Scaricare e installare l'ambiente:

git clone -b master https://opendev.org/openstack/openstack-ansible /opt/openstack-ansible
/opt/openstack-ansible/scripts/bootstrap-ansible.sh

Controllare /etc/hosts: non deve essere presente la entry 127.0.1.1, perché può generare problemi di risoluzione nomi. Lasciare invece 127.0.0.1

cp -dpR /opt/openstack-ansible/etc/openstack_deploy/* /etc/openstack_deploy
cp /etc/openstack_deploy/openstack_user_config.yml.example /etc/openstack_deploy/openstack_user_config.yml

Lavorare sui files:

• openstackuserconfig.yml: questo è un inventory in cui si dichiarano tute le parti fisiche e logiche coinvolte nel cluster (reti, host, gruppi, ruoli openstack es storage)
• uservariables.yml: variabili di configurazione * usersecrets.yaml: credenziali e password. Non va toccato a mano

= generare i secrets ==

cp -a /etc/openstack_deploy/user_secrets.yml /etc/openstack_deploy/user_secrets.yml.backup
/opt/openstack-ansible/scripts/pw-token-gen.py --file /etc/openstack_deploy/user_secrets.yml

source /opt/ansible-runtime/bin/activate
openstack-ansible-inventory --config /etc/openstack_deploy/
cat /etc/openstack_deploy/openstack_inventory.json

Per impostare la chiave ssh di default configurare /opt/openstack-ansible/ansible.cfg

[defaults]
private_key_file = ~/.ssh/id_ansible

Prima si usare ansible, eseguire

eval "$(ssh-agent -s)" && ssh-add ~/.ssh/id_ansible

• Preparazione degli hosts: openstack.osa.setuphosts - Installazione servizi non openstack: openstack.osa.setupinfrastructure
• Installazione servizi openstack: openstack.osa.setup_openstack

Prima di eseguire un playbook, si può controllare la presenza di errori:

openstack-ansible $PLAYBOOK --syntax-check

# openstack-ansible openstack.osa.setup_hosts
# openstack-ansible openstack.osa.setup_infrastructure

Verifica cluster mariadb (dopo il playbook openstack.osa.setup_infrastructure):

cd /opt/openstack-ansible
source /usr/local/bin/openstack-ansible.rc
ansible galera_container -m shell   -a "mariadb -h localhost -e 'show status like \"%wsrep_cluster_%\";'"

openstack-ansible openstack.osa.setup_openstack
