Adds a new svc-map element which can be used to install services based on an in element 'svc-map' YAML config file format. This change is intended to decouple elements from DIB and allow new elements to support multiple distributions (with various service naming schemes) without having to constantly maintain DIB's various bin/map-services files. This patch ensures all of the YAML files are compiled into a single file without namespaces. The YAML compilation process occurs during image creation time and errors if conflicting mappings are found. Change-Id: Id11433ea342aace71a358936a7ca3151ec11d506

Map service names to distro specific services.
|
|
|
|
Provides the following:
|
|
|
|
* bin/svc-map
|
|
|
|
usage: svc-map [-h] SERVICE
|
|
|
|
Translate service name to distro specific name.
|
|
|
|
optional arguments:
|
|
-h, --help show this help message and exit
|
|
|
|
* Any element may create its own svc-map YAML config file using
|
|
the one of 3 sections for the distro/family/ and or default.
|
|
The family is set automatically within svc-map based on
|
|
the supplied distro name. Families include:
|
|
+ redhat: includes centos, fedora, and rhel distros
|
|
+ debian: includes debian and ubuntu distros
|
|
+ suse: includes the opensuse distro
|
|
|
|
The most specific section takes priority. Example for Nova and Glance
|
|
(NOTE: default is using the common value for redhat and suse families)
|
|
|
|
The key used for the service name should always be the same name used for
|
|
the source installation of the service. The svc-map script will check for
|
|
the source name against systemd and upstart and return that name if it
|
|
exists instead of the mapped name.
|
|
|
|
Example format for Nova:
|
|
|
|
nova-api:
|
|
default: openstack-nova-api
|
|
debian: nova-api
|
|
nova-cert:
|
|
default: openstack-nova-cert
|
|
debian: nova-cert
|
|
nova-compute:
|
|
default: openstack-nova-compute
|
|
debian: nova-compute
|
|
nova-conductor:
|
|
default: openstack-nova-conductor
|
|
debian: nova-conductor
|
|
nova-consoleauth:
|
|
default: openstack-nova-console
|
|
debian: nova-console
|
|
|
|
|
|
Example format for Glance
|
|
|
|
glance-api:
|
|
debian: glance-api
|
|
default: openstack-glance-api
|
|
glance-reg:
|
|
debian: glance-reg
|
|
default: openstack-glance-registry
|
|
|
|
|
|
If the distro is of the debian family the combined services file would be:
|
|
|
|
nova-cert: nova-cert
|
|
nova-compute: nova-compute
|
|
glance-api: glance-api
|
|
nova-conductor: nova-conductor
|
|
nova-api: nova-api
|
|
glance-reg: glance-reg
|
|
nova-consoleauth: nova-console
|
|
|
|
|
|
If the distro is of the suse or redhat families the combined services file would be:
|
|
|
|
nova-cert: openstack-nova-cert
|
|
nova-compute: openstack-nova-compute
|
|
glance-reg: openstack-glance-registry
|
|
nova-conductor: openstack-nova-conductor
|
|
glance-api: openstack-glance-api
|
|
nova-consoleauth: openstack-nova-console
|
|
nova-api: openstack-nova-api
|
|
|
|
|
|
Example commands using this format:
|
|
|
|
svc-map nova-compute
|
|
|
|
Returns: openstack-nova-compute
|
|
|
|
svc-map nova-compute
|
|
|
|
Returns: openstack-nova-compute
|
|
|
|
svc-map nova-compute
|
|
|
|
Returns: nova-compute
|

* This output can be used to filter what other tools actually install
|
|
(install-services can be modified to use this for example)
|
|
|
|
* If you pass more than one service argument, the result for each service
|
|
is printed on its own line.
|
|
|
|
* Individual svc-map files live within each element. For example
|
|
if you have created an Apache element your svc-map YAML file
|
|
should be created at elements/apache/svc-map.
