Create VM for Nexus OSS

Pertama kita buat dulu sebuah VM dengan specifikasi seperti berikut:

name: nke-ops-nexus-oss
description: Nexus OSS for storing container image
resources: 
    CPUs: 2
    CoresPerCPU: 2
    Memory: 8
disks:
    - type: Disk
      operation: Clone from Image
      image: centos7-2207-2.disk # select vm template we created before
      capacity: 500 GiB
      busType: SCSI
networks:
    subnet: Primary
    assignmentType: Assign Static IP
    ipAddress: 10.xx.xx.71
bootConfiguration:
    mode: Legacy BIOS Mode
    bootPriority: Default
categories:
    - AppFamily:DevOps

Jadi seperti berikut:

Kemudian coba nyalakan vm tersebut, dan login menggunakan user: root pass: passwordnyaAdmin seperti berikut:

Kemudian kita update disknya, karena kita buat virtual disk 500 GiB tetapi secara logical masih default image yaitu 50 GiB seperti berikut:

[root@nke-ops-nexus-oss ~]# df -h | grep \root
/dev/mapper/centos-root   46G  1.7G   44G   4% /

Maka kita harus update lvm disknya dengan menggunakan perintah berikut:

[root@nke-ops-nexus-oss ~]# fdisk -l

[root@nke-ops-nexus-oss ~]# fdisk /dev/sda
