Namespace Selector

Namespaces can be selected using a regex or a label selector. The regex is applied to the namespace name, while the label selector is applied to the namespace labels. The regex and label selector are combined using an AND operation.

Regex

The regex is applied to the namespace name. The regex is applied directly to the namespace name, so it looks for matches in the namespace name itself. For example, the regex test will match any namespace that contains the string test in its name, such as test, test-1, or my-test-namespace.

The regex is a standard Go regex, so you can use any valid Go regex syntax. For example, the regex ^test-.* will match any namespace that starts with test-, such as test-1, test-2, or test-abc.

Tip

As the regex is matching anything in the namespace name, it is recommended to use a regex that is as specific as possible. For example, if you want to match only namespaces that start with test-, you should use the regex ^test-.* instead of just test. This will help avoid matching unintended namespaces.

Label Selector

The label selector is applied to the namespace labels. The label selector is a standard Kubernetes label selector. For example, the label selector environment=production will match any namespace that has the label environment set to production.

Example

Selecting all namespaces that start with shopping- and have the label environment=production:

apiVersion: automation.kubensync.com/v1alpha1
kind: ManagedResource
metadata:
    name: managedresource-sample
spec:
    avoidResourceUpdate: false
    namespaceSelector:
        regex: "^shopping-.*"
        labelSelector:
            matchLabels:
                environment: production
    template:
        # ...
        # Additional YAML configuration goes here
        # ...
