All about docker volumes and Docker Networking

Docker volume is a special container for storing important data.
It keeps data safe even if other containers are restarted or removed.
Think of it as a storage box that can be shared between different containers and your computer.
It's like having a secure place to keep files and databases when using Docker.
Docker volumes ensure data availability and easy movement, which is helpful for various applications and businesses.

Docker networking is like connecting different virtual containers together.
It allows these containers to communicate and share information.
It's like building a bridge between isolated containers, enabling them to work together.
This networking capability lets applications in containers talk to each other and the outside world.
It's similar to how your computer connects to the internet and interacts with other devices.

Create a multi-container docker-compose file which will bring UP and bring DOWN containers in a single shot (Example - Create application and database container)

step 1: clone the repo and check whether it is cloned or not.

step 2: Now go to the directory and perform ls command:

step 3: Check the docker file

step 4: check the running container using docker ps

see there are no running containers now.

step 5: Use the docker-compose up command to start a multi-container application and docker-compose scale command to increase or decrease the number of replicas for a specific service.

step 6: let's check your browser

step 7: Use the docker-compose ps command to view the status of all containers, and docker-compose logs to view the logs of a specific service.

step 8: Use the docker-compose down command to stop and remove all containers, networks, and volumes associated with the application

For another Docker concepts.
