Install Openstack With Ansible

IOWA repository

A set of roles to deploy openstack in a spread per component way

TODO LIST

• improve documentation !!!
• create a simple web ui to assign roles
• create a specific bridge mappings for compute nodes
• document cinder enabled backends
• add ldap support in keystone? keystone v3 ?
• document how to run the role with a custom variables files ( and with a specific component through tags)
• document that when creating a db, the corresponding hash with its associated dbuser, dbpassword and dbname is needed for mysql role to work correctly
• check if notifications_designate as topic is really needed or defaulting to notifications is enough

SOME TIPS AROUND CONF

CINDER

• volume_driver can be either
  • cinder.volume.drivers.lvm.LVMISCSIDriver . This is the default. In this case volume_group can be specified
  • cinder.volume.drivers.nfs.NfsDriver In this case , one can specify a different location and use the nfs_shares array to specify exports to add

NEUTRON

• grab tenant id and inject it in the conf
• set tunneling ip stuff and create br-tun

NOVA

• documento nova.novncproxy_url as it cant be set in defaults var file
• virt_type is qemu by default, you can set nova.virt_type to kvm if using nested ( it s giving some issues actually)

INSTALLING ON RHEL

note that those roles dont handle subscriptions also note that newton requires the rhel-7-server-openstack-10-devtools-rpms channel

RUN SPECIFIC COMPONENT

OVERRIDING VARIABLES

Either use extra-vars or a group_var directory

ansible-playbook init.yml --extra-vars "@samples/madrid.yaml"

ansible-playbook init.yml --tags keystone

DEPLOYING MULTIPLE NODES WITH ANSIBLE

• make the role visible

export ANSIBLE_ROLES_PATH=roles

• allinone

ansible-playbook -i ~/klist.py controller.yml

• api only

ansible-playbook -i ~/klist.py controller.yml --tags api

• controller stuff

ansible-playbook -i ~/klist.py site.yml --tags controller,mysql,rabbitmq,mongodb

• compute

ansible-playbook -i ~/klist.py compute.yml --tags compute

##RUNNING TESTS

testinfra --connection=ansible --ansible-inventory ~/klist.py --sudo --hosts=heat tests/test_heat.py  -v
