What is Docker? Docker is a containerized virtual environment that makes it easy to develop, maintain, and deploy apps and services. Get a quick run down in under 10 minutes about Docker.

We'll bring you through virtual machines, images, and containers

This "Introduction To Docker and Docker Containers" course is at EXACTLY the correct level. it sets up the context very well.

[Shane-Singleton]

Docker basically is virtualization. But the genius is that it cuts out all the guest OS overhead and just virtualizes an app package directly on, yet segregated from, the actual host OS. This saves a TON of disk space, and quite a bit of ram and cpu resources as well.

Best simple Docker explanation I have found on YouTube. You have the When, Why and How summary. Great job!👍

[mrmiked]

What you've outlined is a Type 2 Hypervisor, such as Hyper-V, where the virtualization environment is built into the OS (Infrastructure - OS - Hypervisor - VMs - APPS), whereas a Type 1 hypervisor, like VMware ESX, takes over the whole server and allocates space directly to VMs (Infrastructure - Hypervisor - VMs - Apps). Docker is still a better way to go for hardcore development and app deployment, though. Excellent video....I learned quiet a bit about Docker!

[MrCoffis]

Best video explaining what docker is period.

[michaelpeters]

This is the best explanation of what docker is anywhere on the internet. Thank you!

[shtaket]

I just love that drawing style of yours and how you present the information, huge thanks, and peace!

[mrmertozturk]

Best explanation of the platform I've seen so far, amazing!

[rimantasmalevanovas]

I was looking for explanation video to introduce my friend to containerisation. This. Is. PERFECT.

[vikranthaldavnekar]

You are the boss man, such a simple yet a very clear explanation!!. Did not find it elsewhere. Thanks a lot.

[sairamsubu]

Just Wow..!! Very clearly and nicely explained.

[sachinkarve]

You truly are a "SIMPLE" engineer. best explanation so far

[yoericktv]

This was such a good video.
I learned that docker is like virtualization 2.0
and it kicks butt

[renovatiovr]

It has to be said that in case of virtualization, quite often there is no OS sitting on the infrastructure, but rather the hypervisor behaves as the base

[aayeshazia]

Great introductory video about Docker :)

[MuhammadKhan-ylmt]

WoW, how tremendously you have explained it (without the chunky fat marketing jargon). I'm so impressed and subscribed.
Oh, thank you.

[zeroice]

As Casey Doe pointed out below, you have the diagram showing the Hypervisor upside down if you are referring to VMware (Type 1). It will be accurate if you are referring to Hyper-V though (Type 2)

In VMware, Infrastructure/Servers/Hosts -> Hypervisor -> VMs -> Guest OS installed on the VMs.

Otherwise, great video on the topic.

[MrVimalraina]

explained in a very simple way with enough details to get started, thanks for your effort!!
