Docker Container Setup - Documentation

This is the documentation on how to containerize and run the Recodehive website while using Docker.

Prerequesites

  • Docker installed
  • Docker compose installed (Optional)

Steps

1. Create a Dockerfile in the root directory

This is a text document that contains all the commands needs to build a Docker image. Basically a blue print of a docker image.

Key instructions include

  • FROM <base_image>:<tag> : The first instruction and specifies the base image to build upon.
  • WORKDIR <path> : Sets the working directory inside the container for subsequent instructions.
  • COPY <source> <destination> : This instruction copies files or directories from your local machine (the build context) into the Docker image.
  • RUN <command> : Executes commands during the image build process. This is used for installing dependencies, updating packages etc.
  • EXPOSE <port> : Informs docker that the container listens on the specified ports at runtime.

2. Build the Docker Image

docker build -t recodehive-app .

This command builds the Docker image using the instructions in the Dockerfile and tags it as recodehive-app.

3. Run the Container

docker run -p 3000:3000 recodehive-app

This runs the container and maps port 3000 from the container to your local machine.
Now Visit http://localhost:3000 to view the site.
