# Prerequisites

Zonemaster comes with documentation for and has been tested on the operating systems
and processor architecture listed below.

## Supported processor architectures

* x86_64 / amd64

## Supported operating system versions

| Operating System | Version |
|:-----------------|:-------:|
| [Debian]         | 13      |
| [Docker]         | n/a     |
| [FreeBSD]        | 14      |
| [Rocky Linux]    | 8       |
| [Rocky Linux]    | 9       |
| [Rocky Linux]    | 10      |
| [Ubuntu]         | 22.04   |
| [Ubuntu]         | 24.04   |

Only the latest long-term supported version of Debian and FreeBSD, respectively,
is supported. All long-term supported versions of Rocky Linux and Ubuntu are
supported, unless such a version has end of support before the expected next
release of Zonemaster.

Only the Docker images provided by the Zonemaster project on [Docker Hub] are
supported. Currently only Zonemaster-CLI is supported on Docker. Docker itself
can run on any of the [Docker] supported OSs (Linux, macOS and Windows).

## Supported database engine versions

| Operating System | MariaDB | PostgreSQL |
|------------------|---------|------------|
| Debian 13        | 11.8    | 17         |
| Docker           | n/a     | n/a        |
| FreeBSD 14       | 8.0 (*) | 17         |
| Rocky Linux 8    | 10.3    | 10         |
| Rocky Linux 9    | 10.5    | 13         |
| Rocky Linux 10   | 10.11   | 16         |
| Ubuntu 22.04     | 10.6    | 14         |
| Ubuntu 24.04     | 10.11   | 16         |

* (*) FreeBSD uses MySQL, not MariaDB.
* SQLite is bundled in Perl DBD::SQLite and loaded as a dependency to
  Zonemaster-Backend.
* Zonemaster Backend has been tested with the combination of OS and database
  engine version listed in the table above.
* Zonemaster depends on functionality introduced in PostgreSQL version 10, and
  earlier versions of PostgreSQL are as such not supported.
* Zonemaster Backend has not been published on [Docker Hub].
