Description

This file is an clarifying note for using the "install" software product. This product is a system for automatic deployment of cloud infrastructure, the main task of which is to install Liferay and integrate it with PostgreSQL from Jenkins and Ansible in Microsoft Azure.

The main tasks solved by the product

1. Testing software products in environments: postgreSQL, Jenkins, Liferay (for Testers)
2. To get a ready-made server solution (for system administrators)
3. Creating a simple workspace for generalists (developers, datascientists)
4. For educational and educational tasks (for instructors, lectures, direction curators, timeleads)

Tasks performed:

1. Makes "update" of the main OS repository
2. Install Python3 and PIP required to start the deployment process
3. Install software components terraform, ansible, azurecli - necessary to automate the process of deploying infrastructure
4. Generates ansible inventory file, depending on the characteristics of the deployment VMs
5. Connects ansible-vars and ansible-roles for automatization deployment of the server component.
6. Establishes connection, basic setup, preparation for using postgreSQL, Jenkins, Liferay servers

Basic ansible functions:

• Install TomcatXJenkins and setup Jenkins and run PostgreSQL-Liferay-Wildfly deploy pipeline
• Jenkins pipline:
  • Install postgreSQL server:
    • Configuring postgreSQL
    • Creating psql role
• Install liferay+wildfly-bundle and configures Liferay:
  • Downloading postgres.jar and adding liferay config

To get to at the output:

• Complete Tomcat-Jenkins server, basic Jenkins setup, starting the postgresql-liferay-wildfly deployment process
• Installation and basic configuration of the postgreSQL server, creating the psql role
• Install liferay + wildfly-bundle, basic Liferay setup:
• Downloaded postgres.jar file, adding liferay config

Authenticating in Azure using client secrtet

Create the Service Principal which will have permissions to manage resources in the specified Subscription using the following command:

 az ad sp create-for-rbac --role="Contributor" --scopes="/subscriptions/SUBSCRIPTION_ID"

output:

{
  "appId": "00000000-0000-0000-0000-000000000000",
  "displayName": "azure-cli-2017-06-05-10-41-15",
  "name": "http://azure-cli-2017-06-05-10-41-15",
  "password": "0000-0000-0000-0000-000000000000",
  "tenant": "00000000-0000-0000-0000-000000000000"
}

These values map to the Terraform variables like so:

• appId is the client_id defined above.
• password is the client_secret defined above.
• tenant is the tenant_id defined above.

Running on the host

Export Azure credentials

$ export ARM_CLIENT_ID="00000000-0000-0000-0000-000000000000"
$ export ARM_CLIENT_SECRET="00000000-0000-0000-0000-000000000000"
$ export ARM_SUBSCRIPTION_ID="00000000-0000-0000-0000-000000000000"
$ export ARM_TENANT_ID="00000000-0000-0000-0000-000000000000"

Go to netcracker_edu_project directory and use the command

./install.sh -e [e-mail for Liferay]

Overview

install.sh

Install python3 and other dependencies.

#!/bin/bash

sudo yum update 
sudo yum install -y python3
sudo yum install -y python3-pip
pip3 install --upgrade pip
pip3 install -r requirements.txt
python3 demo.py $@

demo.py

Install all requirements, generates inventory files and ansible variables file, runs ansible-playbook.

Try --help to see which components can be set manually

python3 demo.py --help

terraform_azure.tf

Basic terraform functions:

• Creating resource group
• Configuring virtual network (public\private)
• Create security group
• Create 3 virtual machines in Microsoft Azure:
  • 2 virtual machines - Standard_D1_v2
  • 1 virtual machine - Standard_D2as_v4
