# Risotto dataset simple examples
|
||
|
||
This tutorial aims to show how create a dataset to deploy a [Caddy](https://caddyserver.com/) server via Risotto.
|
||
|
||
Attention it has no other virtues than to be educational. It is not intended for production use.
|
||
|
||
See [Rougail documentation for more details about dictionaries, templates and patches](https://cloud.silique.fr/gitea/risotto/rougail/src/branch/main/doc/README.md).
|
||
|
||
The project can be divided into three application services:
|
||
|
||
- caddy-common: an application service containing the information common to the two other application services
|
||
- caddy-https: a standalone http/https server
|
||
- caddy-https-rp: a https only server served behind a reverse proxy
|
||
|
||
## caddy-common
|
||
|
||
Start by creating the project tree:
|
||
|
||
```
|
||
seed/caddy-common/
|
||
├── dictionaries
|
||
├── templates
|
||
└── manual
|
||
└── image
|
||
└── preinstall
|
||
```
|
||
|
||
Then describe the application service in [seed/caddy-common/applicationservice.yml](seed/caddy-common/applicationservice.yml).
|
||
|
||
Also a dictionary [seed/caddy-common/dictionaries/20-caddy.yml](seed/caddy-common/dictionaries/20-caddy.yml) with
|
||
|
||
- the activation of the caddy service in the "multi-user" target. This service needs some templates:
|
||
|
||
- the main configuration's [/etc/caddy/Caddyfile](seed/caddy-common/templates/Caddyfile) to include other /etc/caddy/Caddyfile.d/\*.caddyfile
|
||
- /etc/caddy/Caddyfile.d/risotto.caddyfile with appropriate configuration (this file is not part of this application service)
|
||
- a [sysusers](https://www.freedesktop.org/software/systemd/man/sysusers.d.html) file [/sysusers.d/0caddy.conf](seed/caddy-common/templates/sysuser-caddy.conf) to create the system user "caddy"
|
||
- a [tmpfiles](https://www.freedesktop.org/software/systemd/man/tmpfiles.d.html) file [/tmpfiles.d/0caddy.conf](seed/caddy-common/templates/tmpfile-caddy.conf) to create the directory "caddy_root_directory" and volatile directory "/var/lib/caddy"
|
||
|
||
- a family "caddy" (Caddy web server) with a filename variable "caddy_root_directory" (The root path of the site) with default value "/srv/caddy".
|
||
|
||
Finally, create a script to build the image with the caddy package: [seed/caddy-common/manual/image/preinstall/caddy.sh](seed/caddy-common/manual/image/preinstall/caddy.sh).
|
||
|
||
## caddy-https
|
||
|
||
Start by creating the project tree:
|
||
|
||
```
|
||
seed/caddy-https-rp/
|
||
├── dictionaries
|
||
└── templates
|
||
```
|
||
|
||
Then describe the application service in [seed/caddy-https/applicationservice.yml](seed/caddy-https/applicationservice.yml) with OS and caddy-common dependencies.
|
||
|
||
Also create a dictionary [seed/caddy-https/dictionaries/25-caddy.yml](seed/caddy-https/dictionaries/25-caddy.yml) to define the variables:
|
||
|
||
- caddy_domain: the domain where Caddy should listen to
|
||
- caddy_ca_file, caddy_crt_file and caddy_key_file: certificat for this domain
|
||
- redefine the variable incoming_ports to open the ports 80 and 443
|
||
|
||
And new templates:
|
||
|
||
- [seed/caddy-https/templates/risotto.caddyfile](seed/caddy-https/templates/risotto.caddyfile)
|
||
- [seed/caddy-https/templates/ca_HTTP.crt](seed/caddy-https/templates/ca_HTTP.crt)
|
||
- [seed/caddy-https/templates/caddy.key](seed/caddy-https/templates/caddy.key)
|
||
- [seed/caddy-https/templates/caddy.crt](seed/caddy-https/templates/caddy.crt)
|
||
|
||
## caddy-https-rp
|
||
|
||
Start by creating the project tree:
|
||
|
||
```
|
||
seed/caddy-https-rp/
|
||
├── dictionaries
|
||
├── patches
|
||
└── templates
|
||
```
|
||
|
||
Then describe the application service in [seed/caddy-https-rp/applicationservice.yml](seed/caddy-https-rp/applicationservice.yml) with OS, caddy-common and reverse-proxy-client dependencies.
|
||
|
||
By default, reverse proxy certificate is only readable by "root" user. In the dictionary [seed/caddy-https-rp/dictionaries/25-caddy.yml](seed/caddy-https-rp/dictionaries/25-caddy.yml) we change the user to "caddy".
|
||
|
||
And add Caddy configuration's file [seed/caddy-https-rp/templates/risotto.caddyfile](seed/caddy-https-rp/templates/risotto.caddyfile).
|
||
This template use mainly variables defined in reverse-proxy application service.
|
||
|
||
Finally add a patch to modify Caddyfile to not starts Caddy in port 80: [seed/caddy-https-rp/patches/Caddyfile.patch](seed/caddy-https-rp/patches/Caddyfile.patch).
|
||
Patches should only use if a template file is define in an other dataset. You should instead add a condition in the template. But for educational reasons we made a patch in this case.
