Question: What are the benefits of ReplicaSet?

Answer: ReplicaSetReplicaSet ensures that a specified number of pod replicas are running at any given time.apiVersion: apps/v1import "k8s.io/api/apps/v1"ReplicaSetReplicaSet ensures that a specified number of pod replicas are running at any given time.apiVersion: apps/v1kind: ReplicaSetmetadata (ObjectMeta)If the Labels of a ReplicaSet are empty, they are defaulted to be the same as the Pod(s) that the ReplicaSet manages. Standard object's metadata.

Question: What is Certificates and Certificate Signing Requests?

Answer: Certificates and Certificate Signing RequestsKubernetes certificate and trust bundle APIs enable automation of X.509 credential provisioning by providing a programmatic interface for clients of the Kubernetes API to request and obtain X.509 certificates from a Certificate Authority (CA).There is also experimental (alpha) support for distributing trust bundles.Certificate signing requestsFEATURE STATE: Kubernetes v1.19 [stable]A CertificateSigningRequest (CSR) resource is used to request that a certificate be signed by a denoted signer, after which the request may be approved or denied before finally being signed.Request signing processThe CertificateSigningRequest resource type allows a client to ask for an X.509 certificate be issued, based on a signing request. The CertificateSigningRequest object includes a PEM-encoded PKCS#10 signing request in the spec.request field. The CertificateSigningRequest denotes the signer (the recipient that the request is being made to) using the spec.signerName field. Note that spec.signerName is a required key after API version certificates.k8s.io/v1. In Kubernetes v1.22 and later, clients may optionally set the spec.expirationSeconds field to request a particular lifetime for the issued certificate. The minimum valid value for this field is 600, i.e. ten minutes.Once created, a CertificateSigningRequest must be approved before it can be signed. Depending on the signer selected, a CertificateSigningRequest may be automatically approved by a controller. Otherwise, a CertificateSigningRequest must be manually approved either via the REST API (or client-go) or by running kubectl certificate approve. Likewise, a CertificateSigningRequest may also be denied, which tells the configured signer that it must not sign the request.For certificates that have been approved, the next step is signing. The relevant signing controller first validates that the signing conditions are met and then creates a certificate. The signing controller then updates the CertificateSigningRequest, storing the new certificate into the status.certificate field of the existing CertificateSigningRequest object. The status.certificate field is either empty or contains a X.509 certificate, encoded in PEM format. The CertificateSigningRequest status.certificate field is empty until the signer does this.Once the status.certificate field has been populated, the request has been completed and clients can now fetch the signed certificate PEM data from the CertificateSigningRequest resource. The signers can instead deny certificate signing if the approval conditions are not met.In order to reduce the number of old CertificateSigningRequest resources left in a cluster, a garbage collection controller runs periodically. The garbage collection removes CertificateSigningRequests that have not changed state for some duration:Approved requests: automatically deleted after 1 hourDenied requests: automatically deleted after 1 hourFailed requests: automatically de


Question: How does Certificates and Certificate Signing Requests work?

Answer: Certificates and Certificate Signing RequestsKubernetes certificate and trust bundle APIs enable automation of X.509 credential provisioning by providing a programmatic interface for clients of the Kubernetes API to request and obtain X.509 certificates from a Certificate Authority (CA).There is also experimental (alpha) support for distributing trust bundles.Certificate signing requestsFEATURE STATE: Kubernetes v1.19 [stable]A CertificateSigningRequest (CSR) resource is used to request that a certificate be signed by a denoted signer, after which the request may be approved or denied before finally being signed.Request signing processThe CertificateSigningRequest resource type allows a client to ask for an X.509 certificate be issued, based on a signing request. The CertificateSigningRequest object includes a PEM-encoded PKCS#10 signing request in the spec.request field. The CertificateSigningRequest denotes the signer (the recipient that the request is being made to) using the spec.signerName field. Note that spec.signerName is a required key after API version certificates.k8s.io/v1. In Kubernetes v1.22 and later, clients may optionally set the spec.expirationSeconds field to request a particular lifetime for the issued certificate.

Question: What is Labels and Selectors?

Answer: Labels and SelectorsLabels are key/value pairs that are attached to objects such as Pods. Labels are intended to be used to specify identifying attributes of objects that are meaningful and relevant to users, but do not directly imply semantics to the core system. Labels can be used to organize and to select subsets of objects. Labels can be attached to objects at creation time and subsequently added and modified at any time. Each object can have a set of key/value labels defined. Each Key must be unique for a given object."metadata": { "labels": { "key1" : "value1", "key2" : "value2" } } Labels allow for efficient queries and watches and are ideal for use in UIs and CLIs. Non-identifying information should be recorded using annotations.MotivationLabels enable users to map their own organizational structures onto system objects in a loosely coupled fashion, without requiring clients to store these mappings.Service deployments and batch processing pipelines are often multi-dimensional entities (e.g., multiple partitions or deployments, multiple release tracks, multiple tiers, multiple micro-services per tier). Management often requires cross-cutting operations, which breaks encapsulation of strictly hierarchical representations, especially rigid hierarchies determined by the infrastructure rather than by users.Example labels:"release" : "stable", "release" : "canary""environment" : "dev", "environment" : "qa", "environment" : "production""tier" : "frontend", "tier" : "backend", "tier" : "cache""partition" : "customerA", "partition" : "customerB""track" : "daily", "track" : "weekly"These are examples of commonly used labels; you are free to develop your own conventions. Keep in mind that label Key must be unique for a given object.Syntax and character setLabels are key/value pairs. Valid label keys have two segments: an optional prefix and name, separated by a slash (/). The name segment is required and must be 63 characters or less, beginning and ending with an alphanumeric character ([a-z0-9A-Z]) with dashes (-), underscores (_), dots (.), and alphanumerics between. The prefix is optional. If specified, the prefix must be a DNS subdomain: a series of DNS labels separated by dots (.), not longer than 253 characters in total, followed by a slash (/).If the prefix is omitted, the label Key is presumed to be private to the user. Automated system components (e.g. kube-scheduler, kube-controller-manager, kube-apiserver, kubectl, or other third-party automation) which add labels to end-user objects must specify a prefix.The kubernetes.io/ and k8s.io/ prefixes are reserved for Kubernetes core components.Valid label value:must be 63 characters or less (can be empty),unless empty, must begin and end with an alphanumeric character ([a-z0-9A-Z]),could contain dashes (-), underscores (_), dots (.), and alphanumerics between.For example, here's a manifest for a Pod that has two labels environment: production and app: nginx:apiVersion: v1 kind: Pod metadata: na
