Sayantani Goswami 5b35e3898f Update Kolla-Ansible documents
Kolla-ansible related documents existed on both Kolla and Kolla-Ansible
repositories. A lot of Kolla-ansible related documents were updated in
the Kolla repository. Porting the changes made to these documents in
Kolla repo to Kolla-Ansible repo so that the Kolla-ansible documents can
be removed (Refer to patch https://review.openstack.org/#/c/425749/)

Prep host
=========
Clone kolla
-----------
::
git clone https://github.com/openstack/kolla
cd kolla
set up kolla dependencies :doc:`quickstart`
Fix hosts file
--------------
Docker bind mounts ``/etc/hosts`` into the container from a volume
This prevents atomic renames which will prevent ansible from fixing
the ``/etc/hosts`` file automatically.
To enable bifrost to be bootstrapped correctly add the deployment
hosts hostname to 127.0.0.1 line for example:
::
ubuntu@bifrost:/repo/kolla$ cat /etc/hosts
127.0.0.1 bifrost localhost
# The following lines are desirable for IPv6 capable hosts
::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts
192.168.100.15 bifrost
Enable source build type
========================
Via config file
---------------
::
tox -e genconfig
Modify ``kolla-build.conf`` as follows.
Set ``install_type`` to ``source``
::
install_type = source
Command line
------------
Alternatively if you do not wish to use the ``kolla-build.conf``
you can enable a source build by appending ``-t source`` to
your ``kolla-build`` or ``tools/build.py`` command.
Build container
===============
Development
-----------
::
tools/build.py bifrost-deploy
Production
----------
::
kolla-build bifrost-deploy
Prepare bifrost configs
=======================
Create servers.yml
------------------
The ``servers.yml`` will describing your physical nodes and list IPMI credentials.
See bifrost dynamic inventory examples for more details.
For example ``/etc/kolla/config/bifrost/servers.yml``
.. code-block:: yaml
---
cloud1:
uuid: "31303735-3934-4247-3830-333132535336"
driver_info:
power:
ipmi_username: "admin"
ipmi_address: "192.168.1.30"
ipmi_password: "root"
nics:
-
mac: "1c:c1:de:1c:aa:53"
-
mac: "1c:c1:de:1c:aa:52"
driver: "agent_ipmitool"
ipv4_address: "192.168.1.10"
properties:
cpu_arch: "x86_64"
ram: "24576"
disk_size: "120"
cpus: "16"
name: "cloud1"
adjust as appropriate for your deployment
Create bifrost.yml
------------------
By default kolla mostly use bifrosts default playbook values.
Parameters passed to the bifrost install playbook can be overridden by
creating a ``bifrost.yml`` file in the kolla custom config directory or in a
bifrost sub directory.
For example ``/etc/kolla/config/bifrost/bifrost.yml``
::
mysql_service_name: mysql
ansible_python_interpreter: /var/lib/kolla/venv/bin/python
network_interface: < add you network interface here >
# uncomment below if needed
# dhcp_pool_start: 192.168.2.200
# dhcp_pool_end: 192.168.2.250
# dhcp_lease_time: 12h
# dhcp_static_mask: 255.255.255.0
Create Disk Image Builder Config
--------------------------------
By default kolla mostly use bifrosts default playbook values when
building the baremetal os image. The baremetal os image can be customised
by creating a ``dib.yml`` file in the kolla custom config directory or in a
bifrost sub directory.
For example ``/etc/kolla/config/bifrost/dib.yml``
::
dib_os_element: ubuntu
Deploy Bifrost
=========================
Ansible
-------
Development
___________
::
tools/kolla-ansible deploy-bifrost
Production
__________
::
kolla-ansible deploy-bifrost
Manual
------
Start Bifrost Container
_______________________
::
docker run -it --net=host -v /dev:/dev -d --privileged --name bifrost_deploy kolla/ubuntu-source-bifrost-deploy:3.0.1
Copy configs
____________
.. code-block:: console
docker exec -it bifrost_deploy mkdir /etc/bifrost
docker cp /etc/kolla/config/bifrost/servers.yml bifrost_deploy:/etc/bifrost/servers.yml
docker cp /etc/kolla/config/bifrost/bifrost.yml bifrost_deploy:/etc/bifrost/bifrost.yml
docker cp /etc/kolla/config/bifrost/dib.yml bifrost_deploy:/etc/bifrost/dib.yml
Bootstrap bifrost
_________________
::
docker exec -it bifrost_deploy bash
Generate ssh key
~~~~~~~~~~~~~~~~
::
ssh-keygen
Source env variables
~~~~~~~~~~~~~~~~~~~~
::
cd /bifrost
. env-vars
. /opt/stack/ansible/hacking/env-setup
cd playbooks/
Bootstrap and start services
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
.. code-block:: console
ansible-playbook -vvvv -i /bifrost/playbooks/inventory/localhost /bifrost/playbooks/install.yaml -e @/etc/bifrost/bifrost.yml
Check ironic is running
=======================
.. code-block:: console
docker exec -it bifrost_deploy bash
cd /bifrost
. env-vars
Running "ironic node-list" should return with no nodes, for example
.. code-block:: console
(bifrost-deploy)[root@bifrost bifrost]# ironic node-list
+------+------+---------------+-------------+--------------------+-------------+
| UUID | Name | Instance UUID | Power State | Provisioning State | Maintenance |

Enroll and Deploy Physical Nodes
================================
Ansible
-------
Development
___________
::
tools/kolla-ansible deploy-servers
Production
__________
::
kolla-ansible deploy-servers
Manual
------
.. code-block:: console
docker exec -it bifrost_deploy bash
cd /bifrost
. env-vars
export BIFROST_INVENTORY_SOURCE=/etc/bifrost/servers.yml
ansible-playbook -vvvv -i inventory/bifrost_inventory.py enroll-dynamic.yaml -e "ansible_python_interpreter=/var/lib/kolla/venv/bin/python" -e network_interface=<provisioning interface>
docker exec -it bifrost_deploy bash
cd /bifrost
. env-vars
export BIFROST_INVENTORY_SOURCE=/etc/bifrost/servers.yml
ansible-playbook -vvvv -i inventory/bifrost_inventory.py deploy-dynamic.yaml -e "ansible_python_interpreter=/var/lib/kolla/venv/bin/python" -e network_interface=<prvisioning interface> -e @/etc/bifrost/dib.yml
At this point ironic should clean down your nodes and install the default
os image.
Advanced configuration
======================
Bring your own image
--------------------
TODO
Bring your own ssh key
----------------------
To use your own ssh key after you have generated the ``passwords.yml`` file
update the private and public keys under bifrost_ssh_key.
Known issues
============
SSH daemon not running
----------------------
By default sshd is installed in the image but may not be enabled.
If you encounter this issue you will have to access the server physically in
recovery mode to enable the ssh service. If your hardware supports it, this
can be done remotely with ipmitool and serial over lan. For example
.. code-block:: console
ipmitool -I lanplus -H 192.168.1.30 -U admin -P root sol activate
