yoursite.com**;
    location / {
        proxy_pass http://localhost:9010;

    }

    listen 80;
    listen [::]:80;
}

ln -s /etc/nginx/sites-available/ttureader /etc/nginx/sites-enabled

systemctl reload nginx

Now when u visit ttureader.yoursite.com it should correctly redirect to ッツs reader

for https, quite simple, run

certbot --nginx

either select all domains or just the 2 we made, wait until it's resolved and voila ure done

if u were to open the conf file, ud see it has cerbot has certbotted all over it, hopefully it says congratulations
