Virtual Cluster Instance
A virtual cluster is a fully functional Kubernetes cluster that runs inside the namespace of another Kubernetes cluster (host cluster). Virtual clusters are very useful if you are hitting the limits of namespaces and do not want to make special exceptions to the multi-tenancy configuration of the underlying cluster, e.g. a user needs their own CRD or user needs pods from 2 namespaces to communicate with each other but your standard NetworkPolicy does not allow this, then a virtual cluster may be perfect for this user.
Example Virtual Cluster
An example Virtual Cluster:
apiVersion: management.loft.sh/v1
kind: VirtualClusterInstance
metadata:
creationTimestamp: null
name: my-virtual-cluster
namespace: loft-p-my-project
spec:
clusterRef: {}
displayName: my-display-name
owner:
user: my-user
parameters: 'my-parameter: my-value'
templateRef:
name: my-virtual-cluster-template
status: {}
Virtual Cluster Reference
kind
required string
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
kind
required string apiVersion
required string
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.

apiVersion
required string metadata
required object
metadata
required object name
required string
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
name
required string generateName
required string
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
generateName
required string namespace
required string
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.

namespace
required string selfLink
required string
Deprecated: selfLink is a legacy read-only field that is no longer populated by the system.
selfLink
required string uid
required string
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
uid
required string resourceVersion
required string
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 .

resourceVersion
required string generation
required integer
A sequence number representing a specific generation of the desired state.
Populated by the system. Read-only.
generation
required integer creationTimestamp
required object
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
creationTimestamp
required object deletionTimestamp
required object
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
deletionTimestamp
required object deletionGracePeriodSeconds
required integer
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.
deletionGracePeriodSeconds
required integer labels
required object
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
labels
required object annotations
required object
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
annotations
required object ownerReferences
required object[]
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.
ownerReferences
required object[] apiVersion
required string
API version of the referent.
apiVersion
required string kind
required string

uid
required string controller
required boolean false
If true, this reference points to the managing controller.
controller
required boolean false blockOwnerDeletion
required boolean false
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.
blockOwnerDeletion
required boolean false finalizers
required string[]
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.
finalizers
required string[] managedFields
required object[]
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.
managedFields
required object[] manager
required string
Manager is an identifier of the workflow managing these fields.
manager
required string operation
required string
Operation is the type of operation which lead to this ManagedFieldsEntry being created.
The only valid values for this field are 'Apply' and 'Update'.
operation
required string apiVersion
required string
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.
apiVersion
required string time
required object
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.
time
required object fieldsType
required string
FieldsType is the discriminator for the different fields format and version.
There is currently only one possible value: "FieldsV1"
fieldsType
required string fieldsV1
required object
FieldsV1 holds the first JSON version format as described in the "FieldsV1" type.
fieldsV1
required object subresource
required string
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.

