DevOps Mock Web Application

This is a web application created for our DevOps workshop. Its primary purpose is to demonstrate server automation.

How to Run the Application as a Node.js App

1. Clone the repository and navigate to its directory:

   $ git clone https://github.com/ilmossp/webapp-devops
   $ cd webapp-devops

2. Create a .env file:

   $ touch .env

3. Add the database connection URL to the .env file. Depending on your database choice, use one of the following examples:

   • For SQLite:

     # SQLite
     DB_CONNECTION_STRING="sqlite:/path/to/file.db"

   • For PostgreSQL:

     # PostgreSQL
     DB_CONNECTION_STRING="postgres://user:[email protected]:5432/dbname"

4. Install the required dependencies:

   npm install

5. Start the application:

   node app.js

6. The application should now be listening on port 3000.

7. On your first run, make sure to send a request to the API route /sync in order to create the necessary database tables.

How to Run the Application from a Docker Image

Assuming you have cloned the project and are running it from the project directory:

1. Build the Docker image:

   docker build -t webapp .

2. Run the Docker container, mapping port 4000 on your host machine to port 3000 in the container, and provide the DB_CONNECTION_STRING as an environment variable (replace YOURCONNECTIONSTRING with your actual database connection string):

   docker run -p 4000:3000 -e DB_CONNECTION_STRING=YOURCONNECTIONSTRING webapp
