From Ubuntu iso to openstack (All-In-One)

Ubuntu installation

Keyboard configuration

Use your favorite keyboard layout

Here: fr/fr

Choose type of install

Select Ubuntu Server (minimized) without checking “Search for third-party drivers”

Network configuration

ens18 can be dhcp or manual

ens19 must be disabled for now

Configure proxy

If you have a proxy to use, configure it, but here nope

Configure Ubuntu archive mirror

If you have a mirror @ home or cache, you can use it. Here we’ll use default mirror

Guided storage configuration

Do as you want, here I use default configuration without encryption

Storage configuration

ubuntu-lv must be resized to maximum size.

Profile setup

Do as you want

Upgrade to Ubuntu Pro

Do as you want, here I skip for now

SSH Setup

Install OpenSSH Server

You can import your ssh keys from GitHub or Launchpad.

Featured Server Snaps

DO NOT CHECK ANYTHING

Install complete

Wait for system update before reboot

After that, you can reboot and remove your bootable media.

Configure lvm partition

Fdisk

sudo fdisk /dev/<disk>

  1. n

  2. p

  3. ENTER

  4. ENTER

  5. t

  6. L

  7. Look at 8e, it must be LVM (if not, search for “Linux LVM”)

  8. Type 8e or new code

  9. p

  10. Look if it’s marked as “Linux LVM”

  11. w

Create cinder-volumes

  1. sudo pvcreate -f /dev/<disk>1

  2. sudo vgcreate -f cinder-volumes /dev/<disk>1

  3. Verify if all is ok with: sudo vgs

User rights

As default user, when you need privilege escalation, you need to type a password.

Ansible cannot know the password without telling him OR by modifying sudoers file.

sudo visudo

Put this:

leo ALL=(ALL:ALL) NOPASSWD:ALL

Networking

In /etc/netplan/00-installer-config.yaml:

# This is the network config written by 'subiquity'
network:
  ethernets:
    ens18:
      dhcp4: true
    ens19:
      dhcp4: false
      dhcp6: false
  version: 2

Deployment

kolla-ansible -i ./all-in-one bootstrap-servers && kolla-ansible -i ./all-in-one prechecks && kolla-ansible -i ./all-in-one deploy


Setup openstack cli


sudo pip install python-openstackclient -c https://releases.openstack.org/constraints/upper/master


kolla-ansible post-deploy && sudo cp /etc/kolla/clouds.yaml /etc/openstack && mkdir ~/.config && sudo cp /etc/kolla/clouds.yaml ~/ && sudo chown $USER:$USER clouds.yaml

Create “default” flavor

openstack --os-cloud kolla-admin flavor create --vcpus 1 --ram 512 --disk 1 m1.tiny && \
    openstack --os-cloud kolla-admin flavor create --vcpus 1 --ram 2048 --disk 20 m1.small && \
    openstack --os-cloud kolla-admin flavor create --vcpus 2 --ram 4096 --disk 40 m1.medium && \
    openstack --os-cloud kolla-admin flavor create --vcpus 4 --ram 8192 --disk 80 m1.large && \
    openstack --os-cloud kolla-admin flavor create --vcpus 8 --ram 16384 --disk 160 m1.xlarge

Reboot

Reboot after installation is better but not mandatory

Setup Network

Create basic public router

openstack --os-cloud kolla-admin router create router && \
openstack --os-cloud kolla-admin network create local-net && \
openstack --os-cloud kolla-admin subnet create --subnet-range 10.0.0.0/16 --network local-net --gateway 10.0.0.1 --dns-nameserver 8.8.8.8 local-subnet && \
openstack --os-cloud kolla-admin router add subnet router local-subnet && \
openstack --os-cloud kolla-admin network create --external --provider-physical-network physnet1 --provider-network-type flat public1 && \
openstack --os-cloud kolla-admin subnet create --allocation-pool start=10.1.2.150,end=10.1.2.199 --network public1 --subnet-range 10.1.2.0/24 --gateway 10.1.2.1 public1-subnet && \
openstack --os-cloud kolla-admin router set --external-gateway public1 router

Enable packet forwarding

Edit /etc/sysctl.conf 

net.ipv4.ip_forward=1
net.ipv4.conf.default.rp_filter=0
net.ipv4.conf.all.rp_filter=0

iptables command

sudo iptables -t nat -A POSTROUTING -o ens18 -j MASQUERADE

If you did not reboot your server, please enable the ens19 interface

sudo ip link set dev ens19 up

Testing installation
