== Deploying it to Hetzner Cloud
A deployment to Hetzner Cloud is composed of mainly three things:
- A server.
- A firewall.
- A private network.
First, we will set up the latter two before creating the server. footnote:[Though, it can be created in any order, it's just personal preferences at this point.]
Setting up a firewall is pretty simple as the TCP/UDP ports is patterned after the allowed IP ranges in the host configuration.
You can set up a firewall from Hetzner Cloud web UI but you can also deploy one with `hcloud`.
[source, shell]
----
hcloud firewall create --name plover-firewall
hcloud firewall add-rule plover-firewall --direction in --protocol tcp --port 22 --description "Secure shells"
hcloud firewall add-rule plover-firewall --direction in --protocol tcp --port 80 --description "HTTP server"
hcloud firewall add-rule plover-firewall --direction in --protocol tcp --port 433 --description "HTTPS server"
hcloud firewall add-rule plover-firewall --direction in --protocol tcp --port 389 --description "LDAP server"
hcloud firewall add-rule plover-firewall --direction in --protocol tcp --port 636 --description "LDAPS server"

Next up, the networking setup which is composed of a public IP used for accessing some services and a private network used to communicate inside of the network.
However, the main reason we have a private network is to setup a VPN service.
You can create one from Hetzner Cloud web UI.
If you want to create with `hcloud`, however...
[source, shell]
----
hcloud network create --name plover-local --ip-range 172.16.0.0/12
----
To deploy this to Hetzner Cloud, just initialize a server and run link:https://github.com/elitak/nixos-infect/[nixos-infect] script.
As an example, you can run the server with the following link:https://community.hetzner.com/tutorials/basic-cloud-config[cloud config].
