Setting up Express Backend API to use Docker

To set up a Dockerfile for your Clarek CRM backend using Express.js with port 8000, follow the steps below:

1. Create a Dockerfile:

Create a file named Dockerfile in the root directory of your Clarek CRM backend project.

# Use an official Node.js runtime as a base image
FROM node:20

# Set the working directory in the container
WORKDIR /usr/src/app

# Copy package.json and package-lock.json to the container
COPY package*.json ./

# Install app dependencies
RUN npm install

# Copy the rest of the application code to the container
COPY . .

# Expose port 8000
EXPOSE 8000

# Define the command to run your application
CMD ["node", "app.js"]

Noted that WORKDIR /usr/src/app becomes WORKDIR /clarek-crm-backend

1. Build the Docker Image:

Open a terminal and navigate to the directory containing your Dockerfile and application code. Run the following command to build the Docker image:

docker build -t clarek-crm-backend .

This command will build the Docker image using the instructions in the Dockerfile and tag it with the name clarek-crm-backend.

1. Run the Docker Container:

After building the image, you can run the Docker container using the following command:

docker run -p 8000:8000 -d clarek-crm-backend

This command maps port 8000 on your host machine to port 8000 in the Docker container and runs the container in detached mode (-d).

Now, your Clarek CRM backend should be accessible at http://localhost:8000.

Note: Make sure your Express.js application is configured to listen on port 8000. You can set the port in your Express.js application code or through a configuration file.

Remember to replace any placeholder names or values with your actual project details. Adjust the Node.js version in the FROM statement based on your project's compatibility.
