   docker run -p 8080:8080 employee
   --> run docker in the background
   docker run -d -p 8080:8080 employee-api
   
   

3. Access the H2 console to verify the database setup:
   Open your web browser and go to http://localhost:8080/h2-console.
   Use the following details to log in:
   a. JDBC URL: jdbc:h2:mem:testdb
   b. Username: sa
   c. Password: password

   Use tools like Postman or Curl to test the API endpoints:
   

GET all employees: GET http://localhost:8080/api/employees
GET an employee by ID: GET http://localhost:8080/api/employees/{id}
POST a new employee: POST http://localhost:8080/api/employees
PUT update an employee: PUT http://localhost:8080/api/employees/{id}
DELETE an employee: DELETE http://localhost:8080/api/employees/{id}

5. Verifying the Container is Running
   A. List Running Containers:
   You can list all running containers using:
   docker ps
   This will show you all the containers that are currently running, including the employee-api container.
   
   

B. Check Logs:

To check the logs of the running container (replace <container_id> with the actual container ID from the docker ps output):

docker logs <container_id>

C. Stopping the Container
If you need to stop the container, you can do so with:

docker stop <container_id>

D. To remove the container after stopping it, use:

docker rm <container_id>

7. Access the swagger ui
   http://localhost:8080/swagger-ui/index.html
