# Role `nginx`
Ensures nginx is installed from the NGINX repos and setup as specified via the arguments.
## Supported Distributions
The following distributions are supported:
- Debian 11
- Debian 12
## Required Arguments
None.
## Optional Arguments
- `nginx__deploy_redirect_conf`: Whether or not to deploy a config redirecting from HTTP to HTTPS, while still forwarding the `/.well-known/acme-challenge/` to localhost Port 31820 for certificate issuing.
See [`files/redirect.conf`](./files/redirect.conf) for the configuration that would be deployed.
Defaults to `true`.
- `nginx__deploy_tls_conf`: Whether or not to deploy a config configuring some TLS settings reasonably.
See [`files/tls.conf`](./files/tls.conf) for the configuration that would be deployed.
Defaults to `true`.
- `nginx__deploy_logging_conf`: Whether or not to deploy a config configuring logging to journald.
See [`files/logging.conf`](./files/logging.conf) for the configuration that would be deployed.
Defaults to `true`.
- `nginx__configurations`: List of nginx configurations to ensure are deployed.
- `nginx__configurations.*.name`: This name with `.conf` appended will be used for the configurations file name under `/etc/nginx/conf.d/`.
`tls`, `redirect` and `logging` are reserved names.
- `nginx__configurations.*.content`: This configurations content.
- `nginx__use_custom_nginx_conf`: Whether or not to use a custom `/etc/nginx/nginx.conf`.
If set to true, you must provide the content for a custom `nginx.conf` via `nginx__custom_nginx_conf`.
Defaults to `false`.
- `nginx__custom_nginx_conf`: The content to use for the custom `nginx.conf`.
Needs `nginx__use_custom_nginx_conf` to be set to true to work.
You should probably still make sure that your custom `nginx.conf` includes `/etc/nginx/conf.d/*.conf`, so that the other configuration files still work.
## Config Template
Here's a config template, which can be used for new NGINX site configs, which you can supply to this role using the `nginx__configurations` argument.
Just replace the placeholder values with real ones and extend and edit it as needed.
