Struct kubeclient::clients::Kubernetes

pub struct Kubernetes { /* fields omitted */ }

The main type for instantiating clients for managing kubernetes resources

Methods

impl Kubernetes

fn load_conf<P: AsRef<Path>>(path: P) -> Result<Kubernetes>

Initialize a Kubernetes client from a Kubernets config file

Incomplete: load_conf was only implemented to meet the needs of a single config, so it is currently hard-coded to require a CA cert, a client cert, and skip hostname verification. PRs for improving this are much appreciated.

Examples

let kube = Kubernetes::load_conf("admin.conf")?;

fn config_maps(&self) -> KubeClient<ConfigMap>

Get a kubernetes client for managing ConfigMaps

Examples

let kube = Kubernetes::load_conf("admin.conf")?;
if kube.config_maps().exists("my-config-map")? {
    println!("Found 'my-config-map'")
}

fn deployments(&self) -> KubeClient<Deployment>

Get a kubernetes client for managing Deployments

Examples

let kube = Kubernetes::load_conf("admin.conf")?;
if kube.deployments().exists("web-server")? {
    println!("Found 'web-server' deployment")
}

fn network_policies(&self) -> KubeClient<NetworkPolicy>

Get a kubernetes client for managing NetworkPolicies

Examples

let kube = Kubernetes::load_conf("admin.conf")?;
if kube.network_policies().exists("web-server")? {
    println!("Found 'web-server' network policy")
}

fn nodes(&self) -> KubeClient<Node>

Get a kubernetes client for managing Nodes

Examples

let kube = Kubernetes::load_conf("admin.conf")?;
if kube.nodes().exists("node-123")? {
    println!("Found 'node-123'")
}

fn pods(&self) -> KubeClient<Pod>

Get a kubernetes client for managing Pods

Examples

let kube = Kubernetes::load_conf("admin.conf")?;
if kube.pods().exists("web-server-abcdefgh12345678")? {
    println!("Found 'web-server-abcdefgh12345678' pod")
}

fn secrets(&self) -> KubeClient<Secret>

Get a kubernetes client for managing Secrets

Examples

let kube = Kubernetes::load_conf("admin.conf")?;
if kube.secrets().exists("my-secret")? {
    println!("Found 'my-secret'")
}

fn services(&self) -> KubeClient<Service>

Get a kubernetes client for managing Services

Examples

let kube = Kubernetes::load_conf("admin.conf")?;
if kube.services().exists("web-server")? {
    println!("Found 'web-server' service")
}

fn namespace(&self, namespace: &str) -> Kubernetes

Get a kubernetes client that uses a specific namespace

Examples

let kube = Kubernetes::load_conf("admin.conf")?;
let cluster_info = kube.namespace("kube-system")
    .secrets()
    .get("clusterinfo")?;

fn healthy(&self) -> Result<bool>

Check to see if the Kubernetes API is healthy

Examples

let kube = Kubernetes::load_conf("admin.conf")?;
let is_healthy = kube.healthy()?;

fn apply<P: AsRef<Path>>(&self, path: P) -> Result<()>

Applies a JSON or YAML resource file

This is similar to the kubectl apply CLI commands.

This may be a single file or an entire directory. If the resource(s) specified already exists, this method will NOT replace the resource.

Examples

let kube = Kubernetes::load_conf("admin.conf")?;
let is_healthy = kube.apply("web-server/deployment.yaml")?;

fn replace<P: AsRef<Path>>(&self, path: P) -> Result<()>

Replaces a JSON or YAML resource file

This is similar to the kubectl replace CLI commands.

This may be a single file or an entire directory. If the resource(s) specified already exists, this method will replace the resource.

Examples

let kube = Kubernetes::load_conf("admin.conf")?;
let is_healthy = kube.replace("web-server/deployment.yaml")?;

fn create<R: Resource>(&self, resource: &R) -> Result<R>

Creates a resource from a typed resource defintion

This is similar to the kubectl create CLI commands.

Note: most of the resource type defintions are incomplete Pull requests to fill missing fields/types are appreciated (especially if documented).

Examples:

let kube = Kubernetes::load_conf("admin.conf")?;
let mut secret = Secret::new("web-server");
secret.insert("db_password", "abc123");
let response = kube.create(&secret)?;

Trait Implementations

impl Clone for Kubernetes

fn clone(&self) -> Kubernetes

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
