Setting up IronOCR in Docker Containers
Want to OCR Images or Pdf Files in C#?
IronOCR now fully supports Docker, including Azure Docker Containers for Linux and Windows.
Why use Docker?
Docker enables developers to easily pack, ship, and run any application as a lightweight, portable, self-sufficient container, which can run virtually anywhere.
IronOCR and Linux Primer
If Docker with .NET is new to you, we recommend this excellent article on setting up Docker debugging and integration with Visual Studio projects. https://docs.microsoft.com/en-us/visualstudio/containers/edit-and-refresh?view=vs-2019
We also highly recommend you read our IronOCR Linux Setup and Compatibility Guide.
Recommended Linux Docker Distributions
We recommend the latest 64-bit Linux OS's below for "easy configuration" of IronPDF.
- Ubuntu 20
- Ubuntu 18
- Debian 11
- Debian 10 [Currently the Microsoft Azure Default Linux Distro]
We recommend using Microsoft's Official Docker Images. Other Linux distros are supported in part, but may require manual configuration using apt-get
. See our "Linux Manual Setup" guide.
Working Docker files for Ubuntu and Debian are included in this document:
IronOCR Linux Docker Installation Essentials
Use Our NuGet Package
We recommend using the IronOcr NuGet Package. It works when developing on Windows, macOS, and Linux.

Frequently Asked Questions
How can I deploy C# OCR applications in Docker containers?
You can deploy C# OCR applications in Docker containers by using IronOCR, a C# OCR library that integrates with Docker. You'll need to set up the Docker containers with the necessary packages like apt-utils
, libgdiplus
, and libc6-dev
, and use Microsoft's official Docker images for optimal performance.
Which operating systems are best for running IronOCR in Docker?
For running IronOCR in Docker, it is recommended to use the latest 64-bit Linux distributions such as Ubuntu 20, Ubuntu 18, Debian 11, and Debian 10, as they offer easy configuration and support.
How do I configure IronOCR on Azure Docker Containers?
To configure IronOCR on Azure Docker Containers, you would follow the same steps as for other Docker environments. Use the IronOcr NuGet package, set up the recommended Linux distributions, and ensure all necessary dependencies are included in your Dockerfile.
What are the steps to set up IronOCR using .NET 5 in Docker?
To set up IronOCR using .NET 5 in Docker, you need to create a Dockerfile that installs the IronOcr NuGet package, adds required packages like apt-utils
and libgdiplus
, and uses Microsoft's official .NET 5 Docker images for the base image.
Can IronOCR be used in Docker environments on Windows?
Yes, IronOCR can be used in Docker environments on Windows. The process involves using the IronOcr NuGet package and configuring the Dockerfile to include necessary dependencies and configurations specific to Windows operating systems.
What are the benefits of using Docker for hosting .NET OCR applications?
Using Docker for hosting .NET OCR applications allows for easy deployment, better resource management, and greater portability across different environments. Docker containers are self-sufficient, ensuring that the applications run consistently regardless of where they are deployed.
Is manual configuration required for non-recommended Linux distributions in Docker?
Yes, if you are using Linux distributions other than the recommended ones (Ubuntu 20, Ubuntu 18, Debian 11, Debian 10), you might need to perform manual configurations using apt-get
. Guidance on manual setup is available in the 'Linux Manual Setup' guide provided by IronOCR.
