Introduction In this article, we will explore how to use Kubebuilder and Kind to create a local test cluster and an operator. Following that operation, we will then deploy that operator in the cluster and test it. All of the code is included below to port-forward to private endpoints the Kubernetes way. Also, if you want to learn more …

Cloud-native applications are dominating the market with their improved performance and high efficiency. While there are more resources to support cloud-native applications running as microservices, managing complex cloud architecture is still a challenge. The more microservices you run, the more tasks you will have to deal with in order to keep the cloud environment healthy …
Kubernetes is designed to support modular cloud-native applications from the ground up, so it is not surprising to find the platform to be equally modular and flexible. Kubernetes incorporates plugins, add-ons, services, and interfaces to extend the core functionalities of the platform. Kube’s integral configuration is how you can make changes and customize your environment, …

As apps become more complex in the way they use microservices, managing API keys and other secrets becomes more challenging as well. Microservices running in containers need to transfer secrets to allow them to communicate with each other. Each of those transfers as well as the secrets being exchanged needs to be secured properly for …
There are a lot of frameworks in app development, but not all of them are tailored for today’s cloud environment. Many of them lack modularity and flexibility; some don’t even leverage the benefits of using cloud computing. The 12-Factor application principles are designed specifically for modern, containerized cloud environments from the beginning. Each component is …
Kubernetes is incredibly popular largely thanks to its flexibility. It can also be deployed quickly thanks to its modularity. To maintain that modularity, however, you need to construct your cloud environment in a fluid and customizable way; that means making sure that ConfigMaps and Secrets are designed to be infrastructure agnostic. Secrets, in particular, are …

Modern applications rely on microservices to remain scalable and efficient. Kubernetes provides the perfect environment for microservices to exist and work together with the tools and features it offers. As each part of the application gets placed in a container, the system as a whole becomes more scalable. The use of microservices and containers also …
Until very recently, there was no official form of accreditation for working with Kubernetes. The Certified Kubernetes Administrator (CKA) program was designed by the Cloud Native Computing Foundation (CNCF), working in partnership with The Linux Foundation, to help advance usage the Kubernetes ecosystem. Google aligned itself with The Linux Foundation to form the Cloud Native …

Monitoring has always been a big part of solutions design. It is a continuous process of data collection about a system for the purpose of analyzing that system. Monitoring is usually done in an active way, with a tool pinging or probing a system in order to get responses. Those responses are then analyzed to …

Introduction In a previous article, we configured Vault with Consul on our cluster. Now, it’s time to go ahead and use it to provision secrets to our pods/applications. If you don’t remember the post or haven’t configured Vault yet, head to Getting Started with HashiCorp Vault on Kubernetes first. In this article, we will create an …
Secure, reliable, and observable. These three objectives are what systems engineers aim for when developing a solution, both from an infrastructure standpoint and from a service design perspective.
Introduction Vault security, stores, and tight control access to tokens, passwords, certificates, API keys, and other secrets are critical in modern computing. Hashicorp Vault allows you to overcome the challenges of safely storing all your app secrets so you don’t have to worry anymore about how to access, share, and use them. In this article, …

Several elements are crucial to an effective and efficient CI/CD workflow. A cloud-native app designed to take advantage of containers and other cloud-native features is certainly one of those elements. A capable cloud infrastructure with containers configured for maximum performance is another. To complete the set, you need cloud-native tools to manage the CI/CD workflow …
Part of our major project work at Caylent is introducing and migrating clients to new platforms away from legacy architecture and obsolete tech. A significant player in our suite of tools is, of course, Kubernetes as it lends itself to comprehensive customization right from the installation phase. Accordingly, we can tailor business-critical solutions to a …

Kubernetes has swiftly become the de facto standard platform for running containerized workloads. This is because Kubernetes gets a lot of things right straight out of the box, and deployment manifests for application releases can be one of them.
Cloud storage in a compartmentalized environment is always a dark horse. It can be the simplest part of constructing a system, but it also has the potential to become very complex once…
Kubernetes may be very popular as a development and deployment environment, but it is not exactly ‘perfect’. One of the components that developers need to pay particular attention to when using Kubernetes in a…
It’s hard to ignore Kubernetes nowadays when discussing container orchestration thanks to its robustness and comprehensive features. It is capable of supporting even the most complex apps and services…
As discussed in depth in line with their management here, ingresses connect external traffic to Kubernetes services, allowing the app you run in Kubernetes to be accessed by users. The ingress abstraction is also treated…
There are several ways to manage your cloud infrastructure in a DevOps environment. DevOps on its own is developed as an approach that encourages fast-flowing app development and IT teams to move from development to testing and release in a seamless way. Jenkins optimizes that flow of work through automation and the seamless integration of …
