openshift statefulset api

Force flag must be unset for non-apply patch requests. A StatefulSetSpec is the specification of a StatefulSet. Watch for changes to the described resources and return them as a stream of add, update, and remove notifications. Either this field or OrphanDependents may be set, but not both. limit is a maximum number of responses to return for a list call. Timeout for the list/watch call. Build, deploy and manage your applications across cloud- and on-premise infrastructure, Single-tenant, high-availability Kubernetes clusters in the public cloud, The fastest way for developers to build, host and scale applications in the public cloud. Valid values are: - All: all dry run stages will be processed. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. replicas is the desired number of replicas of the given Template. ImageStream objects abstract images and enrich them to streams that emit signals when they see that a new image is uploaded into them by e.g. This field is not supported when watch is true. Like a Deployment, a StatefulSet manages … Type indicates the type of the StatefulSetUpdateStrategy. Represents the latest available observations of a statefulset's current state. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. BuildConfig. StatefulSet represents a set of pods with consistent identities. Specify resourceVersion. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned. StatefulSets are designed to deploy stateful applications and clustered applications that save data to persistent storage, such as Compute Engine persistent disks. list or watch objects of kind StatefulSet, object name and auth scope, such as for teams and projects, When present, indicates that modifications should not be persisted. template is the object that describes the pod that will be created if insufficient replicas are detected. Planned for removal in 1.18. partially update the specified StatefulSet. Defaults to everything. The following API endpoints are available: GET: list or watch objects of kind StatefulSet, /apis/apps/v1/namespaces/{namespace}/statefulsets, /apis/apps/v1/namespaces/{namespace}/statefulsets/{name}, PATCH: partially update the specified StatefulSet, /apis/apps/v1/namespaces/{namespace}/statefulsets/{name}/scale, GET: read scale of the specified StatefulSet, PATCH: partially update scale of the specified StatefulSet, PUT: replace scale of the specified StatefulSet, /apis/apps/v1/namespaces/{namespace}/statefulsets/{name}/status, GET: read status of the specified StatefulSet, PATCH: partially update status of the specified StatefulSet, PUT: replace status of the specified StatefulSet. Deprecated: please use the PropagationPolicy, this field will be deprecated in 1.7. Cannot be updated. It corresponds to the StatefulSet’s generation, which is updated on mutation by the API Server. Whether and how garbage collection will be performed. RollingUpdateStatefulSetStrategy is used to communicate parameter for RollingUpdateStatefulSetStrategyType. A Kafka broker and The default policy is OrderedReady, where pods are created in increasing order (pod-0, then pod-1, etc) and the controller will wait until each pod is ready before continuing. A claim in this list takes precedence over any volumes in the template, with the same name. It corresponds to the StatefulSet’s generation, which is updated on mutation by the API Server. Podのstatus項目はPodStatusオブジェクトで、それはphaseのフィールドがあります。 Podのフェーズは、そのPodがライフサイクルのどの状態にあるかを、簡単かつ高レベルにまとめたものです。このフェーズはコンテナやPodの状態を包括的にまとめることを目的としたものではなく、また包括的なステートマシンでもありません。 Podの各フェーズの値と意味は厳重に守られています。ここに記載されているもの以外にphaseの値は存在しないと思ってください。これらがphaseの取りうる値です。 updatedReplicas is the number of Pods created by the StatefulSet controller from the StatefulSet version indicated by updateRevision. Either this field or PropagationPolicy may be set, but not both. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications. Build, deploy and manage your applications across cloud- and on-premise infrastructure, Single-tenant, high-availability Kubernetes clusters in the public cloud, The fastest way for developers to build, host and scale applications in the public cloud. Cannot be updated. Represents the latest available observations of a statefulset’s current state. OPENSHIFT CONTAINER PLATFORM アーキテクチャーについて 1.3. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server the server will respond with a 410 ResourceExpired error indicating the client must restart their list without the continue field. This limits the duration of the call, regardless of any activity or inactivity. Default is RollingUpdate. A selector to restrict the list of returned objects by their labels. The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. The revision history consists of all revisions not represented by a currently applied StatefulSetSpec version. ReplicaSetは、ReplicaSetが対象とするPodをどう特定するかを示すためのセレクターや、稼働させたいPodのレプリカ数、Podテンプレート(理想のレプリカ数の条件を満たすために作成される新しいPodのデータを指定するために用意されるもの)といったフィールドとともに定義されます。ReplicaSetは、指定された理想のレプリカ数にするためにPodの作成と削除を行うことにより、その目的を達成します。ReplicaSetが新しいPodを作成するとき、ReplicaSetはそのPodテンプレートを使用します。 ReplicaSe… However, for a stateful app you might want to use a StatefulSet.Unlike a deployment, the StatefulSet provides certain guarantees about the identity of the pods it is managing (that is, … The alternative policy is Parallel which will create pods in parallel to match the desired scale without waiting, and on scale down will delete all pods at once. StatefulSetUpdateStrategy indicates the strategy that the StatefulSet controller will use to perform updates. RollingUpdateStatefulSetStrategy is used to communicate parameter for RollingUpdateStatefulSetStrategyType. The StatefulSet guarantees that a given network identity will always map to the same storage identity. If true/false, the "orphan" finalizer will be added to/removed from the object's finalizers list. This field is required for apply requests (application/apply-patch) but optional for non-apply patch types (JsonPatch, MergePatch, StrategicMergePatch). Additionally, cluster VMs will need “disk.enableUUID” and VM hardware version 15 or higher. Last time the condition transitioned from one status to another. StatefulSet is the workload API object used to manage stateful applications. replicas is the number of Pods created by the StatefulSet controller. StatefulSetCondition describes the state of a statefulset at a certain point. If unspecified, defaults to 1. revisionHistoryLimit is the maximum number of revisions that will be maintained in the StatefulSet’s revision history. Either this field or PropagationPolicy may be set, but not both. If true/false, the "orphan" finalizer will be added to/removed from the object's finalizers list. Clients should not assume bookmarks are returned at any specific interval, nor may they assume the server will send any BOOKMARK event during a session. Either this field or OrphanDependents may be set, but not both. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. format (oc. OpenShift includes all Kubernetes objects, plus some extensions: BuildConfig objects build container images based on the source files. Servers should convert recognized schemas to the latest internal value, and may reject unrecognized values. Most common API iterations have abstractions, but if there is no openshift-client-python API exposing the oc function you want to run, you can always use oc.invoke to directly pass arguments to an oc invocation on your host. The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. If limit is specified and the continue field is empty, clients may assume that no more results are available. Exact export maintains cluster-specific fields like 'Namespace'. The StatefulSet guarantees that a given network identity will always map to the same storage identity. It controls the deployment and scaling of a set of Pods and provides guarantees about the ordering and uniqueness of these Pods. The default policy is decided by the existing finalizer set in the metadata.finalizers and the resource-specific default policy. readyReplicas is the number of Pods created by the StatefulSet controller that have a Ready Condition. currentRevision, if not empty, indicates the version of the StatefulSet used to generate Pods in the sequence [0,currentReplicas). Last time the condition transitioned from one status to another. The default policy is decided by the existing finalizer set in the metadata.finalizers and the resource-specific default policy. Deprecated. Export strips fields that a user can not specify. The default value is 