1 00:00:00,005 --> 00:00:02,002 - [Instructor] With our POC implementation 2 00:00:02,002 --> 00:00:04,002 completed on dev side, 3 00:00:04,002 --> 00:00:08,003 we are all set to deploy our proof of concept to production, 4 00:00:08,003 --> 00:00:10,007 so let us take a look at what we have here. 5 00:00:10,007 --> 00:00:12,008 I have one EC2 instance 6 00:00:12,008 --> 00:00:16,009 which I have connected through remote desktop or RDB. 7 00:00:16,009 --> 00:00:20,008 Through this RDB I have installed Apache Tomcat 8 00:00:20,008 --> 00:00:24,008 and inside the folder I can go into bin 9 00:00:24,008 --> 00:00:27,000 and get this server started. 10 00:00:27,000 --> 00:00:29,008 You can see that the server is up and running. 11 00:00:29,008 --> 00:00:32,007 I can test that by going into browser 12 00:00:32,007 --> 00:00:36,001 and then getting into localhost 8080 13 00:00:36,001 --> 00:00:40,008 this webpage shows that my server is up and running. 14 00:00:40,008 --> 00:00:42,000 We should also test 15 00:00:42,000 --> 00:00:43,004 connecting to this Tomcat 16 00:00:43,004 --> 00:00:46,001 from some other machine outside the RDB 17 00:00:46,001 --> 00:00:47,003 just to make sure 18 00:00:47,003 --> 00:00:50,006 that we are able to access it from public domain. 19 00:00:50,006 --> 00:00:53,006 For that, I'll go back to my bank machine 20 00:00:53,006 --> 00:00:57,000 here you see my EC2 management console 21 00:00:57,000 --> 00:00:59,005 showing the EC2 instance 22 00:00:59,005 --> 00:01:04,000 and you can also see the public DNS, which I can copy. 23 00:01:04,000 --> 00:01:06,008 Go to my browser. 24 00:01:06,008 --> 00:01:08,009 Type in the port 8080 25 00:01:08,009 --> 00:01:10,005 and you will see once again 26 00:01:10,005 --> 00:01:13,003 the same web server up and running. 27 00:01:13,003 --> 00:01:15,000 Now to make this happen. 28 00:01:15,000 --> 00:01:19,003 Make sure that your EC2 instance has public access, 29 00:01:19,003 --> 00:01:22,000 it Security groups allow port 8080 30 00:01:22,000 --> 00:01:24,006 to be accessed through HTTP 31 00:01:24,006 --> 00:01:28,003 and optionally if needed HTTPS 32 00:01:28,003 --> 00:01:33,003 and also that EC2 firewall is not blocking port 8080. 33 00:01:33,003 --> 00:01:36,002 If it is you need to go into firewall settings 34 00:01:36,002 --> 00:01:38,009 and unblock 8080. 35 00:01:38,009 --> 00:01:41,008 Now going back to my remote desktop, 36 00:01:41,008 --> 00:01:46,005 I want to look at the configuration files for Apache Tomcat, 37 00:01:46,005 --> 00:01:48,008 which are important for our application. 38 00:01:48,008 --> 00:01:51,000 So I go into con folder. 39 00:01:51,000 --> 00:01:53,004 There are two files that we are interested in 40 00:01:53,004 --> 00:01:55,009 Tomcat users and context, 41 00:01:55,009 --> 00:01:59,003 so let's open that and in Tomcat users 42 00:01:59,003 --> 00:02:02,003 you see that I have included the deployer user 43 00:02:02,003 --> 00:02:04,004 that has managed a scriptural, 44 00:02:04,004 --> 00:02:06,007 this is the user that will use Jenkins 45 00:02:06,007 --> 00:02:08,007 to deploy the warfighter. 46 00:02:08,007 --> 00:02:10,006 Then in context XML, 47 00:02:10,006 --> 00:02:12,002 here is the resource. 48 00:02:12,002 --> 00:02:14,008 It has the data source red30db, 49 00:02:14,008 --> 00:02:16,009 that is our production database 50 00:02:16,009 --> 00:02:20,008 and you can see that it is pointing to the RDS. 51 00:02:20,008 --> 00:02:23,004 Where do I get this URL from? 52 00:02:23,004 --> 00:02:25,006 Let me go back to my dev machine. 53 00:02:25,006 --> 00:02:30,005 Now I am on my IDS management console in databases. 54 00:02:30,005 --> 00:02:32,007 Here is my production database 55 00:02:32,007 --> 00:02:34,001 and if I click there, 56 00:02:34,001 --> 00:02:36,008 I can see the URL along with the port 57 00:02:36,008 --> 00:02:38,008 where my production DB is running. 58 00:02:38,008 --> 00:02:41,001 I can connect to this database 59 00:02:41,001 --> 00:02:43,003 through my SQL workbench. 60 00:02:43,003 --> 00:02:45,007 You can see that I was connecting initially 61 00:02:45,007 --> 00:02:47,000 to my local instance, 62 00:02:47,000 --> 00:02:49,000 which was my dev server, 63 00:02:49,000 --> 00:02:51,005 and here is my production data server. 64 00:02:51,005 --> 00:02:52,008 If I click on it, 65 00:02:52,008 --> 00:02:55,000 I can get to the database 66 00:02:55,000 --> 00:02:58,003 and you can see that I am using the same four tables 67 00:02:58,003 --> 00:03:01,000 that we have been with so far. 68 00:03:01,000 --> 00:03:03,009 Now the only thing left is Jenkins, 69 00:03:03,009 --> 00:03:06,004 which is supposed to deploy the war file, 70 00:03:06,004 --> 00:03:08,000 but before we do that, 71 00:03:08,000 --> 00:03:10,005 how about let us deploy it manually 72 00:03:10,005 --> 00:03:12,002 just to see how it works 73 00:03:12,002 --> 00:03:15,006 and then deploy it later through Jenkins. 74 00:03:15,006 --> 00:03:18,003 So let me go back to eclipse 75 00:03:18,003 --> 00:03:22,009 and here on my project I say run as 76 00:03:22,009 --> 00:03:25,006 and maven build. 77 00:03:25,006 --> 00:03:29,007 Here I specify the goal as package, 78 00:03:29,007 --> 00:03:36,009 which will create the war package for me and then run. 79 00:03:36,009 --> 00:03:40,002 Now you can see that the build is successful, 80 00:03:40,002 --> 00:03:43,005 which means my war file has been created, 81 00:03:43,005 --> 00:03:46,005 which I can find in my target folder. 82 00:03:46,005 --> 00:03:53,004 I go into that folder right click show in system Explorer, 83 00:03:53,004 --> 00:03:59,000 copy the file so that I can copy it to my Tomcat server. 84 00:03:59,000 --> 00:04:03,003 Go back to my EC2 instance 85 00:04:03,003 --> 00:04:09,006 into file Explorer from Apache Tomcat go into web apps 86 00:04:09,006 --> 00:04:13,005 and paste the war file. 87 00:04:13,005 --> 00:04:14,006 As you do that, 88 00:04:14,006 --> 00:04:17,007 if you open up your Tomcat instance, 89 00:04:17,007 --> 00:04:20,002 you can see that the server could detect 90 00:04:20,002 --> 00:04:22,000 a new application war file. 91 00:04:22,000 --> 00:04:25,007 It exploded it and now is loading the data. 92 00:04:25,007 --> 00:04:26,008 This may take a while 93 00:04:26,008 --> 00:04:30,009 because it is pulling the data from Amazon cloud. 94 00:04:30,009 --> 00:04:35,000 Now you can see that the application has been uploaded. 95 00:04:35,000 --> 00:04:38,009 I go back to my browser on my local instance 96 00:04:38,009 --> 00:04:42,009 and say red30 run the POC 97 00:04:42,009 --> 00:04:46,002 and you can see that we are getting the desired result. 