ConfigMap

Mon, 01 Jan 0001 00:00:00 +0000

You can use a ConfigMap to define reusable data in the form of key/value pairs that can then be referenced and used by other resources.

Specification

---
apiVersion: "core.jikkou.io/v1beta2"
kind: ConfigMap
metadata:
 name: '<CONFIG-MAP-NAME>' # Name of the ConfigMap (required)
data: # Map of key-value pairs (required)
 <KEY_1>: "<VALUE_1>"

Example

For example, the below ConfigMap show how to define default config properties namedcKafkaTopicConfig that can then reference and used to define multiple KafkaTopic. resources.

ValidatingResourcePolicy

Mon, 01 Jan 0001 00:00:00 +0000

The ValidatingResourcePolicy resource is used to define validation rules applied to resources or resource changes before they are applied by Jikkou.
It allows enforcing organizational policies, validating constraints, or filtering out undesired operations.

Each policy can select one or more resource kinds and define rules expressed in Google CEL (Common Expression Language).
Rules can either fail the execution or filter the invalid resources, depending on the configured failurePolicy.

Specification

apiVersion: core.jikkou.io/v1
kind: ValidatingResourcePolicy
metadata:
 name: <string> # Required. Unique policy name.
spec:
 failurePolicy: <string> # Required. One of: FAIL | FILTER
 selector:
 matchingStrategy: <string> # Optional. One of: ALL | ANY (default: ALL)
 matchResources:
 - apiVersion: <string> # Optional. API version to match (e.g., core.jikkou.io/v1)
 kind: <string>  # Required. Resource kind (e.g., KafkaTopic)
 matchLabels:
 - key: <string>  # Label key to match
 operator: <string> # One of: In | NotIn | Exists | DoesNotExist
 values: [<string>]  # Optional list of values
 matchExpressions:
 - <string> # CEL expression
 rules:
 - name: <string> # Required. Rule identifier.
 expression: <string> # Required. A CEL expression evaluated against the resource.
 message: <string> # Optional. Static message returned when the rule fails.
 messageExpression: <string> # Optional. CEL expression to generate a dynamic error message.

Fields

Field	Type	Required	Description
`spec.failurePolicy`	`string`	Yes	Defines the policy behavior when validation fails. Possible values: • `FAIL` → stop execution with an error. • `FILTER` → skip the invalid resource(s) but continue processing others.
`spec.selector.matchingStrategy`	`string`	No	Strategy for combining multiple selectors. Possible values: • `ALL` → resource must match all conditions. • `ANY` → resource must match at least one condition. Default: `ALL`.
`spec.selector.matchResources`	`list`	No	Selects resources by API version and kind.
`spec.selector.matchLabels`	`list`	No	Selects resources based on labels, using operators (`In`, `NotIn`, `Exists`, `DoesNotExist`).
`spec.selector.matchExpressions`	`list`	No	Selects resources using CEL expressions for advanced filtering.
`spec.rules`	`list`	Yes	A list of validation rules.
`spec.rules[].name`	`string`	Yes	A unique identifier for the rule.
`spec.rules[].expression`	`string`	Yes	A CEL expression evaluated against the resource. The rule fails when the expression evaluates to `true`.
`spec.rules[].message`	`string`	No	Static error message returned when validation fails.
`spec.rules[].messageExpression`	`string`	No	CEL expression returning a dynamic error message string.

Resource Selection

Policies define which resources they apply to using a selector.
A selector can combine multiple strategies to target resources based on:
