Testing with Vagrant¶
This is really easy. Vagrant includes an Ansible provisioner and will run the playbook when you first run
vagrant up and again when you run
While Vagrant knows about Ansible, and the playbook specification is in your VagrantFile, you still must have Ansible itself available.
If you’ve installed Ansible globally, no other steps are necessary. If you wish to use a virtualenv to contain your Ansible installation, it’s a little more work to get going:
cd ansible.playbook virtualenv ./ bin/pip install ansible vagrant up
If you wish to run
ansible-playbook directly with the command:
bin/ansible-playbook -i vbox_host.cfg playbook.yml
vbox_host.cfg is automatically generated when vagrant provisions the host server.
ssh stores host keys and checks them every time you try to reconnect to the same address. Since your Vagrant installs are always at the same host and port (127.0.0.1:2222), you will receive SSH Error: Host key verification failed while connecting to 127.0.0.1:2222 error messages each time you install and connect with a new virtual box.
To resolve these errors, use the command:
ssh-keygen -f "~/.ssh/known_hosts" -R [127.0.0.1]:2222
to remove the old host key, then try again.
This should not happen if you’re using the generated vbox_host.cfg, as it turns of Ansible’s host key checking.
Vagrant maps host ports into the guest VirtualBox OS. The standard mapping takes host port 2222 to the guest’s SSH port, 22.
The Vagrantfile included with this kit maps several more ports. The general rule is to map each guest port to a host port 1000 higher:
config.vm.network "forwarded_port", guest: 80, host: 1080 config.vm.network "forwarded_port", guest: 1080, host: 2080 config.vm.network "forwarded_port", guest: 6081, host: 7081 config.vm.network "forwarded_port", guest: 8080, host: 9080 config.vm.network "forwarded_port", guest: 4949, host: 5949
Note that when you use host port 1080 to connect to guest port 80, the virtual hosting will not work correctly. You’ll get the homepage, but links – including those to stylesheets and JS resources, will be wrong. So, you can’t really test virtual host rewriting via Vagrant.
