Ansible Provisioner
Provisioner name: ansible
The Vagrant Ansible provisioner allows you to provision the guest using Ansible playbooks by executing ansible-playbook
from the Vagrant host.
Warning: If you are not familiar with Ansible and Vagrant already, we recommend starting with the shell provisioner. However, if you are comfortable with Vagrant already, Vagrant is a great way to learn Ansible.
Setup Requirements
Install Ansible on your Vagrant host.
Your Vagrant host should ideally provide a recent version of OpenSSH that supports ControlPersist.
If installing Ansible directly on the Vagrant host is not an option in your development environment, you might be looking for the Ansible Local provisioner alternative.
Usage
This page only documents the specific parts of the ansible
(remote) provisioner. General Ansible concepts like Playbook or Inventory are shortly explained in the introduction to Ansible and Vagrant.
Simplest Configuration
To run Ansible against your Vagrant guest, the basic Vagrantfile
configuration looks like:
Vagrant.configure("2") do |config| # # Run Ansible from the Vagrant Host # config.vm.provision "ansible" do |ansible| ansible.playbook = "playbook.yml" end end
Options
This section lists the specific options for the Ansible (remote) provisioner. In addition to the options listed below, this provisioner supports the common options for both Ansible provisioners.
ask_become_pass
(boolean) - require Ansible to prompt for a password when switching to another user with the become/sudo mechanism.The default value is
false
.ask_sudo_pass
(boolean) - Backwards compatible alias for the ask_become_pass option.Deprecation: The
ask_sudo_pass
option is deprecated and will be removed in a future release. Please use theask_become_pass
option instead.
ask_vault_pass
(boolean) - require Ansible to prompt for a vault password.The default value is
false
.force_remote_user
(boolean) - require Vagrant to set theansible_ssh_user
setting in the generated inventory, or as an extra variable when a static inventory is used. All the Ansibleremote_user
parameters will then be overridden by the value ofconfig.ssh.username
of the Vagrant SSH Settings.If this option is set to
false
Vagrant will set the Vagrant SSH username as a default Ansible remote user, butremote_user
parameters of your Ansible plays or tasks will still be taken into account and thus override the Vagrant configuration.The default value is
true
.Compatibility Note: This option was introduced in Vagrant 1.8.0. Previous Vagrant versions behave like if this option was set to
false
.
host_key_checking
(boolean) - require Ansible to enable SSH host key checking.The default value is
false
.raw_ssh_args
(array of strings) - require Ansible to apply a list of OpenSSH client options.Example:
['-o ControlMaster=no']
.It is an unsafe wildcard that can be used to pass additional SSH settings to Ansible via
ANSIBLE_SSH_ARGS
environment variable, overriding any other SSH arguments (e.g. defined in anansible.cfg
configuration file).
Tips and Tricks
Ansible Parallel Execution
Vagrant is designed to provision multi-machine environments in sequence, but the following configuration pattern can be used to take advantage of Ansible parallelism:
# Vagrant 1.7+ automatically inserts a different# insecure keypair for each new VM created. The easiest way# to use the same keypair for all the machines is to disable# this feature and rely on the legacy insecure key.# config.ssh.insert_key = false## Note:# As of Vagrant 1.7.3, it is no longer necessary to disable# the keypair creation when using the auto-generated inventory. N = 3(1..N).each do |machine_id| config.vm.define "machine#{machine_id}" do |machine| machine.vm.hostname = "machine#{machine_id}" machine.vm.network "private_network", ip: "192.168.77.#{20+machine_id}" # Only execute once the Ansible provisioner, # when all the machines are up and ready. if machine_id == N machine.vm.provision :ansible do |ansible| # Disable default limit to connect to all the machines ansible.limit = "all" ansible.playbook = "playbook.yml" end end endend
Tip:
If you apply this parallel provisioning pattern with a static Ansible inventory,
you will have to organize the things so that all the relevant private keys are
provided to the ansible-playbook
command.
The same kind of considerations applies if you are using multiple private keys
for a same machine (see config.ssh.private_key_path
SSH setting).
Force Paramiko Connection Mode
The Ansible provisioner is implemented with native OpenSSH support in mind, and there is no official support for paramiko (A native Python SSHv2 protocol library).
If you really need to use this connection mode though, it is possible to enable paramiko as illustrated in the following configuration examples:
With auto-generated inventory:
ansible.raw_arguments = ["--connection=paramiko"]
With a custom inventory, the private key must be specified (e.g. via an ansible.cfg
configuration file, --private-key
argument, or as part of your inventory file):
ansible.inventory_path = "./my-inventory"ansible.raw_arguments = [ "--connection=paramiko", "--private-key=/home/.../.vagrant/machines/.../private_key"]
