-# Problem
+# Self-hosting setup
-* failed to solve: failed to read dockerfile: open /var/lib/docker/tmp/buildkit-mount1013749728/Dockerfile: no such file or directory
+## Deployed apps
-Trying to solve this :D
+### Public hosting
+* `pumppi.dev` rust test app
+* `pumppi.dev` ssh
+* `tsoha.pumppi.dev` timetrials
+* `bort.pumppi.dev` closest bus-stop times
+* `reaktor.pumppi.dev` backend for reaktor 2023 summer job application
+* `cal.pumppi.dev` calendar
+* minecraft server (currently not running)
 
-Solved! Pumppistatus was missing a Dockerfile :DDD
+### Ports on server
+* `tsoha.pumppi.dev`      5000
+* `reaktor.pumppi.dev`    5050
+* radicale                5232
+* Postgres-database:      5432
+* `bort.pumppi.dev`       5500
+* `brewery.pumppi.dev`    5555
+* `pumppi.dev`:           8000
+* `mine.pumppi.dev`       25565
+
+
+### Local hosting
+* Mysql
+* Postgres
+* Nginx
+* ddclient
+
+# Howto
+## Connecting to router
+```bash
+ssh -L 8080:<ROUTER_IP>:<ROUTER_PORT> pumppi.dev
+```
+And voila, the router is accessible at http://localhost:8080.
+
+## Add new subdomain
+### Namecheap
+First add new subdomain to `namecheap` with `A + Dynamic DNS Record`.
+The IP can be anything, it will be overwritten by 'ddclient`.
+
+### DDClient
+Next ssh into the server and add the new subdomain to the 
+`ddclient`'s config located in the `/etc/ddclient/ddclient.conf`. 
+After editing the config, restart the service with
+
+```bash
+sudo systemctl restart ddclient.service
+```
+Check if the IP has updated in `namecheap` for the new domain.
+If the IP has not changed, don't continue. FIX IT.
+
+### Nginx
+
+Edit or add a config file in `/etc/nginx/sites-available/<your-domain-name>`.
+
+
+```cfg
+server {
+    listen 443 ssl;
+    listen [::]:443 ssl;
+
+    server_name <your_server_name>;
+    # ssl_certificate /etc/letsencrypt/live/<YOUR_DOMAIN_NAME>/fullchain.pem; # managed by Certbot
+    # ssl_certificate_key /etc/letsencrypt/live/<YOUR_DOMAIN_NAME>/privkey.pem; # managed by Certbot
+    # include /etc/letsencrypt/options-ssl-nginx.conf;
+
+    location / {
+        proxy_pass http://127.0.0.1:<PORT_OF_THE_APP>;
+    }
+
+}
+```
+
+#### Note
+Leave the ssl cert things commented for now. Before running `certbot` having
+the lines uncommented will result in an error. The files do not exist yet!
+
+After editing we can test if the new config is valid with
+```bash
+nginx -t
+```
+
+You might need sudo for this.
+
+
+### Certbot
+Next we move to getting the certifications. With `nginx` its dead
+simple. Just run
+```bash
+sudo certbot certonly --nginx
+```
+and it should work. If there are errors, fix them.
+And that should be it.
+
+### After all
+Make sure your process is running and it should be served to the
+outside world.
+
+Happy self hosting :)
