The latest News and Information on Containers, Kubernetes, Docker and related technologies.
As developers, we need to get back to being diligent - and consistently diligent - about questions of security, provenance, reliability and availability when it comes to packages and dependencies.
Monitor Kubelet is key when running Kubernetes in production. Kubelet is a very important service inside Kubernetes’ control plane. It’s the component that cares that the containers described by pods are running in the nodes. Kubelet works in a declarative way by receiving PodSpecs and ensuring that the current state matches desired pods.
In this blog series, we’ll explore a few different ways that Rancher uses TLS certificates. TLS, or Transport Layer Security, is a cryptographic protocol used to secure network communication. It is the successor to the now-deprecated Secure Sockets Layer, or SSL. You can expect to walk away with an understanding of how TLS integrates into various Rancher components, and how you can prepare your environment to properly leverage TLS in Rancher.
We have made much of why we went with Rancher’s k3s to underpin Civo’s managed Kubernetes service in posts such as Andy’s explanation of k8s vs k3s, but I wanted to take a bit of a deeper dive into k3s and why in particular it is a great technological choice for a service such as ours.
Looking back over 2019 it's been a huge time of change for us as a company. When I co-founded Civo four years ago we were aiming to be an IaaS (Infrastructure-As-A-Service) provider, focusing on small developers and teams rather than huge corporate hosting requirements. The developer experience was really important to us, but trying to carve out a niche in such a crowded market was really challenging.
Experience Kubernetes OOM kills can be very frustrating. Why is my application struggling if I have plenty of CPU in the node? Managing Kubernetes pod resources can be a challenge. Many issues can arise, possibly due to an incorrect configuration of Kubernetes limits and requests. In this article, we will try to help you detect the most common issues related to the usage of resources.
When an application in a Docker container emits logs, they are sent to the application’s stdout and stderr output streams. The container’s logging driver can access these streams and send the logs to a file, a log collector running on the host, or a log management service endpoint. In this post, we’ll explain how the driver you choose—and how you configure it—influences the performance of your containerized application and the reliability of your Docker logging.
