+=== packages ctrl ansible ===
+<code>
+apt update
+apt dist-upgrade
+reboot
+apt install build-essential git chrony openssh-server python3-dev sudo
+</code>
+=== Setup openstack  ansible ===
+Scaricare e installare l'ambiente:
+<code>
+git clone -b master https://opendev.org/openstack/openstack-ansible /opt/openstack-ansible
+/opt/openstack-ansible/scripts/bootstrap-ansible.sh
+</code>
+==== HOSTS ====
+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
+<code>
+apt update
+apt dist-upgrade
+apt install bridge-utils debootstrap openssh-server \
+  tcpdump vlan python3
+apt install linux-modules-extra-$(uname -r)
+reboot
+</code>
+===== Ansible =====
+<code>
+cp -dpR /opt/openstack-ansible/etc/openstack_deploy/* /etc/openstack_deploy
+cp /etc/openstack_deploy/openstack_user_config.yml.example /etc/openstack_deploy/openstack_user_config.yml
+</code>
+Lavorare sui files:
+  * openstack_user_config.yml: questo è un inventory in cui si dichiarano tute le parti fisiche e logiche coinvolte nel cluster (reti, host, 	gruppi, ruoli openstack es storage)
+  * user_variables.yml: variabili di configurazione
+  * user_secrets.yaml: credenziali e password. Non va toccato a mano
+= generare i secrets ==
+<code>
+cp -a /etc/openstack_deploy/user_secrets.yml /etc/openstack_deploy/user_secrets.yml.backup
+/opt/openstack-ansible/scripts/pw-token-gen.py --file /etc/openstack_deploy/user_secrets.yml
+</code>
+=== Creare l'inventory ===
+<code>
+source /opt/ansible-runtime/bin/activate
+openstack-ansible-inventory --config /etc/openstack_deploy/
+cat /etc/openstack_deploy/openstack_inventory.json
+</code>
+=== Chiave ssh ===
+Per impostare la chiave ssh di default configurare /opt/openstack-ansible/ansible.cfg
+<code>
+[defaults]
+private_key_file = ~/.ssh/id_ansible
+</code>
+Prima si usare ansible, eseguire
+<code>
+eval "$(ssh-agent -s)" && ssh-add ~/.ssh/id_ansible
+</code>
+=== Playbooks ===
+  -  Preparazione degli hosts: ''openstack.osa.setup_hosts''
+  -  Installazione servizi non openstack: ''openstack.osa.setup_infrastructure''
+  -  Installazione servizi openstack: ''openstack.osa.setup_openstack''
+Prima di eseguire un playbook, si può controllare la presenza di errori:
+<code>
+openstack-ansible $PLAYBOOK --syntax-check
+</code>
+== Installazione ==
+<code>
+# openstack-ansible openstack.osa.setup_hosts
+# openstack-ansible openstack.osa.setup_infrastructure
+</code>
+Verifica cluster mariadb (dopo il playbook openstack.osa.setup_infrastructure):
+<code>
+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_%\";'"
+</code>
+== playbvook deploy openstack ==
+<code>
+openstack-ansible openstack.osa.setup_openstack
+</code>
