======Openstack with Kolla on CentOS 7======
=====Topology=====
I am going to build a multinode Openstack environment. I use an HP DL320e with Core a i3 and 16GB of memory as my controller node. The minimum requirements for running a controller is 8GB of memory and trust me, it uses it all!
I use an HP DL320e with a E3-1241v3 and 32GB of memory as my compute node.
As deploy node on which Kolla software is installed I use a VM with 2GB memory and 4 vCPUs.
I am going to use my Synology as NFS storage. Openstack uses NFSv4 so it really does not matter what kind of NAS you use.

=====Base installation=====
Use my [[docker_host_on_centos_7|Docker host on CentOS 7]] howto on every host.

=====Disable SELinux=====
I hate to disable SElinux but SELinux and Kolla is a work in progress. At the moment it does not work very well, so we have to disable it the hosts we are going to deploy it on. In this case not on the Kolla VM.
<code - /etc/selinux/config>
.
.
SELINUX=disabled
.
.
</code>
=====Disable Firewalld=====
For the moment I am going to disable firewalld because I do not know the used ports yet....
  systemctl disable firewalld
=====Docker repository=====
The Kolla server needs to be a Docker repository for all the Docker containers.
  yum -y install docker-distribution

Create SSL key and csr and sign it using your own CA. Put them in the place defined in the config.yml
<code - /etc/docker-distribution/registry/config.yml>
.
.
http:
    addr: :5000
    tls:
        certificate: "/etc/pki/tls/certs/kolla.mngt.bh.helux.nl.crt"
        key: "/etc/pki/tls/private/kolla.mngt.bh.helux.nl.key"
</code>

Create an LV for the repository
  lvcreate -L16G -n registry /dev/rootvg
  mkfs.ext4 -m0 /dev/rootvg/registry

<code - /etc/fstab>
.
.
/dev/mapper/rootvg-docker /var/lib/registry ext4 defaults,noatime,discard 1 2
</code>
  mount -a

  systemctl start docker-distribution
  systemctl enable docker-distribution.service

Test the connection on the other hosts. Output should be:
  curl https://kolla.mngt.bh.helux.nl:5000/v2

  <a href="/v2/">Moved Permanently</a>.
=====Prerequisites for Kolla=====
  yum -y install python-pip python-docker-py ansible python-devel libffi-devel gcc openssl-devel

  pip install -U pip

  pip install -U python-openstackclient python-neutronclient python-designateclient

=====Install Kolla=====
  pip install kolla
  pip install kolla-ansible

  cp -r /usr/share/kolla-ansible/etc_examples/kolla /etc/

=====Configure Kolla=====
Compare the original with my globals.yml and edit to your needs.
<code - /etc/kolla/globals.yml>

###############################
# This interface is what all your api services will be bound to by default.
# Additionally, all vxlan/tunnel and storage network traffic will go over this
# interface by default. This interface must contain an IPv4 address.
# It is possible for hosts to have non-matching names of interfaces - these can
# be set in an inventory file per host or per group or stored separately, see
#     http://docs.ansible.com/ansible/intro_inventory.html
# Yet another way to workaround the naming problem is to create a bond for the
# interface on all hosts and give the bond name here. Similar strategy can be
# followed for other types of interfaces.
network_interface: "vlan2"

# These can be adjusted for even more customization. The default is the same as
# the 'network_interface'. These interfaces must contain an IPv4 address.

# This is the raw interface given to neutron as its external network port. Even
# though an IP address can exist on this interface, it will be unusable in most

====Profiles====
I do not want to build all Openstack containers, so I have created my own profile
<code - /etc/kolla/kolla-build.conf>
[DEFAULT]
output_file = etc/kolla/kolla-build.conf
namespace = kolla

[profiles]

# Infra images (list value)
#infra = ceph,cron,mariadb,haproxy,keepalived,kolla-toolbox,memcached,mongodb,openvswitch,rabbitmq,heka

