Membuat Instance OpenStack dengan Fixed IP

Terkadang kita mungkin memiliki kebutuhan untuk membuat sebuah instance dengan fixed IP (statis) tertentu. Untuk melakukan ini kita harus membuat secara manual port neutron. panduan ini bisa dilakukan untuk network External atau Internal

BUI (Browser User Interface)

  1. Masuk Panel Admin > Networks > Ports > Klik Network External > Ports

  2. Klik +Create Port lalu isi kan bagian yang dibutuhkan sebagai berikut:

  3. Membuat Instance seperti biasa, hanya saja pada tab Networks di lewat atau di Unselect gunakan Network Ports yang sudah kita buat tadi

  4. Verifikasi Instance sudah berjalan dengan IP statis yang sudah kita buat tadi

    CLI (Command Line Interface)

Jika kalian lebih terbiasa menggunakan CLI, berikut caranya:

neutron port-create --fixed-ip subnet_id=SUBNET_ID,ip_address=IP_FROM_POOL --name PORT_NAME NETWORK_ID
