dbus -- D-Bus session bus service
Candy Properties
| Property | Value |
|----------|-------|
| Dependencies | supervisord |
| Service | dbus (supervisord, priority 2) |
| Install files | task: |
Environment Variables
| Variable | Value |
|----------|-------|
| DBUS_SESSION_BUS_ADDRESS | unix:path=/tmp/dbus-session |
Packages
dbus-daemon(RPM)
Cross-distro coverage
RPM: dbus-daemon (Fedora) · PAC: dbus (Arch) · DEB: dbus (Debian/Ubuntu). Full parity — same DBUS_SESSION_BUS_ADDRESS env, same supervisord fragment, identical behavior downstream.
Usage
# charly.yml -- now included in all images with supervisord
my-image:
candy:
- dbus
The dbus: check verb
The dbus: check verb drives this session bus from a candy/box plan. It is a
declarative verb served out-of-process by candy/plugin-dbus (EXEC-based: the
plugin drives gdbus from glib2 over charly's DeployExecutor reverse channel);
there is no host charly check dbus subcommand. Author dbus: list/call/
introspect/notify steps with context: [deploy] and run them with
charly check live <image> --filter dbus. See /charly-check:dbus for the full
method catalog and YAML shape.
Notification Delivery Chain
charly cmd/charly tmux cmd → sendVenueNotification() → gdbus call ... org.freedesktop.Notifications.Notify → swaync/mako → desktop popup
For notifications to work, the box needs:
dbuscandy — D-Bus session bus (this candy)swaynccandy — notification daemongdbus(fromglib2) in the venue — the host drives it over the reverse channel
charly status Probe
The dbus probe checks:
- Whether
dbus-daemonprocess is running - Which notification daemon is active (swaync, mako, dunst)
Shows as dbus:ok (notify:swaync) in charly status detail view.
Used In Boxes
- Transitive dependency via
swayin all desktop boxes - Now explicitly added to all boxes with supervisord (openclaw, jupyter, ollama, immich, etc.)

When to Use This Skill
Use when the user asks about:
- D-Bus session bus configuration
DBUS_SESSION_BUS_ADDRESSenvironment variable- the

- Inter-process communication in containers

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.

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).
