Question: What is Security For Linux Nodes?

Answer: Security For Linux NodesThis page describes security considerations and best practices specific to the Linux operating system.Protection for Secret data on nodesOn Linux nodes, memory-backed volumes (such as secret volume mounts, or emptyDir with medium: Memory) are implemented with a tmpfs filesystem.If you have swap configured and use an older Linux kernel (or a current kernel and an unsupported configuration of Kubernetes), memory backed volumes can have data written to persistent storage.The Linux kernel officially supports the noswap option from version 6.3, therefore it is recommended the used kernel version is 6.3 or later, or supports the noswap option via a backport, if swap is enabled on the node.Read swap memory management for more info.

Question: What is Feature Gates?

Answer: Feature GatesThis page contains an overview of the various feature gates an administrator can specify on different Kubernetes components.See feature stages for an explanation of the stages for a feature.OverviewFeature gates are a set of key=value pairs that describe Kubernetes features. You can turn these features on or off using the --feature-gates command line flag on each Kubernetes component.Each Kubernetes component lets you enable or disable a set of feature gates that are relevant to that component. Use -h flag to see a full set of feature gates for all components. To set feature gates for a component, such as kubelet, use the --feature-gates flag assigned to a list of feature pairs:--feature-gates=...,GracefulNodeShutdown=true The following tables are a summary of the feature gates that you can set on different Kubernetes components.The "Since" column contains the Kubernetes release when a feature is introduced or its release stage is changed.The "Until" column, if not empty, contains the last Kubernetes release in which you can still use a feature gate.If a feature is in the Alpha or Beta state, you can find the feature listed in the Alpha/Beta feature gate table.If a feature is stable you can find all stages for that feature listed in the Graduated/Deprecated feature gate table.The Graduated/Deprecated feature gate table also lists deprecated and withdrawn features.Note:For a reference to old feature gates that are removed, please refer to feature gates removed.Feature gates for Alpha or Beta featuresFeature gates for features in Alpha or Beta statesFeatureDefaultStageSinceUntilAllowParsingUserUIDFromCertAuthfalseAlpha1.33–AllowUnsafeMalformedObjectDeletionfalseAlpha1.32–APIResponseCompressionfalseAlpha1.71.15APIResponseCompressiontrueBeta1.16–APIServerIdentityfalseAlpha1.201.25APIServerIdentitytrueBeta1.26–APIServingWithRoutinefalseAlpha1.30–CBORServingAndStoragefalseAlpha1.32–ClearingNominatedNodeNameAfterBindingfalseAlpha1.341.34CloudControllerManagerWebhookfalseAlpha1.27–ClusterTrustBundlefalseAlpha1.271.32ClusterTrustBundlefalseBeta1.33–ClusterTrustBundleProjectionfalseAlpha1.291.32ClusterTrustBundleProjectionfalseBeta1.33–ComponentFlagzfalseAlpha1.32–ComponentSLIsfalseAlpha1.261.26ComponentSLIstrueBeta1.27–ComponentStatuszfalseAlpha1.32–ConcurrentWatchObjectDecodefalseBeta1.31–ConsistentListFromCachefalseAlpha1.281.30ConsistentListFromCachetrueBeta1.31–ContainerCheckpointfalseAlpha1.251.29ContainerCheckpointtrueBeta1.30–ContainerRestartRulesfalseAlpha1.34–ContainerStopSignalsfalseAlpha1.33–ContextualLoggingfalseAlpha1.24–ContextualLoggingtrueBeta1.30–CoordinatedLeaderElectionfalseAlpha1.311.32CoordinatedLeaderElectionfalseBeta1.33–CPUManagerPolicyAlphaOptionsfalseAlpha1.23–CPUManagerPolicyBetaOptionstrueBeta1.23–CrossNamespaceVolumeDataSourcefalseAlpha1.26–CSIVolumeHealthfalseAlpha1.21–CustomCPUCFSQuotaPeriodfalseAlpha1.12–DeclarativeValidationtrueBeta1.33–DeclarativeValidationTakeoverfalseBeta1.33–DeploymentReplicaSetTerminating

Question: What is Hello Minikube?

Answer: Hello MinikubeThis tutorial shows you how to run a sample app on Kubernetes using minikube. The tutorial provides a container image that uses NGINX to echo back all the requests.ObjectivesDeploy a sample application to minikube.Run the app.View application logs.Before you beginThis tutorial assumes that you have already set up minikube. See Step 1 in minikube start for installation instructions.Note:Only execute the instructions in Step 1, Installation. The rest is covered on this page.You also need to install kubectl. See Install tools for installation instructions.Create a minikube clusterminikube start Open the DashboardOpen the Kubernetes dashboard. You can do this two different ways:Open a new terminal, and run:# Start a new terminal, and leave this running. minikube dashboard Now, switch back to the terminal where you ran minikube start.Note:The dashboard command enables the dashboard add-on and opens the proxy in the default web browser. You can create Kubernetes resources on the dashboard such as Deployment and Service.To find out how to avoid directly invoking the browser from the terminal and get a URL for the web dashboard, see the "URL copy and paste" tab.By default, the dashboard is only accessible from within the internal Kubernetes virtual network. The dashboard command creates a temporary proxy to make the dashboard accessible from outside the Kubernetes virtual network.To stop the proxy, run Ctrl+C to exit the process. After the command exits, the dashboard remains running in the Kubernetes cluster. You can run the dashboard command again to create another proxy to access the dashboard.If you don't want minikube to open a web browser for you, run the dashboard subcommand with the --url flag. minikube outputs a URL that you can open in the browser you prefer.Open a new terminal, and run:# Start a new terminal, and leave this running. minikube dashboard --url Now, you can use this URL and switch back to the terminal where you ran minikube start.Create a DeploymentA Kubernetes Pod is a group of one or more Containers, tied together for the purposes of administration and networking. The Pod in this tutorial has only one Container. A Kubernetes Deployment checks on the health of your Pod and restarts the Pod's Container if it terminates. Deployments are the recommended way to manage the creation and scaling of Pods.Use the kubectl create command to create a Deployment that manages a Pod. The Pod runs a Container based on the provided Docker image.# Run a test container image that includes a webserver kubectl create deployment hello-node --image=registry.k8s.io/e2e-test-images/agnhost:2.53 -- /agnhost netexec --http-port=8080 View the Deployment:kubectl get deployments The output is similar to:NAME READY UP-TO-DATE AVAILABLE AGE hello-node 1/1 1 1 1m (It may take some time for the pod to become available. If you see "0/1", try again in a few seconds.)View the Pod:kubectl get pods The output is similar to:NAME READY STATUS RESTARTS AGE
