I have a jenkins container and a pipeline which consist of building docker images. I have mounted the necessary mounts (/var/run/docker.sock, /var/run) for jenkins to use docker commands. I also bind mounted a folder from my host to jenkins as its workspace directory (/var/jenkins_home/workspace).

Here is the Dockerfile which is part of my project:

FROM microsoft/dotnet:2.1-aspnetcore-runtime AS base
 WORKDIR /app
 EXPOSE 80

 FROM microsoft/dotnet:2.1-sdk AS build
 WORKDIR /src
 RUN hostname && pwd
 COPY /storage/admin/jenkins/workspace/tremplinx_master-NAUVRHOZ5IJBBHVQ54PTEZJJL33WO7NMFUYS5BF3C5H3LBCDC3XA/SPA/SPA.csproj SPA/SPA.csproj
 RUN dotnet restore SPA/SPA.csproj
 COPY . .
 WORKDIR /src/SPA
 RUN dotnet build SPA.csproj -c Release -o /app

Running my pipeline fail with the following error:

[tremplinx_master-NAUVRHOZ5IJBBHVQ54PTEZJJL33WO7NMFUYS5BF3C5H3LBCDC3XA] Running shell script

+ docker build -t spa:dev-0.0.1 SPA/

Sending build context to Docker daemon  4.536MB

script returned exit code 1

I can't figure out why docker is using /var/lib/docker/tmp/docker-builder969545350... folder whereas I have specified the full path containing my project. I'm new to Jenkins so forgive me if I forgot to specify important information .

Thank you.

I've solved my issue. I had to change the way I call my Dockerfile and changing the WORKDIR inside.
