Overview of this book

Continuous Delivery with Docker and Jenkins, Second Edition will explain the advantages of combining Jenkins and Docker to improve the continuous integration and delivery process of an app development. It will start with setting up a Docker server and configuring Jenkins on it. It will then provide steps to build applications on Docker files and integrate them with Jenkins using continuous delivery processes such as continuous integration, automated acceptance testing, and configuration management. Moving on, you will learn how to ensure quick application deployment with Docker containers along with scaling Jenkins using Kubernetes. Next, you will get to know how to deploy applications using Docker images and testing them with Jenkins. Towards the end, the book will touch base with missing parts of the CD pipeline, which are the environments and infrastructure, application versioning, and nonfunctional testing. By the end of the book, you will be enhancing the DevOps workflow by integrating the functionalities of Docker and Jenkins.

Deployment with Ansible


We have covered the most fundamental features of Ansible. Now, let's forget, just for a little while, about Docker, Kubernetes, and most of the things we've learned so far. Let's configure a complete deployment step by only using Ansible. We will run the calculator service on one server and the Hazelcast service on the second server.

Installing Hazelcast

We can specify a play in the new playbook. Let's create the playbook.yml file, with the following content:

---
- hosts: web1
  become: yes
  become_method: sudo
  tasks:
  - name: ensure Java Runtime Environment is installed
    apt: 
      name: default-jre
      state: present
      update_cache: yes
  - name: create Hazelcast directory
    file:
      path: /var/hazelcast
      state: directory
  - name: download Hazelcast
    get_url:
      url: https://repo1.maven.org/maven2/com/hazelcast/hazelcast/3.12/hazelcast-3.12.jar
      dest: /var/hazelcast/hazelcast.jar
      mode: a+r
  - name: copy Hazelcast starting...
