Run the following commands on a fresh Ubuntu Focal 20.04 (x64) server:

Cloudron requires at least 1GB RAM, 20GB Disk space. Make sure the firewall does not block port 80 (http) and 443 (https). Cloudron does not support running on ARM, LXC or OpenVZ.
Once installation is complete, navigate to
https://<IP> in your browser and accept the self-signed
In Chrome, you can accept the self-signed certificate by clicking on
Advanced and then
Proceed to <ip> (unsafe). In Firefox, click on
Add Exception and
Confirm Security Exception.
At this point, the Cloudron setup wizard should appear.
Provide a domain like
example.com. The way Cloudron works is that the dashboard gets installed at
my.example.com, and apps are installed under subdomains that you specify like
chat.example.com, and so on.
It is perfectly safe to use a domain that is already in use as long as the
my subdomain is available.
When installing apps, Cloudron will never overwrite your existing DNS records and your existing subdomains will
remain intact. It is also possible to use a subdomain like
Next, select the DNS service in which the domain in hosted. If your service is not listed below, use the
- Digital Ocean
- Google Cloud DNS
- Linode DNS
The first domain added on Cloudron is called the
Primary Domain. The dashboard is made available
my subdomain of the primary domain. More domains can be added after installation in the
in the Domains view. The Primary Domain can be changed post installation.
If you are installing Cloudron on a home network, be sure to enable NAT loopback support on your router. By default, Cloudron will configure the DNS with the network's public (internet) IP and this option allows Cloudron to reach itself via the public IP.
Once DNS is setup, Cloudron will redirect to
https://my.example.com. The browser address bar
will show a green lock to indicate that the connection to your Cloudron is now secure.
Enter the adminstrator username, email and password for Cloudron.
The email address is used for password resets and notifications. It is local to your Cloudron and not sent anywhere (including cloudron.io).
Let's Encrypt requires a valid admin email
Cloudron sets up a Let's Encrypt account with the administrator's email. If this email address is not valid, Let's Encrypt will not issue certificates and Cloudron will fall back to using self-signed certs.
App Store Account
You are now ready to start installing apps! When you click on the
App Store link in the UI,
you will be prompted to create a cloudron.io account. This account is
used to manage your subscription and billing.
Security is a core feature of Cloudron and the default installation is already setup
to follow best practices. We do not recommend adding and modifying
iptables since Cloudron already does this (all unneeded ports are blocked).
To further harden security, we recommend configuring the VPS Firewall (in your VPS provider control panel) by following the firewall docs.
