IronPDF Linux Compatibility & Setup Guide

IronPDF supports Linux for .NET 6, 5 and .NET Core applications, as well as Docker, Azure, AWS, macOS and (naturally) Windows.

We recommend using .NET Core 3.1 and any other runtimes marked as LTS by Microsoft because they have guaranteed long term support and are generally well tested on Linux.

No code changes are required to run on IronPDF Linux. Generally IronPDF works out of the box thanks to hundreds of hours of testing and configuration by our engineers.

Linux support is important because many cloud service such as Azure Web Apps, Azure Functions, AWS EC2, AWS Lambda, Azure Devops Docker rely heavily on Linux. At Iron Software we use these cloud tools regularly and understand that many of our Enterprise and SAAS customers do too,

Officially Supported Linux Distros

We officially support and recommend the latest 64 bit Linux OS's below for "zero configuration" setup of IronPDF.

  • Ubuntu 20
  • Ubuntu 18
  • Ubuntu 16
  • Debian 11 [Currently the Microsoft Azure Default Linux Distro]
  • Debian 10
  • CentOS 8
  • Fedora Linux 33
  • Amazon AWS Linux 2 Read the AWS Lambda Setup Guide for IronPdf

Please Read "Other Linux Distros" below for advice on installing IronPdf on a version of Linux which is not officially supported.

We recommend using Microsoft's Official Docker Images . Other Linux distros are supported in part, but may require manual configuration using apt-get. See "Common Dependency Patterns for Linux" at the end of this document.

Linux Automatic Setup

The default setting LinuxAndDockerDependenciesAutoConfig true will automatically attempt to install all dependencies for IronPDF to run on Linux. The first html-to-pdf operation may take longer than usual packages that are installed.

IronPdf.Installation.LinuxAndDockerDependenciesAutoConfig = true;
IronPdf.Installation.LinuxAndDockerDependenciesAutoConfig = true;
IronPdf.Installation.LinuxAndDockerDependenciesAutoConfig = True

chmod 755 IronCefSubprocess
# (IronCefSubprocess is normally found at bin/runtimes/linux-x64/)

Please also read our documentation on our official support IronPdf for AWS Lambda that includes installation and logging on the Amazon cloud platform.

Fedora Linux Compatibility

Fedora Linux is supported.

We support Fedora Linux 33 out of the box with zero configuration.

  • Support Chrome and WebKit based HTML to PDF rendering Engines
  • Officially Support .NET Core 3.1 LTS and .NET 5 runtimes
  • We run comprehensive smoke tests on this platform before every release

Manual Fedora Linux Setup If you wish to manually install or your app can not be run with sudo admin privileges. This may also help with older or newer builds of Fedora Linux.

Set IronPdf.Installation.LinuxAndDockerDependenciesAutoConfig = false;

dnf -y install glibc-devel
dnf -y install nss
dnf -y install at-spi2-atk
dnf -y install libXcomposite
dnf -y install libXrandr
dnf -y install mesa-libgbm
dnf -y install alsa-lib
dnf -y install pango
dnf -y install cups-libs
dnf -y install libXdamage
dnf -y install libxshmfence

chmod 755 IronCefSubprocess
# (IronCefSubprocess is normally found at bin/runtimes/linux-x64/)

Alpine Linux Compatibility

Alpine Linux is not supported. We wish we could but we can't. Frankly we like Alpine and hope this project continues and grows. As of 2022, Alpine still uses outdated "musl" C language libraries that do not allow chromium developers to fully support this OS yet.

Other Linux Distros

You can also manually install the IronPDF prerequisites for Linux using apt-get hfs and yum This allows you to use IronPDF on many unsupported linux distros.

Generally during installation for the first time IronPDF will throw exceptions to tell you of any necessary system dependancies.

  • IronCefSubprocess mentioned below is a binary within your application's bin folder. You may need to specify an exact path which may be in the runtimes subdirectory of bin.
  • You may need sudo privileges.

If you are uncertain how to proceed with an unlisted Linux OS; investigate the dependancies for Chromium browser on that OS.

If you want to vote for offical support for a different linux distro, please contact developers@ironsoftware.com with your request.

Common Dependency Patterns for Linux Please also study the dependency packages for other linux OS's above.

apt update
apt install -y libc6-dev
apt install -y libgtk2.0-0
apt install -y libnss3
apt install -y libatk-bridge2.0-0
apt install -y libx11-xcb1
apt install -y libxcb-dri3-0
apt install -y libdrm-common
apt install -y libgbm1
apt install -y libasound2
apt install -y libappindicator3-1
apt install -y libxrender1
apt install -y libfontconfig1
apt install -y libxshmfence1

chmod 755 IronCefSubprocess
# (IronCefSubprocess is normally found at bin/runtimes/linux-x64/)

IronCefSubprocess

IronCefSubprocess is a binary file within your application's bin folder. It needs to be executable by the .NET process.

E.g. (path may vary)

chmod 755 bin/runtimes/linux-64/IronCefSubprocess

dotnet single-file publishing in Linux

If you choose to export your project as single-file publishing on Linux, this is how to do it.

dotnet publish -r linux-x64 /property:PublishProfile=FolderProfile /bl

Temp File Paths

Developers may need to specify a writable directory where temporary files can be created for some use cases.

A common, safe value for this path is /tmp/ in Linux, but ultimately it must be a path where the user can read and write files.

//set IronPDF Temp Path
string tmpPath =  @"/tmp/"; 

IronPdf.Logging.Logger.LogFilePath = tmpPath;
Environment.SetEnvironmentVariable("TEMP", tmpPath, EnvironmentVariableTarget.Process);
Environment.SetEnvironmentVariable("TMP", tmpPath, EnvironmentVariableTarget.Process);
IronPdf.Installation.TempFolderPath = tmpPath;
IronPdf.Installation.CustomDeploymentDirectory = tmpPath;
//set IronPDF Temp Path
string tmpPath =  @"/tmp/"; 

IronPdf.Logging.Logger.LogFilePath = tmpPath;
Environment.SetEnvironmentVariable("TEMP", tmpPath, EnvironmentVariableTarget.Process);
Environment.SetEnvironmentVariable("TMP", tmpPath, EnvironmentVariableTarget.Process);
IronPdf.Installation.TempFolderPath = tmpPath;
IronPdf.Installation.CustomDeploymentDirectory = tmpPath;
'set IronPDF Temp Path
Dim tmpPath As String = "/tmp/"

IronPdf.Logging.Logger.LogFilePath = tmpPath
Environment.SetEnvironmentVariable("TEMP", tmpPath, EnvironmentVariableTarget.Process)
Environment.SetEnvironmentVariable("TMP", tmpPath, EnvironmentVariableTarget.Process)
IronPdf.Installation.TempFolderPath = tmpPath
IronPdf.Installation.CustomDeploymentDirectory = tmpPath
