Testing Openstack with Ansible and all-in-one install on Hyper-V

I installed Openstack recently in order to get my head around some aspects. I used my desktop (16GB RAM, decent chunk of SSD & i7-2600 @ 3.4GHz).

After looking at the 50 ways to install Openstack, I went with the developer ansible automation. Installation proceeded as follows.

Install Deployment Host

This contains the ansible configuration and drives the process.

Install Ubuntu as per requirements

Installed 14.04 (yes, it’s old. They may fix that soon.)

apt-get install aptitude build-essential git ntp ntpdate \
  openssh-server python-dev sudo

git clone -b stable/mitaka \
  https://github.com/openstack/openstack-ansible.git \
  /opt/openstack-ansible

scripts/bootstrap-ansible.sh

Networking assignments

Network	IP Range	VLAN
Host management	10.2.0.0/24	–
Container Management Network	172.29.236.0/22	10
Tunnel (VXLAN) Network	172.29.240.0/22	20
Storage Network	172.29.244.0/22	11

My numbering was

Host	Host mgmt	Container mgmt	Tunnel	Storage
deploy	10.2.0.40	172.29.236.1
Node1	10.2.0.50	172.29.236.101	172.29.240.101	172.29.244.101

Making Hyper-V connect up VLAN trunks that are run as bonded Ethernets

Hyper-v manager can’t set trunk mode on adapters so doing this with powershell run as administrator

Get-VM Deployment | Set-VMNetworkAdapterVlan -Trunk -AllowedVlanIdList 1-100 -NativeVlanId 0
Get-VM Node1 | Set-VMNetworkAdapterVlan -Trunk -AllowedVlanIdList 1-100 -NativeVlanId 0

Note – the NativeVlanId 0 is required to bridge this into the untagged management domain for the external network.

Also need to configure (Network Adapter | Advanced Features | MAC Address) to enable mac address spoofing (which the active/backup bonding will do)

Install Target Host

As per the docs and above. Could be improved by using MAAS but I won’t go there yet.

Configure networking

http://docs.openstack.org/developer/openstack-ansible/mitaka/install-guide/targethosts-networkrefarch.html

Did this by hand, but probably able to be skipped now that the ansible stuff generates this?

Deployment configuration questions – while configuring the yml and friends

Unsure that the network for neutron_linuxbridge_agent br-vlan has host_bind_override: “eth12” that is accurate. This is meant to be a physical interface as per http://docs.openstack.org/developer/openstack-ansible/mitaka/install-guide/configure-networking.html
Had to uncomment at least one thing in the user_variable.yml
Used the AIO templates for this all-in-one install.

Aged APT repo & keys… and figuring out that

Initially AOI failed in deployment due to untrusted packages; like a fool I tried hand-deploying the broken ones

apt-get install libasan0 libatomic1 libgomp1 libitm1 libc-dev-bin \
  linux-libc-dev libc6-dev libexpat1-dev libpython2.7-dev \
  libquadmath0 libtsan0 python3-libapparmor python3-pkg-resources \
  python3-apparmor apparmor-utils binutils cpp-4.8 libgcc-4.8-dev \
  gcc-4.8 libstdc++-4.8-dev g++-4.8 libdpkg-perl dpkg-dev \
  python2.7-dev python-software-properties

Running openstack-ansible setup-hosts.yml didn’t get me much further – failed again with security hardening – postfix install – so added added a no-authenticate in the yml files; not the right place though.

Stopped, thought, learnt and instead tried

apt-key update
apt-get update

Which (after agreeing to a key update from recollection) resolved the issues

Continuing on to manually run playbooks

openstack-ansible setup-hosts.yml
openstack-ansible setup-infrastructure.yml

Note the formating of the output of Ansible running the playbooks – should be no errors.

Confirmed with

ansible galera_container -m shell -a \
   "mysql -h localhost -e 'show status like \"%wsrep_cluster_%\";'"

Then finally installing openstack

openstack-ansible setup-openstack.yml

Wait something like an hour

It’s up!

Everything appeared to be running – but for Cinder volume block storage is down, probably because I my just have skipped some necessary LVM prep steps.
