Setting up IronWord in Docker Containers
IronWord is fully supported in Docker containers for both Linux and Windows environments, making it ideal for deployment on Azure, AWS, or any . NET-ready host.
Why Use Docker?
Docker lets you package and run IronWord as a lightweight, self-contained container. This ensures consistent behavior across development, testing, and production—especially valuable when generating or manipulating Word documents programmatically.
IronWord supports .NET 5-9, .NET Standard (2.x, 3.x), and .NET Framework 4.6.2+, all of which work seamlessly in Docker on Linux and Windows.
Recommended Linux Docker Distributions
We recommend the following 64‑bit Linux distros for smooth IronWord operation:
- Ubuntu 22.04+ (Jammy)
- Ubuntu 20.04 (Focal)
- Debian 11+ (Bullseye)
- CentOS7+
Use Microsoft’s official Docker images with the .NET runtime and SDK to simplify setup and dependency management
IronWord NuGet Package
IronWord is easily added to any .NET project through its NuGet package. Simply run the following command in the NuGet Package Manager Console, and it will add the library automatically:
Install-Package IronWord

- IronWord fully supports .NET5–9, .NET Standard (2.x, 3.x), and .NET Framework 4.6.2+.
- Install fonts if needed (e.g., fonts-liberation, ttf-mscorefonts-installer) on Linux containers for proper rendering.
