Examples and usage

Most of the variable are present in all.yml and can be overridden by the --extra-vars="" flag

source overcloudrc

##Post deployment tasks Command: ansible-playbook overcloud-postdeploy.yaml

Results: - Creation of flat provider network associated with libvirt net-external physical network - Creation of associated public subnet - Creation of private network and subnet - creation of a router with one leg in each of the nets created earlier

Command:

ansible-playbook images-sg-keys.yaml

Results:

• Creation of flavors, images, security groups and keys

Command:

ansible-playbook create-provider-network-vlan.yaml  --extra-vars="segmentation=x"

Results:

- Creation of  vlan provider network and associated subnet

  Change: cidr: and  gateway_ip: to fit your env

Instance creation and cloudinit examples

Commands:

ansible-playbook instance-provider.yaml

Results:

• Creation of an instance connected to provider network with volume attached, formated and mounted

• Cloudinit is being used to se t hostname, fqdn and upgrade packages

  #cloud-config hostname: provider-{{ segmentation }} fqdn: provider-{{ segmentation }}.lab.local manage_etc_hosts: true debug: true package_upgrade: true

  • Create users, change passww, inject ssh keys, format and mount volume

    users: - default - name: stack sudo: ["ALL=(ALL) NOPASSWD:ALL"] groups: wheel,adm ssh_pwauth: True ssh_authorized_keys: - {{IDRSAPUB}} - name: root ssh_authorized_keys: - {{IDRSAPUB}} ssh_pwauth: True disable_root: false chpasswd: list: | root:toor stack:stack expire: false packages: - tmux - git fs_setup: - label: None filesystem: 'ext4' device: '/dev/vdc' partition: 'auto'

    mounts:

           - [ /dev/vdc, /volume-makina-{{image}}, "ext4", "defaults,noatime"]
    
          mount_default_fields: [ None, None, "ext4", "defaults,noatime", "0","2" ]
