Azure Pipeline to build docker images fails using same docker file in Visual Studio

I’m trying to create a deployment pipeline to deploy my image to Kubernetes cluster. The first step in this process is to create an image based on the docker file. The docker file I’m using was generated from Visual Studio when I added docker support and successfully creates the image when right clicking on the docker image and selecting to create it. When I configure the Azure Pipeline, the create docker image fails as soon as it tries to build the actual solution. The previous step grabs all the sources files but then fails on the docker image creation with

[error]COPY failed: stat
no such file or directory [error]/usr/bin/docker failed with return
code: 1

The following is the docker file generated from Visual studio and is referenced by the azure pipeline stage to create the docker image.

FROM AS base

/src COPY [“DockerTest/DockerTest.csproj”, “DockerTest/”] RUN dotnet
restore “DockerTest/DockerTest.csproj” COPY . . WORKDIR
“/src/DockerTest” RUN dotnet build “DockerTest.csproj” -c Release -o

FROM build AS publish RUN dotnet publish “DockerTest.csproj” -c
Release -o /app

FROM base AS final WORKDIR /app COPY –from=publish /app . ENTRYPOINT
[“dotnet”, “DockerTest.dll”]
