1 00:00:04,280 --> 00:00:04,890 All right. 2 00:00:05,070 --> 00:00:10,890 I have just rearranged those two windows and stacked on top of each other in order to be able to leave 3 00:00:10,920 --> 00:00:12,630 my face here in this corner. 4 00:00:12,660 --> 00:00:13,410 So let's proceed. 5 00:00:13,440 --> 00:00:19,680 And in this lecture let's read the two different containers based on engine Nix image. 6 00:00:19,680 --> 00:00:23,530 And for that we will Sara files from different folders. 7 00:00:23,550 --> 00:00:25,190 Let's get right into it. 8 00:00:25,200 --> 00:00:31,740 Let's go to visual studio called and look that there was the folder on desktop and inside of it. 9 00:00:31,740 --> 00:00:33,290 There was engine X folder. 10 00:00:33,510 --> 00:00:39,840 And we have used this folder in order to set off some static files like index that this general and 11 00:00:39,840 --> 00:00:43,800 their faith icons to clients that used engine X web Sara. 12 00:00:43,950 --> 00:00:49,400 And now it's a good time to take this folder and make two copies of this folder. 13 00:00:49,500 --> 00:00:53,030 And they called them engine X1 and engine x2. 14 00:00:53,070 --> 00:00:59,670 And afterwards we will spin up to a different container as the running engine etc. and we will expose 15 00:00:59,670 --> 00:01:02,930 them to do different external boards on this computer. 16 00:01:03,270 --> 00:01:03,970 Let's do so. 17 00:01:04,200 --> 00:01:10,100 If you don't have this engine X folder you could take it from GitHub repository just clone it to find 18 00:01:10,110 --> 00:01:13,730 containers for that there and then find in Gen X folder. 19 00:01:13,890 --> 00:01:14,640 Great. 20 00:01:14,640 --> 00:01:16,790 Let me copied this folder. 21 00:01:16,800 --> 00:01:17,880 All right Miles click. 22 00:01:17,880 --> 00:01:21,480 Copy and paste here like so. 23 00:01:21,490 --> 00:01:22,790 And let me or name it. 24 00:01:22,800 --> 00:01:33,400 Press enter and it will be engine X one like so and let's make one more quote Bill based and let's name 25 00:01:33,400 --> 00:01:33,610 it. 26 00:01:33,650 --> 00:01:35,240 Engine x. 27 00:01:35,410 --> 00:01:43,180 Like so next door let's open up engine x 1 for the end open in this similar file down please for us 28 00:01:43,190 --> 00:01:47,600 to close this index said the decimal file that was opened in and Gen X folder. 29 00:01:47,720 --> 00:01:53,830 Okay so engine X1 and in the this gem L and TALF adjusted this text. 30 00:01:53,830 --> 00:02:00,100 Hello from the first and Gen X cetera. 31 00:02:00,130 --> 00:02:08,080 Like so let's save this file next to collapse and Gen X 1 folder expand in Gen X 2 folder and open in 32 00:02:08,380 --> 00:02:09,630 this GMO file there. 33 00:02:09,970 --> 00:02:11,980 And let's just text here. 34 00:02:12,010 --> 00:02:21,440 Hello from the 2nd and Jane etc. And also we could adjust the titles here and instead of a document 35 00:02:21,470 --> 00:02:29,950 here we'll be in let's say NGO x 2 and let's save this file gold 2 engine x 1 folder and index location 36 00:02:29,950 --> 00:02:37,220 all file instead of that folder and adjust document here and here we'll be engine X one let's say save 37 00:02:37,220 --> 00:02:43,070 the file and now we are all set and now we're able to start two different containers in two different 38 00:02:43,070 --> 00:02:43,940 folders. 39 00:02:44,090 --> 00:02:44,540 Great. 40 00:02:44,540 --> 00:02:51,580 Let me close the doors to index AGM all files and gold all time and all record that we have started 41 00:02:51,580 --> 00:02:59,150 the stand alone and Jennings container using the B WD variable and now we will do the same but if you 42 00:02:59,150 --> 00:03:05,060 want to use variable instead of absolute Beth you need to first Cydia to a corresponding folder that 43 00:03:05,060 --> 00:03:12,080 has needed files and only then run Docker on command inside of that folder let's do so here we'll be 44 00:03:12,080 --> 00:03:19,670 in Jane except one server and here we'll be in Gen X 2 Sara let's see did 2 desktop containers in Jane 45 00:03:19,670 --> 00:03:28,630 X one like so and here let's see two desktop containers in Gen X two great let's not start the engine 46 00:03:28,630 --> 00:03:35,840 X one contender and for that we will use as usually dock our on command next let's expose support DSP 47 00:03:36,200 --> 00:03:46,550 and let's run engine x 1 etc. on board let's say 5 5 5 5 and internal port will be 8 and next that comes 48 00:03:46,610 --> 00:03:51,990 well you might be in the stream here we'll be a variable BMW Dean. 49 00:03:52,040 --> 00:03:58,900 Next comes Colin and after Colin