У меня есть Vagrantfile, который на 100% работает. Желаемый результат действительно очевиден. Раскрутите 8 виртуальных машин Ubuntu 16.04, затем подготовьте все серверы с помощью Ansible playbook. Однако в самом конце он делает что-то раздражающее, по какой-то причине playbook запускается дважды, и я не могу понять, почему. Вот мой Vagrantfile.
# This guide is optimized for Vagrant 1.7 and above.
# Although versions 1.6.x should behave very similarly, it is recommended
# to upgrade instead of disabling the requirement below.
Vagrant.require_version ">= 1.7.0"
Vagrant.configure(2) do |config|
N = 8
(1..N).each do |hpc_id|
config.vm.define "hpc#{hpc_id}" do |hpc|
hpc.vm.hostname = "hpc#{hpc_id}"
hpc.vm.network "private_network", ip: "192.168.30.#{200+hpc_id}"
hpc.vm.box = "ubuntu/xenial64"
hpc.ssh.insert_key = false
hpc.vm.provider 'virtualbox' do |vb|
vb.name = "hpc#{hpc_id}"
vb.memory = 512
vb.cpus = 1
vb.gui = false
if hpc_id == N
hpc.vm.provision :ansible do |ansible|
# Disable default limit to connect to all the hpcs
ansible.limit = "all"
ansible.playbook = "site.yml"
ansible.become_user = "root"
ansible.groups = {
"Slurm_Primary_Controller" => ["hpc1"],
"Slurm_Backup_Controller" => ["hpc2"],
"Slurm_Primary_Database" => ["hpc3"],
"Slurm_Backup_Database" => ["hpc4"],
"My_SQL_Database" => ["hpc5"],
"Slurm_Worker" => ["hpc6", "hpc7", "hpc8"],
}
end
end
end
end
end
end
Вот результат работы доступной книги воспроизведения, как показано ниже. Я не включил вывод vagrant build для краткости, поскольку все виртуальные машины запускаются без каких-либо проблем. Однако при необходимости могу добавить это.

Если вы хотите запустить все самостоятельно от начала до конца, я опубликовал его на Github. Я еще не закончил сборку Ansible playbook, поэтому проект явно не завершен.
