Cluster Access

Globally defined cluster access. You can allow users or teams to access certain clusters here and define their cluster roles in those clusters.

Cluster Access example​

An example Cluster Access:

apiVersion: management.loft.sh/v1
kind: ClusterAccess
metadata:
  creationTimestamp: null
  name: my-cluster-access
spec:
  clusters:
  - '*'
  description: Defines cluster access for the global admins
  displayName: Global Admins
  localClusterAccessTemplate:
    metadata:
      creationTimestamp: null
    spec:
      clusterRoles:
      - name: loft-cluster-admin
      priority: 1000000
      users:
      - team: loft-admins
status: {}

Cluster Access reference​

kind required string pro​

Kind is a string value representing the REST resource this object represents. Servers may infer this from the endpoint the client submits requests to. Cannot be updated. In CamelCase. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds

apiVersion required string pro​

APIVersion defines the versioned schema of this representation of an object. Servers should convert recognized schemas to the latest internal value, and may reject unrecognized values. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#resources

metadata required object pro​

name required string pro​

Name must be unique within a namespace. Is required when creating resources, although some resources may allow a client to request the generation of an appropriate name automatically. Name is primarily intended for creation idempotence and configuration definition. Cannot be updated. More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/names#names

generateName required string pro​

GenerateName is an optional prefix, used by the server, to generate a unique name ONLY IF the Name field has not been provided. If this field is used, the name returned to the client will be different than the name passed. This value will also be combined with a unique suffix. The provided value has the same validation rules as the Name field, and may be truncated by the length of the suffix required to make the value unique on the server.

If this field is specified and the generated name exists, the server will return a 409.

Applied only if Name is not specified. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#idempotency

namespace required string pro​

Namespace defines the space within which each name must be unique. An empty namespace is equivalent to the "default" namespace, but "default" is the canonical representation. Not all objects are required to be scoped to a namespace - the value of this field for those objects will be empty.

Must be a DNS_LABEL. Cannot be updated. More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/namespaces

Deprecated: selfLink is a legacy read-only field that is no longer populated by the system.

uid required string pro​

UID is the unique in time and space value for this object. It is typically generated by the server on successful creation of a resource and is not allowed to change on PUT operations.

Populated by the system. Read-only. More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/names#uids

resourceVersion required string pro​

An opaque value that represents the internal version of this object that can be used by clients to determine when objects have changed. May be used for optimistic concurrency, change detection, and the watch operation on a resource or set of resources. Clients must treat these values as opaque and passed unmodified back to the server. They may only be valid for a particular resource or set of resources.

Populated by the system. Read-only. Value must be treated as opaque by clients and . More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#concurrency-control-and-consistency

generation required integer pro​

A sequence number representing a specific generation of the desired state. Populated by the system. Read-only.

creationTimestamp required object pro​

CreationTimestamp is a timestamp representing the server time when this object was created. It is not guaranteed to be set in happens-before order across separate operations. Clients may not set this value. It is represented in RFC3339 form and is in UTC.

Populated by the system. Read-only. Null for lists. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#metadata

deletionTimestamp required object pro​

DeletionTimestamp is RFC 3339 date and time at which this resource will be deleted. This field is set by the server when a graceful deletion is requested by the user, and is not directly settable by a client. The resource is expected to be deleted (no longer visible from resource lists, and not reachable by name) after the time in this field, once the finalizers list is empty. As long as the finalizers list contains items, deletion is blocked. Once the deletionTimestamp is set, this value may not be unset or be set further into the future, although it may be shortened or the resource may be deleted prior to this time. For example, a user may request that a pod is deleted in 30 seconds. The Kubelet will react by sending a graceful termination signal to the containers in the pod. After that 30 seconds, the Kubelet will send a hard termination signal (SIGKILL) to the container and after cleanup, remove the pod from the API. In the presence of network partitions, this object may still exist after this timestamp, until an administrator or automated process can determine the resource is fully terminated. If not set, graceful deletion of the object has not been requested.