you need to specify path to files inside of that container and the 50 00:03:58,900 --> 00:04:05,490 this path is yours user Sharon and Jane Nicks HMO like so. 51 00:04:05,660 --> 00:04:08,150 And finally comes the name of. 52 00:04:08,300 --> 00:04:15,350 And Jane Nicks image and Jane Nicks also optionally youcan specify name of the container recap that 53 00:04:15,410 --> 00:04:20,870 if you don't because if I name of the container and then Docker will generate a random name and you 54 00:04:20,870 --> 00:04:26,150 have seen that such random names before but you are able to add custom name if you want to and for that 55 00:04:26,210 --> 00:04:33,980 you could use option does that name and here let's name this container N.J. and this one like so great 56 00:04:34,370 --> 00:04:37,430 let's press enter and see what will happen. 57 00:04:37,640 --> 00:04:43,700 Container was running we're actually inside of it and we are ready to see some looks great let's now 58 00:04:43,700 --> 00:04:52,760 do the same here for engine next 2 etc. Docker run this beep let's expose it to port 6 6 6 6 like so 59 00:04:52,790 --> 00:04:58,370 and internal port we'll be again aided because the support that is opened by engine X cetera inside 60 00:04:58,370 --> 00:05:06,080 of the container by default next comes the volume might be the same variable BW deem it is important. 61 00:05:06,110 --> 00:05:12,940 Same variable and it will be replaced by absolute path for each of those folders in Gen X to end in 62 00:05:12,940 --> 00:05:20,210 Gen X 1 in our cases and here let's after Colin specify the same internal folder use our Cheryl and 63 00:05:20,210 --> 00:05:29,000 Jane Nicks age demo and let's give name to this container and Gen X 2 and Gen X Okay let's press enter 64 00:05:29,030 --> 00:05:32,150 and start this second and Gen X etcetera. 65 00:05:32,270 --> 00:05:37,550 Now we are all set and those two containers are no running and in order to verify that you will simply 66 00:05:37,580 --> 00:05:45,170 open up a Google Chrome and try to connect the doors to both 5 5 5 5 and 6 6 6 6 let us know so let's 67 00:05:45,170 --> 00:05:51,710 go to Google Chrome and here we could use a local host Buttercup that you're also able to use all back 68 00:05:51,740 --> 00:05:57,170 IP address 127 to 0 0 1 or any of the IP addresses of your computer. 69 00:05:57,560 --> 00:06:05,560 I'll use a local host so local host and here let's connect to frost and Jane etc. hello from dethroned 70 00:06:05,660 --> 00:06:17,590 and Jane etc. Let's open up new tab the local host column 6 6 6 6 say it cannot be reached. 71 00:06:17,670 --> 00:06:18,540 Something is wrong. 72 00:06:18,540 --> 00:06:23,560 Let's go to Diamond now and verify what's actually happening here. 73 00:06:23,640 --> 00:06:30,530 Users share sharing Nix no looks here and the commander to walking properly. 74 00:06:30,970 --> 00:06:32,110 Let's go back to Chrome. 75 00:06:32,750 --> 00:06:33,110 Yeah. 76 00:06:33,220 --> 00:06:36,770 Actually I see here error error or unsafe port. 77 00:06:36,820 --> 00:06:42,140 It seems that I'm not able to expose the sites 4 to 6 6 6 6. 78 00:06:42,160 --> 00:06:45,780 Okay let's rerun this container and the use and USB port. 79 00:06:45,790 --> 00:06:56,440 Let's close this and let's run it at the port let's say 7 7 7 7 and I see error from Doctor error response 80 00:06:56,440 --> 00:06:57,560 from Damon conflict. 81 00:06:57,580 --> 00:07:04,030 The container name and Jane x2 is already in use by another container but actually I have just stopped 82 00:07:04,090 --> 00:07:09,660 this container with custom name but it still exists and you are able to start it over again. 83 00:07:09,760 --> 00:07:14,030 You could verify that by entering Docker appears and you should see only one container running. 84 00:07:14,050 --> 00:07:15,270 And yes that is a case. 85 00:07:15,280 --> 00:07:17,960 Here we send this container that is running here in this window. 86 00:07:18,160 --> 00:07:24,670 But if you'll die a doctor be a sub that's a you'll see that this container should be somewhere at the 87 00:07:24,670 --> 00:07:31,300 top was exhausted but it is still available for use and you are able to restart it if you want to here 88 00:07:31,300 --> 00:07:34,340 with actually this container was named in Jan 2. 89 00:07:34,360 --> 00:07:39,460 That's why we need to remove this contained our heroes before starting container was the same name and 90 00:07:39,490 --> 00:07:46,450 I could remove container by type in Docker R M and here we'll be eyes our I.D. of the container or its 91 00:07:46,450 --> 00:07:54,280 name we could use your name and Jane X to like so container was removed and now I am able to try to 92 00:07:54,280 --> 00:07:56,690 start a container with the same name again. 