如何在docker中运行Aspose.Cells.GridWeb

Docker指南

先决条件

确保您的计算机上已安装Docker。您可以从官方Docker网站下载并安装Docker。

步骤1:创建一个Dockerfile

在项目目录中创建名为Dockerfile的文件。 Dockerfile应包含有关如何构建Docker镜像的说明。

步骤2:为GridWeb编写Dockerfile

这是一个带有ASP.NET Core应用程序的GridWeb演示的样本Dockerfile

# Use the official .NET6.0 runtime as a parent image
FROM mcr.microsoft.com/dotnet/aspnet:6.0-focal AS base
WORKDIR /app  
EXPOSE 80 


# Use the official .NET6.0 SDK as build enviroment
FROM mcr.microsoft.com/dotnet/sdk:6.0-focal AS build

WORKDIR /src  
#we shall use .net6.0 project
COPY ["GridWeb.Demo.NET6.0.csproj", "."]
RUN dotnet restore "./GridWeb.Demo.NET6.0.csproj"

# Copy everything else and build
COPY . .
WORKDIR "/src/."
RUN dotnet build "GridWeb.Demo.NET6.0.csproj" -c Release -o /app/build

# Publish the app
FROM build AS publish
RUN dotnet publish "GridWeb.Demo.NET6.0.csproj" -c Release -o /app/publish

# Final stage/image
FROM base AS final
WORKDIR /app
# if you want display better like in windows ,you need to install kinds of fonts in /usr/share/fonts/ 
# then the application can parse and render the fonts which is used in the spread sheet file
# here we don't provide extra fonts resource
# Install Fonts because the SDK image contains very few fonts. The command copies font files from local to docker image. Make sure you have a local “fonts” directory that contains all the fonts you need to install. In this example, the local “fonts” directory is put in the same directory as the Dockerfile.
# COPY fonts/* /usr/share/fonts/
# the basic file path which contains the spread sheet files 
RUN mkdir -p /app/wb
# the cache file path for GridWeb
RUN mkdir -p /app/filecache
# the cache picture path for GridWeb
RUN mkdir -p /app/piccache
COPY wwwroot/wb/*.xlsx /app/wb/

COPY --from=publish /app/publish .

# set the start command for the docker image 
ENTRYPOINT ["dotnet", "GridWeb.Demo.NET6.0.dll"]

步骤3:构建Docker镜像

构建Docker镜像:从终端执行以下命令来构建Docker镜像:

docker build -t gridweb-demo-net6 .

您可以将gridweb-demo-net6替换为您想要给Docker镜像命名的名称。

步骤4:运行Docker容器

构建镜像后,您可以使用以下命令来运行一个容器:

docker run -d -p 24262:80 --name gridweb-demo-container  gridweb-demo-net6

Docker运行命令选项的说明 -d:在分离模式下运行容器(在后台)。 -p 24262:80: 将容器中的端口 80 映射到主机上的端口 24262。 –name gridweb-demo-container: 为容器分配一个名称。

步骤5:验证容器是否正在运行

要检查容器是否正在运行,请使用以下命令:

docker ps

这将列出所有正在运行的容器。你应该能看到你的容器以及它的名称和状态。

步骤 6: 访问Web应用程序

打开网页浏览器,输入 http://localhost:24262/。您应该可以看到您的应用程序正在运行。

您将看到GridWeb的通用开发指南。

在页面中点击demo,您可以对电子表格文件进行编辑操作。

额外命令

停止容器

要停止运行的容器,使用以下命令:

docker stop gridweb-demo-container

删除容器

要删除一个停止的容器,使用以下命令:

docker rm  gridweb-demo-container

删除图像

要删除图像,请使用以下命令:

docker rmi gridweb-demo-net6
