Introduction to Jenkins training:
Jenkins training is a java application and it is a platform independent and it does not require any specific platform. You can use Jenkins the same way whether you are on Windows or Mac or any other operating system. It is used to build and test your software projects continuously which makes easy for the developer to integrate changes to the project. Jenkins is used to detect the changes whatever we commit using the version control system such as subversion or gate any other versioning system. Jenkins Training performs some tasks on the code, when it detects some changes in the code. Global online training is best in providing Jenkins Certification Training by real time experts.

Preview of Jenkins Training:
Jenkins training is primarily a build and release tool, it was written by the original community as a build and release tool, they did not target it as a continuous integration, continuous deployment or an orchestration tool. Jenkins training was simply used for releasing builds to production.
Learn about Continuous Integration in our Jenkins Training:
- The Jenkins CI is a CI server continuously integrates newly checked in code into a build and Jenkins detects those changes using the version control system and performs some tasks on them. It performs on building or testing on integration tests or deploying those bills. The continuous integration runs unit tests and rejects the bill. if they fail the continuous integration system detects and runs the unit tests and it detects the failure occurs during the unit text or integration test and any kind of test.
- It is going to rejects that build and send the information to the developer or the maintainer of that code. The continuous integration is also referred as build automation in Jenkins training.
- Many software projects are failing due to the integration hell. May be a better way would be to integrate continuously throughout the entire project and they therefore came up with the practice of continuous integration or CI.
- So rather than waiting until all the components are developed and then spending weeks or even months working at the bugs that will inevitably arise when components are integrated on a project.
- CI says that we must integrate early and we must integrate often and indeed it actually goes so far to say that we must integrate upon every single change. So every time a developer pushes new changes to the repository then ideally the project code should be checked out.
- It should be built in other words, compiled and all of its tests should be run and this way a team can ensure that the components being developed for a project interoperate correctly and the team doesn’t have this. Cloud of uncertainty looming over its head knowing that it is going to need to spend weeks or possibly even months at the end of the project getting its components to integrate properly.
- Jenkins Certification training at Global online trainings – Now if one is to rebuild a project and run all of its tests each time changes are pushed to the project repository then the entire process is going to need to be automated and this is exactly the purpose of a continuous integration server.
- So typically the process will work something like this a developer will push changes into the repository.so maybe a github repository for example and somehow the CI server will be notified of those changes. It will either pull the repository every few minutes to see if any changes have been pushed or the repository will actively call the CI server to let it know when a change is available.
Why do we need CI server?
- Well, first of all a developer might just forget to run the project tests before checking in his/her changes. On the other hand the CI server will never forget so any problems in the code will still be caught even if our developers forget to run their tests.
- Secondly, on even a modestly sized project to run all of the tests in the project could take anywhere from say 30 minutes or may be all night long many hours and therefore requiring a developer to run all of the project tests before checking in changes is often going to be infeasible though it’s useful to have a separate system on which all of the tests can be run and that system of course is the continuous integration server.
- In Jenkins training, So whatever the case when the CI server sees that changes have been pushed to the repository it will clone the repository on the server or may actually instruct a set of build servers to check out all of the code and then build the project and if the project fails to build it will send a notification to the team usually via email but assuming that the project does build it, will run all of the projects tests and if any tests fail it will then again send a notification to the team.
- And then finally the CI server will usually generate various reports such as the line coverage of the projects tests or maybe a report on style issues that were found in the project’s code. Of course developers should be running tests on their code before they check it into the project repository because we never want to be that guy who breaks the build.
Benefits of Continuous integration in our Jenkins Training :
- Jenkins CI system enables us in immediate bug detection. Bug will be detected some test fails or your build fails.
- CI system is going to deploy your code, if your test and your build passes at any given point it deployable system
- It record of evolution of your project.
- CI system is going to detect the system development problem at very early stage.
- Reduced risk of cost schedules and budget, when you detect the problem earlier obviously you are going to save on cost and you’re a time and budget
- The measurable and visible code quality, using the Jenkins training or any other CI system. It will be able to visibly see the code quality of the project.
- Develop a Jenkins Pipeline Script for CI CD of Docker training based application.
- Jenkins Training are using to create plug-ins, these plug-in are very modular.
- The Jenkins plug-in extensively makes Jenkins to adopt too many systems.
- There is install the Jenkins on many systems for example Linux, Windows or Mac operating system or any other system. If you are passionate about learning this course, we provide Jenkins training with real time scenarios.
- It is plug-in system is really modular, so it can install whatever plug-in want to support that kind of bill and functionality.
- Jenkins training- It provides everything for a robust continuous integration system, which helps a lot for team that practice agile.
- Agile is a software development techniques which are send widely across many companies and many are tams in order to co-ordinate their work.
- Jenkins training continuously provides access to the working copies of the software which supports the agile principles.
- Jenkins training is released under the MIT license; it is open source CI system.
- There is large support of community and through documentation.
- It is really easy to write a plug-in in Jenkins and if write a plug-in it can be used by other community member or use Jenkins.
- Jenkins training is really powerful in a way that a community member creates and they can be used by everybody who wants to use them.
