Struct Client 

pub struct Client { /* private fields */ }

Ported from Client in client.go.

Unlike Go’s NewClient(kubeconfig string), which reads the CommandRunner from an ambient context.Context on every call, this takes the executor explicitly at construction, matching docker::Client/git::Client/kubectl::Client.

kubeconfig’s materialization into a temp file + KUBECONFIG env var (Go’s kubeconfigEnv, backed by internal/kubeconfig) mirrors kubectl::Client::kubeconfig_env, which itself mirrors k3d::Driver’s TempKubeconfigGuard – all three exist because xianyun up’s k3d driver uses --kubeconfig-update-default=false, so nothing writes the cluster’s kubeconfig to ~/.kube/config; every client that talks to the cluster has to point itself at the real kubeconfig explicitly or it silently falls back to localhost:8080/the ambient default. Closed alongside kubectl’s own fix (see PORT_NOTES.md): an empty kubeconfig (Go’s no-op path) means kubeconfig_env returns None and every call behaves exactly as before.

Implementations

impl Client

pub fn new( kubeconfig: &str, executor: Arc<dyn CommandRunner + Send + Sync>, ) -> Self

Ported from NewClient.

Trait Implementations

impl Backend for Client

fn install( &self, release_name: &str, chart_path: &str, args: &[&str], ) -> Result<(), ExecError>

Installs a Helm chart. args should include all flags and values for the install command.

fn uninstall( &self, release_name: &str, namespace: &str, ) -> Result<(), ExecError>

Uninstalls a Helm release.

fn upgrade( &self, release_name: &str, chart_path: &str, args: &[&str], ) -> Result<(), ExecError>

Upgrades a Helm release. args should include all flags and values for the upgrade command.

fn list(&self, namespace: &str, filter: &str) -> Result<String, ExecError>

Lists Helm releases in a namespace. Returns JSON output from helm list.

fn repo_list(&self) -> Result<String, ExecError>

Lists configured Helm repositories. Returns JSON output from helm repo list.

fn repo_add( &self, name: &str, url: &str, force_update: bool, ) -> Result<(), ExecError>

Adds a Helm repository, or updates it if force_update is true.

fn repo_update(&self, name: &str) -> Result<(), ExecError>

Updates a specific Helm repository to fetch the latest charts.

fn pull(&self, chart_ref: &str, untar_dir: &str) -> Result<(), ExecError>

Downloads the chart and unpacks it into untar_dir, which must be freshly created.

fn dependency_list(&self, chart_dir: &str) -> Result<String, ExecError>

Returns helm’s dependency list table. It exits 0 whatever it finds, so the caller must read the table rather than the error.

fn dependency_build( &self, chart_dir: &str, skip_refresh: bool, ) -> Result<(), ExecError>

Fetches the dependencies Chart.lock pins, leaving the lock untouched.
