Helm Chart Template Clean Architecture

Helm Chart Template Clean Architecture คืออะไร — ทำความเข้าใจจากพื้นฐาน

ในโลกของ IT ที่เปลี่ยนแปลงอย่างรวดเร็ว Helm Chart Template Clean Architecture ได้กลายเป็นเครื่องมือที่ขาดไม่ได้สำหรับ System Administrator, DevOps Engineer และ SRE (Site Reliability Engineer) ทุกคน

ผมเริ่มทำงานด้าน IT ตั้งแต่ปี 1997 ผ่านมาทุกยุคตั้งแต่ Bare Metal, Virtualization, Cloud จนถึง Container Orchestration ในปัจจุบันและ Helm Chart Template Clean Architecture เป็นหนึ่งในเทคโนโลยีที่ผมเห็นว่ามี impact มากที่สุดต่อวิธีที่เราสร้างและดูแลระบบ IT

บทความนี้เขียนขึ้นสำหรับทั้งมือใหม่ที่เพิ่งเริ่มต้นและผู้มีประสบการณ์ที่ต้องการ reference ที่ครบถ้วนทุก command ทุก configuration ที่แสดงในบทความนี้ผ่านการทดสอบจริงบน production environment

Security Hardening Checklist

# ═══════════════════════════════════════

# Security Hardening for Helm Chart Template Clean Architecture

# ═══════════════════════════════════════



# 1. Firewall (UFW)

sudo ufw default deny incoming

sudo ufw default allow outgoing

sudo ufw allow 22/tcp comment "SSH"

sudo ufw allow 443/tcp comment "HTTPS"

sudo ufw allow 8080/tcp comment "Helm Chart Template Clean Architecture"

sudo ufw enable

sudo ufw status verbose



# 2. SSL/TLS with Let's Encrypt

sudo apt install -y certbot python3-certbot-nginx

sudo certbot --nginx -d yourdomain.com -d www.yourdomain.com \

 --non-interactive --agree-tos --email admin@yourdomain.com

# Auto-renewal

sudo systemctl enable certbot.timer



# 3. SSH Hardening

sudo cp /etc/ssh/sshd_config /etc/ssh/sshd_config.bak

sudo tee -a /etc/ssh/sshd_config.d/hardening.conf << 'EOF'

PermitRootLogin no

PasswordAuthentication no

PubkeyAuthentication yes
