Examples (示例)

Example 1: List Compute Instances (列出计算实例)

User (Chinese):

显示项目中所有正在运行的 GCE 实例

Assistant Response:

我会列出所有正在运行的 GCE 实例。

<executes: gcloud compute instances list --filter="status=RUNNING">

**Running Compute Engine Instances:**

| Name | Zone | Machine Type | Internal IP | External IP | Status |
|------|------|--------------|-------------|-------------|--------|
| api-server-prod-1 | us-east1-b | n2-standard-4 | 10.0.1.10 | 34.xxx.xxx.1 | RUNNING |
| api-server-prod-2 | us-east1-c | n2-standard-4 | 10.0.1.11 | 34.xxx.xxx.2 | RUNNING |
| worker-prod-1 | us-east1-b | n2-standard-8 | 10.0.2.10 | - | RUNNING |
| db-primary | us-east1-b | n2-highmem-8 | 10.0.3.10 | - | RUNNING |

**Summary:**
- Total running instances: 4
- Machine types: n2-standard-4 (2), n2-standard-8 (1), n2-highmem-8 (1)
- 2 instances with external IPs
- All instances in us-east1 region

Example 2: Storage Bucket Overview (存储桶概览)

User (English):

List all Cloud Storage buckets and their sizes

Assistant Response:

I'll list all GCS buckets with size information.

<executes: gcloud storage buckets list>
<executes: gcloud storage du -s gs://<bucket>/* for each bucket>

**Cloud Storage Buckets:**

| Bucket Name | Location | Storage Class | Size | Objects |
|-------------|----------|---------------|------|---------|
| srp-prod-data | us-east1 | STANDARD | 2.3 TB | 450,230 |
| srp-prod-logs | us-east1 | NEARLINE | 890 GB | 1,250,000 |
| srp-prod-backups | us-east1 | COLDLINE | 5.1 TB | 125 |
| srp-dev-data | us-east1 | STANDARD | 120 GB | 15,430 |

**Summary:**
- Total storage: 8.4 TB
- Monthly estimated cost: ~$180 (based on storage class)
- Largest bucket: srp-prod-backups (5.1 TB)
- Most objects: srp-prod-logs (1.25M objects)

**Recommendations:**
- Consider lifecycle policies for old logs
- Review backup retention policy
- Monitor storage costs

Example 3: Network Firewall Audit (网络防火墙审计)

User (Chinese):

检查是否有过于宽松的防火墙规则

Assistant Response:

我会检查防火墙规则，识别潜在的安全风险。

<executes: gcloud compute firewall-rules list>

**Firewall Rules Audit:**

**✅ Secure Rules (10):**
- allow-internal-prod: 10.0.0.0/8 → All (Internal only)
- allow-ssh-bastion: Specific IPs → tcp:22
- allow-https-lb: Load balancer → tcp:443
- ... (7 more)

**⚠️ Potentially Risky Rules (2):**
1. **allow-all-dev** ⚠️
   - Source: 0.0.0.0/0 (All internet)
   - Ports: tcp:8080, tcp:3000
   - Target: dev-instances
   - **Risk**: Development ports exposed to internet
   - **Recommendation**: Restrict to office IPs or VPN

2. **allow-ssh-temp** ⚠️ HIGH PRIORITY
   - Source: 0.0.0.0/0 (All internet)
   - Port: tcp:22
   - Target: All instances
   - **Risk**: SSH open to entire internet
   - **Recommendation**: DELETE immediately and use bastion host

**Summary:**
- Total rules: 12
- Secure: 10
- Needs review: 2

**Action Items:**
1. 🔴 URGENT: Review and restrict allow-ssh-temp rule
2. 🟡 Review allow-all-dev and limit to VPN/office IPs
3. 🟢 Document all firewall rule purposes

Important Notes

Access Control (访问控制)

• Requires GCP authentication (gcloud)
• Operations limited by IAM permissions
• Read access to most resources
• Some management operations available with proper roles

Safety Guidelines (安全指南)

• Caution with management operations: Always verify before executing
• Prefer read-only commands for investigation
• Use appropriate environments (dev/staging/prod)
• Follow change management processes
• Document all changes

Best Practices (最佳实践)

• Use labels for resource organization
• Enable audit logging
• Regular security reviews
• Monitor costs and quotas
• Use least privilege access

Prerequisites

GCP CLI (gcloud)

Ensure gcloud is installed and configured:

# Check gcloud installation
gcloud version

# Authenticate
gcloud auth login

# Set default project
gcloud config set project srpproduct-dc37e

# Verify access
gcloud projects describe srpproduct-dc37e

Environment Variables

export GCP_PROJECT_ID="srpproduct-dc37e"
export GCP_REGION="us-east1"
export GCP_ZONE="us-east1-b"

Required IAM Roles

Minimum roles needed:

• roles/compute.viewer – View compute resources
• roles/storage.objectViewer – View storage objects
• roles/viewer – Basic project viewing

For management operations:

• roles/compute.instanceAdmin – Manage instances
• roles/storage.admin – Manage storage
• roles/iam.securityReviewer – Security audits

Limitations

Current Limitations

• Uses gcloud CLI (not direct API integration)
• No real-time dashboards
• Limited cost analytics
• No automated remediation
• Manual execution of commands

Future Enhancements

• Direct GCP API integration via MCP
• Real-time resource monitoring
• Cost analytics and optimization
• Automated compliance checks
• Integration with Terraform/IaC
• Alert and notification system

Troubleshooting

Issue 1: “gcloud: command not found”

Solutions:

1. Install gcloud SDK: https://cloud.google.com/sdk/docs/install
2. Add to PATH
3. Restart terminal

Issue 2: “Permission denied”

Solutions:

1. Check current account: gcloud auth list
2. Verify IAM permissions
3. Switch account if needed: gcloud config set account <email>
4. Contact GCP admin

Issue 3: “Project not found”

Solutions:

1. List available projects: gcloud projects list
2. Set correct project: gcloud config set project <project-id>
3. Verify project ID spelling

Security & Compliance

Resource Access Audit

• All operations are logged in Cloud Audit Logs
• Review logs regularly
• Follow principle of least privilege
• Use service accounts for automation

Sensitive Data

• Do not expose credentials
• Use Secret Manager for secrets
• Enable data encryption
• Regular access reviews

Compliance

• Follow company security policies
• Document all infrastructure changes
• Regular compliance audits
• Incident response procedures

Operations Reference

Safe Read Operations (安全的只读操作)

✅ List resources ✅ Describe resources ✅ Get logs ✅ Check status ✅ View metrics

Management Operations (需谨慎执行)

⚠️ Start/stop instances ⚠️ Modify configurations ⚠️ Create/delete resources ⚠️ Change IAM policies ⚠️ Network changes

Always verify management operations before executing and follow change management processes.
