Hello Dev friends! 👋
Welcome to the series of Beginner to Expert guide on Docker 🐋 & Kubernetes ☸️ 🚀
From our previous blog, I hope you got the idea of how Docker comes in the present.
If you haven't read it, I recommend you to read it before you jump into this article; it will ease your Docker journey.
Now, from this article, we will truly dive into Docker tutorials, not actually from this article, but from the next article 😁, in this article, we will know the terminologies involved in Docker (which is important) for a better understanding of the whole Docker article series.
Containerization 🛡️
Containerization is a modern technology that allows us to bind the whole binaries/libraries and source code into a single pot to run into any infrastructure.
For a practical example, we can say that we can deploy a node.js backend API into AWS EC2 infrastructure.
Here combining the node.js code and packages into a single container is called containerization.
Docker 🐳
People usually interchange the terms Docker and containerization, but both have different perspectives and use cases. While containerization is a technique, Docker is the popular toolkit to container an application.
Docker helps us to containerize the application and use this Docker container to deploy in any infrastructure efficiently.
Images 🖼️
I guess, you may often come across the term **docker image**, yes that is the image. Basically, an image is a file containing the information to build a container.
We usually start with a base image and modify it according to our project needs.
Container 🚢
A container is a lightweight portable instance of an image, which is usually deployed in any infrastructure to run any application.
Ports 🌐
Containers are usually deployed on a remote server and to communicate with that container, we need to define the port. So, a port is the container gateway that helps us to talk and use the deployed containerized application. 🚪
Volumes 💽
Volumes refer to the amount of disk storage allocated to the container during deployment. This volume helps us to run the application efficiently. Wisely calculating volume is crucial for efficient resource management.
Registry 📦
Registry refers to the store of different container images. It allows us to store our container images with versions. It stores each image with a unique name.
Docker hub is a popular Docker container registry to store Docker container images.
I guess these are enough for now to know; from the next post, we will jump into installation and then start with the main concepts of Docker and Kubernetes.
Till then see you Bye Bye! 👋
