Question: What is Advanced contributing?

Answer: Advanced contributingThis page assumes that you understand how to contribute to new content and review others' work, and are ready to learn about more ways to contribute. You need to use the Git command line client and other tools for some of these tasks.Propose improvementsSIG Docs members can propose improvements.After you've been contributing to the Kubernetes documentation for a while, you may have ideas for improving the Style Guide , the Content Guide, the toolchain used to build the documentation, the website style, the processes for reviewing and merging pull requests, or other aspects of the documentation. For maximum transparency, these types of proposals need to be discussed in a SIG Docs meeting or on the kubernetes-sig-docs mailing list. In addition, it can help to have some context about the way things currently work and why past decisions have been made before proposing sweeping changes. The quickest way to get answers to questions about how the documentation currently works is to ask in the #sig-docs Slack channel on kubernetes.slack.comAfter the discussion has taken place and the SIG is in agreement about the desired outcome, you can work on the proposed changes in the way that is the most appropriate. For instance, an update to the style guide or the website's functionality might involve opening a pull request, while a change related to documentation testing might involve working with sig-testing.Coordinate docs for a Kubernetes releaseSIG Docs approvers can coordinate docs for a Kubernetes release.Each Kubernetes release is coordinated by a team of people participating in the sig-release Special Interest Group (SIG). Others on the release team for a given release include an overall release lead, as well as representatives from sig-testing and others. To find out more about Kubernetes release processes, refer to https://github.com/kubernetes/sig-release.The SIG Docs representative for a given release coordinates the following tasks:Monitor the feature-tracking spreadsheet for new or changed features with an impact on documentation. If the documentation for a given feature won't be ready for the release, the feature may not be allowed to go into the release.Attend sig-release meetings regularly and give updates on the status of the docs for the release.Review and copyedit feature documentation drafted by the SIG responsible for implementing the feature.Merge release-related pull requests and maintain the Git feature branch for the release.Mentor other SIG Docs contributors who want to learn how to do this role in the future. This is known as "shadowing".Publish the documentation changes related to the release when the release artifacts are published.Coordinating a release is typically a 3-4 month commitment, and the duty is rotated among SIG Docs approvers.Serve as a New Contributor AmbassadorSIG Docs approvers can serve as New Contributor Ambassadors.New Contributor Ambassadors welcome new contributors to SIG-Docs, suggest PRs t

Question: What is Kubelet authentication/authorization?

Answer: Kubelet authentication/authorizationOverviewA kubelet's HTTPS endpoint exposes APIs which give access to data of varying sensitivity, and allow you to perform operations with varying levels of power on the node and within containers.This document describes how to authenticate and authorize access to the kubelet's HTTPS endpoint.Kubelet authenticationBy default, requests to the kubelet's HTTPS endpoint that are not rejected by other configured authentication methods are treated as anonymous requests, and given a username of system:anonymous and a group of system:unauthenticated.To disable anonymous access and send 401 Unauthorized responses to unauthenticated requests:start the kubelet with the --anonymous-auth=false flagTo enable X509 client certificate authentication to the kubelet's HTTPS endpoint:start the kubelet with the --client-ca-file flag, providing a CA bundle to verify client certificates withstart the apiserver with --kubelet-client-certificate and --kubelet-client-key flagssee the apiserver authentication documentation for more detailsTo enable API bearer tokens (including service account tokens) to be used to authenticate to the kubelet's HTTPS endpoint:ensure the authentication.k8s.io/v1beta1 API group is enabled in the API serverstart the kubelet with the --authentication-token-webhook and --kubeconfig flagsthe kubelet calls the TokenReview API on the configured API server to determine user information from bearer tokensKubelet authorizationAny request that is successfully authenticated (including an anonymous request) is then authorized. The default authorization mode is AlwaysAllow, which allows all requests.There are many possible reasons to subdivide access to the kubelet API:anonymous auth is enabled, but anonymous users' ability to call the kubelet API should be limitedbearer token auth is enabled, but arbitrary API users' (like service accounts) ability to call the kubelet API should be limitedclient certificate auth is enabled, but only some of the client certificates signed by the configured CA should be allowed to use the kubelet APITo subdivide access to the kubelet API, delegate authorization to the API server:ensure the authorization.k8s.io/v1beta1 API group is enabled in the API serverstart the kubelet with the --authorization-mode=Webhook and the --kubeconfig flagsthe kubelet calls the SubjectAccessReview API on the configured API server to determine whether each request is authorizedThe kubelet authorizes API requests using the same request attributes approach as the apiserver.The verb is determined from the incoming request's HTTP verb:HTTP verbrequest verbPOSTcreateGET, HEADgetPUTupdatePATCHpatchDELETEdeleteThe resource and subresource is determined from the incoming request's path:Kubelet APIresourcesubresource/stats/*nodesstats/metrics/*nodesmetrics/logs/*nodeslog/spec/*nodesspec/checkpoint/*nodescheckpointall othersnodesproxyThe namespace and API group attributes are always an empty string, and the resource na