98 00:04:46,002 --> 00:04:49,002 I can also test this out on my dev machine. 99 00:04:49,002 --> 00:04:52,008 So let me go back there onto the browser, 100 00:04:52,008 --> 00:04:54,006 back to the page where we had 101 00:04:54,006 --> 00:04:56,009 our EC2 instance server running 102 00:04:56,009 --> 00:04:59,003 and say red30. 103 00:04:59,003 --> 00:05:03,003 Once again, POC and we see the desired result again. 104 00:05:03,003 --> 00:05:07,005 Now we need to do this entire cycle using Jenkins 105 00:05:07,005 --> 00:05:10,001 for that let me go back to eclipse 106 00:05:10,001 --> 00:05:11,006 and make a small change 107 00:05:11,006 --> 00:05:16,004 so that you can see the change going back to production. 108 00:05:16,004 --> 00:05:20,001 So let me open up the airbag folder inside 109 00:05:20,001 --> 00:05:22,005 which I have POC results 110 00:05:22,005 --> 00:05:24,005 and here I'll make a tiny change. 111 00:05:24,005 --> 00:05:30,002 I'll say, wow, I found save this. 112 00:05:30,002 --> 00:05:32,004 Now I'll go into get staging. 113 00:05:32,004 --> 00:05:34,002 You can see that all the files 114 00:05:34,002 --> 00:05:35,005 that we have been working on 115 00:05:35,005 --> 00:05:38,007 are showing up as onstage changes. 116 00:05:38,007 --> 00:05:43,004 I will stage them and then push them to get. 117 00:05:43,004 --> 00:05:45,007 So here I will put in my lesson number 118 00:05:45,007 --> 00:05:51,004 which is 02-07e 119 00:05:51,004 --> 00:05:56,004 and we can say POC completed as the comment, 120 00:05:56,004 --> 00:06:00,006 comment and push, here you see that it is 121 00:06:00,006 --> 00:06:05,003 pushing you to the master now to Jenkins. 122 00:06:05,003 --> 00:06:10,005 Now in Jenkins I have created a deploy red30 project 123 00:06:10,005 --> 00:06:12,006 as a freestyle project. 124 00:06:12,006 --> 00:06:14,006 If I go inside the project, 125 00:06:14,006 --> 00:06:17,004 I can see its configuration settings. 126 00:06:17,004 --> 00:06:20,000 Starting from here with a general description 127 00:06:20,000 --> 00:06:21,008 and source code management, 128 00:06:21,008 --> 00:06:23,008 it is pointing to my good report 129 00:06:23,008 --> 00:06:26,005 with the credentials in build. 130 00:06:26,005 --> 00:06:28,008 I have the Maven plugin 131 00:06:28,008 --> 00:06:31,005 and I'm giving the goal of clean package 132 00:06:31,005 --> 00:06:33,002 to create a war file, 133 00:06:33,002 --> 00:06:37,009 which will be deployed in the context red30 134 00:06:37,009 --> 00:06:40,005 add the URL specified here, 135 00:06:40,005 --> 00:06:43,004 which requires these credentials. 136 00:06:43,004 --> 00:06:48,006 So let me save this setting and go into build now. 137 00:06:48,006 --> 00:06:50,002 This takes a while because it has 138 00:06:50,002 --> 00:06:53,008 to pull all the code from get creative or file, 139 00:06:53,008 --> 00:06:57,003 and then deploy it on Amazon server. 140 00:06:57,003 --> 00:07:00,008 Excellent we see that our build has been successful, 141 00:07:00,008 --> 00:07:06,003 so I can go back to my URL and simply refresh, 142 00:07:06,003 --> 00:07:08,003 and you can see that the change is showing up 143 00:07:08,003 --> 00:07:10,001 on the production site. 144 00:07:10,001 --> 00:07:12,006 Now our dev ops pipeline is running 145 00:07:12,006 --> 00:07:16,000 and we can start delivering our product increments.
