How to get ip address from other host in ansible? - vagrant

Question

I have vagrant configured with multiple machines and ansible:
config.vm.box = "ubuntu/trusty64"
config.vm.define "my_server" do |my_server|
my_server.vm.network "private_network", ip: "192.168.50.4"
end
config.vm.define "my_agent" do |my_agent|
my_agent.vm.network "private_network", ip: "192.168.50.5"
end
config.vm.provision "ansible" do |ansible|
ansible.groups = {
"my-server" => ["my_server"],
"my-agent" => ["my_agent"],
"all_groups:children" => ["my-server", "my-agent"]
}
ansible.playbook = "./ansible/my.yml"
end
And vagrant generate inventory file:
# Generated by Vagrant
my_server ansible_ssh_host=127.0.0.1 ansible_ssh_port=2222 ansible_ssh_private_key_file=/.../private_key
my_agent ansible_ssh_host=127.0.0.1 ansible_ssh_port=2200 ansible_ssh_private_key_file=/.../private_key
...
When I run vagrant my_server gets ip:
eth0: 10.0.2.15
eth1: 192.168.50.4
and my_agent gets ip:
eth0: 10.0.2.15
eth1: 192.168.50.5
I want to add in agent configuration ip address of server (from eth1).
I try debug informations about server:
- debug: var=hostvars[item]
with_items: groups['my-server']
but i only gets:
ok: [my_agent] => (item=my_server) => {
"item": "my_server",
"var": {
"hostvars[item]": {
"ansible_ssh_host": "127.0.0.1",
"ansible_ssh_port": 2222,
"ansible_ssh_private_key_file": ".../private_key",
"group_names": [
"all_groups",
"my-server"
],
"inventory_hostname": "my_server",
"inventory_hostname_short": "my_server"
}
}
}
Is it possible to get ip address of server in agent role? If it is possible how I can do it?

Answer 1

I resolve problem. I need add
ansible.limit = "all"
in ansible configuration, because vagrant runs ansible two times: first for my_server and second for my_agent. Second run ansible don't collect informations about my_server. Now ansible runs two times for each server.
Working vagrant configuration:
config.vm.provision "ansible" do |ansible|
ansible.groups = {
"my-server" => ["my_server"],
"my-agent" => ["my_agent"],
"all_groups:children" => ["my-server", "my-agent"]
}
ansible.limit = "all"
ansible.playbook = "./ansible/my.yml"
end
And ansible agent role:
- debug: var=hostvars[item]["ansible_eth1"]["ipv4"]["address"]
with_items: groups['my-server']
sudo: yes