93 00:07:56,830 --> 00:07:58,200 Let's clear terminal here. 94 00:07:58,510 --> 00:08:06,190 And again goes back to history and I find this comment and let's try to start this container and expose 95 00:08:06,190 --> 00:08:08,440 port 7 7 7 7. 96 00:08:08,660 --> 00:08:09,900 Enter. 97 00:08:10,100 --> 00:08:18,470 Let's go to Rome and here instead of this port let's use this port and to and I see a response hello 98 00:08:18,470 --> 00:08:20,350 from the second engine etc.. 99 00:08:20,460 --> 00:08:22,100 Basically I have no idea why. 100 00:08:22,170 --> 00:08:25,460 Port 6 6 6 6 is considered unsafe. 101 00:08:25,460 --> 00:08:27,580 Actually let me google it quickly. 102 00:08:27,730 --> 00:08:29,130 6 6 6 6. 103 00:08:29,260 --> 00:08:36,070 UN safe port and let's check out this first link which ports are considered unsafe. 104 00:08:36,070 --> 00:08:44,039 Vikram Let's scroll down a bit and here is a list of all ports that are considered as are restricted. 105 00:08:44,049 --> 00:08:50,530 Actually you see here a list of default ports for different applications like ports 22 for SSA age and 106 00:08:50,530 --> 00:08:51,270 so on. 107 00:08:51,280 --> 00:08:59,070 And let me scroll down and yes here is a list of ports in this range and this port all six is an alternate 108 00:08:59,080 --> 00:09:01,450 to IRS sea application port. 109 00:09:01,510 --> 00:09:04,510 Actually I don't know what is I.R.S.. 110 00:09:04,600 --> 00:09:05,380 Let me check. 111 00:09:05,410 --> 00:09:06,010 What does that. 112 00:09:06,030 --> 00:09:14,160 Quigley see is Internet Relay Chat is a system that facilitates transfer of messages in the form of 113 00:09:14,160 --> 00:09:14,740 text. 114 00:09:14,770 --> 00:09:15,220 Okay. 115 00:09:15,310 --> 00:09:17,760 To some sort of chat and application. 116 00:09:17,820 --> 00:09:18,350 Great. 117 00:09:18,390 --> 00:09:25,080 That's how we found out that we are not able to expose the same support and use it for our gen Gen-X 118 00:09:25,200 --> 00:09:27,150 cetera or any of or container basically. 119 00:09:27,510 --> 00:09:28,230 Great. 120 00:09:28,230 --> 00:09:29,050 We have a dude. 121 00:09:29,050 --> 00:09:34,320 Actually our goal and we are able to summarize what we have achieved in this location and we have agreed 122 00:09:34,320 --> 00:09:37,800 that the two different engine accelerators here was there. 123 00:09:37,820 --> 00:09:44,130 Sarah and we have set up content from the engine X one folder and here was the second engine. 124 00:09:44,130 --> 00:09:48,420 Sarah and Sarah was content from the engine to fall drunk. 125 00:09:48,450 --> 00:09:50,510 And here we have actually verified that. 126 00:09:50,580 --> 00:09:52,790 Here you see Hello from the second engine etc.. 127 00:09:52,800 --> 00:09:55,450 And here is the document title engine x2. 128 00:09:55,530 --> 00:10:01,950 And he and this Deb used to document title engine X1 and hello from the first engine etc. And of course 129 00:10:02,160 --> 00:10:08,340 any time when you'll edit the files and those to follow the rules and refresh page afterwards and Google 130 00:10:08,340 --> 00:10:10,410 Chrome you'll see updated page. 131 00:10:10,410 --> 00:10:17,910 For example if I change in the HMO file here in engine X to folder and add one more exclamation mark 132 00:10:17,910 --> 00:10:24,630 here go to Google Chrome back go to engine x2 refresh page you'll see updated the text here. 133 00:10:24,900 --> 00:10:30,660 That's how you're able to start the multiple engine accelerators but it is important that you need to 134 00:10:30,660 --> 00:10:38,190 use different external boards and because on your computer each board may be utilized only by one application. 135 00:10:38,490 --> 00:10:44,970 And in this case those two boards this port and the this port will be actually forwarded to dock Horst 136 00:10:45,060 --> 00:10:49,600 and it will actually proxy indoor sports correspondent containers. 137 00:10:49,620 --> 00:10:51,360 That's how it works under the hood. 138 00:10:51,360 --> 00:10:51,920 Great. 139 00:10:51,960 --> 00:10:53,180 That's all for this logo. 140 00:10:53,190 --> 00:10:54,310 I hope that you enjoyed it. 141 00:10:54,330 --> 00:11:00,600 And we have found some interesting stuff and the nice low let's start with Python and let's create simple 142 00:11:00,600 --> 00:11:03,780 python application and run it inside of the container. 143 00:11:03,780 --> 00:11:05,210 I'll see you in the next lecture. 144 00:11:05,280 --> 00:11:05,540 My.
