# Security Note: Hetzner API Token Placement
|
|
|
|
**Date**: 2026-01-17
|
|
**Severity**: INFORMATIONAL
|
|
**Status**: SAFE (but can be improved)
|
|
|
|
## Current Situation
|
|
|
|
The Hetzner Cloud API token is currently stored in:
|
|
- `tofu/terraform.tfvars` (gitignored, NOT committed)
|
|
|
|
## Assessment
|
|
|
|
✅ **Current Setup is SAFE**:
|
|
- `tofu/terraform.tfvars` is properly gitignored (line 15 in `.gitignore`: `tofu/*.tfvars`)
|
|
- Token has NOT been committed to git history
|
|
- File is local-only
|
|
|
|
⚠️ **However, Best Practice Would Be**:
|
|
- Store token in `secrets/shared.sops.yaml` (encrypted with SOPS)
|
|
- Reference it from terraform.tfvars as a variable
|
|
- Keep terraform.tfvars minimal (only client configs)
|
|
|
|
## Recommended Improvement (Optional)
|
|
|
|
### Option 1: Keep Current Approach (Acceptable)
|
|
**Pros**:
|
|
- Simple
|
|
- Works with OpenTofu's native variable system
|
|
- Already gitignored
|
|
- Easy to use
|
|
|
|
**Cons**:
|
|
- Token stored in plaintext on disk
|
|
- Not encrypted at rest
|
|
- Can't be safely backed up to cloud storage
|
|
|
|
### Option 2: Move to SOPS (More Secure)
|
|
**Pros**:
|
|
- Token encrypted at rest
|
|
- Can be safely backed up
|
|
- Consistent with other secrets
|
|
- Better security posture
|
|
|
|
**Cons**:
|
|
- Slightly more complex workflow
|
|
- Need to decrypt before running tofu
|
|
|
|
#### Implementation (if desired):
|
|
|
|
1. Add token to shared.sops.yaml:
|
|
```bash
|
|
SOPS_AGE_KEY_FILE=keys/age-key.txt sops secrets/shared.sops.yaml
|
|
# Add: hcloud_token: <your-token>
|
|
```
|
|
|
|
2. Update terraform.tfvars to be minimal:
|
|
```hcl
|
|
# No sensitive data here
|
|
# Token loaded from environment variable
|
|
|
|
clients = {
|
|
# ... client configs only ...
|
|
}
|
|
```
|
|
|
|
3. Update deployment scripts to load token:
|
|
```bash
|
|
# Before running tofu:
|
|
export TF_VAR_hcloud_token=$(sops -d secrets/shared.sops.yaml | yq .hcloud_token)
|
|
tofu apply
|
|
```
|
|
|
|
## Recommendation
|
|
|
|
**For current usage**: ✅ No action required - current setup is safe
|
|
|
|
**For enhanced security** (optional): Consider moving to Option 2 when time permits
|
|
|
|
## Verification
|
|
|
|
Confirmed `terraform.tfvars` is NOT in git:
|
|
```bash
|
|
$ git ls-files | grep terraform.tfvars
|
|
tofu/terraform.tfvars.example # Only the example is tracked ✓
|
|
```
|
|
|
|
Confirmed `.gitignore` is properly configured:
|
|
```
|
|
tofu/*.tfvars # Ignores all tfvars ✓
|
|
!tofu/terraform.tfvars.example # Except the example ✓
|
|
```
