gnupg -- GnuPG encryption and signing tools
Candy Properties
| Property | Value |
|----------|-------|
| Install files | charly.yml (packages only) |
Packages
RPM: gnupg2 · PAC: gnupg · DEB: gnupg — full cross-distro parity. Note: gnupg is also in the debian distro's bootstrap package set (see /charly-distros:debian) because downstream candies need gpg --dearmor at build time.
Usage
# charly.yml
my-image:
candy:
- gnupg
Typically used as part of the agent-forwarding composition candy rather than directly.
Runtime Behavior
Provides gpg, gpgconf, gpg-agent, gpg-connect-agent binaries inside the container. When combined with SSH/GPG agent forwarding (charly shell, charly start direct mode), the container's GPG uses the host's agent for private key operations (signing, decryption) via a forwarded socket.
The container has its own keyring (public keys must be imported separately with gpg --import). No host keyring is mounted — only the agent socket is forwarded.
Used In Boxes
Part of agent-forwarding composition candy, used in 27 application boxes including: charly-arch, charly-fedora, nvidia, jupyter, ollama, openclaw, immich, comfyui, selkies-desktop, and all other non-base boxes.

VerifiedTrustedCommunity
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).
