centos 7的Docker设置
提问于 2018-12-13 03:11:03
你好，我是新手，正在尝试在centos 7环境中设置docker。我已经使用https://docs.docker.com/install/linux/docker-ce/centos/安装了docker，然后尝试使用此https://docs.docker.com/engine/examples/dotnetcore/#build-and-run-the-docker-image运行站点。我曾尝试在locahost上执行wget，并在这些端口上执行docker ip，但都无济于事。
这是我执行的代码：
docker build -t aspnetapp .
docker run -it -d --name myapp aspnetapp这是docker文件
FROM microsoft/dotnet:2.1-aspnetcore-runtime AS base
WORKDIR /app
EXPOSE 64928
EXPOSE 44340
FROM microsoft/dotnet:2.1-sdk AS build
COPY . /app
WORKDIR /app
RUN dotnet restore "TestDocker.csproj"
FROM build AS publish
RUN dotnet publish "TestDocker.csproj" -c Release -o /app
FROM base AS final
COPY --from=publish /app .
ENTRYPOINT ["dotnet", "TestDocker.dll"]这将完美地构建和运行
[root@local testSite]# docker ps

Docker容器有自己的网络堆栈。您需要将容器上的端口公开给外部世界，并将这些端口映射到主机端口。您可以使用"-p“标志来完成此操作。
