## What it does

The skill covers secret creation, version access, version state changes, deletion, expiration, labels, and aliases through `gcloud`. It also includes IAM bindings for individual secrets or project-wide access, with conditions for narrowing which resources a service account can read.

The GKE section uses Workload Identity: a Google Cloud service account receives Secret Manager access, then links to a Kubernetes ServiceAccount. The examples include Secrets Store CSI Driver resources and a Deployment. The commands require an authenticated `gcloud`, the `secretmanager.googleapis.com` API, and suitable IAM roles.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add BagelHole/DevOps-Security-Agent-Skills --skill gcp-secret-manager -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/gcp-secret-manager/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/gcp-secret-manager/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add BagelHole/DevOps-Security-Agent-Skills --skill gcp-secret-manager -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/gcp-secret-manager/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add BagelHole/DevOps-Security-Agent-Skills --skill gcp-secret-manager -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/gcp-secret-manager/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install BagelHole/DevOps-Security-Agent-Skills gcp-secret-manager
```

2. **Manually: put the files in place**
- File: `.github/skills/gcp-secret-manager/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add BagelHole/DevOps-Security-Agent-Skills --skill gcp-secret-manager -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/BagelHole/DevOps-Security-Agent-Skills --path security/secrets/gcp-secret-manager
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/gcp-secret-manager/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add BagelHole/DevOps-Security-Agent-Skills --skill gcp-secret-manager -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/BagelHole/DevOps-Security-Agent-Skills/tree/HEAD/security/secrets/gcp-secret-manager/SKILL.md

## When to use it
- create a secret in Google Cloud Secret Manager
- read or rotate a selected secret version
- restrict access with IAM policy bindings
- connect Secret Manager values to a GKE workload
- set expiration rules for temporary secrets

## Example prompts
- Set up `db-password` in Google Cloud Secret Manager and grant a service account read access.
- Show how to rotate the secret and read its `latest` version.
- Prepare Workload Identity for GKE with a `SecretProviderClass` manifest.

# GCP Secret Manager

Store and manage secrets securely in Google Cloud Platform.

## When to Use This Skill

Use this skill when:
- Managing secrets in GCP environments
- Integrating secrets with GKE workloads via Workload Identity
- Storing API keys, database credentials, or TLS certificates
- Implementing secret versioning and rotation
- Meeting compliance requirements for centralized secret management

## Prerequisites

- GCP project with billing enabled
- `gcloud` CLI installed and authenticated
- Secret Manager API enabled (`secretmanager.googleapis.com`)
- IAM permissions: `roles/secretmanager.admin` for management, `roles/secretmanager.secretAccessor` for reading
- For GKE: Workload Identity configured on the cluster

## Enable the API

```bash
# Enable Secret Manager API
gcloud services enable secretmanager.googleapis.com

# Verify it's enabled
gcloud services list --enabled --filter="name:secretmanager"
```

## Secret Creation and Management

```bash
# Create a secret (creates the secret resource, not the value)
gcloud secrets create db-password \
  --replication-policy="automatic" \
  --labels="env=production,team=platform"

# Add the secret value (first version)
echo -n "S3cur3P@ssw0rd!" | gcloud secrets versions add db-password --data-file=-

# Create secret with value in one command
echo -n '{"username":"dbadmin","password":"S3cur3P@ss!","host":"10.0.1.5","port":5432}' | \
  gcloud secrets create db-credentials --data-file=- \
  --replication-policy="automatic" \
  --labels="env=production,team=platform"

# Create with specific region replication
gcloud secrets create regional-secret \
  --replication-policy="user-managed" \
  --locations="us-central1,us-east1"

# Create with customer-managed encryption key (CMEK)
gcloud secrets create sensitive-secret \
  --replication-policy="user-managed" \
  --locations="us-central1" \
  --kms-key-name="projects/my-project/locations/us-central1/keyRings/my-ring/cryptoKeys/my-key"

# Access the latest version
gcloud secrets versions access latest --secret=db-password

# Access a specific version
gcloud secrets versions access 3 --secret=db-password

# Add a new version (rotation)
echo -n "N3wS3cur3P@ss!" | gcloud secrets versions add db-password --data-file=-

# List all secrets
gcloud secrets list --format="table(name, createTime, labels)"

# List versions of a secret
gcloud secrets versions list db-password --format="table(name, state, createTime)"

# Disable a version (makes it inaccessible but recoverable)
gcloud secrets versions disable 1 --secret=db-password

# Enable a disabled version