</code>
====Passwords====
Next we have to put the password framework file in place. Kolla generates passwords for you and puts them in here.
  cp /usr/share/kolla-ansible/etc_examples/kolla/passwords.yml /etc/kolla
Now run the command to generate them
  kolla-genpwd
=====Build the Kolla containers=====
This takes some time so run it in a screen if your connection to the server is poor.
  kolla-build --base centos --type binary --profile helux --registry kolla.mngt.bh.helux.nl:5000 --push
When done. You must see something like this:
  docker images

=====Additional configuration=====
====Ansible templates====
We need to alter an ansible template of Kolla to enable multi domains in Horizon

<code - /usr/share/kolla-ansible/ansible/roles/horizon/templates/local_settings.j2>
.
.
#OPENSTACK_KEYSTONE_MULTIDOMAIN_SUPPORT = False
OPENSTACK_KEYSTONE_MULTIDOMAIN_SUPPORT = True
.
.
</code>

====Kolla configuration directory====
The ansible scripts use the /etc/kolla directory to configure customer specific parts of Openstack.
  mkdir -p /etc/kolla/config/keystone/domains
===Own signed certificates===
  mkdir /etc/kolla/certificates
Create haproxy-ca.pem containg root CA certificate and create haproxy.pem containing the private key and certificate concatenated.
<code>
ls -l /etc/kolla/certificates/
total 8
-rw-r--r-- 1 root root 1192 Jun 20 17:44 haproxy-ca.pem
-rw-r----- 1 root root 2205 Jun 20 18:18 haproxy.pem
</code>
I use NFS storage so create a file with the NFS share info. 
<code - /etc/kolla/config/nfs_shares.j2>
172.16.2.2:/volume1/cinder
</code>
<code - /etc/kolla/config/nova.conf>
[DEFAULT]
cpu_allocation_ratio = 16.0
ram_allocation_ratio = 1.5
disk_allocation_ratio = 9999.0
block_device_allocate_retries = 300
block_device_allocate_retries_interval = 10
block_device_creation_timeout = 300
</code>
We are going to deploy on multiple nodes so copy the example over
  cp /usr/share/kolla-ansible/ansible/inventory/multinode /etc/kolla/
Change matching environment:
<code - /etc/kolla/multinode>
[control]
# These hostname must be resolvable from your deployment host
hp1
.
.
[network]
hp1
.
[compute]
hp2
.
[monitoring]
hp1
.
.
[storage]
hp1
</code>


====Synology and Cinder====
Yes that is right! Some Synology models have Openstack Cinder Volume plugin capabilities.
I have created a Cinder conf file and I have added the nfs-1 backend, which is created by the nfs j2 file.
<code - /etc/kolla/config/cinder.conf>
[DEFAULT]
enabled_backends = iscsi-volume1,iscsi-volume2,nfs-1
default_volume_type = iscsi-volume1

[iscsi-volume1]
volume_driver = cinder.volume.drivers.synology.synology_iscsi.SynoISCSIDriver
volume_backend_name = iscsi-volume1
iscs_protocol = iscsi
iscsi_ip_address = 172.16.2.2
synology_admin_port = 5001
driver_use_ssl = True
synology_ssl_verify = False
synology_username = admin
synology_password = "PASSWORD"
synology_pool_name = volume1

[iscsi-volume2]
volume_driver = cinder.volume.drivers.synology.synology_iscsi.SynoISCSIDriver
volume_backend_name = iscsi-volume2
iscs_protocol = iscsi
iscsi_ip_address = 172.16.2.2
synology_admin_port = 5001
driver_use_ssl = True
synology_ssl_verify = False
synology_username = admin
synology_password = "PASSWORD"
synology_pool_name = volume2
</code>
====Keystone LDAP domain====
<code - /etc/kolla/config/keystone/domains/keystone.helux.conf>
[identity]
driver = ldap

