Docker 退出，状态码为 139

问题描述

我有一个 .Net Core 应用程序，它可以在 docker 镜像上运行什么.我在命令行中输入:

I have a .Net Core application what it to run on a docker image. I typed in the command line :

docker run -d --net=bridge -it --name=testapp -v /var/test/:/var/test microsoft/aspnetcore-build /bin/bash -c "dotnet /var/test/test.dll"

它已创建，但以状态代码 139 退出.可能是什么问题.

it is created but it is exiting with a status code 139. What could be the problem.

推荐答案

与其同时运行 docker 镜像和运行 bash 命令 (-c "dotnet/var/test/test.dll")，划分它的步骤.

Instead of running the docker image and running the bash command (-c "dotnet /var/test/test.dll") at the same time, divide it to steps.

例如:

1. 运行这个命令:

1. run this command:

docker run -d --net=bridge -it --name=testapp -v /var/test/:/var/test microsoft/aspnetcore-build

它将运行一个名为 testapp 的 aspnetcore 映像，并在您的机器和 docker 机器之间映射测试文件.

it will run an aspnetcore Image named testapp and map the test file between the your machine and the docker machine.

进入docker机器:

enter the docker machine:

 docker exec -it testapp bash

进入/var/test 文件夹并运行应用程序:

enter the /var/test folder and run the app:

 dotnet test.dll
