Usage
# charly.yml
my-cloud-image:
candy:
base: "quay.io/fedora/fedora-bootc:43"
bootc: true
my-cloud-image-candy:
candy:
- cloud-init
Used In Boxes
Used in bootc images for VM/cloud deployments. Depends on sshd.
Host-side pairing with kind: vm entities
This candy installs the guest-side cloud-init package — the daemon that reads a NoCloud seed ISO at first boot. The host-side companion is the RenderCloudInit path in the charly binary itself (/charly-internals:cloud-init-renderer), which produces that seed ISO from the structured VmSpec.CloudInit block on a kind: vm entity.
The two sides cooperate across the host/guest boundary:
/charly-internals:cloud-init-rendereremitsuser-data+meta-data+network-config+ seeds ISO via xorriso.- This guest-side candy installs cloud-init so the guest reads
/dev/sr0(the seed ISO) at boot. - The
composeUsersadopt-merge pattern (renderer-side) deposits the SSH pubkey in~<base_user>/.ssh/authorized_keyswithoutuseradd.
For cloud_image VMs (source.kind: cloud_image), cloud-init typically comes pre-installed in the upstream qcow2 — this candy isn't needed; author the VM entity directly in vm.yml. For bootc VMs that want cloud-init provisioning, add this candy explicitly. See /charly-vm:vms-catalog for the authoring guide and /charly-vm:arch for a worked example.

- VM instance provisioning
- Cloud instance bootstrapping
- Partition growing with growpart
- System services: cloud-init-local, cloud-init, cloud-config, cloud-final

Use when authoring or modifying a charly PLUGIN — a candy with a `plugin:` block that contributes Providers (verbs/kinds/deploy-targets/steps/builders/commands), its own CUE schema, builtin (compiled-in) or external (out-of-tree git repo). Covers the unified Provider model, the per-plugin CUE-schema contract (single source → Go params for dev + schema-over-Describe RPC for runtime), the SDK, and the loader.

tools
VerifiedTrustedCommunity
The CUE data-validation / configuration CLI (cue), pinned to v0.16.1. Use when working with the cue candy, installing the cue binary into a box or onto a target:local dev host, or running the offline schema-vendoring pipeline that feeds charly's egress validation.

overthinkos/egress
tools
VerifiedTrustedCommunity
CUE EGRESS validation — validating (and, where it adds value, generating) the config files charly WRITES to a system BEFORE the bytes hit disk. MUST be invoked before working on charly/egress.go, the vendored schemas under candy/plugin-egress/egress-schemas/vendor/, the ValidateEgress / registerVendoredEgressKind path, the offline `task cue:vendor` pipeline, or adding an egress schema for any written artifact (cloud-init, k8s manifests, traefik routes, runtime config, install ledger, systemd/quadlet units, ssh_config, libvirt XML).

Kubernetes cluster-probe declarative check verb — the `kube:` check verb (nodes, pods, ingress, storage class, addon health, apply/delete, and arbitrary resource GETs) served out-of-process by the candy/plugin-kube plugin (vendored client-go; no external kubectl required).
