Loki Single Binary, Retention On, Reporting Off

Grafana Loki from the upstream release (sha256-verified) as a single-binary system service on loopback with filesystem storage, a TSDB index, retention the compactor enforces and usage reporting off, its configuration checked by loki -verify-config before it lands. The live test pushes one log line and queries it back. Original role, live-tested on Rocky Linux 10.

Documentation

loki

Grafana Loki from the upstream release (sha256-verified), as a single-binary system service on loopback with filesystem storage, a TSDB index, retention switched on and usage reporting switched off, its configuration checked by loki -verify-config before it lands. Original role for EL 10, live-tested with podman on Rocky Linux 10.

No package, so the checksum is the whole story. EL 10 carries no loki; Grafana ships a release with a checksum file beside it. The role downloads both and has Ansible's get_url refuse the asset unless its SHA-256 is the one in the vendor's file, then installs the binaries as root's in /usr/local/bin, pinned by loki_version.

A service account, a hardened unit, a loopback listener. loki is a system user with no shell that owns the data directory and nothing else; the unit runs with NoNewPrivileges, PrivateTmp, ProtectHome and ProtectSystem=strict. The listener is 127.0.0.1:3100 by default, for a proxy that authenticates or a client on the same host; the live test reads the listening sockets and expects loopback only.

A log line, stored and found. The live test pushes one line through /loki/api/v1/push and reads it back through query_range, the proof the distributor, ingester, index and querier all ran in the one process. Readiness takes about twenty seconds after start (the ingester waits before joining its ring); the live test waits for /ready to say ready.

Retention on, reporting off. Upstream's sample configuration keeps logs forever and reports usage to Grafana Labs; the role sets a retention period the compactor enforces (loki_retention_period, 31 days by default) and reporting_enabled: false, and the live test reads the latter back from the file. Loki's own gRPC listener is on loopback too.

ansible-alertmanager

Prometheus Alertmanager from the upstream release (sha256-verified) as a hardened system service on loopback, its cluster gossip listener switched off and its configuration checked by amtool before it lands. The live test posts an alert through the API and reads it back active, held by the default receiver, and expects no 9094 listener at all. Original role, live-tested on Rocky Linux 10.

ansible-alloy

Grafana Alloy from the upstream release (sha256-verified) as a hardened system service on loopback with --disable-reporting, a self-scrape pipeline that proves the collector runs, and its configuration checked by alloy validate before it lands. The live test reads Alloy's own metrics and asks the component API for the scrape component's health. Original role, live-tested on Rocky Linux 10.

ansible-blackbox-exporter

Prometheus Blackbox exporter from the upstream release (sha256-verified) as a hardened system service on loopback with HTTP and TCP modules, checked by --config.check before the file lands. The live test has it probe itself over HTTP and TCP (probe_success 1) and a port with nothing behind it (probe_success 0): it measures, not only answers. Original role, live-tested on Rocky Linux 10.

ansible-grafana-server

Grafana on loopback with a secret key of yours: every install that never set one shares the package's, which encrypts the data-source credentials in its database. Secure cookies and HSTS for the TLS proxy in front; public snapshots, plugin update checks, feedback links and Gravatar switched off. Settings verified through the API, not the file. Original role, live-tested on Rocky Linux 10.

ansible-prometheus-server

Prometheus from the upstream release (EL 10 has no package), sha256-verified, on loopback: the binary listens everywhere and authenticates nobody. Retention time and size as explicit flags, lifecycle and admin endpoints off (the live test POSTs to both), prometheus.yml checked by the promtool it installs. Pairs with grafana-server and node-exporter. Original role, live-tested on Rocky Linux 10.
