If you’re involved in Software Development & DevOps, you’d have noticed Jenkins. Jenkins is used for Continuous Integration and Deployment (CI/CD). To use it for CI/CD, we need to have a Plugin for Jenkins. So, in this post, we’ll be covering some of the most popular Jenkins plugins for devops.
The DevOps plugin is a very popular, powerful and easy to configure Jenkins plugin that allows you to trigger jobs by using Docker. Now, why would you want to do this? The DevOps plugin offers several scenarios that could benefit your job’s pipeline.
Awesome! I was looking for a Jenkins plugin that makes it easier for me to deploy my apps. I found one!
Jenkins Plugin For Devops
1) Git plugin for Jenkins
Among the extensive list of plugins for Jenkins, the Git plugin holds a prominent position. As the name suggests, it facilitates essential git functions for Jenkins projects. It offers Git operations such as pulling, fetching, checking out, branching, listing, merging, tagging, and pushing repositories. Git plugin has the functionality, performance, security, and flexibility that the DevOps teams need. It serves as a Distributed Version Control DevOps tool that supports distributed non-linear workflows by providing data assurance for developing quality software. Moreover, it enables access to GitHub as a Source Code Management (SCM) system, which acts as a repository browser for many other providers.

2) Jira plugin for Jenkins
Jira plugin is one of the most popular and sought-after ticketing tools. It is an open-source plugin that integrates Jenkins with the Atlassian Jira Software (both Cloud and Server versions), enabling the DevOps teams more visibility into the development pipeline. This plugin also allows you to display builds inside Jira, automatically send data about builds and developments from Jenkins to Jira, and track Jira issues in Jenkins, among other vital functions.
However, one ought to use a Jira service account instead of a personal account for leveraging the Jira plugin.
In order to configure the Jira plugin, one must add Jira sites in Jenkins, then the plugin will automatically hyperlink all the corresponding issue names to Jira.

3) Kubernetes plugin for Jenkins
It is no surprise that the Kubernetes plugin holds a spot in the list of plugins for Jenkins. However, running multiple projects simultaneously on Jenkins can be a tough row to hoe as it doesn’t facilitate great server scalability. This is where the Kubernetes plugin comes in.
This plugin integrates Jenkins with Kubernetes. It enables developers to automate the scaling process of running Jenkins slaves in the Kubernetes environment.
This plugin integrates Jenkins with Kubernetes. It enables developers to automate the scaling process of running Jenkins slaves in the Kubernetes environment. It is excellent for running dynamic agents on the Kubernetes clusters. More importantly, it dynamically creates Kubernetes Pods for each agent defined by the Docker image to run and terminate it after the build is completed.
To configure this free plugin, one must add the Kubernetes cluster in the Jenkins configurations. Then, navigate to Manage Jenkins -> Configure System -> Cloud -> Kubernetes to set up this plugin. In fact, if Jenkins is running on the cluster, the default configuration values can be used.

4) SonarQube Plugin for Jenkins
SonarQube plugin enables easy integration of SonarQube with Jenkins. SonarQube is the open-source tool for Continuous Inspection of code quality. So, the SonarQube plugin helps DevOps teams to identify bugs, vulnerabilities, and duplication and ensure code quality before building code automatically with Jenkins. In addition, the integration enables you to analyze the code when you run a job that contains SonarQube execution within it. It also generates an analysis of that code in the SonarQube Server.
Navigate to Manage Jenkins –> Manage Plugins > Available –> SonarQube to install the SonarQube plugin. Moreover, include credentials plugins to store your credentials in Jenkins.

5) Docker plugin for Jenkins
Docker plugin is one among the top Jenkins plugins for enhancing DevOps. This plugin allows one to spawn Docker containers and run builds on them automatically. With this plugin, DevOps teams can use a Docker host to dynamically provision a docker container as a Jenkins agent node that runs a single build. The node can be terminated without the build process needing any awareness of Docker.
Jenkins can be configured with knowledge of one or more docker hosts and templates. Then, it can run Docker containers to offer Jenkins Nodes on which Jenkins can run builds.

6) Maven Integration Plugin for Jenkins
Although Jenkins has in-built support for Maven, it still lacks advanced integration features. Maven Integration plugin does the needful. This plugin offers advanced integration of Maven 2/3 projects with Jenkins. The functionalities of this plugin are as follows:
Ø Automatic configuration of reporting plugins such as Junit and Findbugs
Ø Automatic triggering across jobs on the basis of SNAPSHOTs published or consumed
Ø Incremental builds
Ø Parallel build modules on multiple executors or nodes
Ø Post-build deployment of binaries, if all tests are passed, and the project is succeeded
To install the Maven Integration plugin, go to Manage Jenkins -> Select Manage Plugins -> Available -> Maven Integration plugin.

7) Amazon EC2 Plugin for Jenkins
Amazon EC2 plugin enables Jenkins to initiate agents on EC2 (or Eucalyptus) and terminate when they get obsolete. When the build cluster is overburdened, Jenkins – with this plugin – starts instances using the EC2 API and connects them as Jenkins agents. The excess EC2 instances will be killed once the load becomes normal. In this way, the DevOps teams can maintain an in-house cluster, then move the excess build/test loads into EC2. Moreover, this plugin helps in copying artifacts and managing the load for Jenkins.
To install this plugin, go to Manage Plugins -> Available -> Amazon EC2 -> Download now and install after restart. Once the installation is complete, restart Jenkins.

8) Build Pipeline Plugin for Jenkins
Build Pipeline plugin is another interesting Jenkins plugin that secured a spot in the top 10 list. It allows DevOps teams to view all the upstream and downstream connected jobs within the build pipeline. With this plugin, manual triggers can be defined for jobs that need intervention before execution. The Build Pipeline plugin also helps you view the history of pipelines, the present status, and where each version got into the chain based on its revision number in VCS.
To install the build pipeline plugin, go to Jenkins -> Manage Jenkins -> Build Pipeline Plugin.

Troubleshooting: What to do if Jenkins plugins are not installing?
While installing Jenkins plugins, you may often encounter installation troubles. Some of the common Jenkins plugins installation problems are given below:
– The Jenkins plugin is abnormal during initialization
There may be two common reasons for this issue. 1) The Jenkins version is outdated, and the particular plugin cannot be used. 2) The plugin cannot be installed due to network or wall problems.
In the first case, you must download the latest Jenkins version and, in the second instance, change the plugin proxy source.
– The plugin cannot be found, or the installation fails
The reasons for this issue are the same as the above one. In this case, you must manually download relevant plugins from the Jenkins plugin official website https://plugins.jenkins.io/. After the download is complete, you can upload it manually.
These are just a couple of issues DevOps teams face while installing Jenkins plugins. However, with so many plugins required for seamless DevOps workflow, one may unwittingly find themselves in the crosshairs of installation issues. This is where the services of Opsera prove worthy.
