In the immich-app/devtools repository on GitHub, I need to find how they create R2 bucket credentials. There's apparently a special requirement for R2 API tokens.

Fetch these:
1. WebFetch https://raw.githubusercontent.com/immich-app/devtools/main/tf/deployment/modules/shared/cloudflare/api-keys/api-keys.tf
2. WebFetch https://api.github.com/search/code?q=r2+api_token+repo:immich-app/devtools+extension:tf
3. WebFetch https://api.github.com/repos/immich-app/devtools/contents/tf/deployment/modules/shared/cloudflare/account

I need to see the exact cloudflare_api_token resource definition for R2 access and any special provider configuration needed.

# Cloudflare R2 API Token Resources

The content defines three API tokens for R2 access with varying configurations:

## 1. **mich_cloudflare_r2_token**
Features dual policies: account-level R2 permissions and bucket-item operations. Includes an IP restriction via `condition.request_ip.in = local.mich_cidrs`, limiting access to specified CIDR ranges.

## 2. **tiles_r2_kv_token**
Combines R2 storage permissions with KV storage access. Uses two policies—one for account-level resources and another for bucket-item operations across all R2 buckets.

## 3. **static_bucket_api_token**
Provides the most restrictive scope. The resource specification limits access to a "single named bucket: `com.cloudflare.edge.r2.bucket.${var.cloudflare_account_id}_default_static`" rather than all buckets.

## Key Pattern
All R2 tokens use permission groups like `"Workers R2 Storage Read"` and `"Workers R2 Storage Bucket Item Write"`, with resources targeting either `"com.cloudflare.api.account.*"` or `"com.cloudflare.edge.r2.bucket.*"` scopes.

# Cloudflare Provider Configuration

The configuration shows two Cloudflare provider blocks:

**Primary Provider:**
```
"provider "cloudflare" {
  api_token = data.terraform_remote_state.api_keys_state.outputs.terraform_key_cloudflare_account
}"
```
This retrieves the API token from remote state data.

**Aliased Provider:**
```
"provider "cloudflare" {
  alias     = "api_keys"
  api_token = var.cloudflare_api_token
}"
```
This creates an alternative provider instance named "api_keys" that uses a variable-sourced token instead.

Both authenticate to Cloudflare using different token sources—one from stored state and one from an input variable.


content:
# Cloudflare API Token Resources

Here are all six `cloudflare_api_token` resources defined in the configuration:

## 1. terraform_cloudflare_account
Comprehensive token with 20 permission groups covering Pages, DNS, Zone settings, Workers (Scripts, KV, Routes), R2 storage, Notifications, Queues, Account settings, and D1 database access across all account resources.

## 2. terraform_cloudflare_docs
Limited token granting "Pages Write" and "DNS Write" permissions for documentation deployment across all account resources.

## 3. terraform_cloudflare_pages_upload
Minimal token restricted to "Pages Write" permission only, designed for Pages deployment operations.

## 4. mich_cloudflare_r2_token
R2 storage token with read/write permissions at both account and bucket item levels, includes IP-based access restrictions via `local.mich_cidrs` condition.

## 5. tiles_r2_kv_token
Dual-purpose token enabling read/write access to R2 storage and KV storage at account level, plus bucket item operations.

## 6. static_bucket_api_token
Narrowly scoped token permitting read/write operations exclusively on the default static bucket (`${var.cloudflare_account_id}_default_static`).

**Note:** There's a bug in outputs for tokens 2 and 3—they reference `terraform_cloudflare_account.value` instead of their own token values.


content:
# R2 Bucket Resource Definitions

## Direct Resources

Four Cloudflare R2 buckets are defined as standalone resources:

1. **tf_state_database_backups** - "name = 'tf-state-database-backups'" in WEUR region
2. **victoriametrics_backups** - "name = 'victoriametrics-backups'" in WEUR region
3. **data_pipeline_vmetrics_backups** - "name = 'data-pipeline-vmetrics-backups'" in WEUR region
4. **outline_database_backups** - "name = 'outline-database-backups'" in WEUR region
5. **static** - "name = 'static'" with no specified region

All direct resources reference `var.cloudflare_account_id` and `location = "WEUR"`.

## Modular Resources

Three additional buckets use the `cloudflare-r2-bucket` module:

- **outline_volsync_backups** - Stores credentials in 1Password under "OUTLINE_VOLSYNC_BACKUPS_BUCKET"
- **victorialogs_volsync_backups** - References "VICTORIALOGS_VOLSYNC_BACKUPS_BUCKET" in vault
- **discord_bot_db_backups** - Uses "DISCORD_BOT_DB_BACKUP_BUCKET" item name

Module-based buckets include `allowed_cidrs = local.mich_cidrs` for access control and integrate with 1Password for credential management.

## Static Bucket Configuration

The static bucket includes custom domain setup via "terraform_data" provisioners that configure DNS, bucket policy, and CORS settings for "static.immich.cloud" with aggressive caching rules.

Perfect! Now I have the complete information. Let me summarize the key findings about R2 bucket credentials in the immich-app/devtools repository:

## R2 API Token Configuration in immich-app/devtools

### Special Requirement for R2 API Tokens

The key discovery is that **R2 API tokens require DUAL POLICY definitions** in Cloudflare Terraform:

1. **Account-level policy** for R2 storage operations:
   - Permission groups: `"Workers R2 Storage Read"` and `"Workers R2 Storage Write"`
   - Resources: `"com.cloudflare.api.account.*"`

2. **Bucket-item policy** for bucket operations:
   - Permission groups: `"Workers R2 Storage Bucket Item Read"` and `"Workers R2 Storage Bucket Item Write"`
   - Resources: `"com.cloudflare.edge.r2.bucket.*"`

### Token Examples

**1. mich_cloudflare_r2_token** (most common pattern):
- Combines both account and bucket-item policies
- Includes IP-based access restrictions: `condition { request_ip { in = local.mich_cidrs } }`
- Allows read/write at both scopes

**2. tiles_r2_kv_token** (dual-purpose):
- Same dual R2 policy structure
- Also includes KV storage permissions
- Used for tiles service with cross-service access

**3. static_bucket_api_token** (most restrictive):
- Only bucket-item permissions
- Resources limited to single named bucket: `"com.cloudflare.edge.r2.bucket.${var.cloudflare_account_id}_default_static"`
- Least privilege approach for static bucket access

### Provider Configuration
Two provider instances are defined:
- Primary: uses remote state data for the API token
- Aliased (`api_keys`): uses a variable-sourced token

The critical pattern is that **all R2 tokens must have the bucket-item policy in addition to the account policy** to function properly. This is the special requirement Cloudflare imposes for R2 API token creation.
