1 00:00:04,550 --> 00:00:11,040 We have just discussed decided darker components as the doctor client and Doc Sara and you able to get 2 00:00:11,040 --> 00:00:17,250 information about dose components using darker version of command and basically now you know that the 3 00:00:17,250 --> 00:00:23,560 doc or Celera is set off processes like Doc or Damon container D. 4 00:00:23,700 --> 00:00:25,310 Ron C and dr. 5 00:00:25,310 --> 00:00:25,710 Indeed. 6 00:00:26,040 --> 00:00:31,320 And again if you go back to time and know and and or Dr. Morrison you'll see information about those 7 00:00:31,320 --> 00:00:32,759 processes here. 8 00:00:33,090 --> 00:00:43,130 But no question where those processes are Iranian they are running at Dr. Holst but what is Dr. host. 9 00:00:43,190 --> 00:00:45,120 Let me go back to this diagram. 10 00:00:45,230 --> 00:00:55,260 If you install Docker engine directly on Linux computer then this Linux machine is Docker host and all 11 00:00:55,280 --> 00:01:03,640 processes of Docker engine are actually running at this Docker host at this Linux machine if you are 12 00:01:03,640 --> 00:01:06,090 running a Mac OS or windows. 13 00:01:06,090 --> 00:01:13,650 Then as I have told you before you'll install tiny Linux your dole machine on top of Mac OS or Windows 14 00:01:13,650 --> 00:01:22,330 computer and this Linux of your Dell machine will be actually Docker host and inside of this dock our 15 00:01:22,330 --> 00:01:26,040 host will be running the same processes as the Doctor D. 16 00:01:26,090 --> 00:01:33,700 Ron C and so on and all containers will be created inside of these Docker host Linux of your Dell machine 17 00:01:34,630 --> 00:01:40,840 and the doors processes that are running inside of the dock our server communicate very tightly with 18 00:01:40,900 --> 00:01:46,890 Docker host for example processes create the new networks a docker host. 19 00:01:46,990 --> 00:01:48,570 Let me demonstrate to that. 20 00:01:48,700 --> 00:01:51,280 Let me first switch to a wound to your time machine. 21 00:01:51,280 --> 00:01:58,140 This one where Docker was already installed and looked me type command if conflict like this and I'll 22 00:01:58,150 --> 00:02:06,160 see here site network interface as Docker zero and its IP address is one hundred seventy two seventeen 23 00:02:06,300 --> 00:02:12,370 oh one if you have followed me along in the previous chapter when we have used a different Docker images 24 00:02:12,640 --> 00:02:20,140 then you could remember this IP address it is actually default gateway for all containers that are created 25 00:02:20,230 --> 00:02:25,570 in default breach network if you don't understand what I'm talking about right now we will get back 26 00:02:25,570 --> 00:02:32,520 to Docker networking a bit later but no I'll explain that you just concepts again at this computer want 27 00:02:32,540 --> 00:02:40,930 a computer there is new network interface gold Docker all zero and it has this IP address and all containers 28 00:02:41,020 --> 00:02:48,670 that will be created on this host Docker host we'll communicate with these IP orders as default gateway 29 00:02:48,760 --> 00:02:51,940 and go to Internet via eat for example. 30 00:02:51,940 --> 00:03:02,050 Let me quickly create the busy box container Docker Iran that's a deep busy box and here unable to find 31 00:03:02,080 --> 00:03:07,000 images the box latest locally let's wait to beat it we'll download the music box image from our hub 32 00:03:10,860 --> 00:03:11,190 OK. 33 00:03:11,220 --> 00:03:19,020 Image was loaded and here I could enter a command post name this I and IOC IP address assigned to this 34 00:03:19,020 --> 00:03:26,370 container and noticed that this IP address is from the same network as this IP address IP address of 35 00:03:26,460 --> 00:03:35,070 Docker zero interface on this one to computer and this actually proves that this Linux computer is Docker 36 00:03:35,100 --> 00:03:44,420 host all right let me know go back to this computer Marcus computer and go to a terminal here and let 37 00:03:44,420 --> 00:03:54,290 me clear it first and type if config and here in this output I will not see Docker zero interface doesn't 38 00:03:54,290 --> 00:04:02,790 because this Marcos computer is not Dr. Holst instead tiny doodle machine Linux your dollar machine. 39 00:04:02,910 --> 00:04:03,300 Yes. 40 00:04:03,350 --> 00:04:10,720 Dr. Holst but now you may ask me a question how we are able to get access to Dr. Holst on Mac OS or 41 00:04:10,720 --> 00:04:11,650 Windows computer. 42 00:04:12,370 --> 00:04:14,570 Let me demonstrate you that quickly. 43 00:04:14,740 --> 00:04:15,780 Let me clear timing though. 44 00:04:16,000 --> 00:04:22,880 And here in the history I have such kind of comment no I will not explain what this command does. 45 00:04:23,080 --> 00:04:30,270 But was this command you are able to get access to this new audio machine that acts actually as Dr. 46 00:04:30,280 --> 00:04:31,240 host. 47 00:04:31,570 --> 00:04:32,530 Let me press enter. 48 00:04:33,640 --> 00:04:36,910 And now I am inside of this building machine. 49 00:04:36,970 --> 00:04:46,220 Let me type if config command and here in this output I'll see Docker zero interface same interface 50 00:04:46,550 --> 00:04:48,920 as I have seen here on this computer. 51 00:04:50,230 --> 00:04:54,560 We save IP address one hundred seventy two 17 0 1. 52 00:04:54,970 --> 00:05:02,680 And that means that the docker host on Mac OS and Windows computers use actually Linux built a machine 53 00:05:03,010 --> 00:05:05,440 where all containers are created. 54 00:05:05,530 --> 00:05:13,190 That is Docker host and inside of these Docker host all processes like container D run C and took a 55 00:05:13,240 --> 00:05:16,950 demon running Wonderful. 56 00:05:17,040 --> 00:05:18,590 That's what is our host. 57 00:05:18,600 --> 00:05:25,230 And now you should understand actually what is the difference between Mac and Windows and Linux computers 58 00:05:25,320 --> 00:05:27,690 where Docker engine is installed. 59 00:05:27,840 --> 00:05:28,620 Let's not proceed. 60 00:05:28,650 --> 00:05:32,870 And next let me talk about Docker image and docker container. 61 00:05:32,880 --> 00:05:34,440 I'll see you next by my.
