Waxseal

WaxSeal Skill

Go CLI making SealedSecrets GitOps-friendly with Google Secret Manager (GSM) as source of truth.

Core Mental Model

WaxSeal manages three linked artifacts for every secret:

1. GSM secret — plaintext value stored in Google Secret Manager (source of truth)
2. Metadata file — .waxseal/metadata/<shortName>.yaml mapping keys to GSM resources
3. SealedSecret manifest — encrypted YAML in apps/ that ArgoCD deploys

These three must be created together. Never hand-write metadata pointing to GSM secrets that don't exist. Use WaxSeal commands to create them atomically.

Command Reference

WaxSeal has two tiers of commands:

• Primary — shown in waxseal --help: edit, rotate, reseal, check, meta, setup
• Advanced — shown via waxseal advanced: addkey, updatekey, retirekey, discover, gsm bootstrap

The edit command is a TUI wizard (interactive only). The advanced commands (addkey, updatekey, retirekey) are fully scriptable with CLI flags.

Global Flags

Creating New Secrets

addkey — create secret atomically (all three artifacts)

# Interactive mode (TUI wizard, no flags needed)
waxseal addkey my-app-secrets

# Non-interactive with --key flags (prompts only for static key values)
waxseal addkey my-app-secrets \
  --namespace=default \
  --key=username \
  --key=password:random \
  --manifest-path=apps/my-app/sealed-secret.yaml

# All-random keys = fully non-interactive (no prompts at all)
waxseal addkey my-app-secrets \
  --namespace=default \
  --key=api_key:random \
  --key=db_password:random \
  --random-length=64 \
  --manifest-path=apps/my-app/sealed-secret.yaml

# Custom secret type (e.g., CNPG basic-auth)
waxseal addkey my-pg-creds \
  --namespace=default \
  --key=username \
  --key=password:random \
  --type=kubernetes.io/basic-auth \
  --manifest-path=apps/my-app/pg-sealed.yaml

Flags:

Templated key example (Garage S3):

waxseal addkey garage-openobserve-creds \
  --namespace=default \
  --key=access-key:template=GK{{secret}} \
  --key=secret-key:random \
  --generator=randomHex \
  --random-length=12 \
  --manifest-path=apps/infrastructure/garage/garage-openobserve-credentials-sealed.yaml

What addkey does atomically:

1. Creates GSM secrets (via store.CreateSecretVersion)
2. Writes metadata to .waxseal/metadata/
3. Seals and writes the SealedSecret manifest

edit — interactive TUI wizard

waxseal edit           # Pick a secret or create new
waxseal edit addkey    # Jump directly to add-key flow
waxseal edit updatekey # Jump directly to update-key flow
waxseal edit retirekey # Jump directly to retire-key flow

Updating Existing Keys

updatekey — update a key's value in-place

waxseal updatekey my-app-secrets api_key
waxseal updatekey my-app-secrets api_key --generate-random
waxseal updatekey my-app-secrets api_key --generate-random --random-length=64
echo "new-value" | waxseal updatekey my-app-secrets api_key --stdin
waxseal updatekey my-app-secrets new_key --create --generate-random

What updatekey does:

1. Creates a new version in GSM with the new value
2. Updates the metadata with the new version number
3. Reseals the SealedSecret manifest

Retiring, Resealing, Rotating, Health Checks

waxseal retirekey my-old-secret --reason "Replaced" --delete-manifest
waxseal reseal              # All active secrets (re-encrypt, same values)
waxseal rotate my-secret password       # Rotate one key
waxseal rotate my-secret --generated    # Batch rotate ALL generated keys
waxseal check             # Full health check
waxseal meta list secrets  # List all registered secrets
waxseal discover           # Scan repo for existing SealedSecrets

Never Do

• Never hand-write metadata files — use waxseal addkey
• Never use gcloud secrets versions add for managed secrets — use waxseal addkey
• Never use GSM aliases (latest) — always pin numeric versions
• Never put plaintext secrets in metadata, YAML, comments, or logs
• Never hand-edit spec.encryptedData — use waxseal reseal
