Ironic
The Bare Metal service, codenamed ironic, is a collection of components that provides support to manage and provision physical machines. Bare Metal service components The Bare Metal service includes the following components: ironic-api A RESTful API that processes application requests by sending them to the ironic-conductor over remote procedure call (RPC). Can be run through WSGI or as a […]
Horizontal Pod Autoscaling in Kubernetes
In Kubernetes, a HorizontalPodAutoscaler automatically updates a workload resource (such as a Deployment or StatefulSet), with the aim of automatically scaling the workload to match demand. Horizontal scaling means deploying more Pods to respond to increased load. This is different from vertical scaling, which for Kubernetes would mean assigning more resources (for example: memory or CPU) to the Pods that are already […]
Getting Started with Ceilometer
The Telemetry Data Collection services provide the following functions: The Telemetry service consists of the following components:A compute agent (ceilometer-agent-compute) Runs on each compute node and polls for resource utilization statistics. This is actually the polling agent ceilometer-polling running with parameter –polling-namespace compute.A central agent (ceilometer-agent-central) Runs on a central management server to poll for resource utilization statistics for […]

Tekton Operator entities Tekton Operator defines the following entities: Entity Description TektonConfig Configure Tekton components to be installed and managed. TektonPipeline Configure the Tekton Pipeline component to be installed […]
Kubernetes Storage Classes
Storage Classes This document describes the concept of a StorageClass in Kubernetes. Familiarity with volumes and persistent volumes is suggested. A StorageClass provides a way for administrators to describe the classes of storage they offer. Different classes might map to quality-of-service levels, or to backup policies, or to arbitrary policies determined by the cluster administrators. Kubernetes itself is unopinionated about what […]
Kubernetes Taints and Tolerations
Node affinity is a property of Pods that attracts them to a set of nodes (either as a preference or a hard requirement). Taints are the opposite — they allow a node to repel a set of pods. Tolerations are applied to pods. Tolerations allow the scheduler to schedule pods with matching taints. Tolerations allow scheduling but don’t guarantee scheduling: the scheduler also evaluates other parameters as […]
Kubernetes DNS Pod Service
DNS for Services and Pods Kubernetes creates DNS records for Services and Pods. You can contact Services with consistent DNS names instead of IP addresses. Kubernetes publishes information about Pods and Services which is used to program DNS. Kubelet configures Pods’ DNS so that running containers can lookup Services by name rather than IP. Services […]
iDRAC Driver
Overview The integrated Dell Remote Access Controller (iDRAC) is an out-of-band management platform on Dell EMC servers, and is supported directly by the idrac hardware type. This driver uses the Dell Web Services for Management (WSMAN) protocol and the standard Distributed Management Task Force (DMTF) Redfish protocol to perform all of its functions. iDRAC hardware is also supported […]
ArtifactHub Repositories
Artifact Hub allows publishers to list their content in an automated way. Publishers can add their repositories from the control panel, accessible from the top right menu after signing in. It’s possible to create an organization and add repositories to it instead of adding them to the user’s account. Repositories will be indexed periodically to […]
