Red Hat open source databases in beta: Adds PostgreSQL 10, MongoDB 3.6; updates MySQL 5.7

By Mike Guerette

Twice a year, Red Hat distributes new versions of compiler toolsets, scripting languages, open source databases, and/or web tools, etc. so that application developers will have access to the latest, stable versions. These Red Hat supported offerings are packaged as Red Hat Software Collections (scripting languages, open source databases, web tools, etc.), Red Hat Developer Toolset (GCC), and the recently added compiler toolsets Clang/LLVM, Go, and Rust. All are yum installable, and are included in most Red Hat Enterprise Linux subscriptions and all Red Hat Enterprise Linux Developer Subscriptions. Most Red Hat Software Collections and Red Hat Developer Toolset components are also available as Linux container images for hybrid cloud development across Red Hat Enterprise Linux, Red Hat OpenShift Container Platform, etc.

Red Hat Software Collections 3.1 beta brings the following new/updated open source databases:

Deploying a Spring Boot App with MySQL on OpenShift

cpandeyredhat-com
By Chandra Shekhar Pandey

This article shows how to take an existing Spring Boot standalone project that uses MySQL and deploy it on Red Hat OpenShift,  In the process, we’ll create docker images which can be deployed to most container/cloud platforms. I’ll discuss creating a Dockerfile, pushing the container image to an OpenShift registry, and finally creating running pods with the Spring Boot app deployed.

To develop and test using OpenShift on my local machine, I used Red Hat Container Development Kit (CDK), which provides a single-node OpenShift cluster running in a Red Hat Enterprise Linux VM, based on minishift. You can run CDK on top of Windows, macOS, or Red Hat Enterprise Linux.   For testing, I used Red Hat Enterprise Linux Workstation release 7.3. It should work on macOS too.

To create the Spring Boot app I used this article as a guide. I’m using an existing openshift/mysql-56-centos7 docker image to deploy MySQL to  OpenShift.

Red Hat JBoss Data Virtualization on OpenShift: Part 3 – Data federation

cvanball
By Cojan van Ballegooijen

Welcome to part 3 of Red Hat JBoss Data Virtualization (JDV) running on OpenShift.

JDV is a lean, virtual data integration solution that unlocks trapped data and delivers it as easily consumable, unified, and actionable information. JDV makes data spread across physically diverse systems such as multiple databases, XML files, and Hadoop systems appear as a set of tables in a local database.

When deployed on OpenShift, JDV enables:

  1. Service enabling your data
  2. Bringing data from outside to inside the PaaS
  3. Breaking up monolithic data sources virtually for a microservices architecture

Together with the JDV for OpenShift image, we have made available several OpenShift templates that allow you to test and bootstrap JDV.

Unlock your MariaDB/MySQL data with Red Hat JBoss Data Virtualization

mcoulib
By Madou Coulibaly

Welcome back to a new episode of the series: “Unlock your [….] data with Red Hat JBoss Data Virtualization.” Through this blog series, we will look at how to connect Red Hat JBoss Data Virtualization (JDV) to different and heterogenous data sources.

JDV is a lean, virtual data integration solution that unlocks trapped data and delivers it as easily consumable, unified, and actionable information. It makes data spread across physically diverse systems — such as multiple databases, XML files, and Hadoop systems — appear as a set of tables in a local database. By providing following functionality, JDV enables agile data use:

  1. Connect: Access data from multiple, heterogeneous data sources.
  2. Compose: Easily combine and transform data into reusable, business-friendly virtual data models and views.
  3. Consume: Make unified data easily consumable through open standards interfaces.

It hides complexities, like the true locations of data or the mechanisms required to access or merge it. Data becomes easier for developers and users to work with.

This post will guide you step-by-step how to connect JDV to a MariaDB/MySQL database using Teiid Designer. We will connect to a MariaDB 10.1 server using MySQL Connector/J 5.1, a JDBC driver for communicating with MariaDB/MySQL servers. Indeed, you can follow this same tutorial with a MySQL instance.

Cockpit: Your entrypoint to the Containers Management World

aarrichi
By Alessandro Arrichiello

Containers are one of the top trend today. Starting working or playing with them could be really hard also if you’ve well understood the theory at their base.

With this article I’ll try to show you some useful tips and tricks to start into containers world, thanks also to the great web interface provided by the Cockpit project.

Cockpit overview

Cockpit is an interactive server admin interface.  You’ll find below some a of its great features:

  • Cockpit comes “out of the box” ready for the admin to interact with the system immediately, without installing stuff, configuring access controls, making choices, etc.
  • Cockpit has (as near as makes no difference) zero memory and process footprint on the server when not in use. The job of a server is not to show a pretty UI to admins, but to serve stuff to others. Cockpit starts on demand via socket activation and exits when not in use.
  • Cockpit does not take over your server in such a way that you can then only perform further configuration in Cockpit.
  • Cockpit itself does not have a predefined template or state for the server that it then imposes on the server. It is imperative configuration rather than declarative configuration.
  • Cockpit dynamically updates itself to reflect the current state of the server, within a time frame of a few seconds.
  • Cockpit is firewall friendly: it opens one port for browser connections: by default that is 9090.
  • Cockpit can look different on different operating systems, because it’s the UI for the OS, and not a external tool.
  • Cockpit is pluggable: it allows others to add additional UI pieces.

Setting up a LAMP stack on Red Hat Enterprise Linux

By Keith Rogers

You obviously know what a LAMP stack is if you’ve managed to find your way here, but for those who may be unsure, the key is in the name (L)inux (A)pache (M)ariaDB (P)HP—a term that has become synonymous around the globe for building a basic web server with database and PHP functionality. There are a myriad of web applications, ranging from WordPress to Joomla to Magento that all use this setup, and if you know how to get it up and running, then you’re off to a great start. It couldn’t be easier with RHEL, so let’s get started. MariaDB can also be exchanged for MySQL or a database of your choice.

By Marek Skalický

“As a part of the Red Hat Software Collections offering, Red Hat provides a number of container images, which are based on the corresponding Software Collections. These include application, daemon, and database images. The provided images, currently available in the Beta version” (for more information see https://access.redhat.com/articles/1752723)

Red Hat Software Collections allows you to run newer versions of software on a stable Red Hat Enterprise Linux. These new images combine this feature with the benefits of containers.

In this post I would like to show you how to run database server from RHSCL in one command.
