Membuat local server Ubuntu 24.04 online ke internet via Cloudflare Tunnel

# Langkah 1: Install `cloudflared` di Ubuntu 24.04

Buat direktori keyring dan unduh GPG key resmi Cloudflare

sudo mkdir -p --mode=0755 /usr/share/keyrings
curl -fsSL https://pkg.cloudflare.com/cloudflare-main.gpg | sudo tee /usr/share/keyrings/cloudflare-main.gpg >/dev/null

Tambahkan repositori Cloudflare ke APT sources

echo "deb [signed-by=/usr/share/keyrings/cloudflare-main.gpg] https://pkg.cloudflare.com/cloudflared any main" | sudo tee /etc/apt/sources.list.d/cloudflare-client.list

Update repositori dan install cloudflared

sudo apt update
sudo apt install cloudflared -y

Langkah 2: Autentikasi `cloudflared` ke Akun Cloudflare

cloudflared tunnel login

Langkah 3: Buat Tunnel Baru

cloudflared tunnel create nama-tunnel

Hasilnya seperti ini:

user@server:~$ cloudflared tunnel create nama-tunnel
Tunnel credentials written to /home/invmtr/.cloudflared/some-uuid.json. cloudflared chose this file based on where your origin certificate was found. Keep this file secret. To revoke these credentials, delete the tunnel.
Created tunnel nama-tunnel with id some-uuid

Langkah 4: Hubungkan Subdomain ke Tunnel (Routing DNS)

cloudflared tunnel route dns nama-tunnel nama.domain.kamu

Hasilnya seperti ini:

2026-10-23T04:58:14Z INF Added CNAME nama.domain.kamu which will route to this tunnel tunnelID=6172bce7-594e-4a53-abf5-f88c52ab189a

Langkah 5: Buat File Konfigurasi Tunnel (`config.yml`)

sudo mkdir -p /etc/cloudflare
sudo nano /etc/cloudflare/config.yml

Masukkan konfigurasi di bawah ini (sesuaikan `<UUID_TUNNEL_ANDA>` dengan Tunnel ID dari **Langkah 3**):

tunnel: <UUID_TUNNEL_ANDA>
credentials-file: /home/invmtr/.cloudflared/<UUID_TUNNEL_ANDA>.json
ingress:
  - hostname: nama.domain.kamu
    service: http://10.60.192.205:8000
  - service: http_status:404

Langkah 6: Install & Jalankan Service (`systemd`)

Agar *tunnel* berjalan otomatis di latar belakang dan selalu aktif meskipun server *restart*:

# 1. Daftarkan cloudflared sebagai system service

sudo cloudflared --config /etc/cloudflare/config.yml service install

# 2. Jalankan servicenya

sudo systemctl start cloudflared

# 3. Aktifkan agar otomatis start saat booting

sudo systemctl enable cloudflared

Cek statusnya untuk memastikan berjalan lancar tanpa error:

sudo systemctl status cloudflared
