使用VSTS构建Linux C ++

Question

I'm trying to build a C++ app for Linux using VSTS. The build is defined by the Docker container template, and the Agent queue is Hosted Linux.

When running, I get [error]Unhandled: No Docker file matching /opt/vsts/work/1/s/**/Dockerfile was found.

How do I create the Docker file requested by the error message?

Answer 1

The error means that there isn't the Dockerfile file existing in working folder, you can include the Dockerfile file in the source control and map to the agent (Get sources of build definition)

There is the Docker image that shared by others, for example: madduci/docker-ubuntu-cpp and the CMake generated files will be in build folder, if you just need to build the C++ project, you can refer to these steps (CMakeLists.txt is in the root of the repository):

1. Add Docker task (Action: Run a Docker command ; Command: run -v $(Build.SourcesDirectory):/project madduci/docker-ubuntu-cpp )
2. Publish Build Artifacts (Path to publish: $(Build.SourcesDirectory)/build )

If you need to build the docker image, you need to create Dockerfile.

Answer 2

When the Docker task is set to Build an image you get an option to specify a Docker file:

**/Dockerfile means that the task will search your repository for a file named Dockerfile and use that to build the image.

The error you get means that this file can't be found. You can find some examples of Dockerfiles here in the Docker documentation . This blog describes how to build C++ applications that run on a Linux container
