True FROM microsoft/aspnetcore:latest This command specifies the base image for your container. WORKDIR /apps/ContosoApp This command sets the working directory for the container. COPY ./ . This command copies all files and folders from the current directory (where the Dockerfile resides) to the working directory (/apps/ContosoApp) inside the container. RUN powershell ./setupScript.ps1 This command runs the setupScript.ps1 script using PowerShell within the container during the build process. CMD ["dotnet", "ContosoApp.dll"] This command defines the default command that will be executed when the container starts.

You are correct. This has been discussed in Udemy course as well as follows, The first statement in the Dockefile must be the FROM statement to specify the image to use as the base image. Then specify the Image working directory Then copy all of the application contents using the COPY command And then use the CMD command to run the PowerShell command and the ENTRYPOINT statement to run the dotnet application.

as per Udemy, the last steps would be CMD powershell ./script.ps1 and then ENTRYPOINT (dotnet, xx.dll) which I believe is the correct answer. But unfortunately the options are not there in Examtopic

ENTRYPOINT instruction works very similarly to CMD in that it is used to specify the command executed when the container is started.

This is correct answer It should be: - FROM - WORKDIR - COPY - RUN - CMD because WORKDIR will create directory if it doesn't exist https://docs.docker.com/engine/reference/builder/#workdir

Here are the five commands you can use in the Dockerfile: FROM: Specify the base image. Dockerfile Copy code FROM mcr.microsoft.com/dotnet/core/aspnet:3.1 COPY: Copy the application files to the container. Dockerfile Copy code COPY . /app WORKDIR: Set the working directory to the application folder. Dockerfile Copy code WORKDIR /app RUN: Execute the setup script during the image build process. Dockerfile Copy code RUN ./setupScript.ps1 CMD: Specify the command to run when the container starts. Dockerfile Copy code CMD ["dotnet", "ContosoApp.dll"] Make sure to adjust the paths and filenames according to your actual file structure.
