This should make things a little more composable,
by making these roles meta roles that perform no
actions by default we allow each role to own its own
resources.
Kubernetes API server has an option:
```
--advertise-address=<nil>: The IP address on which to advertise the apiserver to members of the cluster. This address must be reachable by the rest of the cluster. If blank, the --bind-address will be used. If --bind-address is unspecified, the host's default interface will be used.
```
kargo does not set --bind-address, thus it binds to eth0, in vagrant and similar
environments this causes issues because nodes cannot talk to eachother over eth0.
This sets `--advertise-address` to `ip` if its set, otherwise the default behavior
of is persisted by using `ansible_default_ipv4.address`.
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.
check_certs task "Check_certs | Set 'sync_certs' to true" was failing
due to the dict not existing, this sets defaults that allows the
correct behavior of the conditionals.
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`
On CoreOS where there is no package management, perform zero-trip
loops instead of throwing an exception for iterating over a member
of an undefined variable.
When kubespray is deployed on OpenStack, the kube-controller-manager is now aware of the cluster and can create new cinder volumes automatically if the PersistentVolumeClaims are annotated accordingly.
Note that this is an alpha feature of kubernetes 1.2
Currently kubespray does not install kubernetes in a way that allows cinder volumes to be used. This commit provides the necessary cloud configuration file and configures kubelet and kube-apiserver to use it.
