Connect from host to Vagrant VM by Ansible - ansible

Question

How should i define VM made on Vagrant from my host in ansible?
I have just one Vagrant machine with default config:
`
Vagrant.configure("2") do |config|
config.vm.box = "centos/7"
config.vm.network "private_network", ip: "55.55.55.55"
and in ssh-config i have port 2222.
When i try from host ssh dvory#55.55.55.55:2222 i can not login (user is created on both), i am not even prompted set password. Also i have same situation in ansible
55.55.55.55 ansible_ssh_port=2222 ansible_ssh_user=vagrant ansible_ssh_private_key_file=~/.ssh/id_rsa
Is possible to do that in this way? I dont want to create two Vagrant VMs and have server/client, i have no idea where i should put my ansible code to have it persistant per server.

The 2222 SSH port in Vagrant is the value on the host (your localhost) of the forwarded port 22 of the guest (the VM).
==> ansible: Forwarding ports...
ansible: 22 (guest) => 2222 (host) (adapter 1)
So you should connect by using either:
localhost on port 2222
55.55.55.55 on port 22
I don't know if you did put your ~/.ssh/id_rsa.pub in the authorized keys on the guest, but by default it's not and you should use the private key .vagrant/machines/<MACHINE_NAME>/virtualbox/private_key.
Also, you can connect into the VM using SSH with vagrant ssh <MACHINE_NAME>.
Usually I use an inventory script with my vagrant hosts (to put in the same dir as Vagrantfile):
#!/bin/bash
INVENTORY_DIR=$(cd $(dirname $0) && pwd)
list() {
cat <<EOF
{
"all": {
"hosts": [
"$(vagrant status --machine-readable | cut -d ',' -f 2 | sort -u | sed '/^$/d' | paste -sd ',' - | sed 's/,/","/g')"
]
}
}
EOF
}
host() {
local hostname=$1
local port="$(VAGRANT_CWD=${INVENTORY_DIR} vagrant port --guest 22 ${hostname})"
[[ ! ${port} =~ ^[0-9]+$ ]] && port=0
cat <<EOF
{
"ansible_host": "localhost",
"ansible_port": ${port},
"ansible_user": "vagrant",
"ansible_ssh_private_key_file": "${INVENTORY_DIR}/.vagrant/machines/${hostname}/virtualbox/private_key"
}
EOF
}
case $1 in
--list) list;;
--host) host $2;;
*) exit 1;;
esac
Then you can use ansible with --inventory <INVENTORY_SCRIPT>
