# Docker Mastery
This project is intented to use with exercises for Docker Mastery course by tdevs.in.
## Environment Variables
This project uses below environment variables:
```shell
DB_URL #Example: jdbc:mysql://localhost:3306/dockermastery Syntax: jdbc:mysql://:/
DB_USERNAME # Username of databases Example: root
DB_PASSWORD # Password of database Example: root12345
```
Make sure your DB is up and running and an empty database is created.
For example, if you have a mysql instance running locally at port 3306, connect to it and create a new database schema using below command:
```sql
CREATE DATABASE dockermastery;
```
The DB URL will become `jdbc:mysql://localhost:3306/dockermastery`
## Build Steps
This project uses JAVA 21 and Maven. Make sure you have that installed in the system.
This project has an inbuilt Maven wrapper `mvnw` that can be used to build, test, and run the project.
To Run this project, below command can be used:
```shell
./mvnw spring-boot:run
```
or
```shell
mvn spring-boot:run
```
The Run will fail if above environment variables are not set.
You can pass these environment variables as below:
On linux/macOs
```shell
export DB_URL="jdbc:mysql://localhost:3306/dockermastery"
export DB_USERNAME=root
export DB_PASSWORD=root
```
On Windows:
```batch
set DB_URL=jdbc:mysql://localhost:3306/dockermastery
set DB_USERNAME=root
set DB_PASSWORD=root
```
As the application starts, it creates a table called `todo` and add a few rows to it.
The application runs at port `8080`
Once the application is started, you can go to your browser and go to url `http://localhost:8080/`. This will return the following response on your browser:
```json
{
"todos": [
{
"id": 1,
"title": "Finish Assignment",
"description": "Complete the assignment on database management systems.",
"status": "pending"
},
{
"id": 2,
"title": "Grocery Shopping",
"description": "Buy milk, eggs, and bread from the supermarket.",
"status": "completed"
}
]
}
```
If you are getting this output, your application is running correctly.
