Project goal:

• Automatic deployment of Dockerized Application with basic monitoring.
• Automatically collected metrics from containers via Prometheus (exporters) and cAdvisor.
• Visualization of metrics using Grafana platform.

Used tools: Vagrant, Virtual Box, Ansible, Docker, Prometheus, Grafana, cadvisor, Node_exporter

Use cases

TO DO

---

Prerequisites:

You must have installed:

1. Vagrant tool made by Hashi Corp
2. Virtual Box
3. Ansible
4. Mail account

• Vagrant is a tool for building and managing virtual machine environments in a single workflow. With an easy-to-use workflow and focus on automation, Vagrant lowers development environment setup time, increases production parity, and makes the "works on my machine" excuse a relic of the past.

• VirtualBox is a powerful x86 and AMD64/Intel64 virtualization product for enterprise as well as home use.

• Ansible is an IT automation tool. It can configure systems, deploy software, and orchestrate more advanced IT tasks such as continuous deployments or zero downtime rolling updates.

Instalation:

1. mkdir /your_path/project01
2. cd /your_path/project01
3. git init
4. git clone https://github.com/doriandinhxuan/Ghost-Application-with-basic-monitoring.git
5. cd host-Application-with-basic-monitoring
6. vagrant up

Access to Grafana Interface :

Username	Password	Port
admin	test!!	3000

Access to individual servers: vagrant ssh "name of machine" eg. vagrant ssh grafana

Check status of machine: vagrant status

All components will automatically deploy like: servers, os, application, and configuration. Important: Configuration of Grafana - DATASOURCES, DASHBORD will be also implemented.

Target configuration:

The environment consists of 3 virtual machines:

• 1 - server with installed and configured: Prometheus with Node_exporter.
• 1 - server with installed and configured: Grafana with Node_exporter.
• 1 - server with installed and configured: Docker, Ghost application, Node_exporter and cAdvisor.

The assumption of the project is a collection of all metrics from the Machines and docker containers.

Infrastructure diagram:

Components:

• Grafana - [ 192.168.10.101:3000 ]

• Prometheus -[ 192.168.10.102:9090 ]

• Ghost Blog - [ 192.168.10.103 ]

• cAdvisor Interface - [ 192.168.10.103:8080 ]

Before you run vagrant up

What do you have to do?

1. go to /your_path/project01/ghost-app-basic-monitoring/roles/ghostApp/files
2. Edit config.production.json
3. Put your email and password

voilà!

Now you can run vagrant up

config.production.json :

  "url": "http://192.168.10.103:80/",
  "server": {
    "port": 2368,
    "host": "0.0.0.0"
  },
  "database": {
    "client": "mysql",
    "connection": {
      "host": "127.0.0.1",
      "user": "root",
      "password": "ghost",
      "database": "ghost",
      "port": 3306
    }
  },
  "mail": {
    "transport": "SMTP",
    "options": {
    "service": "Gmail",
    "auth": {
    "user": "<your_mail@gmail.com>",
    "pass": "<your_password>"
      }
    }
  },
  "logging": {
    "level": "info",
      "rotation": {
          "enabled": true
      },
    "transports": [
      "file",
      "stdout"
    ]
},
"process": "systemd",
"paths": {
"contentPath": "/var/lib/ghost/content"
}
}

To automatic provision & deploy we are using ANSIBLE which is a radically simple IT automation engine that automates cloud provisioning, configuration management, application deployment, intra-service orchestration, and many other IT needs.
