    Grafana Loki - Hardened Log Aggregation Server

     Info

    Deployed on AWS
    Free Trial
    This product has charges associated with it for hardening, security configuration, and support. Grafana Loki is a single-binary, horizontally-scalable log aggregation system queried with LogQL, run here monolithic on a single node with filesystem storage. Unlike bare Loki AMIs that ship the HTTP API wide open on 0.0.0.0:3100 with no authentication, no TLS, and usage analytics phoning home, this Lynxroute build is ready out of the box: a unique Basic Auth password generated at first launch, an Nginx TLS reverse proxy on 443, the Loki API and gRPC bound to localhost only, usage analytics disabled, UFW firewall pre-configured, and a CIS Level 1 hardened Ubuntu 24.04 LTS base. AGPL-3.0 license - fully auditable, no vendor lock-in.

    Overview

    This is a repackaged software product wherein additional charges apply for hardening, security configuration, and support.

    WHAT IS GRAFANA LOKI

    Grafana Loki is a horizontally-scalable, multi-tenant log aggregation system, shipped as a single statically linked Go binary and run here in monolithic mode on one node. Instead of indexing the full text of every log line, Loki indexes only a small set of labels and stores compressed log chunks, which keeps storage and cost low. It exposes an HTTP API: push logs in (Promtail, Grafana Alloy, the Docker logging driver, Fluentd or Fluent Bit) and query them back with LogQL, Loki's label-and-filter query language. This image stores chunks and the TSDB index on the local filesystem under /var/lib/loki, with retention and compaction enabled. Loki has no web UI of its own; you query it through Grafana (it pairs with the Lynxroute Grafana image as a data source), logcli, or curl. AGPL-3.0 license, no vendor lock-in. Running your own Loki keeps all log data inside your AWS account.

    WHAT THIS AMI ADDS

    Security hardening:

    • A unique Basic Auth password generated at first launch for the Nginx perimeter (Loki has no native auth)
    • Nginx reverse proxy with TLS - the Loki API proxied on port 443
    • Loki HTTP API (3100) and gRPC (9096) bound to localhost only - Nginx is the only exposed door
    • Usage analytics disabled (no phone-home to the upstream telemetry endpoint)
    • Loki runs as a non-root service with a restricted systemd unit
    • UFW firewall - ports 22, 80, 443 only
    • fail2ban, AppArmor
    • CVE scan - every image is scanned for vulnerabilities before release

    OS hardening (CIS Level 1):

    • CIS Ubuntu 24.04 LTS Level 1 benchmark applied via ansible-lockdown
    • auditd, SSH hardening, Kernel hardening, IMDSv2 enforced

    Compliance artifacts:

    • SBOM - CycloneDX 1.6 at /etc/lynxroute/sbom.json
    • CIS Conformance Report at /etc/lynxroute/cis-report.html
    • CIS Tailored Profile at /usr/share/doc/lynxroute/CIS_TAILORED_PROFILE.md

    Highlights

    • Loki security baked in: a unique Basic Auth password generated at first launch, an Nginx TLS reverse proxy on 443, the Loki API and gRPC bound to localhost only, and usage analytics disabled - unlike bare Loki AMIs that ship the HTTP API open on 0.0.0.0 with no authentication, no TLS, and analytics reporting left on.
    • CIS Level 1 hardened Ubuntu 24.04 LTS: auditd, fail2ban, AppArmor, SSH key-only, IMDSv2 enforced. CVE-scanned before every release. SBOM (CycloneDX) and CIS Conformance Report included.
    • Cost-efficient log aggregation: indexes labels not full text, queried with LogQL, pairs with Grafana as a data source. Grafana Loki AGPL-3.0 license - fully auditable, no vendor lock-in.

    Amazon Machine Image (AMI)

    An AMI is a virtual image that provides the information required to launch an instance. Amazon EC2 (Elastic Compute Cloud) instances are virtual servers on which you can run your applications and workloads, offering varying combinations of CPU, memory, storage, and networking resources. You can launch as many instances from as many different AMIs as you need.

    Additional details

    Usage instructions

    1. Launch instance (t3.medium recommended)
    2. Open Security Group - allow TCP 443 and TCP 80 from your IP
    3. SSH: ssh -i key.pem ubuntu@<PUBLIC_IP>
    4. Read credentials: sudo cat /root/loki-credentials.txt
    5. Open https://<PUBLIC_IP> in your browser - accept the self-signed certificate warning, sign in with the Basic Auth user and the generated password; you will see the Loki API info page
    6. Add Loki to Grafana: data source type Loki, URL https://<PUBLIC_IP>/, Basic Auth on (user admin + the generated password), TLS skip-verify until you install a CA certificate
    7. Ship logs to https://<PUBLIC_IP>/loki/api/v1/push (Promtail, Grafana Alloy, the Docker loki driver) and query with LogQL

    Loki has no web UI of its own - it is a LogQL API backend queried through Grafana, logcli, or curl. The Basic Auth password is generated uniquely at first launch. Credentials are saved to /root/loki-credentials.txt at first boot. Logs are stored on the local filesystem under /var/lib/loki with retention and compaction enabled. Replace the self-signed TLS certificate with a CA-signed certificate (sudo certbot --nginx) for production use.