Question: What is Kubelet Configuration Directory Merging?

Answer: Kubelet Configuration Directory MergingWhen using the kubelet's --config-dir flag to specify a drop-in directory for configuration, there is some specific behavior on how different types are merged.Here are some examples of how different data types behave during configuration merging:Structure FieldsThere are two types of structure fields in a YAML structure: singular (or a scalar type) and embedded (structures that contain scalar types). The configuration merging process handles the overriding of singular and embedded struct fields to create a resulting kubelet configuration.For instance, you may want a baseline kubelet configuration for all nodes, but you may want to customize the address and authorization fields. This can be done as follows:Main kubelet configuration file contents:apiVersion: kubelet.config.k8s.io/v1beta1 kind: KubeletConfiguration port: 20250 authorization: mode: Webhook webhook: cacheAuthorizedTTL: "5m" cacheUnauthorizedTTL: "30s" serializeImagePulls: false address: "192.168.0.1" Contents of a file in --config-dir directory:apiVersion: kubelet.config.k8s.io/v1beta1 kind: KubeletConfiguration authorization: mode: AlwaysAllow webhook: cacheAuthorizedTTL: "8m" cacheUnauthorizedTTL: "45s" address: "192.168.0.8" The resulting configuration will be as follows:apiVersion: kubelet.config.k8s.io/v1beta1 kind: KubeletConfiguration port: 20250 serializeImagePulls: false authorization: mode: AlwaysAllow webhook: cacheAuthorizedTTL: "8m" cacheUnauthorizedTTL: "45s" address: "192.168.0.8" ListsYou can override the slices/lists values of the kubelet configuration. However, the entire list gets overridden during the merging process. For example, you can override the clusterDNS list as follows:Main kubelet configuration file contents:apiVersion: kubelet.config.k8s.io/v1beta1 kind: KubeletConfiguration port: 20250 serializeImagePulls: false clusterDNS: - "192.168.0.9" - "192.168.0.8" Contents of a file in --config-dir directory:apiVersion: kubelet.config.k8s.io/v1beta1 kind: KubeletConfiguration clusterDNS: - "192.168.0.2" - "192.168.0.3" - "192.168.0.5" The resulting configuration will be as follows:apiVersion: kubelet.config.k8s.io/v1beta1 kind: KubeletConfiguration port: 20250 serializeImagePulls: false clusterDNS: - "192.168.0.2" - "192.168.0.3" - "192.168.0.5" Maps, including Nested StructuresIndividual fields in maps, regardless of their value types (boolean, string, etc.), can be selectively overridden. However, for map[string][]string, the entire list associated with a specific field gets overridden. Let's understand this better with an example, particularly on fields like featureGates and staticPodURLHeader:Main kubelet configuration file contents:apiVersion: kubelet.config.k8s.io/v1beta1 kind: KubeletConfiguration port: 20250 serializeImagePulls: false featureGates: AllAlpha: false MemoryQoS: true staticPodURLHeader: kubelet-api-support: - "Authorization: 234APSDFA" - "X-Custom-Header: 123" custom-static-pod: - "Authorization: 223EW
