In the previous lecture I have shown you what is a client and basically it is separate executable file
located on your computer where you have Dockery installed and with help of a client you are able to
connect to a demon and send some commands to you.
For example you could say please start the container with a will to image or please at least two images
and so on.
Just sending commands to block our server and getting some output from it.
Now let me talk in the dailies about Dr Sara look our Sara is actually set of different processes and
docker demon is one of them.
Let me go back to timing though and the here last command that they have executed was Dr. Morrison and
I have shown you that when Dr Sara is stopped we will see such error cannot connect to book a demon.
No let me execute the same command once again because no Dr Sara is running again and here in this output
you'll see several blocks throws the block is information about engine here you see it's virus and it
actually matches.
In my case somewhere else none of the docker client.
Also next you see API of origin.
And basically this a version is important for communication with Docker client because a client communicates
with Docker etcetera by API.
Next you see goal line version because again Sara and client are written in goal landing and both set
from the client are available in GitHub repository.
And here you see the same last comment that was used for this repository at GitHub next you see built
date and underlined OIS architecture and here in this output you see Linux Linux and d 64 but Docker
in this case on my computer is running on Mac OS.
But here you see OIS architecture Linux and that's what I've told you before.
If you run Docker on Mac or Windows Docker creates small Linux virtual machine and that you see here
in this output next you see information about our processes that are running on our server like a container
of D around C and docker.
You need this process longer you need is a responsible for start of the dock etcetera.
This process is responsible of creation of containers at the high level but at the low level it communicates
with Iran C brought us around container.
This process works closely to linux kernel and it is responsible for allocation of resources to containers
for management of processes and so on and again Dr Sarah is simply set of different processes.
All right let me now quickly switch to a wound to Sarah and ant or same command here.
Dr. Morrison and I'll see similar output here as information about Docker client and here was information
blog about Docker.
Sara and Mike is here at this a boon to computer and here at this Matt Goss computer Docker and innovation
is the same night in all three but eight by difference is that here Docker engine was installed directly
on this one to computer and on Mac was Deloris Docker desktop that has created additional intermediate
small Linux your total machine.
All right guys that's all for this lecture.
And next.
Let's discuss what is our host and I'll demonstrate you what does look our host on Michael's computer
and a window computer.
I'll see you in the next lecture.
Bye bye.
