'Workdir and dot at the end of directory path
I'm looking at this tutorial: https://docs.microsoft.com/en-us/learn/modules/implement-docker-multi-stage-builds/3-examine-multi-stage-dockerfiles
And this part confuses me:
FROM mcr.microsoft.com/dotnet/core/sdk:3.1 AS build
WORKDIR /src
COPY ["WebApplication1.csproj", ""]
RUN dotnet restore "./WebApplication1.csproj"
COPY . .
WORKDIR "/src/."
RUN dotnet build "WebApplication1.csproj" -c Release -o /app/build
Why would you use WORKDIR twice here? Aren't we already in the src?
Does the dot at the end (/src/.) has any additional meaning?
Solution 1:[1]
Adding twice WORKDIR is for clarity. As best practise adding WORKDIR with absolute path is recommended for readability and maintenance purpose.
Working directory can also be verify as below
docker run -it imageName pwd
replace imageName -with actual Image Name
pwd with cd (windows current directory command)
Link for Docker best practises, refer WORKDIR section.
