Configure load balancing, port forwarding, or setup firewall or DNS configurations to access applications in a cluster.

This page explains how to add versioning information to CustomResourceDefinitions, to indicate the stability level of your CustomResourceDefinitions or advance your API to a new version with conversion between API representations. It also describes how to upgrade an object from one version to another. Before you begin You need to have a Kubernetes cluster, and the kubectl command-line tool must be configured to communicate with your cluster. It is recommended to run this tutorial on a cluster with at least two nodes that are not acting as control plane hosts.

FEATURE STATE: Kubernetes v1.19 [stable] Seccomp stands for secure computing mode and has been a feature of the Linux kernel since version 2.6.12. It can be used to sandbox the privileges of a process, restricting the calls it is able to make from userspace into the kernel. Kubernetes lets you automatically apply seccomp profiles loaded onto a node to your Pods and containers. Identifying the privileges required for your workloads can be difficult.

Every node in a Kubernetes cluster runs a kube-proxy (unless you have deployed your own alternative component in place of kube-proxy). The kube-proxy component is responsible for implementing a virtual IP mechanism for Services of type other than ExternalName. Each instance of kube-proxy watches the Kubernetes control plane for the addition and removal of Service and EndpointSlice objects. For each Service, kube-proxy calls appropriate APIs (depending on the kube-proxy mode) to configure the node to capture traffic to the Service's clusterIP and port, and redirect that traffic to one of the Service's endpoints (usually a Pod, but possibly an arbitrary user-provided IP address).

Synopsis Set the latest last-applied-configuration annotations by setting it to match the contents of a file. This results in the last-applied-configuration being updated as though 'kubectl apply -f<file> ' was run, without updating any other parts of the object. kubectl apply set-last-applied -f FILENAME Examples # Set the last-applied-configuration of a resource to match the contents of a file kubectl apply set-last-applied -f deploy.yaml # Execute set-last-applied against each configuration file in a directory kubectl apply set-last-applied -f path/ # Set the last-applied-configuration of a resource to match the contents of a file; will create the annotation if it does not already exist kubectl apply set-last-applied -f deploy.

Package v1beta1 is the v1beta1 version of the external metrics API. Resource Types ExternalMetricValue ExternalMetricValueList ExternalMetricValue Appears in: ExternalMetricValueList ExternalMetricValue is a metric value for external metric A single metric value is identified by metric name and a set of string labels. For one metric there can be multiple values with different sets of labels. FieldDescription apiVersionstringexternal.metrics.k8s.io/v1beta1 kindstringExternalMetricValue metricName [Required] string the name of the metric metricLabels [Required] map[string]string a set of labels that identify a single time series for the metric

Overview Package v1beta4 defines the v1beta4 version of the kubeadm configuration file format. This version improves on the v1beta3 format by fixing some minor issues and adding a few new fields. A list of changes since v1beta3: v1.33: Add an EtcdUpgrade field to UpgradeConfiguration.plan that can be used to control whether the etcd upgrade plan should be displayed. v1.31: Support custom environment variables in control plane components under ClusterConfiguration. Use apiServer.

Resource Types CredentialProviderConfig CredentialProviderConfig CredentialProviderConfig is the configuration containing information about each exec credential provider. Kubelet reads this configuration from disk and enables each provider as specified by the CredentialProvider type. FieldDescription apiVersionstringkubelet.config.k8s.io/v1 kindstringCredentialProviderConfig providers [Required] []CredentialProvider providers is a list of credential provider plugins that will be enabled by the kubelet. Multiple providers may match against a single image, in which case credentials from all providers will be returned to the kubelet.
