Menambahkan layanan swift object storage pada openstack yang dideploy dengan kolla ansible pada postingan openstack for lab

Persiapan

openstack swift membutuhkan block storage untuk media penyimpanan.Tambahkan 1 hardisk pada tiap node untuk di khususkan sebagai storage swift.

Node NameIp AddressSwift VolumeDisk
openstack-controller10.79.0.1010GB/dev/sdb
openstack-compute0110.79.0.1110GB/dev/sdb
openstack-compute0210.79.0.1210GB/dev/sdb

jalankan pada semua node

# <WARNING ALL DATA ON DISK will be LOST!>
index=0
for disk in sdb; do
    sudo parted /dev/${disk} -s -- mklabel gpt mkpart KOLLA_SWIFT_DATA 1 -1
    sudo mkfs.xfs -f -L d${index} /dev/${disk}1
    (( index++ ))
done

Verifikasi block storage yang sudah di format

1

lsblk -f

Sebelum menjalankan layanan openstack swift, kita perlu membuat Object Ring, Account ring, dan Container Ring yang berfungsi untuk memberi tahu berbagai layanan Swift di mana data berada di kluster.

tambahkan permission exec pada file ~/swift-rings.sh dan jalankan dengan user sudo

chown +x ~/swift-rings.sh
sudo ~/swift-rings.sh

Deploy openstack Swift

Aktivasi kolla python virtual environment

1

source ~/kolla/bin/activate

Lalu edit konfigurasi nano /etc/kolla/globals.yml

5

enable_swift: "yes"
enable_swift_s3api: "yes"
glance_backend_file: "yes"
glance_backend_swift: "no"
swift_devices_name: "KOLLA_SWIFT_DATA"

Selanjutnya deploy layanan swift dengan perintah:

1

kolla-ansible -i ~/multinode deploy

Setelah selesai semua deactivate kolla python virtual environment lalu install swift cli client

1

sudo apt instll -y python3-swiftclient

Verifikasi hasil pemasangan layanan openstack swift
