NextCloud Talk Bot Custom Commands

Travis Docker, Linux, Media, Networking, Operating Systems, Shell, Storage NextCloud 0

The Talk add-on allows returning information when the user invokes a command preceded with a forward-slash.
I have created 3 custom commands that help NextCloud admins know certain server information that would otherwise have to come from other tools ie: monitoring/graphing software:

1. Disk space used, available, and percent used via df utility
2. Latency related info via common ping utility (install if not exists for you, normally net-utils pkg or similar)
3. Listing server-side mounts via standard mount command

Working of Docker in VM Based IT World-What Do You Need To Know

Travis DevOps, Docker, Linux, Virtualization, Windows Docker 0

Ecommerce development or magento development works for the transformations needed in the IT world. Docker is the most popular and used container platform. Virtual machines (VMs) are increasingly used by businesses. A VM is an operating system or application environment installed on software. It allows the user to enjoy the same experience as on a physical machine, with several advantages. In particular, it is possible to run multiple OS environments on the same machine, isolating them from each other. Similarly, virtualization can reduce costs within a business by reducing the number of virtual machines required. Energy needs are also reduced.

How to Migrate WordPress Nginx with Docker Compose on Ubuntu Xenial 16.04

Travis DevOps, Docker, Linux, NGINX, Operating Systems, Shell, Virtualization, WordPress Containers 0

This guide will explain how to migrate and dockerize an existing WordPress installation without running Apache. Most other tutorials I’ve seen combine multiple services inside of one container, while this article tries to maintain the standard of one service per container for easier isolation, troubleshooting, performance, and scale-out. This consists of configuring multiple Docker containers with docker-compose on Ubuntu 16.04 Xenial to run MariaDB 10.0.31 or MySQL, Nginx 1.13, PHP7.1-FPM and WordPress 4.8. There are many tutorials for creating new WordPress sites with Docker containers such as this one, however there aren’t many for those who already have a site and want to migrate existing

The Open Guide to Amazon Web Services

Travis AWS, DevOps, EC2, Networking, Route 53, SES, Storage, Virtualization, VPC 2

Why an Open Guide?
A lot of information on AWS is already written. Most people learn AWS by reading a blog or a “getting started guide” and referring to the standard AWS references. Nonetheless, trustworthy and practical information and recommendations aren’t easy to come by. AWS’s own documentation is a great but sprawling resource few have time to read fully, and it doesn’t include anything but official facts, so omits experiences of engineers. The information in blogs or Stack Overflow is also not consistently up to date.
This guide is by and for engineers who use AWS. It aims to be a useful, living reference that consolidates links, tips, gotchas, and best practices. It arose from discussion and editing over beers by several engineers who have used AWS extensively.
