Running Crunchydata Postgres on OpenStack Flex

Crunchydata provides a Postgres Operator that simplifies the deployment and management of PostgreSQL clusters on Kubernetes. In this guide, we will walk through deploying the Postgres Operator from Crunchy Data on an OpenStack Flex instance. As operators, we will need to create a new instance, install the Postgres Operator software, and configure the service to run on the instance. The intent of this guide is to provide a simple functional example of how to deploy the Postgres Operator from Crunchy Data on an OpenStack Flex on Kubernetes.

Running MetalLB on OpenStack Flex

MetalLb is a load balancer for Kubernetes that provides a network load balancer implementation for Kubernetes clusters. MetalLB is a Kubernetes controller that watches for services of type LoadBalancer and provides a network load balancer implementation. The load balancer implementation is based on standard routing protocols. In this post we'll setup a set of allowed address pairs on the OpenStack Flex network to allow MetalLB to assign floating IPs to the load balancer service.

Running CockroachDB on OpenStack Flex

CockroachDB is a distributed SQL database that provides consistency, fault-tolerance, and scalability that has been purpose built for the cloud. In this guide, we will walk through deploying CockroachDB on an OpenStack Flex instance. As operators, we will need to create a new instance, install the CockroachDB software, and configure the service to run on the instance. The intent of this guide is to provide a simple functional example of how to deploy CockroachDB on an OpenStack Flex on Kubernetes.

Running Longhorn on OpenStack Flex

Longhorn is a distributed block storage system for Kubernetes that is designed to be easy to deploy and manage. In this guide, we will walk through deploying Longhorn on an OpenStack Flex instance. As operators, we will need to create a new instance, install the Longhorn software, and configure the service to run on the instance. This setup will allow us to access the Longhorn web interface and create new volumes, snapshots, and backups. The intent of this guide is to provide a simple example of how to deploy Longhorn on an OpenStack Flex instance.

Running Talos on OpenStack Flex

As developers, we're constantly seeking platforms that streamline our workflows and enhance the performance and reliability of our applications. Talos is a container optimized Linux distribution reimagined for distributed systems. Designed with minimalism and practicality in mind, Talos brings a host of features that are particularly advantageous for OpenStack environments. By stripping away unnecessary components, it embodies minimalism, reducing the attack surface and resource consumption. It comes secure by default, providing out-of-the-box secure configurations that alleviate the need for extensive hardening.

Running Llama on Rackspace Cloud

In one of my favourite movie series The Avengers, Tony Stark (Iron Man) creates this Artificial Intelligence (AI) named Jarvis, which helps him make much of his other works possible. This portrayal sparks curiosity: Are such sophisticated AIs possible in real life? Until a few years ago, AI capabilities like JARVIS were confined to the realm of science fiction. However, advancements in AI have bridged the gap between fantasy and reality, making powerful, customizable AI models accessible to enthusiasts and professionals alike.

Running an Open Infrastructure Native Application

I recently decided I needed to run an application on OpenStack Flex to make things real. So naturally, I wrote an application from scratch that's more than just a boilerplate bucket of bolts. The gist of what I did over the weekend was to make a tool that harnesses the power of OpenStack with a Swift kick in the teeth.

Kustomize: Using environment variables for configuration

Kustomize is a widely used tool for Kuberenetes config management that provides a template free way to change your manifests during application deployment. It uses a kustomization.yaml file to define the actions taken during the build process. The file itself can be seen a collection of optional ordered processes: resources, generators, transformers, validators, configMapGenerator, patches and so on.

We wont dive too deep into these but look at a specific way of using the transformer property to use configuration values (as environment variables) from a file to drive your configuration.

Installing Github actions on a Openstack-Flex Instance

Introduction

Welcome! In this blog post we are going to go over connecting our Openstack-Flex instance to GitHub-actions through the use of self-hosted runners. We will be using an small Ubuntu image for our example, but if you would like a more in-depth look into setting up your environment please check out James’ blog post here.
