Enum kube_core::params::Patch[−][src]

#[non_exhaustive]
pub enum Patch<T: Serialize> {
    Apply(T),
    Merge(T),
    Strategic(T),
}
Expand description

Describes changes that should be applied to a resource

Takes arbitrary serializable data for all strategies except Json.

We recommend using (server-side) Apply patches on new kubernetes releases.

See kubernetes patch docs for the older patch types.

Note that patches have different effects on different fields depending on their merge strategies. These strategies are configurable when deriving your CustomResource.

Creating a patch via serde_json

use kube::api::Patch;
let patch = serde_json::json!({
    "apiVersion": "v1",
    "kind": "Pod",
    "metadata": {
        "name": "blog"
    },
    "spec": {
        "activeDeadlineSeconds": 5
    }
});
let patch = Patch::Apply(&patch);

Creating a patch from a type

use kube::api::Patch;
use k8s_openapi::api::rbac::v1::Role;
use k8s_openapi::apimachinery::pkg::apis::meta::v1::ObjectMeta;
let r = Role {
    metadata: ObjectMeta { name: Some("user".into()), ..ObjectMeta::default() },
    rules: Some(vec![])
};
let patch = Patch::Apply(&r);

Variants (Non-exhaustive)

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
Apply(T)

Server side apply

Requires kubernetes >= 1.16

Merge(T)

JSON Merge patch

Strategic(T)

Strategic JSON Merge patch
