You will then build a container using that image and push it to Docker Hub for future use. In this tutorial, you will create an application image for a static website that uses the Express framework and Bootstrap. Using an image ensures that the environment in your container is standardized and contains only what is necessary to build and run your application. The image includes your application code, libraries, configuration files, environment variables, and runtime. When building and scaling an application with Docker, the starting point is typically creating an image for your application, which you can then run in a container. Though containers are not new, they offer benefits - including process isolation and environment standardization - that are growing in importance as more developers use distributed application architectures. A container is an isolated process that runs on a shared operating system, offering a lighter weight alternative to virtual machines. The first step is to open the file index.js and import the packages.The Docker platform allows developers to package and run applications as containers. Thus, you are ready to build the application! For instance, you would not want someone to add a SQL query instead of email address because it could create issues. Lastly, you need the package express-validator to sanitize user input.

You will also use the express package to create two endpoints: You will use the mysql package to manipulate your database.

#NODE JS DOCKER FILE BUDDY INSTALL#

Install them with the following command: npm install mysql dotenv express express- validator The dependencies you need for this project are mysql, express, express-validator and dotenv. The above command initializes your project and it auto-completes the package.json file with the default values. You can initialize the project with the following command: npm init -y The next step is to initialize your Node.js project and install the required dependencies. Initialize the project and install dependencies Also, you are ready to use MySQL in your Node.js application. Now you can run MySQL commands and play around with the database.

#NODE JS DOCKER FILE BUDDY PASSWORD#

Enter the same password you mentioned in the first command above. You will be prompted to enter the password. If you want to run the container bash and play directly with MySQL, run the following command: docker container exec -it nodejs-mysql bashĪfter that, start the MySQL monitor as follows: mysql -u root -p Now you can access your database from the terminal and from your application.

Lastly, it creates a new database called emails_db.

It starts the MySQL database on port 3306.

It pulls the image mysql:5.7 from DockerHub and then runs it.

The above command does the following things:

To avoid inconsistencies and installing new stuff on your machine, you will use the official Docker image for MySQL.īefore going further, run the following command in your terminal: docker run -p 3306: 3306 -name nodejs-mysql -e MYSQL_ROOT_PASSWORD=pass -e MYSQL_DATABASE=emails_db -d mysql: 5. Thus, you can create all the files and folders as follows: take nodejs-mysql touch index.

a file with the server/database configuration.

The first step is to create the project structure. I am not responsible for misusing the API, for using it maliciously or for any other use. Note: If you decide to use the API or an improved version to collect email addresses, make sure you comply with all the relevant regulations.

The technologies used in this tutorial are as follows: You will build a simple application that allows you to collect email addresses from people.
