Docker Volume Example

Description

This repository provides an example of using Docker volumes with a Node.js application. It demonstrates how to use Docker volumes to persist data and share files between a host and a Docker container, which is useful for developers looking to manage data in a containerized environment.

Requirements

• Node.js
• Docker
• Yarn or npm for package management

Mode of Use

1. Clone the repository:

   git clone https://github.com/ferrerallan/docker-volume-example.git

2. Navigate to the project directory:

   cd docker-volume-example

3. Ensure you have Docker installed on your machine.
4. Build the Docker image:

   docker build -t docker-volume-example .

5. Run the Docker container with a volume:

   docker run -d -p 3000:3000 -v /host/path:/container/path docker-volume-example

Implementation Details

• Dockerfile: Contains instructions for building the Docker image.
• src/: Contains the Node.js application source code.

Example of Use

Here is an example of a simple Dockerfile for a Node.js application that uses volumes:

# Use the official Node.js image as a base
FROM node:14

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

# Copy package.json and package-lock.json files
COPY package*.json ./

# Install dependencies
RUN npm install

# Copy the rest of the application code
COPY . .

# Expose the application port
EXPOSE 3000

# Command to run the application
CMD ["node", "app.js"]

This Dockerfile sets up a Node.js application environment, installs dependencies, and runs the application. Docker volumes can be used to persist data and share files between the host and container.
