Configure 5 Linux servers with one block code in playbbok ansible_local

Hi,
I am using vagrant to create 5 servers and using ansible to configure each of them to install Nginx and add the the sentence "hello from web server{server number}.
I am trying to understand what is best way to configure the playbook to configure the servers in one block. Now I use 5 blocks that have the same code only the server number is changed(web1, web2,web3, etc) and the number I write to the index file.I am using ansible_local.

vagrantfile
`

Vagrant.configure(“2”) do |config|

N = 5
(1…N).each do |machine_id|
config.vm.define “web#{machine_id}” do |machine|
machine.vm.box = “ubuntu/trusty64”
machine.vm.hostname = “web”
machine.vm.network “private_network”, ip: “10.0.0.#{10+machine_id}”
end

config.vm.provision “ansible_local” do |ansible|
ansible.playbook = “playbook.yml”
ansible.become = true
ansible.extra_vars = { machine: “web#{machine_id}” }
ansible.groups = {
“group1” => [“web”],
}
end
end

`

playbook code

`

  • hosts: web1
    become: true
    tasks:
  • name: ensure nginx is at the latest version
    apt: name=nginx state=latest
  • name: start nginx
    service:
    name: nginx
    state: started
  • name: add server name to nginx html
    lineinfile:
    dest: /usr/share/nginx/html/index.html
    insertafter: “^

    Thank you for using nginx.”
    line:

    hello from web server-1"
