-Caddy v2 Caddyfile
+a fancy docker image using [Caddy](https://caddyserver.com/) is also provided. have a look at the simple config file `Caddyfile`, it shows how to use http basic authentication, and automatic TLS for hands-free https 🎉
 
 ```sh
-myserver.com
-
-# gate access
-basic_auth {
-  root $2a$14$Zkx19XLiW6VYouLHR5NmfOFU0z2GTNmpkT/5qqR7hx4IjWJPDhjvG # password is "hiccup"
-  ro_user1 $2a$14$Zkx19XLiW6VYouLHR5NmfOFU0z2GTNmpkT/5qqR7hx4IjWJPDhjvG # password is "hiccup"
-  ro_user2 $2a$14$Zkx19XLiW6VYouLHR5NmfOFU0z2GTNmpkT/5qqR7hx4IjWJPDhjvG # password is "hiccup"
-}
-
-# named matcher for root user
-@isroot {
-  vars {http.auth.user.id} root
-}
-
-# proxy regular and read only instance
-handle @isroot {
-  reverse_proxy 127.0.0.1:8001
-}
-# route non-root user to read only instance
-handle {
-  reverse_proxy 127.0.0.1:8002
-}
+# checkout the caddy config, build, and run docker image
+% vim caddy.Dockerfile
+% docker build -t gossa-caddy -f caddy.Dockerfile .
+% sudo docker run -v ~/LocalDirToShare:/shared -v `pwd`/Caddyfile:/Caddyfile --net=host gossa-caddy
 ```
 
-then simply start the 2 gossa instances, and caddy
-
-```sh
-# start an instance in readonly
-% ./gossa -ro=true -p 8002 ~/folder &
-
-# start an instance with access to hidden files
-% ./gossa -k=false  -p 8001 ~/folder &
-
-# start caddy
-% ./caddy
-```
-
-### example 2 users on 2 different folders
-
-This sample Caddyfile will
- + enable https on the domain myserver.com (http will be automatically redirected to https)
- + password protect the access
- + route user1 to own folder
- + route user2 to own folder
- + share a folder between 2 users with a symlink
-
-<details>
-  <summary>Legacy Caddy v1 Caddyfile</summary>
-
-  ```sh
-  myserver.com
-  
-  proxy /user1 127.0.0.1:8001 { without /user1 }
-  proxy /user2 127.0.0.1:8002 { without /user2 }
-  
-  basicauth / user1 passworduser1
-  basicauth / user2 passworduser2
-  
-  rewrite {
-    if {>Authorization} is "Basic dXNlcjE6cGFzc3dvcmR1c2VyMQ=="
-    to /user1/{path}
-  }
-  
-  rewrite {
-    if {>Authorization} is "Basic dXNlcjI6cGFzc3dvcmR1c2VyMg=="
-    to /user2/{path}
-  }
-  ```
-</details>
-
-Caddy v2 Caddyfile
-
-```sh
-myserver.com
-
-basic_auth {
-  user1 $2a$14$Zkx19XLiW6VYouLHR5NmfOFU0z2GTNmpkT/5qqR7hx4IjWJPDhjvG # password is "hiccup"
-  user2 $2a$14$Zkx19XLiW6VYouLHR5NmfOFU0z2GTNmpkT/5qqR7hx4IjWJPDhjvG # password is "hiccup"
-}
-
-@user1auth {
-  vars {http.auth.user.id} user1 
-}
-handle @user1auth {
-  reverse_proxy 127.0.0.1:8001
-}
-
-@user2auth {
-  vars {http.auth.user.id} user2
-}
-handle @user2auth {
-  reverse_proxy 127.0.0.1:8002
-}
-```
-
-start 2 gossa instances, and caddy
-
-```sh
-# create symlink to share folder between 2 users
-% ln -s /path/shared test/user1
-% ln -s /path/shared test/user2
-
-# start gossa & caddy
-% ./gossa -p 8001 -symlinks=true test/user1 &
-% ./gossa -p 8002 -symlinks=true test/user2 &
-% ./caddy
-```
-
-## nginx setup
-
-In order to allow for larger uploads, it's recommended to increase the maximum body size on your nginx config :
-
-```
-# increase maximum request size
-client_max_body_size 100M;
-```
+a docker-compose example image is also provided. running docker compose should be straightforward : `docker-compose up .` have a look in `docker-compose.yml` for further configuration.
