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

Synopsis Mark node as unschedulable. kubectl cordon NODE Examples # Mark node "foo" as unschedulable kubectl cordon foo Options --dry-run string[="unchanged"]     Default: "none" Must be "none", "server", or "client". If client strategy, only print the object that would be sent, without sending it. If server strategy, submit server-side request without persisting the resource. -h, --help help for cordon -l, --selector string Selector (label query) to filter on, supports '=', '==', and '!

Synopsis Create an ingress with the specified name. kubectl create ingress NAME --rule=host/path=service:port[,tls[=secret]] Examples # Create a single ingress called 'simple' that directs requests to foo.com/bar to svc # svc1:8080 with a TLS secret "my-cert" kubectl create ingress simple --rule="foo.com/bar=svc1:8080,tls=my-cert" # Create a catch all ingress of "/path" pointing to service svc:port and Ingress Class as "otheringress" kubectl create ingress catch-all --class=otheringress --rule="/path=svc:port" # Create an ingress with two annotations: ingress.

Synopsis Create a namespace with the specified name. kubectl create namespace NAME [--dry-run=server|client|none] Examples # Create a new namespace named my-namespace kubectl create namespace my-namespace Options --allow-missing-template-keys     Default: true If true, ignore any errors in templates when a field or map key is missing in the template. Only applies to golang and jsonpath output formats. --dry-run string[="unchanged"]     Default: "none" Must be "none", "server", or "client".

API Priority and Fairness controls the behavior of the Kubernetes API server in an overload situation. You can find more information about it in the API Priority and Fairness documentation. Diagnostics Every HTTP response from an API server with the priority and fairness feature enabled has two extra headers: X-Kubernetes-PF-FlowSchema-UID and X-Kubernetes-PF-PriorityLevel-UID, noting the flow schema that matched the request and the priority level to which it was assigned, respectively.

Kustomize is a standalone tool to customize Kubernetes objects through a kustomization file. Since 1.14, Kubectl also supports the management of Kubernetes objects using a kustomization file. To view Resources found in a directory containing a kustomization file, run the following command: kubectl kustomize <kustomization_directory> To apply those Resources, run kubectl apply with --kustomize or -k flag: kubectl apply -k <kustomization_directory> Before you begin Install kubectl. You need to have a Kubernetes cluster, and the kubectl command-line tool must be configured to communicate with your cluster.

This guide is to help users debug applications that are deployed into Kubernetes and not behaving correctly. This is not a guide for people who want to debug their cluster. For that you should check out this guide. Diagnosing the problem The first step in troubleshooting is triage. What is the problem? Is it your Pods, your Replication Controller or your Service? Debugging Pods Debugging Replication Controllers Debugging Services Debugging Pods The first step in debugging a Pod is taking a look at it.

This page shows how to define environment variables for a container in a Kubernetes Pod. 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:

Attribute-based access control (ABAC) defines an access control paradigm whereby access rights are granted to users through the use of policies which combine attributes together. Policy File Format To enable ABAC mode, specify --authorization-policy-file=SOME_FILENAME and --authorization-mode=ABAC on startup. The file format is one JSON object per line. There should be no enclosing list or map, only one map per line. Each line is a "policy object", where each such object is a map with the following properties:
