This Edureka video on Containerization will help you understand how to create a containers with examples.
Docker is an open platform that allows use package, develop, run, and ship software applications in different environments using containers.
In this course We will learn How to Write Dockerfiles, Working with the Docker Toolbox, How to Work with the Docker Machine, How to Use Docker Compose to fire up multiple containers, How to Work with Docker Kinematic, Push images to Docker Hub, Pull images from a Docker Registery, Push stacks of servers to Docker Hub.
How to install Docker on Mac.

Following the second video about Docker basics, in this video, I explain Docker architecture and explain the different building blocks of the docker engine; docker client, API, Docker Daemon. I also explain what a docker registry is and I finish the video with a demo explaining and illustrating how to use Docker hub
In this video lesson you will learn:
#docker #docker hub #docker host #docker engine #docker architecture #api
Now since we have understood the basic architecture of Docker in my previous tutorial titled “Docker: Understanding Docker Architecture and Components”, lets now learn how to install Docker and run some basic commands.
3. The memory should be at least 2 GB and there should be at least 2 core CPU.
The First thing we are going to do is to run the **“docker run hello-world” **command.
This command tries to find the “hello-world” image locally and if not found, it then downloads an image from the docker hub and runs the container out of this image.

If you are a developer who uses Docker, odds are you may have heard that you can use volumes to maintain persistent state for your containers in production. But what many developers don’t realize is that volumes can also be an excellent tool for speeding up your development workflow.
In this post, I’ll give you a brief overview of what is a Docker volume, how docker host volumes work, and show you a tutorial and example of how you can use volumes and nodemon to make coding with Docker easier and faster.

By Design, Docker containers don’t hold persistent data. Any data you write inside the docker’s writable layer is no longer available once the container is stopped. It can be difficult to get the data out of the container if another process needs it.
Also, a container’s writable layer is tightly coupled to the host machine where the container is running. You can’t easily move the data somewhere else.
Docker has two options for containers to store files in the host machine, so that the files are persisted even after the container stops: volumes, and bind mounts.
/var/lib/docker/volumes/on Linux). Non-Docker processes should not modify this part of the filesystem. Volumes are the best way to persist data in Docker.
Let’s understand them in detail one by one.
