Kubernetes client toolchain — kubectl, helm, and k3d — at stable /usr/bin paths The kubernetes candy installs the three core Kubernetes client tools uniformly across every distro: kubectl (the API client — from the distro package on arch/fedora, or the official dl.k8s.io release mirror as a fallback binary), helm (the chart package manager — from the distro package or the upstream get-helm-3 script), and k3d (the k3d-in-docker cluster manager, always a standalone release binary). Each one lands at a predictable /usr/bin path and answers a version query, so any box composing this candy can drive a cluster with no further setup. The scenarios and check block assert exactly that — they FAIL if any of the three binaries is missing or cannot report its version.

Acceptance plan

This candy’s plan: — the runnable spec charly check executes against a live deployment. check: steps are idempotent probes; run: steps change state.

Intent	Step
run	download=https://github.com/k3d-io/k3d/releases/download/${K3D_VERSION}/k3d-linux-${ARCH}
run	download the kubectl binary (the declarative download verb — content-addressed cache, atomic rename; ARCH is the auto-exported TARGETARCH amd64/arm64, which is the k8s release asset naming)
run	download and run the helm installer script (the declarative download verb, extract sh mode — content-addressed cache, atomic rename)
run	symlink helm onto PATH
check	the kubectl API client binary is installed at /usr/bin/kubectl
check	kubectl reports its client version and exits cleanly
check	the helm chart package manager binary is installed at /usr/bin/helm
check	helm reports its short version string and exits cleanly
check	the k3d cluster manager binary is installed at /usr/bin/k3d
check	k3d reports its release version and exits cleanly
agent-check	with a container runtime available, k3d can provision a local multi-node Kubernetes cluster for development and testing
