I have an .net core application where I would like to make a SonarBuild inside a container.
So I have a Dockerfile like this:
FROM microsoft/aspnetco
As I have read in this thread: https://github.com/dotnet/dotnet-docker/issues/520, we can run a dotnet tool global command inside a container setting the following line:
ENV PATH="${PATH}:/root/.dotnet/tools"
So my final Dockerfile is like:
FROM microsoft/dotnet:2.1-sdk as build-env
WORKDIR /src
COPY question-metrics-api/question-metrics-api.csproj question-metrics-api/
COPY question-metrics-data/question-metrics-data.csproj question-metrics-data/
COPY question-metrics-domain/question-metrics-domain.csproj question-metrics-domain/
COPY tests/question-metrics-domain-tests/question-metrics-domain-tests.csproj tests/question-metrics-domain-tests/
RUN dotnet restore tests/question-metrics-domain-tests
RUN dotnet restore question-metrics-api/question-metrics-api.csproj
COPY . .
#Run tests
RUN dotnet test tests/question-metrics-domain-tests/question-metrics-domain-tests.csproj
#Begin Sonar
RUN dotnet tool install -g dotnet-sonarscanner
ENV PATH="${PATH}:/root/.dotnet/tools"
RUN dotnet sonarscanner begin /k:"question-metrics-api" /d:sonar.host.url="http://sonarqube:9000" /d:sonar.login="7ed84e09a17a31e783fa8522d876e27fe4624977"
RUN dotnet build
RUN dotnet sonarscanner end /d:sonar.login="7ed84e09a17a31e783fa8522d876e27fe4624977"
Hope that helps someone!
FROM microsoft/aspnetcore-build as build-env
That's the issue. Look at the dockerhub page for this: https://hub.docker.com/r/microsoft/aspnetcore-build/. See how it says that it only supports versions 1.1 and 2.0:
Latest images for 2.1 and newer are now available on microsoft/dotnet. See this link for more details about migrating to 2.1.
dotnet tool
is only available in 2.1 and later. That's why doing RUN dotnet tool install --global dotnet-sonarscanner
fails. dotnet
doesn't know about a dotnet tool
command at all. It tries to look for dotnet-tool
in your $PATH, as a fallback, but no such thing exists either.
You actual fix was:
FROM microsoft/dotnet:2.1-sdk as build-env
Because this uses the new 2.1 SDK, which does know of the dotnet tool
command.