Architecture of Jenkins training:
- Jenkins training allows you to be so effective at applying a continuous delivery devops environment. The server architecture really is broken up into two sections on one side you have the code the developers are doing and submitting that code to a source code repository and from then Jenkins is your continuous integration server and it will then pull anycode that’s been sent to the source code repository and will run tests against it.
- They will use a build service such as Maven to actually build the code and every single stage that we have that Jenkins manages. There are constant tests for instance if build fails feedback is sent right back to developers so that they can change the code so that the build environment can run effectively.
- The concluding stage is to actually perform specific test scripts and these test scripts can be written in Selenium. So it’s probably good to mention here that both Maven and Selenium are plugins that run in the Jenkins environment.
- Maven and Selenium are just two very popular examples of how you can extend the Jenkins environment. The goal to go through this whole process again it’s an automated process is to get your code form the developer to the production server as quickly as possible.
- Have it fully tested and have no errors. So it’s most likely important at this point to talk about one piece of information around the Jenkins environment that if you have different code bills that need to be managed and distributed.
- Jenkins training at Global online trainings – This will require that you need to have multiple builds being managed. Jenkins itself doesn’t permit for multiple files and builds to be executed on a single server. You need to have multiple server environments with running different versions of Jenkins for that to be able to happen.
Who can learn Jenkins? (Jenkins training)
- Basic Knowledge on scripting.
- Good knowledge on programming language.
- Knowledge of Maven/Ant is beneficial, Jenkins Pipeline, Devops. Some awareness of Server typologies and Release management is recommended.
So having knowledge on above mentioned concepts will help you to easily work on Jenkins.
Learn about Pipeline in our Jenkins Training:
Jenkin Online Training Providing best real time Pipeline Training. A bookish definition will say something like, Pipeline is a workflow with group of events or jobs that are chained together and work in a sequence.
- The every pipe will have a inlet and an outlet. Pipeline will consist of multiple sections of the pipe and it can also have multiple inlets and outlets.
- There is every section will do some processing and this processing in our case will be done by jobs.
- The section will have different jobs, so build section will have build jobs and then there will be a feedback or notification mechanism and similarly there will be other sections and jobs.
- All systems works together in a sequence in a way, we call it as continuous delivery pipeline.
- Pipeline as concept in Jenkins or as DevOps training in whole is mostly used with continuous delivery and deployment and integration system.
- The Pipeline is a system where multiple sections or job can be integrated in a sequence and work and workflow.
- It can be implemented in any ways.
Why Jenkins is used?(Jenkins training)
- Jenkins is used for continuous integration and continuous delivery. Now what do you mean by this continuous integration and continuous delivery? When we work in teams we have different developers who develop the code and they keep working on changing or enhancing the code and as the developers walks on his own machine and he changes the code he will check in the code in to some shared repository which can be GIT or Bit Bucket or TFS. We are good in providing Jenkins Certification training by real time experts.
- Do I have your attention? Let’s suppose through the entire day there are many developers who are changing the code and check in the code in the shared repository. At the end of the day when you have a build there is some bug introduced in any of the code and now the build failed. If you are interested in doing certifications, Global online trainings provide Jenkins certification training.
- Jenkins Training at Global online trainings – Now it will be very difficult for us to identify what exact code failed the build and at what point was this bug introduced in the code and then you have to go back and check in you know all the code that was created that day, there will be a lot of confusion.
- So here comes Jenkins, what does Jenkins do is? As soon as any developer commits the code in the shared repository Jenkins will take the latest code and trigger the build. The build notification will be sent out. So in case there is any problem with the build or there is any error you will get notified as soon as the build gets triggered and build is complete.our consultants are highly skilled at Jenkins training.
- So we can check that if there is any issue due to any commit we can reverse that and we will not waste a lot of time in finding out what code caused the break. The other thing is let’s suppose the build is successful we can also integrate our unit test or acceptance test or performance test along with the build as a post build actions in Jenkins and it will be automated as soon as the build gets deployed Jenkins will trigger some test cases or some testing which will be automated and it will send out a report back to us.
Example: (Jenkins Training)
- Let’s suppose build was successful there was no exception but due to the changes in the code there was something which broke the application so we will come to know instantly that there is some break due to this code and we can troubleshoot it. So you can see how efficient and powerful the entire system can be and this is what is called as continuous integration. We are taking the code and doing the build as soon as the code gets commit and then we are also triggering the test and we are sending back the reports.
- As soon as any change in the code this entire cycle gets triggered and we come to know if there is any issue with the application. So this is what continuous integration is all about.
If you are interested to learn advance topics on this course, we provide Jenkins corporate training with real time use cases.
Conclusion of Jenkins Certification Training:
In short, Jenkins training is a continuous integration tool used to build and deploying process. It will help developer to build and test software continuously. Jenkins requires little maintenance only because of this feature many organisations are going for this and has good built in GUI tool for easy updates. The continuous delivery Pipeline will consist of four major stages Build, Deploy, Test and Release. Every stage will have some jobs and these jobs are integrated with each other works in a sequence and we call it as continuous delivery pipeline. So this is what all about Jenkins. There is a huge demand in the market for Jenkins with high packages .So what are you waiting for? Come learn and be a part of Jenkins. Join today in Global online trainings for best Jenkins Training.
