Question 6

You are developing an ASP.NET Core MVC API microservice that calculates and provides loan rates. The microservice is configured to listen on port 6000.
The microservice must be deployed to a Docker container in Windows. You add a file named Dockerfile to the microservice project.
You need to build the Docker image.
In which order should you perform the actions? To answer, move all actions from the list of actions to the answer area and arrange them in the correct order.

Correct Answer:

1 - Use the FROM instruction to define the base image.
2 - Use the WORKDIR instruction to define the working directory.
3 - Use the COPY instruction to copy the source code into the image and then use the RUN instruction to restore NuGet packages.
4 - Use the ENTRYPOINT instruction to use the container as an executable.
5 - Use the EXPOSE instruction to specify the listen port and build and run the application.
Explanation:
Step 1: Use the FROM instruction to define the base image.
FROM creates a layer from the ubuntu Docker image.
The first FROM command is an important Docker command, allowing you to pull dependencies from other images.
Step 2: Use the WORKDIR instruction to define the working directory
The WORKDIR instruction sets the working directory for any RUN, CMD, ENTRYPOINT, COPY and ADD instructions that follow it in the Dockerfile.
Step 3: Use the COPY instructions to copy the source code into the image and then use the RUN instruction to restore NuGet packages.
Step 4: Use the ENTRYPOINT instruction to use the container as an executable Step 5: Use the EXPOSE instruction to specify the listen port and build and run the application.
