We make use of JSON files containing user variables to build specific versions of CentOS. You tell packer to use a specific user variable file via the -var-file= command line option. This will override the default options on the core packer-metadata.json packer template, which builds CentOS 7 by default.

Customize the boxes by modifying the centos-template.json file

{
  "iso_url": "https://mirrors.aliyun.com/centos/7/isos/x86_64/CentOS-7-x86_64-Minimal-1810.iso",
  "iso_checksum": "38d5d51d9d100fd73df031ffd6bd8b1297ce24660dc8c13a3b8b4534a4bd291c",
  "iso_checksum_type": "sha256",
  "iso_version": "7.6-x64",
  "disk_size": "65536",
  "memory": "1024",
  "cpus": "2"
}

Tip: iso_url value can be local disk path or remote url
