We use the Azure DevOps build pipelines. In one pipeline we now want to add a build-step to build a container-image with something like Docker@2 or similar. As a preparation for this we have also added a previous DockerInstaller@0-step so that docker is available.
Problem: When we run the pipeline on our build-server we get the error error during connect: Post http://%2F%2F.%2Fpipe%2Fdocker_engine/v1.32/images/create?fromImage=mcr.microsoft.com%2Fdotnet%2Faspnet&tag=7.0: open //./pipe/docker_engine: The system cannot find the file specified. In the default daemon configuration on Windows, the docker client must be run elevated to connect. This error may also indicate that the docker daemon is not running. . This may be true because we did not install a docker daemon on the build-server. However, we do not want to install anything on the build-server. We just want to rely that the DockerInstaller@0-step makes the docker available on the fly in a working way.
Is that possible without installing anything "globally" on the build-server as preparation?
Notes:
- On the build-server we just want to do
docker build ...and we do not want to run any container with something likedocker run .... - In the
...\_work\_tool\docker-stable\17.9.0-ce\x64-folder from the pipeline-task on the build-server there is just a 19mbdocker.exe-file without anything else. When runningdocker.exe pull mcr.microsoft.com/dotnet/aspnet:7.0in this folder in an elevated cmd we get the same error-message.
