+# Infisical (Secrets Management)
+
+Self-hosted Infisical instance running as a Docker stack on [DOCKER](docker.md) (10.100.0.35). Deployed via Ansible (role `infisical` in the [ansiblearr](https://github.com/dohejw01/ansiblearr) playbook); deployed 2026-04-29.
+
+## Access
+
+- **URL**: https://infisical.dohertylan.com (via Traefik + Cloudflare cert)
+- **Auth**: native Infisical accounts (no Authelia middleware — Infisical has its own login)
+- **First-time setup**: first sign-up becomes the admin. After bootstrapping, set `INVITE_ONLY_SIGNUP=true` in `roles/infisical/defaults/main.yml` and re-deploy to lock further signups.
+
+## Stack layout (on docker host)
+
+`/opt/infisical/` (compose project name `infisical`; service labels carry standard `com.docker.compose.*` only — no custom `project=lmxopcua`-style label):
+
+| Container | Image | Internal port | Host port | Volume |
+|---|---|---|---|---|
+| `infisical` | `infisical/infisical:latest-postgres` | 8080 (HTTP) | none — Traefik handles 443→8080 | — |
+| `infisical-db` | `postgres:16-alpine` | 5432 | none | `/opt/infisical/postgres_data` |
+| `infisical-redis` | `redis:7-alpine` | 6379 | none | `/opt/infisical/redis_data` |
+
+Networks: `traefik` (external, shared with the rest of the stack) and `infisical` (internal-only bridge for db + redis).
+
+## Configuration
+
+Source of truth: `roles/infisical/defaults/main.yml` in the ansible repo. Re-deploys overwrite `/opt/infisical/docker-compose.yml`, so don't edit it on the host.
+
+| Variable | Value (default) | Notes |
+|---|---|---|
+| `infisical_image` | `infisical/infisical:latest-postgres` | Standalone all-in-one image (API + frontend) |
+| `infisical_subdomain` | `infisical` | Becomes `infisical.dohertylan.com` |
+| `infisical_db_user` / `_db_name` | `infisical` / `infisical` | Internal-only — not exposed past the compose network |
+| `infisical_db_password` | `Sonamu89_infisical_db` | dev convention; rotate via group_vars/vault if repo ever leaves the LAN |
+| `infisical_encryption_key` | 32 hex chars | **Do not change after data exists** — used to envelope-encrypt secrets at rest. Changing it makes existing secrets unrecoverable; use Infisical's key-rotation flow if you need to rotate |
+| `infisical_auth_secret` | random base64 | JWT signing key |
+| `infisical_telemetry_enabled` | `false` | Anonymous telemetry opted out |
+
+## Deploy / update
+
+Three equivalent paths:
+
+```bash
+# Via Semaphore UI (or API): http://10.100.0.35:3000  →  template "Deploy Full Stack"
+curl -s -c - http://localhost:3000/api/auth/login -X POST -H 'Content-Type: application/json' \
+  -d '{"auth":"dohertj2","password":"Sonamu89"}' | grep semaphore | awk '{print $NF}' \
+  | xargs -I{} curl -s -b "semaphore={}" -X POST http://localhost:3000/api/project/1/tasks \
+       -H 'Content-Type: application/json' -d '{"template_id":8,"project_id":1}'
+
+# Or directly on the docker host (skips going through Semaphore/git):
+ssh dohertj2@10.100.0.35 'cd /opt/infisical && docker compose up -d'
+
+# Or pull image only (without restart):
+ssh dohertj2@10.100.0.35 'cd /opt/infisical && docker compose pull'
+```
+
+To make a change, edit `roles/infisical/defaults/main.yml` (or the template), commit + push to GitHub, then re-run the Semaphore template.
+
+## Operations
+
+```bash
+# Status
+ssh dohertj2@10.100.0.35 'docker ps --filter name=infisical'
+
+# Logs
+ssh dohertj2@10.100.0.35 'cd /opt/infisical && docker compose logs --tail=200 infisical'
+
+# Restart just the app (keep db/redis up)
+ssh dohertj2@10.100.0.35 'cd /opt/infisical && docker compose restart infisical'
+
+# Full stack restart
+ssh dohertj2@10.100.0.35 'cd /opt/infisical && docker compose up -d --force-recreate'
+
+# psql shell into the db
+ssh dohertj2@10.100.0.35 'docker exec -it infisical-db psql -U infisical -d infisical'
+```
+
+## Backups
+
+Only state worth preserving: `/opt/infisical/postgres_data`. Redis is just a cache.
+
+```bash
+# Hot logical dump (run on docker host)
+docker exec infisical-db pg_dump -U infisical -d infisical | gzip > /mnt/share/backups/infisical-$(date +%F).sql.gz
+```
+
+Restore: stop the stack, drop and recreate the DB, `gunzip < dump.sql.gz | docker exec -i infisical-db psql -U infisical -d infisical`, start the stack. Whatever encryption key was in `defaults/main.yml` at backup time must still be in place — the restored ciphertext is only readable with the same `ENCRYPTION_KEY`.

+
+## Risks / gotchas
+
+- **`ENCRYPTION_KEY` is the master**. Treat changes to that var as a destructive operation. The default is checked into git in the private ansiblearr repo — fine while the repo stays internal; rotate immediately if it ever goes public.
+- **First sign-up gets admin** with no out-of-band gating. Sign up immediately after the initial deploy so a passing scanner doesn't beat you to it.
+- **No Authelia middleware**. Infisical's own auth is the only thing in front of the API — exposed via Cloudflare to the internet at `infisical.dohertylan.com`. Enable Infisical SSO + MFA before storing anything sensitive.
+- **Single-instance**. Postgres + Redis run alongside the app on one box. Acceptable for a homelab; not HA. If the docker host goes down, secrets API is unavailable — plan integrations accordingly (don't make Infisical a hard dependency for things that need to recover during a docker host outage).
