Namespace Sync in AKO
AKO
Namespace sync helps in syncing objects from specific namespaces to the
NSX Advanced Load Balancer Controller
. This topic introduces the parameters to use Namespace Sync.Parameters
To use Namespace Sync, set the value of these parameters to a non-empty string.
Parameter | Description | Default Value |
|---|---|---|
AKOSettings.namespaceSelector.labelKey | The key used as a label-based selection for the namespaces | Empty |
AKOSettings.namespaceSelector.labelValue | Value used as a label-based selection for the namespaces | Empty |
Any changes to values of these parameters require
AKO
reboot to take effect.If either of the values for the parameters listed above are left empty,
AKO
would sync objects from all namespaces with the NSX Advanced Load Balancer Controller
.When
AKO
is booted up with this setting, label the namespace with the same key:value pair mentioned in values of labelKey
and labelValue
.For example, if the values are
labelKey: app
and labelValue: migrate
in the values.yaml
, label the namespace as app: migrate
.apiVersion: v1 kind: Namespace metadata: creationTimestamp: "2020-12-04T13:20:42Z" labels: app: migrate name: red resourceVersion: "14055620" selfLink: /api/v1/namespaces/red uid: a424bf13-2f4a-4005-a84d-f2fb65acfda0 spec: finalizers: - kubernetes status: phase: Active
AKO
syncs all objects from correctly labelled namespaces.If the label of
red
namespace is changed from app: migrate
(valid) to app: migrate1
(invalid), the following objects of red
namespace will be deleted from NSX Advanced Load Balancer Controller
.- Pools associated with, insecure ingresses/routes
- SNI virtual services associated with secure ingresses/routes
- Virtual services associated with L4 objects
AKO
will sync back objects of a namespace with NSX Advanced Load Balancer Controller
if namespace label is changed from an invalid label to a valid label.
