Docker-Volume
Docker allows you to create something called volumes. Volumes are like separate storage areas that can be accessed by containers. They allow you to store data, like a database, outside the container, so it doesn't get deleted when the container is deleted. You can also mount from the same volume and create more containers having the same data.
Docker Network
Docker allows you to create virtual spaces called networks, where you can connect multiple containers (small packages that hold all the necessary files for a specific application to run) together. This way, the containers can communicate with each other and with the host machine (the computer on which the Docker is installed). When we run a container, it has its own storage space that is only accessible by that specific container. If we want to share that storage space with other containers, we can't do that.
Task-1
- Create a multi-container docker-compose file that will bring UP and bring DOWN containers in a single shot ( Example - Create application and database container )
Task-2
- Learn how to use Docker Volumes and Named Volumes to share files and directories between multiple containers.
Create two or more containers that read and write data to the same volume using the
docker run --mountcommand.
- Verify that the data is the same in all containers by using the docker exec command to run commands inside each container.
Use the docker volume ls command to list all volumes and the docker volume rm command to remove the volume when you're done.
Finally!! 🎉
I have completed✅ the Docker hands-on and I hope you have learned something interesting from it.🙌
Thank you
