Crate for interacting with the Kubernetes API

This crate includes the tools for manipulating Kubernetes resources as well as keeping track of those resources as they change over time

Example

The following example will create a Pod and then watch for it to become available using a manual [Api::watch] call.

use futures::{StreamExt, TryStreamExt};
use kube_client::api::{Api, ResourceExt, ListParams, PatchParams, Patch};
use kube_client::Client;
use k8s_openapi::api::core::v1::Pod;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
// Read the environment to find config for kube client.
// Note that this tries an in-cluster configuration first,
// then falls back on a kubeconfig file.
let client = Client::try_default().await?;

// Interact with pods in the configured namespace with the typed interface from k8s-openapi
let pods: Api<Pod> = Api::default_namespaced(client);

// Create a Pod (cheating here with json, but it has to validate against the type):
let patch: Pod = serde_json::from_value(serde_json::json!({
"apiVersion": "v1",
"kind": "Pod",
"metadata": {
"name": "my-pod"
},
"spec": {
"containers": [
{
"name": "my-container",
"image": "myregistry.azurecr.io/hello-world:v1",
},
],
}
}))?;

// Apply the Pod via server-side apply
let params = PatchParams::apply("myapp");
let result = pods.patch("my-pod", &params, &Patch::Apply(&patch)).await?;

// List pods in the configured namespace
for p in pods.list(&ListParams::default()).await? {
println!("found pod {}", p.name());
}

Ok(())
}
