In this blog post, I’m going to show you how to test Kubernetes locally on OSX/macOS. Testing Kubernetes without having access to a cloud operator in a local lab is not as easy as it sounds. I’d like to share some of my experiences in this adventure. For those who have already experienced in Virtualbox & Vagrant combination, I can tell you that it doesn’t work. Since Kubernetes will require virtualization, setting another virtual environment within another VirtualBox has several issues. After trying to bring up a cluster for a day or two, I gave up my traditional lab and figured out that Kubernetes has an alternate solution called minikube.

If your OSX/macOS doesn’t have brew I strongly recommend …

Containers are eating the world. If you have built and deployed an application in production over the last few years, the odds are that you have deployed your code in containers. You might have created and deployed individual containers (Docker, Linux LXC, etc.) directly in the beginning, but quickly switched over to a container orchestration technology like Kubernetes (K8s) or Swarm when you needed to coordinate multi-node deployments and high availability (HA). In this container-driven world, what will the future of the application stack look like? Let’s start with what we need from this “future” application stack.

What Do We Need From This Future Application Stack?

In the context of providing managed WordPress hosting services, at Presslabs we operate with lots of small to medium-sized databases, in a DB-per-service model, as we call it. The workloads are mostly reads, so we need to efficiently scale that. The MySQL® asynchronous replication model fits the bill very well, allowing us to scale horizontally from one server—with the obvious availability pitfalls—to tens of nodes. The next release of the stack is going to be open-sourced.

As we were already using Kubernetes, we were looking for an operator that could automate our DB deployments and auto-scaling. Those available were doing synchronous replication using MySQL group replication or Galera-based replication. Therefore, we decided to write our own operator.

Solution architecture

Without question, Kubernetes is the most popular container orchestration platform. But can it handle databases? I think so, and in this webinar, I will show you how it does it. This talk presents a quick overview of the persistent storage options (the most critical part of data storage) and then what it takes to run highly available MySQL …

Kubernetes, and its most popular distribution OpenShift, receives a lot of interest as a container orchestration platform. However, databases remain a foreign entity, primarily because of their stateful nature, since container orchestration systems prefer stateless applications. That said, there has been good progress in support for StatefulSet applications and persistent storage, to the extent that it might be already comfortable to have a production database instance running in Kubernetes. With this in mind, we’ve been looking at running Percona XtraDB Cluster in Kubernetes/OpenShift.

While there are already many examples on the Internet of how to start a single MySQL instance in Kubernetes, for serious usage we need to provide:

• High Availability: how can we guarantee availability …

Oracle Cloud Infrastructure (OCI) is Oracle’s second-generation cloud infrastructure. These new datacenters were built with the latest high-performance servers (Oracle’s X7 Servers) and were designed to eliminate network and CPU oversubscription. Due to high-performance systems and the multiple availability domains (ADs) in each region, these are the preferred environments for deploying MySQL. Since MySQL deploys on Compute services (IaaS), look for “Oracle Cloud Infrastructure Compute” (not Classic) on this region map.

Beyond the benefits of the second-generation datacenters, why deploy MySQL on Oracle’s cloud? Here’s a few of reasons people are choosing MySQL on OCI:

• No vendor lock-in: pay minimal or no egress charges and directly access your binary data files. Getting your data out of other clouds can be tedious and expensive. …

The website or mobile app is the storefront for participating in the modern digital era. It’s your portal for inviting users to come and survey your products and services. Much attention focuses on front-end development; this is where the HMTL5, CSS, and JavaScript are coded to develop the landing page that everyone sees when they visit your site.

But the real magic happens on the backend. This is the ecosystem that really powers your website. One writer has articulated this point very nicely as follows:

The technology and programming that “power” a site—what your end user doesn’t see but what makes the site run—is called the back end. Consisting of the server, the database, and the server-side applications, it’s the behind-the-scenes functionality—the brain of a site. …
