Dockerizing MySQL step by step.

As a Database Engineer in Mydbops. We tend to solve multiple complex problems for our esteemed customers. To control the System resources and scale up /down based on needed we are evaluating Dockers and Kubernetes.

Docker is a set of platform as a service products that uses OS-level virtualization to deliver software in packages called Containers. Containers are isolated from one another and bundle their own software, libraries and configuration files; they can communicate with each other through well-defined channels.It’s more lightweight than standard Containers and boots up in seconds.

Docker also is easy to use when you need a simple, single instance. What is great about Docker though is that it allows configuring multiple versions of MySQL.

A Linux Tool to Monitor Progress of MySQL Data Imports and Exports.

One problem I have experienced during logical exporting and importing databases is the tools don’t output any progress indicator (or anything at all really) and using the -v (verbose) switch outputs every single MySQL command being run from the import file. As, importing and exporting of databases  is one of the most frequent activity being performed , I Just felt the need of some tool that could help me check the approximate progress of import and export of databases going on.

So, I searched and fortunately could find a tool named Pipeviewer (PV) which allows a user to see the progress of data through a pipeline, by giving information such as time elapsed, percentage completed (with progress bar), current throughput rate, total data transferred, and ETA .

Installation :

On Centos and RHEL :

[root@vm1 vagrant]# yum install pv

[root@vm1 …