[resource]
driver = sql

[assignment]
driver = sql

[role]
driver = sql

[ldap]
url = ldap://ldap.mngt.bh.helux.nl
suffix = dc=helux,dc=nl
query_scope = sub
user = cn=manager,dc=helux,dc=nl
password = 'PASSWORD'
use_dumb_member = False

user_tree_dn = ou=people,dc=helux,dc=nl
user_objectclass = inetOrgPerson

user_id_attribute = cn
user_name_attribute = cn
#user_mail_attribute = mail
#user_pass_attribute = userPassword
#user_enabled_attribute =

group_tree_dn = ou=group,dc=helux,dc=nl
group_objectclass = groupOfUniqueNames
group_id_attribute = cn
group_name_attribute = cn
group_member_attribute = uniqueMember
#group_desc_attribute = description

user_allow_create = false
user_allow_update = false
user_allow_delete = false
project_allow_create = false
project_allow_update = false
project_allow_delete = false
role_allow_create = false
role_allow_update = false
role_allow_delete = false
group_allow_create = false
group_allow_update = false
group_allow_delete = false
</code>

=====Deploy Docker containers=====
====SSH keys====
Kolla needs password-less root access to the nodes. As root user:
  ssh-keygen
  ssh-copy-id hp1
  ssh-copy-id hp2
====Pre-checks====
  kolla-ansible prechecks -i /etc/kolla/multinode
====Deploy====
Sometimes fluentd container check hangs... Ctrl-C the deploy command and do it again, no pre-checks
  kolla-ansible deploy -i  /etc/kolla/multinode
When deployment is done you will see something like this:
<code>
PLAY RECAP *********************************************************************
hp1                        : ok=284  changed=134  unreachable=0    failed=0
hp2                        : ok=68   changed=26   unreachable=0    failed=0
</code>
We can go to post deploy now.
====Cleanup====
When deploying on other nodes or deploying again:
  /usr/share/kolla-ansible/tools/cleanup-containers
  /usr/share/kolla-ansible/tools/cleanup-host
=====Post deploy=====
  kolla-ansible post-deploy
  . /etc/kolla/admin-openrc.sh
Now Kolla comes with an initial setup script. We need to alter it a little bit to the network config we have.
<code - /usr/share/kolla-ansible/init-runonce>

After it is altered to your needs, run it!
  /usr/share/kolla-ansible/init-runonce
Get the admin password out of the passwords.yml
  grep keystone_admin /etc/kolla/passwords.yml
  keystone_admin_password: <STRING>
Use the <STRING> to login to Horizon Dashboard. In my case: [[http://cloud.mngt.bh.helux.nl]]
=====When stuff is running=====
====Multiple storage backends====
Run from Kolla deploy host:
<code>
cinder type-create nfs-1
cinder type-key nfs-1 set volume_backend_name=nfs-1
cinder type-create iscsi-volume1
cinder type-create iscsi-volume2
cinder type-key iscsi-volume1 set volume_backend_name=iscsi-volume1
cinder type-key iscsi-volume2 set volume_backend_name=iscsi-volume2
cinder type-list
cinder extra-specs-list
</code>
====Bug in LDAP module of keystone====
Run from controller host:
<code>
docker exec -ti -u0 keystone bash
cd /usr/lib/python2.7/site-packages/keystone/identity/backends/ldap
mv core.py core.py.org
curl https://git.openstack.org/cgit/openstack/keystone/plain/keystone/identity/backends/ldap/core.py?id=4e0029455ab45e3b9a15fe9fc151c14c502b7bdd -o core.py
</code>
====Create domain====
Run from Kolla deploy host:
  openstack domain create helux
  docker restart keystone
Login with valid user on domain helux in Horizon. You will get the error 'You are not authorized for any projects or domains.' 

Run from controller host:
  docker exec -ti -u0 mariadb bash
  mysql -u keystone -p
  use keystone;
<code>
MariaDB [keystone]> select * from id_mapping;
+------------------------------------------------------------------+----------------------------------+----------+-------------+

Now we can add the LDAP user to the domain as admin

Run from kolla deploy host:
  openstack role add --domain helux --user 6b647e1415bf57d15eda4200586059a9f5839994c9aeb03b4e7a6487244ecca4 admin
