SOPS Configuration

# === SOPS Encryption Setup ===

# ติดตั้ง
# brew install sops age
# age-keygen -o ~/.sops/age-key.txt
# export SOPS_AGE_KEY_FILE=~/.sops/age-key.txt

# .sops.yaml (Configuration)
# creation_rules:
# - path_regex: \.enc\.yaml$
# age: >-
# age1xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
# - path_regex: production/.*\.yaml$
# kms: arn:aws:kms:ap-southeast-1:123456789:key/abc-def
# - path_regex: staging/.*\.yaml$
# gcp_kms: projects/my-project/locations/global/keyRings/sops/cryptoKeys/sops-key

# เข้ารหัส
# sops -e secrets.yaml > secrets.enc.yaml
# sops -e -i secrets.yaml # In-place encryption

# แก้ไข (เปิด Editor อัตโนมัติ)
# sops secrets.enc.yaml

# ถอดรหัส
# sops -d secrets.enc.yaml
# sops -d --output secrets.yaml secrets.enc.yaml

# ใช้กับ Kubernetes
# sops -d secrets.enc.yaml | kubectl apply -f -

เคล็ดลับ

• Age: ใช้ Age แทน PGP สำหรับ SOPS ง่ายกว่า ปลอดภัยกว่า
• KMS: ใช้ Cloud KMS สำหรับ Production Auto-rotation
• GitOps: ใช้ Flux + SOPS สำหรับ Secret Management บน K8s
• Cert: เริ่มจาก CompTIA Sec+ แล้วไป CKS AWS Security
• Lab: สร้าง Home Lab ฝึกทุกวัน TryHackMe HackTheBox
