What is Jenkins?

In the early days of my career in Vmokshi, I was set up to help Jenkins develop an Android project. With the sole knowledge of Java Java software development these days, it was a challenge for me. First, I tried to understand what Jenkins is, why it is used, and how to help Android projects. I read the Jenkins Wikipedia article, but I do not understand much. So, I did a complete investigation to understand Jenkins.

I know that you are also looking for Jenkins who came from this site. I'm sure that when I read this page Jenkins, you will better understand Jenkins.

Introduction

Jenkins is a regular server (CI) in the java. It provides regular interconnections for software development that can be triggered from a phone or web application server. He was also happy to know that Jenkins is a free download and installation program.

Continuous integration

Before discussing Jenkins in detail, let me tell you about regular interaction (CI).

Permanent Integration (CI) is a development system that needs to be developed to interact with a multi-day code. This is a test procedure on a non-developer device (for example, experiments) when you enter a new store code. The following table shows the procedure CI.

In this type of system, it's a great advantage to know if all the jobs (Jenkins project estimates) work properly or not. But we can get an immediate answer. Responding to emergency situations is very important to always know after the break. You will receive detailed text messages on the console. You will know why it did not work, and you know how you can be. Using the CI Order Restriction Server will successfully run the screen and developers.

If the tasks are performed once, then there is a problem that there will be a lot of code changes since the last time. It is therefore difficult to figure out what has changed the problem. But when it's predicted that it will work directly on the coding box, it's always easier to know what and what the product produces.

Some of the reasons you need to automate in integration and integration are:

• Take the task to focus on matters: most of the work, such as interaction and investigation, is governed by the automotive industry and the test. Therefore, you can save the timer without losing a major error.

• Software quality improves: problems are immediately detected and resolved in a state of the software that can be triggered at any time.

• Improving development: most of the interdependent jobs are automated. Therefore, the adjustment problems are rare. This saves time and money in the life of the project.

In a vulnerable video, you can find tools like Jenkins, Bamboo and limited controls, etc. Bamboo has good support for UX, but not a free tool. Jenkins is an open source, easy to use and reserved code, as well as a lively social development that you love. We now have Jenkins tools.

Jenkins History

Jenkins originally crossed the Hudson project. The establishment of Hudson began in the summer of 2004 in Sun Microsystems. It was first introduced on java.net in February 2005.

In November 2010, the Hudson Group encountered a problem with the use of a building that raised questions about the management and management of Oracle. They negotiated with one of the largest project participants and Oracle, although there are many areas of the agreement, the Hudson brand was an important point after Oracle said it had the right to be nominated and that it had requested in December 2010. It was therefore On 11 January 2011 a call for a vote was cast, replacing the name of the "Hudson" project in "Jenkins". The Janami community widely accepted the proposal on 29 January 2011, thus forming the Jenkins project.

On February 1, 2011, Oracle says they want to continue developing Hudson and Jenkins deals as an account instead of changing the name. Jenkins and Hudson, then, go on Proceed with two independent projects, each of which requires action. In December 2013, Jenkins GitHub had 567 project projects and up to 1,100 publications, compared to 32 members of the Hudson project and 17 public sponsors.

Continuous Integration with Jenkins'

Jenkins is used for CI, which enables them to produce, perform, and test directly.

Let's make an event which is the entire application code and then perform the test server to perform the tests. It looks like a powerful way to improve the program, but this process has great disadvantages. So,

• The improvement should be stopped until the entire program is ready for the test results.

• It is very likely that the results of the research show a lot of mistakes. It's hard for developers to find it difficult to find the underlying reasons for these errors, as they need to provide all application requirements.

• Software payment program falls.

• There is a constant visualization of problems of selection or construction, crash, testing requirements, and publishing folders for folders so that the quality of the program can be reduced.

• The entire system was a manual that increased the risk of recurrence.

In the above troubles, it appears along with the software system and the quality of the program is reduced. This leads to a party attack. Therefore, in order to overcome these deficiencies, there is a great need for a system that developers could slowly interfere with interaction and any changes in source code identification. Therefore, Jenkins is used for CI. It's a big IQ device. Now we see how regular mediation in Jenkins destroys early problems.

For software development, most of them can be closed, such as SVN, Git, Mercurial, etc. Jenkins has a lot of free money. They help you to connect with various software tools for simplification.

One of the best things about Jenkins is that the installation of a configuration file will be a disk, which will make it easier to cut and re-organize the collection.

Benefits of Jenkins

• Jenkins is an open source tool with great support from your community.

• Installation is easy.

• It is more than 1000 perfect to facilitate work.

• Creating a new Jenkins is easy if you do not have it.

• Is a Java application. It can therefore resemble almost all major locations.

The following chart shows that Jenkins connects several levels of DevOps:

Most companies that integrate constant integration use regular customers to integrate applications, such as Jenkins. With Jenkins, organizations can develop software development through automation. Therefore, in general, Jenkins connects everyday life with all kinds of things, including creation, documentation, tests, packages, organizations, implementation, analysis, and much more.
