Overview Jenkins is a self-contained, open source automation server which can be used to automate all sorts of tasks related to building, testing, and delivering or deploying software. Jenkins can be installed through native system packages, Docker, or even run standalone by any machine with a Java Runtime Environment (JRE) installed (Jenkins.io). Prerequisites Vagrant, see how to install Vagrant here Add the following host entries on local device /etc/hosts : 1 2 192.

Overview Ansible is a radically simple IT automation engine that automates cloud provisioning, configuration management, application deployment, intra-service orchestration, and many other IT needs. Designed for multi-tier deployments since day one, Ansible models your IT infrastructure by describing how all of your systems inter-relate, rather than just managing one system at a time. It uses no agents and no additional custom security infrastructure, so it’s easy to deploy - and most importantly, it uses a very simple language (YAML, in the form of Ansible Playbooks) that allow you to describe your automation jobs in a way that approaches plain English.

Overview Kafka is a distributed system consisting of servers and clients that communicate via a high-performance TCP network protocol. It can be deployed on bare-metal hardware, virtual machines, and containers in on-premise as well as cloud environments. Servers: Kafka is run as a cluster of one or more servers that can span multiple datacenters or cloud regions. Some of these servers form the storage layer, called the brokers. Other servers run Kafka Connect to continuously import and export data as event streams to integrate Kafka with your existing systems such as relational databases as well as other Kafka clusters.

What is Configuration as a Service In micro-service world, managing configurations of each service separately is a tedious and time-consuming task. In other words, if there are many number of modules, and managing properties for each module with the traditional approach is very difficult. Central configuration server provides configurations (properties) to each micro service connected. As mentioned in the above diagram, Spring Cloud Config Server can be used as a central cloud config server by integrating to several environments.

Managing storage is a distinct problem from managing compute instances. The PersistentVolume subsystem provides an API for users and administrators that abstracts details of how storage is provided from how it is consumed. To do this, we introduce two new API resources: PersistentVolume and PersistentVolumeClaim.

Kubernetes, also known as K8s, is an open-source system for automating deployment, scaling, and management of containerized applications.
