Infisical Self Host

Infisical Self-Hosted Deployment

This skill guides you through deploying, configuring, and operating Infisical in self-hosted environments. Whether you are running Infisical on Docker, Docker Compose, or Kubernetes, this resource covers essential setup, security hardening, scaling, and maintenance patterns.

Not this skill

The Helm confusion is worth pre-empting: the secrets-operator chart installs the operator; this skill covers the chart that installs the platform. Both come from the same Cloudsmith repo.

Guiding Principles

1. ENCRYPTION_KEY is Critical: This key encrypts all secrets at rest and cannot be recovered if lost. Back it up and rotate it carefully following Infisical's rotation procedures.

   • Standard deployments: a random 16-byte hex string — openssl rand -hex 16
   • FIPS-enabled deployments: a 256-bit base64 key instead — openssl rand -base64 32

2. AUTH_SECRET is Required: This key is used for session and JWT signing. It is 32 bytes (base64), generated with openssl rand -base64 32, and must be stable across restarts.

3. Database Requirements: PostgreSQL is the only supported database. Use 14+ for compatibility; Infisical is extensively tested on 16. Always backup your database before upgrading Infisical. Schema migrations run automatically on boot (since v0.111.0-postgres).

4. Redis is a hard dependency, not just a cache: Beyond caching it holds the background job queue, distributed locks, cross-instance coordination state, and rate-limit counters. The instance will not start unless one of REDIS_URL, REDIS_SENTINEL_HOSTS, or REDIS_CLUSTER_HOSTS is set, and a running instance is degraded while Redis is unreachable.

   • Use Redis 6.x or 7.x; at least 6.2 is advised
   • All three topologies are supported: standalone, Sentinel, and Cluster
   • Active-passive is recommended. Active-active has not been tested and may behave in undocumented ways
   • Set the eviction policy to noeviction. This is required, not a tuning suggestion — evicting keys under memory pressure would silently drop queued work
   • Enable persistence (AOF, or at minimum RDB snapshots) and back Redis up. Pending secret rotations, syncs, and webhook deliveries live there; a Redis that comes back empty loses them
   • Give Redis the same availability target as the app instances — an unreplicated Redis is a single point of failure for the whole deployment

5. Stateless Architecture: Infisical is stateless. Scale horizontally by adding more replicas. All state lives in PostgreSQL and Redis. Each instance needs no more than 2–4 CPU cores and 4–8 GB memory; add containers rather than growing one.

6. FIPS Compliance: Infisical is compliant with FIPS 140-3. Deploy the separate infisical/infisical-fips Docker image (an Enterprise-only image, not a tag on the standard repo) and set FIPS_ENABLED=true. Remember the ENCRYPTION_KEY format changes to 256-bit base64 in FIPS mode.

Quick Start

• Docker Standalone: Pull infisical/infisical:<version>, set environment variables, run on port 8080.
• Docker Compose: Use docker-compose.prod.yml from the repository with PostgreSQL and Redis services.
• Kubernetes: Deploy via Helm chart infisical-standalone-postgres from Cloudsmith registry with optional managed databases.
