---

Syncrd is a custom-controller that allows automatic synchronization of any namespaced kubernetes resource, including custom resources. This controller includes a custom resource, "Syncr", that indicates that group/type of the resource to be copied along with the namespace and name. The resource also has a field for matchLabels to restrict which namespaces the resource is copied to.

The following fields of the Syncr spec indicate the source resource to be copied:

• apiGroup (for core resources, use an empty string)
• apiVersion
• kind
• namespace
• name

The following field is used to restrict the namespaces the resource is copied to:

• matchLabels

Here is a sample Syncr definition for syncing a core resource:

apiVersion: syncrd.atteg.com/v1beta1
kind: Syncr
metadata:
  name: samplesyncr
  namespace: default
spec:
  apiGroup: ""
  apiResource: kconfigs
  apiVersion: v1alpha1
  matchLabels:
    mylabel: myvalue
  name: sourceresourcename
  namespace: default

Here is a sample Syncr definition for syncing a custom resource:

apiVersion: syncrd.atteg.com/v1beta1
kind: Syncr
metadata:
  name: samplesyncr
  namespace: default
spec:
  apiGroup: customgroup.atteg.com
  apiResource: customKind
  apiVersion: v1beta1
  matchLabels:
    somelabel: somevalue
  name: resourcename
  namespace: default