required string ignoreReconciliation
required boolean true
IgnoreReconciliation tells the controller to ignore reconciliation for this instance -- this
is primarily used when migrating virtual cluster instances from project to project; this
prevents a situation where there are two virtual cluster instances representing the same
virtual cluster which could cause issues with concurrent reconciliations of the same object.
Once the virtual cluster instance has been cloned and placed into the new project, this
(the "old") virtual cluster instance can safely be deleted.
ignoreReconciliation
required boolean true Retrieve: Virtual Clusters
You can either use curl or kubectl to retrieve Virtual Clusters.
- kubectl
- curl
Retrieve a list of Virtual Clusters
Run the following command to list all Virtual Clusters in project my-project
:
kubectl get virtualclusterinstances.management.loft.sh -n loft-p-my-project -o yaml
Retrieve a single Virtual Cluster by name
Run the following kubectl command to get Virtual Cluster my-virtual-cluster
in project my-project
:
kubectl get virtualclusterinstances.management.loft.sh my-virtual-cluster -n loft-p-my-project -o yaml
Retrieve a list of Virtual Clusters
Run the following curl command to list all Virtual Clusters in project my-project
:
curl -s "https://$LOFT_DOMAIN/kubernetes/management/apis/management.loft.sh/v1/namespaces/loft-p-my-project/virtualclusterinstances" \
-X GET --insecure \
-H "Authorization: Bearer $ACCESS_KEY"
Get a single Virtual Cluster by name
Run the following curl command to get Virtual Cluster my-virtual-cluster
in project my-project
:
# Exchange my-virtual-cluster in the url below with the name of the Virtual Cluster
curl -s "https://$LOFT_DOMAIN/kubernetes/management/apis/management.loft.sh/v1/namespaces/loft-p-my-project/virtualclusterinstances/my-virtual-cluster" \
-X GET --insecure \
-H "Authorization: Bearer $ACCESS_KEY"
Create: Virtual Cluster
You can either use curl or kubectl to create a new Virtual Cluster.
Make sure to set the project in the metadata.namespace
field you want to create the Virtual Cluster in. If your project has the id my-project
, the corresponding namespace would be loft-p-my-project
.
- kubectl
- curl
Create a file object.yaml
with the following contents:
apiVersion: management.loft.sh/v1
kind: VirtualClusterInstance
metadata:
creationTimestamp: null
name: my-virtual-cluster
namespace: loft-p-my-project
spec:
clusterRef: {}
displayName: my-display-name
owner:
user: my-user
parameters: 'my-parameter: my-value'
templateRef:
name: my-virtual-cluster-template
status: {}
Then create the Virtual Cluster my-virtual-cluster
in project my-project
with:
kubectl create -f object.yaml -n loft-p-my-project
Create a file object.yaml
with the following contents:
apiVersion: management.loft.sh/v1
kind: VirtualClusterInstance
metadata:
creationTimestamp: null
name: my-virtual-cluster
namespace: loft-p-my-project
spec:
clusterRef: {}
displayName: my-display-name
owner:
user: my-user
parameters: 'my-parameter: my-value'
templateRef:
name: my-virtual-cluster-template
status: {}
Run the following curl command to create a new Virtual Cluster my-virtual-cluster
in project my-project
:
curl -s -X POST --insecure \
"https://$LOFT_DOMAIN/kubernetes/management/apis/management.loft.sh/v1/namespaces/loft-p-my-project/virtualclusterinstances" \
--data-binary "$(cat object.yaml)" \
-H "Content-Type: application/yaml" \
-H "Authorization: Bearer $ACCESS_KEY"
Update: Virtual Cluster
You can either use curl or kubectl to update Virtual Clusters.
- kubectl
- curl
Update Virtual Cluster
Run the following command to update Virtual Cluster my-virtual-cluster
in project my-project
:
kubectl edit virtualclusterinstances.management.loft.sh my-virtual-cluster -n loft-p-my-project
Then edit the object and upon save, kubectl will update the resource.
Patch Virtual Cluster
Patching a resource is useful if you want to generically exchange only a small portion of the object instead of retrieving the whole object first and then modifying it. To learn more about patches in Kubernetes, please take a look at the official docs.
Run the following kubectl command to add a new annotation my-annotation: my-value
to the Virtual Cluster my-virtual-cluster
in project my-project
via a patch:
kubectl patch virtualclusterinstances.management.loft.sh my-virtual-cluster -n loft-p-my-project \
--type json \
-p '[{"op": "add", "path": "/metadata/annotations/my-annotation", "value": "my-value"}]'
Update Virtual Cluster
First retrieve the current object into a file object.yaml
. This could look like:
apiVersion: management.loft.sh/v1
kind: VirtualClusterInstance
metadata:
creationTimestamp: "2023-04-03T00:00:00Z"
generation: 12
name: my-virtual-cluster
namespace: loft-p-my-project
resourceVersion: "66325905"
uid: af5f9f0f-8ab9-4b4b-a595-a95a5921f3c2
spec:
clusterRef: {}
displayName: my-display-name
owner:
user: my-user
parameters: 'my-parameter: my-value'
templateRef:
name: my-virtual-cluster-template
status: {}
Run the following curl command to update a single Virtual Cluster my-virtual-cluster
in project my-project
:
# Replace the my-virtual-cluster in the url below with the name of the Virtual Cluster you want to update
curl -s "https://$LOFT_DOMAIN/kubernetes/management/apis/management.loft.sh/v1/namespaces/loft-p-my-project/virtualclusterinstances/my-virtual-cluster" \
-X PUT --insecure \
-H "Content-Type: application/yaml" \
