Alloy
Alloy is Grafana's log and telemetry shipper. It replaces Promtail (EOL 2026-03-02). It forwards container and journal logs to Loki.
Host: Dankclaw (one instance per host) — Port: 12345 (loopback) — Docs: https://grafana.com/docs/alloy/latest
Facts
| Item | Value |
|---|---|
| Image | franksdank/alloy:latest (local build: upstream + a static busybox for the healthcheck) |
| Published | 127.0.0.1:12345 → 12345 (its own UI/health port) |
| Unit | dankclaw/observability/quadlet/alloy.container → alloy.service |
| Config | shared/alloy/config.alloy, installed to /opt/alloy/config/ |
| Inputs | host journald socket, podman container logs, /var/log |
| Output | http://loki:3100/loki/api/v1/push |
| Successor to | Promtail (EOL 2026-03-02) |
Why Alloy and not Promtail
Promtail reached end-of-life on 2026-03-02 and Grafana Labs directs new installs to Alloy. This stack uses Alloy from day one.
Configuration
shared/alloy/config.alloy is the source of truth:
- Reads journald logs from the host's
/run/systemd/journal/socket. - Reads container logs from
/var/lib/containers/storage/...(podman). - Forwards to Loki with
joblabels.
Volumes
| Container path | Host path |
|---|---|
/etc/alloy |
/opt/alloy/config |
/run/systemd/journal/socket |
host journald socket (read-only) |
/var/log |
host logs (read-only) |
/var/lib/containers |
podman storage (read-only) |
The UI port is published on purpose
Alloy's UI listens on the container's own 127.0.0.1:12345 by default, and Alloy 1.x refuses to configure the ui service from a config block ("service ui does not support being configured"). Under compose that meant no reachable health endpoint at all: the homepage status card for alloy read down continuously and a deploy had nothing to wait on. The unit therefore passes --server.http.listen-addr=0.0.0.0:12345 and publishes 127.0.0.1:12345 — same posture as the other three: reachable from the host and from Caddy's network, and from nothing off-host. Alloy has no authentication, which is exactly why it is not published wider.
Gotchas
- The journald socket mount is required for journal scraping.
- Container log paths differ between docker (
/var/lib/docker/containers) and podman (/var/lib/containers/storage/...); point the config at the right one per host. - One Alloy per host; do not run a single instance that tries to reach both hosts' logs.
- The unit
Wants=/After=loki.service: without a reachable Loki the write client fails and the pipeline backs up.
