When Docker builds our image via the docker build command, it reads these instructions, executes them, and creates a final image. We’ll build a Dockerfile to containerize our React.js frontend and Node.js backend.Ī Dockerfile is a plain-text file that contains instructions for assembling a Docker container image. Let’s create an empty Dockerfile in the root of our project repository. Each layer stores important changes stemming from your base image’s standard configuration. These components will each be useful later on.ĭocker uses a Dockerfile to create each image’s layers. This includes the Docker CLI, Docker Compose, and a user-friendly management UI. First, you’ll need to download Docker Desktop and complete the installation process. We’ll explore how to run this app within a Docker container using Docker Official Images.

This includes everything needed to ship a cross-platform, multi-architecture web application. Containerizing your Slack clone appĭocker helps you containerize your MERN Stack - letting you bundle together your complete Slack clone application, runtime, configuration, and OS-level dependencies. This guide will help you completely containerize your Slack clone app. This lets you quickly create microservices. You can set up a MERN stack with a single Docker Compose file. How can you make things easier? Docker simplifies and accelerates your workflows by letting you freely innovate with your choice of tools, application stacks, and deployment environments for each project. Completing a large project with many developers becomes difficult with MERN. React is merely a library and might not help prevent common coding errors during development. Second, React extensively uses third-party libraries that might lower developer productivity due to integration hurdles and unfamiliarity. Challenges with compatibility, third-party integrations, and steep learning curves are common for non-JavaScript developers.įirst, For the MERN stack to work, developers must run a Node version that’s compatible with each additional stack component. However, developers can encounter issues as their projects grow. The MERN stack gives developers the flexibility to build pages on their server as needed.
