What is Solr

Apache Solr is an open-source enterprise search platform from the Apache Software Foundation, built on the Apache Lucene library and running as a Java (JVM) service. It provides schema-driven full-text search with hit highlighting, faceting, dynamic clustering, geospatial and range queries, rich document (PDF, Office) handling, near-real-time indexing, and result ranking over a REST-like HTTP API plus the classic Solr Admin UI. Solr indexes and configuration sets are persisted on the local filesystem and queried with sub-second latency; it scales from a single node to large clusters. This image runs Solr standalone (single node, user-managed) on OpenJDK 21. Apache-2.0 license - a self-hosted alternative to hosted search services and a Lucene-based peer to Elasticsearch and OpenSearch, with no per-query fees and no vendor lock-in.

What the Lynxroute image adds

Security hardening:

  • Unique admin password generated per instance at first boot
  • Dual-layer Basic Auth: an nginx TLS reverse proxy plus Solr's native BasicAuthPlugin, both gating the Admin UI and REST API with the same credential
  • Solr bound to 127.0.0.1 only - never exposed directly; nginx terminates TLS on 443
  • UFW firewall - ports 22 (SSH) and 443 (HTTPS) 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
