DockerCon 2022 Workshop and Conference
In this Dockercon 2022 blog, I’ll share what I’ve learned during the workshop and conference. But first, let me explain what Docker is. Docker is an open-source platform for developers to Build and Deploy applications based on packaged virtual containers, which are not only small but also lightweight. No matter which machine your applications are running they run the same. Docker containers can deploy on any machine without issues.
What I learned in DockerCon 2022 Workshop and Conference:
In the Dockercon 2022 workshop and presentation, they have covered
- Getting Started with Docker
- Containers and VMs
The goals of containers and virtual machines are similar to isolating an application and its dependencies into a self-contained unit that can operate anywhere. The difference between Containers and Virtual machines is their architectural approach.
Virtual Machine:
A virtual machine (VM) is simply an emulation of a real computer that runs applications much like one. A “hypervisor” runs virtual machines on top of a physical system.
Containers:
A container, unlike a virtual machine (VM), provides operating-system-level virtualization by abstracting the “user space”. Also, Containers share the host system’s Kernel with other containers.
Docker Image
A Dockerfile is used to create the Docker image. Each Dockerfile instruction creates a new “layer” in the image, with layers representing a section of the image’s file system that either complements or replaces the layer below it.
Now that we know about what Docker containers and images are, let me tell you about one customer who is using Docker Enterprise.
Visa Inc
“In the keynote on Day 2 of DockerCon 2017, Visa shared how Docker EEn is empowering them on their mission to make global economies safer by digitizing currency and making electronic payments available to everyone, everywhere. With Docker EE, Visa can now provision in seconds rather than days and respond quickly to new threats by deploying patches across their entire environment at one time.”
According to Docker.com, with Docker Enterprise Edition, Visa Inc. gains speed and operational efficiency. Visa presented how Docker EEn is supporting them on their mission to make global economies safer by digitizing currency and making electronic payments available to everyone.
Thank you for your time, I hope you are now filled with the knowledge you need to learn about Dockercon 2022.
