Control the Apply Behavior

Timoni allows changing the default apply behaviour of Kubernetes resources with the action.timoni.sh annotations.

Annotations

CUE	Generated YAML
timoniv1.Action.Force	action.timoni.sh/force: enabled
timoniv1.Action.OneOff	action.timoni.sh/one-off: enabled
timoniv1.Action.Keep	action.timoni.sh/prune: disabled

Force Apply

To recreate immutable resources such as Kubernetes Jobs, these resources can be annotated with action.timoni.sh/force: "enabled".

Example:

package templates

import (
    batchv1 "k8s.io/api/batch/v1"
    timoniv1 "timoni.sh/core/v1alpha1"
)

#TestJob: batchv1.#Job & {
    #config:    #Config
    apiVersion: "batch/v1"
    kind:       "Job"
    metadata: timoniv1.#MetaComponent & {
        #Meta:      #config.metadata
        #Component: "test"
    }
    metadata: annotations: timoniv1.Action.Force
    spec: {...}
}

One-Off Apply

To apply resources only if they don't exist on the cluster, these resources can be annotated with action.timoni.sh/one-off: "enabled".

Example:

package templates

import (
    batchv1 "k8s.io/api/batch/v1"
    timoniv1 "timoni.sh/core/v1alpha1"
)

#InstallJob: batchv1.#Job & {
    #config:    #Config
    apiVersion: "batch/v1"
    kind:       "Job"
    metadata: timoniv1.#MetaComponent & {
        #Meta:      #config.metadata
        #Component: "install"
    }
    metadata: annotations: timoniv1.Action.OneOff
    spec: {...}
}

Disable Pruning

To prevent Timoni's garbage collector from deleting certain resources such as Kubernetes Persistent Volumes, these resources can be annotated with action.timoni.sh/prune: "disabled".

Example:

package templates

import (
    corev1 "k8s.io/api/core/v1"
    timoniv1 "timoni.sh/core/v1alpha1"
)

#DatabasePVC: corev1.#PersistentVolumeClaim & {
    #config:    #Config
    apiVersion: "v1"
    kind:       "PersistentVolumeClaim"
    metadata: timoniv1.#MetaComponent & {
        #Meta:      #config.metadata
        #Component: "database"
    }
    metadata: annotations: timoniv1.Action.Keep
    spec: {...}
}