Populated by the system when a graceful deletion is requested. Read-only. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#metadata

deletionGracePeriodSeconds required integer pro​

Number of seconds allowed for this object to gracefully terminate before it will be removed from the system. Only set when deletionTimestamp is also set. May only be shortened. Read-only.

labels required object pro​

Map of string keys and values that can be used to organize and categorize (scope and select) objects. May match selectors of replication controllers and services. More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/labels

annotations required object pro​

Annotations is an unstructured key value map stored with a resource that may be set by external tools to store and retrieve arbitrary metadata. They are not queryable and should be preserved when modifying objects. More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/annotations

ownerReferences required object[] pro​

List of objects depended by this object. If ALL objects in the list have been deleted, this object will be garbage collected. If this object is managed by a controller, then an entry in this list will point to this controller, with the controller field set to true. There cannot be more than one managing controller.

apiVersion required string pro​

API version of the referent.

kind required string pro​

Kind of the referent. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds

name required string pro​

Name of the referent. More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/names#names

uid required string pro​

UID of the referent. More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/names#uids

controller required boolean pro​

If true, this reference points to the managing controller.

blockOwnerDeletion required boolean pro​

If true, AND if the owner has the "foregroundDeletion" finalizer, then the owner cannot be deleted from the key-value store until this reference is removed. See https://kubernetes.io/docs/concepts/architecture/garbage-collection/#foreground-deletion for how the garbage collector interacts with this field and enforces the foreground deletion. Defaults to false. To set this field, a user needs "delete" permission of the owner, otherwise 422 (Unprocessable Entity) will be returned.

finalizers required string[] pro​

Must be empty before the object is deleted from the registry. Each entry is an identifier for the responsible component that will remove the entry from the list. If the deletionTimestamp of the object is non-nil, entries in this list can only be removed. Finalizers may be processed and removed in any order. Order is NOT enforced because it introduces significant risk of stuck finalizers. finalizers is a shared field, any actor with permission can reorder it. If the finalizer list is processed in order, then this can lead to a situation in which the component responsible for the first finalizer in the list is waiting for a signal (field value, external system, or other) produced by a component responsible for a finalizer later in the list, resulting in a deadlock. Without enforced ordering finalizers are free to order amongst themselves and are not vulnerable to ordering changes in the list.

managedFields required object[] pro​

ManagedFields maps workflow-id and version to the set of fields that are managed by that workflow. This is mostly for internal housekeeping, and users typically shouldn't need to set or understand this field. A workflow can be the user's name, a controller's name, or the name of a specific apply path like "ci-cd". The set of fields is always in the version that the workflow used when modifying the object.

manager required string pro​

Manager is an identifier of the workflow managing these fields.

operation required string pro​

Operation is the type of operation which lead to this ManagedFieldsEntry being created. The only valid values for this field are 'Apply' and 'Update'.

apiVersion required string pro​

APIVersion defines the version of this resource that this field set applies to. The format is "group/version" just like the top-level APIVersion field. It is necessary to track the version of a field set because it cannot be automatically converted.

time required object pro​

Time is the timestamp of when the ManagedFields entry was added. The timestamp will also be updated if a field is added, the manager changes any of the owned fields value or removes a field. The timestamp does not update when a field is removed from the entry because another manager took it over.

fieldsType required string pro​

FieldsType is the discriminator for the different fields format and version. There is currently only one possible value: "FieldsV1"

fieldsV1 required object pro​

FieldsV1 holds the first JSON version format as described in the "FieldsV1" type.

subresource required string pro​

Subresource is the name of the subresource used to update that object, or empty string if the object was updated through the main resource. The value of this field is used to distinguish between managers, even if they share the same name. For example, a status update will be distinct from a regular update using the same manager name. Note that the APIVersion field is not related to the Subresource field and it always corresponds to the version of the main resource.

Retrieve: Cluster Accesses​

You can either use curl or kubectl to retrieve Cluster Accesses.

Retrieve a list of Cluster Accesses​

Run the following command to list all Cluster Accesses:

kubectl get clusteraccesses.management.loft.sh  -o yaml

Retrieve a single Cluster Access by name​

Run the following kubectl command to get Cluster Access my-cluster-access:

kubectl get clusteraccesses.management.loft.sh my-cluster-access  -o yaml

Create: Cluster Access​

You can either use curl or kubectl to create a new Cluster Access.

Create a file object.yaml with the following contents:

apiVersion: management.loft.sh/v1
kind: ClusterAccess
metadata:
  creationTimestamp: null
  name: my-cluster-access
spec:
  clusters:
  - '*'
  description: Defines cluster access for the global admins
  displayName: Global Admins
  localClusterAccessTemplate:
    metadata:
      creationTimestamp: null
    spec:
      clusterRoles:
      - name: loft-cluster-admin
      priority: 1000000
