+#DOCKER-COMPOSE-NODEJS-EXPRESS-MYSQL
+In this sample, we will look at the functionality provided by 'Docker Compose' for defining and running multi-container Docker applications.
+
+We are going to use 'MySQL' like our specialized database and 'Node.js' as our platform for creating highly performant web applications.
+
+#NodeJS v14.17
+#MySQL 5.7

+</p>
+
+### To Build both of images 
+'docker-compose build'
+
+### RUN THE PROJECT
+`docker-compose up`
+
+### INSPECT YOUR MYSQL CONTAINER(to see your database)
+1. docker ps
+2. docker exec -it YOUR_MYSQL_CONTAINER_ID bash
+3. mysql -u root -p
+4. put the password(123)
+5. enter 
+6. use CHIRINOS;
+7. show tables;
+8. describe EMPLOYEE;
+
+
+ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '123';
