Configurando o IronOCR em Contêineres Docker

Curtis Chau

Updated: 29 de junho de 2026

Quer Realizar OCR em Imagens ou Arquivos Pdf em C#?

O IronOCR agora oferece suporte total ao Docker, incluindo Contêineres Docker do Azure para Linux e Windows.

Por que usar Docker?

Docker permite que os desenvolvedores empacotem, enviem e executem facilmente qualquer aplicação como um contêiner leve, portátil e autossuficiente, que pode ser executado virtualmente em qualquer lugar.

IronOCR e Introdução ao Linux

Se o Docker com .NET é novo para você, recomendamos este excelente artigo sobre como configurar a depuração e integração do Docker com projetos do Visual Studio. https://docs.microsoft.com/en-us/visualstudio/containers/edit-and-refresh?view=vs-2019

Também recomendamos fortemente que você leia nosso Guia de Configuração e Compatibilidade do IronOCR para Linux.

Distribuições Linux recomendadas para Docker

Recomendamos os sistemas operacionais Linux de 64 bits mais recentes listados abaixo para uma "configuração fácil" do IronPDF.

Ubuntu 20
Ubuntu 18
Debian 11
Debian 10 [Atualmente o padrão Linux do Microsoft Azure]

Recomendamos usar as Imagens Docker Oficiais da Microsoft. Outras distribuições Linux são parcialmente suportadas, mas podem requerer configuração manual usando apt-get. Veja nosso guia de "Configuração Manual do Linux".

Arquivos Docker funcionais para Ubuntu e Debian estão incluídos neste documento:

Essenciais de Instalação do Docker para Linux do IronOCR

Use Nosso Pacote NuGet

Recomendamos o uso do pacote NuGet IronOCR. Ele funciona ao desenvolver no Windows, macOS e Linux.

Perguntas frequentes

Como posso implantar aplicativos OCR em C# em contêineres Docker?

Você pode implantar aplicativos OCR em C# em contêineres Docker usando o IronOCR, uma biblioteca OCR em C# que se integra ao Docker. Será necessário configurar os contêineres Docker com os pacotes necessários, como apt-utils , libgdiplus e libc6-dev , e usar as imagens Docker oficiais da Microsoft para obter o melhor desempenho.

Quais sistemas operacionais são os melhores para executar o IronOCR no Docker?

Para executar o IronOCR no Docker, recomenda-se o uso das distribuições Linux de 64 bits mais recentes, como Ubuntu 20, Ubuntu 18, Debian 11 e Debian 10, pois elas oferecem configuração e suporte fáceis.

Como configuro o IronOCR em contêineres Docker do Azure?

Para configurar o IronOCR em contêineres Docker do Azure, siga os mesmos passos que para outros ambientes Docker. Utilize o pacote NuGet do IronOCR, configure as distribuições Linux recomendadas e certifique-se de que todas as dependências necessárias estejam incluídas no seu Dockerfile.

Quais são os passos para configurar o IronOCR usando .NET 5 no Docker?

Para configurar o IronOCR usando o .NET 5 no Docker, você precisa criar um Dockerfile que instale o pacote NuGet do IronOcr, adicione pacotes necessários como apt-utils e libgdiplus e use as imagens oficiais do Docker do .NET 5 da Microsoft como imagem base.

O IronOCR pode ser usado em ambientes Docker no Windows?

Sim, o IronOCR pode ser usado em ambientes Docker no Windows. O processo envolve o uso do pacote NuGet IronOcr e a configuração do Dockerfile para incluir as dependências e configurações necessárias específicas para sistemas operacionais Windows.

Quais são os benefícios de usar o Docker para hospedar aplicativos OCR .NET?

Utilizar o Docker para hospedar aplicações OCR .NET permite uma implantação fácil, melhor gerenciamento de recursos e maior portabilidade em diferentes ambientes. Os contêineres Docker são autossuficientes, garantindo que as aplicações sejam executadas de forma consistente, independentemente de onde estejam implantadas.

É necessário configurar manualmente distribuições Linux não recomendadas no Docker?

Sim, se você estiver usando distribuições Linux diferentes das recomendadas (Ubuntu 20, Ubuntu 18, Debian 11, Debian 10), talvez precise realizar configurações manuais usando apt-get . Instruções para configuração manual estão disponíveis no guia "Configuração Manual do Linux" fornecido pela IronOCR.

Can I use IronOCR with Azure Docker Containers?

Yes, IronOCR is fully compatible with Azure Docker Containers, allowing you to deploy and run .NET OCR applications on both Linux and Windows platforms within the Azure ecosystem.

What is the best way to develop and debug Docker applications using IronOCR?

For those new to Docker with .NET, the documentation recommends resources from Microsoft on setting up Docker debugging and integration with Visual Studio projects. This approach facilitates a smoother development experience.

Are there any official Docker images recommended for IronOCR?

IronOCR recommends using Microsoft's Official Docker Images for running .NET applications. These images are designed to provide a high level of compatibility and performance for .NET-based applications.
