Getting started

[dependencies]
helm-wrapper-rs = { version = "0.4.0", features = ["blocking"] }

use crate::blocking::DefaultHelmExecutor;

let helm_executor = DefaultHelmExecutor::new();

helm_executor.uninstall("namespace", "release")?;

helm_executor.install_or_upgrade(
    namespace,
    release_name,
    chart_name,
    chart_version,
    values_overrides,
    values_file,
    helm_options,
)?;

let releases = helm_executor.list_releases()?;

helm_executor.uninstall("namespace", "release")?;

println!("{:?}", releases);

Features

blocking (default)
nonblocking

Mock

Add blocking-mock or nonblocking-mock features:

helm-wrapper-rs = { version = "0.4.0", features=["blocking-mock"] }

Then use MockHelmExecutor.

Run integration tests

What tests do:

Install whoami helm chart
Get information about installed charts (helm releases)
Uninstall whoami helm chart

Kubernetes cluster is required. You can use K3s:

curl -sfL https://get.k3s.io | sh -
chown $USER: /etc/rancher/k3s/k3s.yaml
chmod g-r /etc/rancher/k3s/k3s.yaml

export KUBECONFIG=/etc/rancher/k3s/k3s.yaml

Run tests:

cargo test --no-default-features --features "blocking"
cargo test --no-default-features --features "nonblocking"
