PKC Complete Installation Process

Introduction

This page is written to give complete documentation on how the PKC is installed, description of all the related services, and the concept behind the architecture design. PKC Architecture is implemented at several docker container that runs its own service on same virtual network. PKC can be installed on a Virtual Machine or Bare-Metal machine.

Docker Concept

Docker is an containerized application runs on top of host operating system. It is some form of more lightweight implementation of virtualization. All we need to do to deploy and shipped new application is to containerized all our executable code and all its dependencies inside one docker container, and we are ready to delivered the application.

• Docker is a tools, to develop and run container
• Container is the packed executable and application code.

In order to run container, we need some kind of tools, which in this case are using Docker. For further readings, please visit this page for comprehensive explanation of Docker by Bibin Wilson.
Below is the simple diagram on how container is deployed into one's computer, to give better understanding on high-level concept of docker container.

Simple diagram on How Docker is Deployed

On host Operating System, administrator only need to install and configured Docker or other software with the capability to run container, and installed all the application container within the operating system. Them all the service will be ready to go without need to install all the code and dependecies.

Ansible Concept

Ansible is open-source tools that provide automation tools for cross-platform computer support. Enabled developer or DevOps to perform various task of installation, configuration, and provisioning computer and/or server. Basically everything that system administrator does in routine. And it does not depend on any agent software nor additional security layers. So its easy to use and deploy. Below are the simple schematic diagram to better give high-level understanding of ansible.

Simple diagram on How Ansible is Work

The Ansile script, only need to be deployed on one ansible agent with connection to the servers. Then the task that has already defined in ansible agent will be executed on target computer and/or server.

PKC Architecture Review

Please find below are the diagram of PKC Implementation on micro-services and containerization.

PKC Implementation Overview

PKC consist of below containers

1. XLP_Mediawiki: Mediawiki service, this is where all the content of XLP can be accessed, and the entrypoint for the implementation.
2. XLP_Gitea: Gitea service, for storing files and source-code.
3. XLP_Keycloak: Identity service provider for managing users
4. XLP_Matomo: Web Analytic Service, to monitor the usage and
5. XLP_VS: Web-Based Visual Studio Code, to manage source-code.
6. phpmyadmin: Tools for managing the databaser server.
7. XLP_MariaDB: mySQL RDBMS Provider
8. NGINX: Installed on host server, to manage the connectivity between incoming traffic and microservices.

All the binds folder is under the folder of $HOME/cs/mountpoint, below are the list of folder bind into containers

Folder/Filename	Container	Container's Folder
backup_restore/mariadb	xlp_mariadb	/mnt/backup_restore/mariadb
backup_restore/mediawiki	xlp_mediawiki	/mnt/backup_restore/mediawiki
gitea	gitea	/data
images	xlp_mediawiki	/var/www/html/images
LocalSettings.php	xlp_mediawiki	/var/www/html/LocalSettings.php
mariadb	xlp_mariadb	/var/lib/mysql
matomo	xlp_matomo	/bitnami/matomo
vs	xlp_vs	/config
mysql-init	xlp_mariadb	/docker-entrypoint-initdb.d

NGINX Configuration is stored on host folder /etc/nginx/sites-enabled, which forward traffic from outside into each container's port. below are the table of default PKC Configurations.

Container	Port#	Subdomain	Remarks
xlp_mariadb	N/A	N/A	Not exposed
phpmyadmin	32040	pma
xlp_keycloak	32060	kck
xlp_matomo	32010	mtm
xlp_mediawiki	32001	[Default]
xlp_gitea	32030	git
xlp_vs	32050	code

Pre-Requisite

PKC can be installed on fresh-installation of Ubuntu Linux 20.08 or Ubuntu Linux 18.04 minimal server setup. There's no specific software that needs to be installed beforehand. However, there are several items that needs to be configured before we can start the ansible script to setup PKC

How to provision your server

Below are the items that need to be properly setup before we can run the ansible installation script.

DNS Configuration

To enable the https:/ protocols, you will need to setup or procure domain name to point to your server's or VM's Public IP. Below are the default and subdomain configuration to setup.

Subdomain
[default] / www	Your Public IP
pma
kck
mtm
git
code

Provide Passwordless Access

To enable ssh passwordless access, you will need to enable the private key/public key method, this is required to run the automated ansible script. On some cloud provider such as AWS or Google Cloud, the only way to access the ssh is through public key/private key method. In such case, you can directly use the provided private key. To execute the process please refer to How to create passwordless access page.

Installation Execution

This section will provide the required step to install the PKC Infrastruction on your selected server. This process assuming that you already completed all the necessary pre-requisite above in advance.

Source Code

To clone the specific ansible script for this PKC installation, you need change to your chosen folde and clone git repository with branch [dev], with below command:

git clone -b dev https://github.com/xlp0/PKC.git

This command will create new folder called PKC inside the folder, then change to PKC folder by executing change folder command

cd PKC
