KUBERNETES What are containers Before we dive into Container Orchestration, let's review first what containers are. Containers are an application-centric way to deliver high-performing, scalable applications on the infrastructure of your choice. With a container image, we bundle the application along with its runtime and dependencies. We use that image to create an isolated executable environment, also known as container . We can deploy containers from a given image on the platform of our choice, such as desktops, VMs, Cloud, etc. Container Orchestration ? In Development and Quality Assurance (QA) environments, we can get away with running containers on a single host to develop and test applications. However, when we go to production, we do not have the same liberty, as we need to ensure that our applications: Are fault-tolerant Can scale, and do this on-demand Use resources optimally Can discover other applications automatically, and c...
Jenkins Slave (Mac) Setup:- Go to Manage Jenkins and Select Manage Nodes Click on New Node Give the node name Give the executors Give the Remote Root Directory Specify a label name, For example: any custom name Select the launch method as: Launch agent via Java Web Start Click on Save, once done with above steps. Below the output, we see once after saving the changes. To start Mac Slave communication for Jenkins server Create a script for running the java JNLP from slave machine using the below content mentioned in the box. java -jar /Users/ssp/Downloads/slave.jar -jnlpUrl http://13.126.145.70:8080/computer/MacSlave/slave-agent.jnlp -secret 4c0a0370a9e9a46edfe939ccab0e9f4707715bd663587ab8c9e8e17287c1cf4c -workDir "/Users/ssp/jenkins" Put the above content in a script (ex: - Mac_Slave_On.sh) Give executable permissions to the script (ex: - chmod +x jenkins_slave.sh) Now To m...
Maven tutorial provides basic and advanced concepts of apache maven technology. Our maven tutorial is developed for beginners and professionals. Maven is a powerful project management tool that is based on POM (project object model). It is used for projects build, dependency and documentation. It simplifies the build process like ANT. But it is too much advanced than ANT. Current version of Maven is 3. Understanding the problem without Maven There are many problems that we face during the project development. They are discussed below: 1) Adding set of Jars in each project: In case of struts, spring, hibernate frameworks, we need to add set of jar files in each project. It must include all the dependencies of jars also. 2) Creating the right project structure: We must create the right project structure in servlet, struts etc, otherwise it will not be executed. 3) Building and Deploying the project: We must have to buil...
