#[non_exhaustive]pub enum Patch<T: Serialize> {
Apply(T),
Json(Patch),
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)
Requires kubernetes >= 1.16
Json(Patch)
Using this variant will require you to explicitly provide a type for T
at the moment.
§Example
use kube::api::Patch;
let json_patch = json_patch::Patch(vec![]);
let patch = Patch::Json::<()>(json_patch);
Merge(T)
Strategic(T)
