In this file, you can specify the services that make up your application, including the web server, database, and any other dependencies.įor example, to create a Pern stack project with a PostgreSQL database, your docker-compose.yml the file might look something like this: version: '3.8' services: postgresql_server: image: postgres:12-alpine environment: POSTGRES_USER: your_pg_user POSTGRES_PASSWORD: your_pg_password POSTGRES_DB: your_pg_db ports: - "5432:5432" backend: container_name: backend build: context: your-backend-directory dockerfile: Dockerfile # same as of your docker file name environment: - ENV_NAME=value # your environtment varibles value volumes:. Create a docker-compose.yml file in your project directory:Ī docker-compose.yml the file is used to define and run multi-container Docker applications.# Start the server (development mode) CMD # Start the server (production mode) CMD īut if you want to run your pern stack project in docker using development mode your Dockerfile file might look something like this: FROM node:14-alpine # Install dependencies RUN npm install # Copy application code COPY. In your Dockerfile, you can specify the base image to use, install any necessary dependencies, and configure the environment for your application.įor example, to implement a Dockerfile in the Pern stack project, your Dockerfile might look something like this: FROM node:14-alpine # Install dependencies RUN npm install # Build the app RUN npm run build # Copy application code COPY. Create a Dockerfile in your project / package directory:Ī Dockerfile is a text file that contains the instructions for building a Docker image.Create a new directory for your project and navigate to it:.For example, on Ubuntu, you can use the following command: If you are using a Linux operating system, you can install Docker using the package manager of your distribution.If you are using a Windows or Mac operating system, you can download Docker Desktop from the following link:.Here is a step-by-step guide on how to dockerize your pern stack project:
