Keeping the dynamic inventory in the `sample-inventory` alongside the
`group_vars` poses a problem: when we update the inventory, our users
won't get the latest version.
The dynamic inventory should be independent of the OpenShift or
OpenStack configuration and the users should be able to either pass it
explicitly or create a symlink if they want.

Automatic merge from submit-queue.
Spelling and grammar changes to the advanced-configuration.md file.
I noticed some spelling errors when trying to read the OpenStack `advanced_configuration.md` file so I wanted to contribute the fixed spelling.

When deploying on OpenStack with internal DNS configured, this will set
`openshift_hostname` to the Nova server name instead of its IP address.
Without those two matching, the OpenStack cloud provider configuration
will fail and the OpenShift nodes will not start.

As described in[1], OpenShift currently only works with Block Storage
API v2 and the version autodetection is failing to figure that out.

Openstack fixes
This includes a few fixes for the OpenStack provider.
It should fix #6555 and possibly also #6560.

The OpenStack dynamic inventory was setting the
`openshift_node_labels` value as a string which causes a failure with
the `lib_utils_oo_dict_to_keqv_list` filter.
Fixes #6555

Migrate to import_role for static role inclusion

In Ansible 2.2, the include_role directive came into existence as
a Tech Preview. It is still a Tech Preview through Ansible 2.4
(and in current devel branch), but with a noteable change. The
default behavior switched from static: true to static: false
because that functionality moved to the newly introduced
import_role directive (in order to stay consistent with include*
being dynamic in nature and `import* being static in nature).
The dynamic include is considerably more memory intensive as it will
dynamically create a role import for every host in the inventory
list to be used. (Also worth noting, there is at the time of this
writing an object allocation inefficiency in the dynamic include
that can in certain situations amplify this effect considerably)
This change is meant to mitigate the pressure on memory for the
Ansible control host.
We need to evaluate where it makes sense to dynamically include roles
and revert back to dynamic inclusion if and where it makes sense to do
so.

Support private/public hostnames suffixes for DNS records.
Real hostnames, Inventory variables, Nova servers and ansible
hostnames will ignore the custom suffixes. Those are only for
nsupdates sent to external DNS servers.
Related change: add openshift_openstack_public_dns_domain to
the role defaults to not rely on the group vars example only.

* Do not manage hostnames for openstack cloud provider,
let cloud-init to do its job.
* Make python-dns / dnspython dependency check conditional.
* Drop not used dns node flavor and image.
* Do not manage dns nodes and sec groups in heat stacks.
* Keep supporting dynamic updates for private DNS records, yet only
limited to an external DNS managed elsewhere (not deployed by
the openshift_openstack provider). So users may still benefit from
this feature, sending nsupdates to private and public servers as
they want it.
* Fix openstack default for external nsupdate keys. It should be
undefined by default as the dns-populate logic is based on that.
* Fix dns records generation for openstack provider's populate-dns
* Update docs

With pacemaker removed there is no longer a need for
openshift.master.cluster_method. We only have one option.

Unlike other cloud providers, OpenStack VMs are not able to resolve each
other by their names. If you try to run the playbooks against nodes
without a pre-created /etc/hosts or a DNS that provides the hostname/ip
resolution, it will fail.
By setting the `openshift_hostname` variable to each node's IP address,
we're able to deploy a functional cluster without running a custom DNS.
It is still possible to provide an external server with nsupdate keys
and have it be populated, but that is no longer a hard requirement.

This makes sure that all the variables used in the `openshift_openstack`
role are prefixed with `openshift_openstack_` as is the convention.
|
|
|
|
|
| |
Most of the vars in `roles/openshift_openstack/defaults/main.yml` are
now prefixed with `openstack_`.
|
|
|
|
|
| |
These options will have no effect until we add static inventory and
bastion support back in.

They're not necessary for the initial PR so let's add them properly
later.

They're duplicating a lot of functionality that's already in
openshift-ansible and they're not actually used from the provisioning
playbooks.
We'll revisit them later.
|
|
|
|
|
|
|
|
|
| |
All the tasks that were previously in playbooks are now under
`roles/openshift_openstack`.
The `openshift-cluster` directory now only contains playbooks that
include tasks from that role. This makes the structure much closer to
that of the AWS provider.
