IronBarcode offers complete compatibility with Docker, accommodating both Azure and AWS containers across Linux and Windows environments.
Docker provides developers with a streamlined method to package, distribute, and execute any application as a compact, self-contained container. These containers offer portability and can operate seamlessly across different computing environments.
For those new to using Docker in combination with .NET, we suggest checking out this informative article which provides a thorough guide on how to configure Docker for debugging and integrating it with Visual Studio projects.
Additionally, to ensure optimal use of IronBarcode on Linux platforms, please refer to our detailed IronBarcode Linux setup and compatibility guide.
For a straightforward setup of IronBarcode, the following 64-bit Linux distributions are recommended:
- Ubuntu 18 or newer
- Debian 10 or newer
- CentOS 7 or newer
It is advisable to utilize Microsoft's official Docker images for these environments. While partial support is available for other Linux distributions, they might necessitate manual configurations and additional installations of dependencies. For detailed instructions on configuring IronBarcode on Linux, refer to our Linux manual setup guide.
To seamlessly integrate IronBarcode into your Docker-based Linux setups, we advise utilizing the IronBarCode NuGet Package. This package is designed for ease of use across various operating systems including Windows, macOS, and Linux, ensuring a smooth workflow for developers.
Install-Package BarCodeIt is advisable to implement the IronBarCode NuGet Package for smooth development across Windows, macOS, and Linux environments.

ENTRYPOINT ["dotnet", "Example.dll"]Here's how to configure a CentOS 7 Docker container for .NET 7:
-
Base Image Preparation: Start with CentOS 7 as the base environment.
# Use CentOS 7 image FROM centos:7 as base # Setup Microsoft's package repository and install .NET runtime RUN rpm -Uvh https://packages.microsoft.com/config/centos/7/packages-microsoft-prod.rpm RUN yum install -y dotnet-runtime-7.0 WORKDIR /app
-
Development Environment Setup: Prepare the development environment in another stage of build to keep the build environment separate from runtime.
# Prepare the SDK environment FROM centos:7 as build # Install the Microsoft SDK package RUN rpm -Uvh https://packages.microsoft.com/config/centos/7/packages-microsoft-prod.rpm RUN yum install -y dotnet-sdk-7.0 WORKDIR /src
-
NuGet Package Restoration: Ensure that the IronBarCode's NuGet package is ready to use within the project.
# Restore the NuGet packages COPY ["Example/Example.csproj", "Example/"] RUN dotnet restore "Example/Example.csproj"
-
Application Building: Proceed to compile and build the .NET project.
# Copy the entire source folder, build the project COPY . . WORKDIR "/src/Example" RUN dotnet build "Example.csproj" -c Release -o /app/build
-
Publishing the Application: Create the publish artifact ready for deployment on any server.
# Setup the publish stage FROM build AS publish RUN dotnet publish "Example.csproj" -c Release -o /app/publish
-
Final Image Creation: Setup the final Docker image by copying the published files to the base image.
# Prepare the final runnable image FROM base AS final WORKDIR /app COPY --from=publish /app/publish . ENTRYPOINT ["dotnet", "Example.dll"]
This configuration ensures that the application is running with the latest .NET 7 framework on a CentOS 7 base, leveraging Docker's capabilities for isolated and replicable environments.
