To perform a diagnostic, the kubelet either executes code within the container or makes a network request. There are three types of probes in Kubernetes Liveness Probe indicates whether the container is running. Readiness Probe indicates whether the container is ready to respond to requests. Startup Probe indicates whether the container is started. Liveness Probe Link to heading The kubelet uses a liveness probe to know when to restart the container. http://www.viveksyngh.com/posts/running-highly-available-apps-on-kubernetes/ Wed, 11 May 2022 00:00:00 -0600 http://www.viveksyngh.com/posts/running-highly-available-apps-on-kubernetes/ As Kubernetes becomes the de-facto standard for deploying applications, many of us are either running our applications on Kubernetes or trying to migrate to Kubernetes. In this blog post, I will go through some tips for running highly available applications on Kubernetes. Kubernetes: Link to heading Kubernetes, also known as K8s, is an open-source system for automating the deployment, scaling, and management of containerized applications. It is designed on the same principles that allow Google to run billions of containers a week, Kubernetes can scale without increasing your ops team. http://www.viveksyngh.com/posts/linux-virtual-ethernet-devices/ Sat, 25 Sep 2021 00:00:00 -0600 http://www.viveksyngh.com/posts/linux-virtual-ethernet-devices/ Linux has rich virtual networking capabilities and in the series of posts, I am going to dig into these virtual networking interfaces, how to use them and what are their use cases. In this post, we will be looking into VETH (Virtual Ethernet) virtual networking interface. VETH devices are virtual ethernet devices. They can act as tunnels between network namespaces to create a bridge to a physical network device in another namespace, but can also be used as standalone network devices.
