DevOps.... CI/CD

Jenkins is the main CI tool used in Software industry. This is the backbone tool for all CI and CD implementation, Build - release and deployment methods. With the help of 100s of plugin available around the jenkins, We can achieve so much of automation around build process including build/deployment pipeline, notification, analysis, pre and post build action etc. Jenkins has tremendous power to perform great amount of work around the core build process. Many time we write script in pre and post build action to perform many tasks which is becoming very command and necessary for automation. But the main limitation in running shell script is that it's very difficult to make it more human readable for errors and make it fancy. Today i am going to cover some steps to make the output of shell script colour formatted.

Even a small change can make the platform less stable or result in problems. Vishal Sahasrabuddhe talks about his experiences using Jenkins and offers tips to take advantage of its many powerful features to automate deployment and increase productivity and product quality. (Originally published on  cmcrossroads.com ) Configuration management requires that you automate application build, package, and deployment. There are many tools used to accomplish these tasks, but Jenkins is one of the most popular open source frameworks employed by teams today. Jenkins is widely used by developers to automate not only application procedures, but also continuous integration and continuous delivery. It comes with many powerful built-in features, and there are also hundreds of plugins that help it integrate with other tools and p...

Author of Mastering Jenkins [Packt Publishing] [ http://www.masteringjenkins.com ] Kohsuke Kowaguchi designed and developed the Hudson automation system from the ground up while he was working at Oracle in 2006.  Primitive inceptions of the Jenkins platform (then known as Hudson) simply aimed to support continuous integration practices and offer a viable replacement for CruiseControl, which was the popular CI solution at the time. The Hudson platform was initially very Java centric with tight coupling to Maven and Java development paradigms. Little did Kohsuke know that his internal Hudson tool would catapult in notoriety, change names (into Jenkins), spin off to become CloudBees and eventually become the most popular modern Continuous Integration and automation orchestration platform in use in modern history. The current Jenkins platform provides an easily consumable unified user interface coupled with a highly scalable distributed automation solution that can build, t...

In this section I will talk about Tips, Tricks, Troubleshooting of jenkins plugins. Role strategy Plugin This plugin adds a new role-based strategy to ease and fasten users management. You can even define pattern for the job and assign access for those jobs to users. Tip - > While specifying the pattern add the "." before "*", Otherwise pattern will not work. Ex-               test* will not match the job name which starts with test , You will need to add "." like test.* to match the job name starts with test.

Some time Jenkins Slaves are neither showing any log nor getting connected and you may feel that its stuck somewhere. Problem – The main problem could be the last connection was not cleaned up properly and its hung that is why nothing is shown in UI log. Solution – Try to disconnect and kill the process in slave if any and then try to reconnect again . Another option is that try to reconfigure slave with wrong config (say wrong port) are relaunch again, It will fail and cleanup connection, again configure back and relaunch, this should work.
