How to specify host specific parameters (for example, the interface names are different for the different servers in the cluster)?
Resolution: Check the example here.

Resolution:: This is a result of the recent change done via Bug #1756133 There is a use-case where vrouter needs to be provisioned without being accompanied by nova-compute. So the "openstack_compute" is not automatically inferred when "vrouter" role is specified. The "openstack_compute" role needs to be explicitly stated along with "vrouter"

By default all openstack services will listen on the IP/interface provided by kolla_internal_vip_address/network_interface variables under the "kolla_globals" section. This will in most cases correspond to the ctrl-data network. Note that this will mean even horizon will now only run on ctrl-data network only. The only way kolla provides access to horizon on the management network is by using haproxy and keepalived. Enabling keepalived in turn means that a virtual IP is required for VRRP which cannot be the interface IP itself. There is no way to enable haproxy without enabling keepalived using kolla configuration parameters. This is the reason you need to provide two virtual IP address one on management (kolla_external_vip_address) and one on ctrl-data-network (kolla_internal_vip_address). Once this is given, horizon will be accessible on the management network via the kolla_external_vip_address.

The /etc/kolla/kolla-toolbox directory of the base host on which openstack containers are running is mounted and accessible as /var/lib/kolla/config_files from inside the kolla_toolbox container. In case the user needs other files when executing openstack commands (for example 'openstack image create' will need image file), then the user can copy the relevant files into the /etc/kolla/kolla-toolbox directory of the base host and then use them inside the container. The way to run openstack commands is as follows:
# ON BASE HOST OF OPENSTACK CONTROL NODE cd /etc/kolla/kolla-toolbox wget http://download.cirros-cloud.net/0.4.0/cirros-0.4.0-x86_64-disk.img docker exec -it kolla_toolbox bash # NOW YOU ARE INSIDE THE KOLLA_TOOLBOX CONTAINER (kolla-toolbox)[ansible@server1 /]$ source /var/lib/kolla/config_files/admin-openrc.sh (kolla-toolbox)[ansible@server1 /]$ cd /var/lib/kolla/config_files (kolla-toolbox)[ansible@server1 /var/lib/kolla/config_files]$ openstack image create cirros2 --disk-format qcow2 --public --container-format bare --file cirros-0.4.0-x86_64-disk.img +------------------+------------------------------------------------------+ | Field | Value | +------------------+------------------------------------------------------+ | checksum | 443b7623e27ecf03dc9e01ee93f67afe | | container_format | bare | | created_at | 2018-03-29T21:37:48Z | | disk_format | qcow2 | | file | /v2/images/e672b536-0796-47b3-83a6-df48a5d074be/file | | id | e672b536-0796-47b3-83a6-df48a5d074be | | min_disk | 0 | | min_ram | 0 | | name | cirros2 | | owner | 371bdb766278484bbabf868cf7325d4c | | protected | False | | schema | /v2/schemas/image | | size | 12716032 | | status | active | | tags | | | updated_at | 2018-03-29T21:37:50Z | | virtual_size | None | | visibility | public | +------------------+------------------------------------------------------+ (kolla-toolbox)[ansible@server1 /var/lib/kolla/config_files]$ openstack image list +--------------------------------------+---------+--------+ | ID | Name | Status | +--------------------------------------+---------+--------+ | e672b536-0796-47b3-83a6-df48a5d074be | cirros2 | active | | 57e6620e-796a-40ee-ae6e-ea1daa253b6c | cirros2 | active | +--------------------------------------+---------+--------+ -

Resolution: This is caused by code incompatible with 2.5.1.0 version of Ansible. Please stick to ansible-2.4.2.0 to avoid this issue for now until we fix the code to work with the latest version of Ansible.