10. selector is a label query over pods that should match the replica count. It must match the pod template’s labels. Identities are defined as: - Network: A single stable DNS and hostname. Recently, I stumbled upon a StackOverflow question around StatefulSets which made me wonder how well understood they are at … Should this value be exported. The value must be less than or 128 characters long, and only contain printable characters, as defined by https://golang.org/pkg/unicode/#IsPrint. Value must be non-negative integer. Represents the latest available observations of a statefulset’s current state. podManagementPolicy controls how pods are created during initial scale up, when replacing pods on nodes, or when scaling down. Status of the condition, one of True, False, Unknown. Identities are defined as: Network: A single stable DNS and hostname. StatefulSetStatus represents the current state of a StatefulSet. The duration in seconds before the object should be deleted. Learn about a graphical notation for Kubernetes API objects: Kubernetes Deployment Language (KDL). Each pod stamped out by the StatefulSet will fulfill this Template, but have a unique identity from the rest of the StatefulSet. Export strips fields that a user can not specify. 시작하기 전에 튜토리얼을 시작하기 전에 다음의 쿠버네티스 컨셉에 대해 익숙해야 한다. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. Servers should convert recognized schemas to the latest internal value, and may reject unrecognized values. list or watch objects of kind StatefulSet, object name and auth scope, such as for teams and projects. replicas is the number of Pods created by the StatefulSet controller. The continue option should be set when retrieving more results from the server. #!/usr/bin/python import openshift as oc print ('OpenShift client version: {}'. It means user will re-acquire conflicting fields owned by other people. partially update the specified StatefulSet, partially update scale of the specified StatefulSet, replace scale of the specified StatefulSet, partially update status of the specified StatefulSet, replace status of the specified StatefulSet, Promoting Applications Across Environments, MutatingWebhookConfiguration [admissionregistration.k8s.io/v1beta1], ValidatingWebhookConfiguration [admissionregistration.k8s.io/v1beta1], LocalSubjectAccessReview [authorization.k8s.io/v1], SelfSubjectAccessReview [authorization.k8s.io/v1], SelfSubjectRulesReview [authorization.k8s.io/v1], SubjectAccessReview [authorization.k8s.io/v1], ClusterRoleBinding [authorization.openshift.io/v1], ClusterRole [authorization.openshift.io/v1], LocalResourceAccessReview [authorization.openshift.io/v1], LocalSubjectAccessReview [authorization.openshift.io/v1], ResourceAccessReview [authorization.openshift.io/v1], RoleBindingRestriction [authorization.openshift.io/v1], RoleBinding [authorization.openshift.io/v1], SelfSubjectRulesReview [authorization.openshift.io/v1], SubjectAccessReview [authorization.openshift.io/v1], SubjectRulesReview [authorization.openshift.io/v1], CertificateSigningRequest [certificates.k8s.io/v1beta1], ImageStreamImport [image.openshift.io/v1], ImageStreamMapping [image.openshift.io/v1], EgressNetworkPolicy [network.openshift.io/v1], OAuthAuthorizeToken [oauth.openshift.io/v1], OAuthClientAuthorization [oauth.openshift.io/v1], AppliedClusterResourceQuota [quota.openshift.io/v1], ClusterResourceQuota [quota.openshift.io/v1], ClusterRoleBinding [rbac.authorization.k8s.io/v1], ClusterRole [rbac.authorization.k8s.io/v1], RoleBinding [rbac.authorization.k8s.io/v1], PriorityClass [scheduling.k8s.io/v1beta1], PodSecurityPolicyReview [security.openshift.io/v1], PodSecurityPolicySelfSubjectReview [security.openshift.io/v1], PodSecurityPolicySubjectReview [security.openshift.io/v1], RangeAllocation [security.openshift.io/v1], SecurityContextConstraints [security.openshift.io/v1], VolumeAttachment [storage.k8s.io/v1beta1], BrokerTemplateInstance [template.openshift.io/v1], TemplateInstance [template.openshift.io/v1], UserIdentityMapping [user.openshift.io/v1], https://git.k8s.io/community/contributors/devel/api-conventions.md#resources, https://git.k8s.io/community/contributors/devel/api-conventions.md#types-kinds, https://kubernetes.io/docs/concepts/overview/working-with-objects/labels/#label-selectors.
