These roles assume a working eth1. Vagrant is notorious brining
up interfaces on RHEL/CentOS instances. The shell provisioner
will execute before the dependant ansible provisioner.
When download_run_once=True it will try to first download images to host
running vagrant, then upload the images from vagrant host to the vagrant
vms. While trying to upload the images it will ask for a the vagrant
linux user password.
For small environments this behaviour is unnecessary hence changing the
default to download_run_once=False inside the Vagrantfile seems like a
good fix.
using a shared folder can cause race conditions for the download
role as it tries to download files on all the nodes to the same
shared path. This adds a flag to run the tasks in the download
role on just one node.
I accidently left in the old download URL for coreos
even after I switched the box name to be ubuntu, it
worked fine for me because I already had that box
locally so it didn't try to download. This should
resolve this by using the official bento/ubuntu-14.04
box which is a nice minimal image.
We also allow the default behaviour of sharing folder to VMs
By doing this we can stage our download files in a shared location
and speed up subsequent runs significantly.
Finally will create more verbose documentation.
This allows you to simply run `vagrant up` to get a 3 node HA cluster.
* Creates a dynamic inventory and uses the inventory/group_vars/all.yml
* commented lines in inventory.example so that ansible doesn't try to use it.
* added requirements.txt to give easy way to install ansible/ipaddr
* added gitignore files to stop attempts to save unwated files
* changed `Check if kube-system exists` to `failed_when: false` instead of
`ignore_errors`
