This page shows how to perform a rolling update on a DaemonSet. 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. If you do not already have a cluster, you can create one by using minikube or you can use one of these Kubernetes playgrounds:

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.

Synopsis Apply a configuration to a resource by file name or stdin. The resource name must be specified. This resource will be created if it doesn't exist yet. To use 'apply', always create the resource initially with either 'apply' or 'create --save-config'. JSON and YAML formats are accepted. Alpha Disclaimer: the --prune functionality is not yet complete. Do not use unless you are aware of what the current state is.

Synopsis Copy files and directories to and from containers. kubectl cp <file-spec-src> <file-spec-dest> Examples # !!!Important Note!!! # Requires that the 'tar' binary is present in your container # image. If 'tar' is not present, 'kubectl cp' will fail. # # For advanced use cases, such as symlinks, wildcard expansion or # file mode preservation, consider using 'kubectl exec'. # Copy /tmp/foo local file to /tmp/bar in a remote pod in namespace <some-namespace> tar cf - /tmp/foo | kubectl exec -i -n <some-namespace> <some-pod> -- tar xf - -C /tmp/bar # Copy /tmp/foo from a remote pod to /tmp/bar locally kubectl exec -n <some-namespace> <some-pod> -- tar cf - /tmp/foo | tar xf - -C /tmp/bar # Copy /tmp/foo_dir local directory to /tmp/bar_dir in a remote pod in the default namespace kubectl cp /tmp/foo_dir <some-pod>:/tmp/bar_dir # Copy /tmp/foo local file to /tmp/bar in a remote pod in a specific container kubectl cp /tmp/foo <some-pod>:/tmp/bar -c <specific-container> # Copy /tmp/foo local file to /tmp/bar in a remote pod in namespace <some-namespace> kubectl cp /tmp/foo <some-namespace>/<some-pod>:/tmp/bar # Copy /tmp/foo from a remote pod to /tmp/bar locally kubectl cp <some-namespace>/<some-pod>:/tmp/foo /tmp/bar Options -c, --container string Container name.

Synopsis Renames a context from the kubeconfig file. CONTEXT_NAME is the context name that you want to change. NEW_NAME is the new name you want to set. Note: If the context being renamed is the 'current-context', this field will also be updated. kubectl config rename-context CONTEXT_NAME NEW_NAME Examples # Rename the context 'old-name' to 'new-name' in your kubeconfig file kubectl config rename-context old-name new-name Options -h, --help help for rename-context

Synopsis Delete the specified context from the kubeconfig. kubectl config delete-context NAME Examples # Delete the context for the minikube cluster kubectl config delete-context minikube Options -h, --help help for delete-context --as string Username to impersonate for the operation. User could be a regular user or a service account in a namespace. --as-group strings Group to impersonate for the operation, this flag can be repeated to specify multiple groups.

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

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.

This document shares how to validate IPv4/IPv6 dual-stack enabled Kubernetes clusters. Before you begin Provider support for dual-stack networking (Cloud provider or otherwise must be able to provide Kubernetes nodes with routable IPv4/IPv6 network interfaces) A network plugin that supports dual-stack networking. Dual-stack enabled cluster Your Kubernetes server must be at or later than version v1.23. To check the version, enter kubectl version. Note:While you can validate with an earlier version, the feature is only GA and officially supported since v1.

FEATURE STATE: Kubernetes v1.24 [stable] In this example, you will run a Kubernetes Job that uses multiple parallel worker processes. Each worker is a different container running in its own Pod. The Pods have an index number that the control plane sets automatically, which allows each Pod to identify which part of the overall task to work on. The pod index is available in the annotation batch.kubernetes.io/job-completion-index as a string representing its decimal value.
