gocryptfs -- Encrypted filesystem support
Layer Properties
| Property | Value |
|----------|-------|
| Install files | layer.yml (packages only) |
Packages
RPM: gocryptfs
Cross-distro coverage
rpm: (Fedora), pac: (Arch — community), deb: (Debian/Ubuntu — gocryptfs available in Debian main) — full parity.
Usage
# image.yml
my-image:
layers:
- gocryptfs
Typically used as part of the ov-full composition layer rather than directly.
Runtime Behavior
When ov config mount or ov start mounts encrypted volumes, each gocryptfs daemon runs inside a systemd-run --scope --user --unit=ov-enc-<image>-<volume> scope unit. This decouples the FUSE mount lifecycle from the container service — mounts survive container stop/restart and remain browsable on the host.
The -allow_other flag is always passed to gocryptfs (required for rootless podman with --userns=keep-id). gocryptfs auto-enables default_permissions, so kernel UNIX permission checks still apply.
See /ov:enc for full encrypted volume operations documentation.

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.

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.

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).
