Deleting a Specified DaemonSet

Function

This API is used to delete a DaemonSet resource object.

URI

DELETE /apis/apps/v1/namespaces/{namespace}/daemonsets/{name} (for clusters of v1.9 and later)

DELETE /apis/extensions/v1beta1/namespaces/{namespace}/daemonsets/{name} (for clusters of v1.15 and earlier)

Table 1 describes the parameters of this API.

Table 1 Parameter description

Parameter

Mandatory

Description

name

Yes

Name of the DaemonSet.

namespace

Yes

Object name and auth scope, such as for teams and projects.

pretty

No

If 'true', then the output is pretty printed.

gracePeriodSeconds

No

The duration in seconds before the object should be deleted. Value must be a non-negative integer. The value zero indicates delete immediately. If this value is nil, the default grace period for the specified type will be used. Defaults to a per object value if not specified. zero means delete immediately.

orphanDependents

No

Deprecated: please use the PropagationPolicy, this field will be deprecated in 1.7. Should the dependent objects be orphaned. If true/false, the "orphan" finalizer will be added to/removed from the object's finalizers list. Either this field or PropagationPolicy may be set, but not both.

propagationPolicy

No

Whether and how garbage collection will be performed. Either this field or OrphanDependents may be set, but not both. The default policy is decided by the existing finalizer set in the metadata.finalizers and the resource-specific default policy. Acceptable values are: 'Orphan' - orphan the dependents; 'Background' - allow the garbage collector to delete the dependents in the background; 'Foreground' - a cascading policy that deletes all dependents in the foreground.

Request

Request parameters:

For the description about request parameters, see Table 2.

Table 2 Request parameters

preconditions

No

Must be fulfilled before a deletion is carried out. If not possible, a 409 Conflict status will be returned.

propagationPolicy

No

String

Whether and how garbage collection will be performed. Either this field or OrphanDependents may be set, but not both. The default policy is decided by the existing finalizer set in the metadata.finalizers and the resource-specific default policy. Acceptable values are: 'Orphan' - orphan the dependents; 'Background' - allow the garbage collector to delete the dependents in the background; 'Foreground' - a cascading policy that deletes all dependents in the foreground.

    "propagationPolicy": "Orphan"
}
  • Deleting the pod and then the DaemonSet on the frontend: 
    {
    "kind": "DeleteOptions",
    "apiVersion": "v1",
    "propagationPolicy": "Foreground"
}
  • Deleting the DaemonSet and then the pod on the backend:
