Deploying Infisical Secrets Management Platform on Ubuntu...

Infisical is an open-source, end-to-end encrypted secrets management platform for storing and syncing application secrets across teams and environments. It uses PostgreSQL for persistence and Redis for caching. This guide deploys Infisical using Docker Compose with Traefik handling automatic HTTPS. By the end, you'll have a production-ready Infisical instance accessible securely at your domain.

Set Up the Directory Structure and Secrets

1. Create the project directory structure:

$ mkdir -p ~/infisical/{db,redis,letsencrypt}
$ cd ~/infisical

2. Generate the encryption key and auth secret:

$ openssl rand -hex 16
$ openssl rand -base64 32

Note both values — the first is the ENCRYPTION_KEY, the second is the AUTH_SECRET.

3. Create the environment file:

$ nano .env

INFISICAL_DOMAIN=infisical.example.com
LETSENCRYPT_EMAIL=admin@example.com
ENCRYPTION_KEY=HEX_KEY_HERE
AUTH_SECRET=BASE64_SECRET_HERE
POSTGRES_USER=infisical
POSTGRES_PASSWORD=STRONG_DB_PASSWORD
POSTGRES_DB=infisicaldb
DB_CONNECTION_URI=postgres://${POSTGRES_USER}:${POSTGRES_PASSWORD}@db:5432/${POSTGRES_DB}
REDIS_URL=redis://redis:6379

Deploy with Docker Compose

1. Add your user to the Docker group:

$ sudo usermod -aG docker $USER
$ newgrp docker

2. Create the Docker Compose manifest:

$ nano docker-compose.yml

services:
  traefik:
    image: traefik:latest
    container_name: traefik
    restart: unless-stopped
    environment:
      DOCKER_API_VERSION: "1.44"
    command:
      - "--providers.docker=true"
      - "--providers.docker.exposedbydefault=false"
      - "--entrypoints.web.address=:80"
      - "--entrypoints.websecure.address=:443"
      - "--entrypoints.web.http.redirections.entrypoint.to=websecure"
      - "--entrypoints.web.http.redirections.entrypoint.scheme=https"
      - "--certificatesresolvers.le.acme.httpchallenge=true"
      - "--certificatesresolvers.le.acme.httpchallenge.entrypoint=web"
      - "--certificatesresolvers.le.acme.email=${LETSENCRYPT_EMAIL}"
      - "--certificatesresolvers.le.acme.storage=/letsencrypt/acme.json"
    ports:
      - "80:80"
      - "443:443"
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock:ro
      - ./letsencrypt:/letsencrypt

  db:
    image: postgres:16-alpine
    container_name: infisical-db
    restart: unless-stopped
    environment:
      - POSTGRES_USER=${POSTGRES_USER}
      - POSTGRES_PASSWORD=${POSTGRES_PASSWORD}
      - POSTGRES_DB=${POSTGRES_DB}
    volumes:
      - ./db:/var/lib/postgresql/data

  redis:
    image: redis:7-alpine
    container_name: infisical-redis
    restart: unless-stopped

  infisical:
    image: infisical/infisical:latest
    container_name: infisical
    restart: unless-stopped
    depends_on:
      - db
      - redis
    environment:
      - ENCRYPTION_KEY=${ENCRYPTION_KEY}
      - AUTH_SECRET=${AUTH_SECRET}
      - DB_CONNECTION_URI=${DB_CONNECTION_URI}
      - REDIS_URL=${REDIS_URL}
      - SITE_URL=https://${INFISICAL_DOMAIN}
    labels:
      - "traefik.enable=true"
      - "traefik.http.routers.infisical.rule=Host(`${INFISICAL_DOMAIN}`)"
      - "traefik.http.routers.infisical.entrypoints=websecure"
      - "traefik.http.routers.infisical.tls=true"
      - "traefik.http.routers.infisical.tls.certresolver=le"
      - "traefik.http.services.infisical.loadbalancer.server.port=8080"

3. Start the services:

$ docker compose up -d

4. Verify the services are running:

$ docker compose ps

Complete the Setup

Open https://infisical.example.com in a browser.
Create the Super Admin account with your email and a strong password.
Sign in to access the dashboard.

Next Steps

Infisical is running and served securely over HTTPS. From here you can:

Create projects and organize secrets by environment
Integrate the Infisical CLI or SDKs into your applications and CI/CD
Configure secret rotation, access policies, and audit logs
