Nolan Brubaker 7431aafa86 Document required repository hosts config info
Installs must have either the repo-infra_hosts list, or the
openstack_repo_url defined. Otherwise, greenfield installations
following our installation docs will fail.

Configuring target hosts
------------------------
Modify the ``/etc/openstack_deploy/openstack_user_config.yml`` file to
configure the target hosts.
Do not assign the same IP address to different target hostnames.
Unexpected results may occur. Each IP address and hostname must be a
matching pair. To use the same host in multiple roles, for example
infrastructure and networking, specify the same hostname and IP in each
section.
Use short hostnames rather than fully-qualified domain names (FQDN) to
prevent length limitation issues with LXC and SSH. For example, a
suitable short hostname for a compute host might be:
``123456-Compute001``.
#. Configure a list containing at least three infrastructure target
hosts in the ``infra_hosts`` section:
.. code-block:: yaml
infra_hosts:
603975-infra01:
ip: INFRA01_IP_ADDRESS
603989-infra02:
ip: INFRA02_IP_ADDRESS
627116-infra03:
ip: INFRA03_IP_ADDRESS
628771-infra04: ...
Replace ``*_IP_ADDRESS`` with the IP address of the ``br-mgmt``
container management bridge on each infrastructure target host. Use
the same net block as bond0 on the nodes, for example:
.. code-block:: yaml
infra_hosts:
603975-infra01:
ip: 10.240.0.80
603989-infra02:
ip: 10.240.0.81
627116-infra03:
ip: 10.240.0.184
#. Configure a list containing at least one network target host in the
``network_hosts`` section:
.. code-block:: yaml
network_hosts:
602117-network01:
ip: NETWORK01_IP_ADDRESS
602534-network02: ...
Replace ``*_IP_ADDRESS`` with the IP address of the ``br-mgmt``
container management bridge on each network target host.
#. Configure a list containing at least one compute target host in the
``compute_hosts`` section:
.. code-block:: yaml
compute_hosts:
900089-compute001:
ip: COMPUTE001_IP_ADDRESS
900090-compute002: ...
Replace ``*_IP_ADDRESS`` with the IP address of the ``br-mgmt``
container management bridge on each compute target host.
#. Configure a list containing at least one logging target host in the
``log_hosts`` section:
.. code-block:: yaml
log_hosts:
900088-logging01:
ip: LOGGER1_IP_ADDRESS
903877-logging02: ...
Replace ``*_IP_ADDRESS`` with the IP address of the ``br-mgmt``
container management bridge on each logging target host.
#. Configure a list containing at least one repository target host in the
``repo-infra_hosts`` section:
.. code-block:: yaml
repo-infra_hosts:
603975-repo01:
ip: REPO01_IP_ADDRESS
603989-repo02:
ip: REPO02_IP_ADDRESS
627116-repo03:
ip: REPO03_IP_ADDRESS
628771-repo04: ...
Replace ``*_IP_ADDRESS`` with the IP address of the ``br-mgmt``
container management bridge on each repository target host.
The repository typically resides on one or more infrastructure hosts.
Alternatively, specify a value for the ``openstack_repo_url`` variable
in the ``/etc/openstack_deploy/user_group_vars.yml`` file. The value should
contain a URL for a host with the appropriate repository layout. For
example:
.. code-block:: yaml
openstack_repo_url: "https://rpc-repo.rackspace.com/"
Using ``repo-infra_hosts`` configures a local repository with the
appropriate layout and sets ``openstack_repo_url`` for you.
#. Configure a list containing at least one optional storage host in the
``storage_hosts`` section:
.. code-block:: yaml
storage_hosts:
100338-storage01:
ip: STORAGE01_IP_ADDRESS
100392-storage02: ...
Replace ``*_IP_ADDRESS`` with the IP address of the ``br-mgmt``
container management bridge on each storage target host. Each storage
host also requires additional configuration to define the back end
driver.
The default configuration includes an optional storage host. To
install without storage hosts, comment out the stanza beginning with
the *storage\_hosts:* line.
