Dear Docker Community:
In a Docker definition (Dockerfile), I have generally focus on containerizing my application, which includes specifying how the application environment should be set up and what should be included in the container. The MVC (Model-View-Controller) structure is a design pattern for organizing the code within your Node.js application, and it primarily relates to the code and application structure inside the container, not the Dockerfile itself. However, each time I have run the Docker command then I have typed in the localhost:8080 then I will receive an error message that stated “CANNOT GET”.
Here is an example of my Dockerfile Definition:
Use an appropriate Node.js base image
FROM node:18-alpine
Set the working directory in the container
WORKDIR /ivoteballot
COPY controllers /ivoteballot/
COPY models /ivoteballot/
Copy the rest of your application files to the container
COPY . .
Copy package.json and package-lock.json to the container
COPY package.json /ivoteballot/
COPY package-lock.json /ivoteballot/
Install dependencies
RUN npm install
EXPOSE 8080
Define the command to start your Node.js application
CMD [“node”, “index.js”]
Here is my docker command lines:
