Dmitriy Rabotyagov 9a39e22b0f Remove mention of haproxy-endpoints role

Role was never migrated to usage of haproxy-endpoints role
and included task was used instead the whole time.
With that to reduce complexity and to have unified approach, all mention
of the role and handler are removed from the code.

Zun role for OpenStack-Ansible

configure-zun.rst app-powervm.rst

tags: openstack, zun, cloud, ansible
category: *nix

This role will install the following Systemd services:

zun-server
zun-compute

To clone or view the source code for this repository, visit the role repository for os_zun.

Default variables

../../defaults/main.yml

Dependencies

This role needs pip >= 7.1 installed on the target host.

Example playbook

../../examples/playbook.yml

CPU platform compatibility

This role supports multiple CPU architecture types. At least one repo_build node must exist for each CPU type that is in use in the deployment.

Currently supported CPU architectures:

x86_64 / amd64
ppc64le

At this time, ppc64le is only supported for the Compute node type. It can not be used to manage the OpenStack-Ansible management nodes.

Compute driver compatibility

This role supports multiple zun compute driver types. The following compute drivers are supported:

libvirt (default)
ironic
lxd (via zun-lxd)
powervm (via zun-powervm)

The driver type is automatically detected by the OpenStack Ansible Nova role for the following compute driver types:

libvirt (kvm / qemu)
powervm

Any mix and match of compute node types can be used for those platforms, except for ironic.

If using the lxd driver, the compute type must be specified using the zun_virt_type variable.

The zun_virt_type may be set in /etc/openstack_deploy/user_variables.yml, for example:

zun_virt_type: lxd

You can set zun_virt_type per host by using host_vars in /etc/openstack_deploy/openstack_user_config.yml. For example:

compute_hosts:
 aio1:
   ip: 172.29.236.100
   host_vars:
     zun_virt_type: lxd

If zun_virt_type is set in /etc/openstack_deploy/user_variables.yml, all nodes in the deployment are set to that hypervisor type. Setting zun_virt_type in both /etc/openstack_deploy/user_variables.yml and /etc/openstack_deploy/openstack_user_config.yml will always result in the value specified in /etc/openstack_deploy/user_variables.yml being set on all hosts.
