UPDATE: Fixed Cinder, Heat and Ironic generate_sample.sh commands. Thanks Mike Spreitzer.

Each OpenStack project is a bit different. One of those differences is how sample config files are managed (or not) in the repository.

Here is a summary about how each project manage them.

Ceilometer

Ceilometer does not provide any sample config file in its repository.

To generate the sample config file, execute the following command:

tox -egenconfig

The sample config file will be located here:

./etc/ceilometer/ceilometer.conf.sample

Cinder

Cinder provides a sample config file in its repository.

The sample config file can be found here:

./etc/cinder/cinder.conf.sample

To (re)generate the sample config file, execute the following command:

tox -egenconfig

Beforethis change got merged, you had to execute the following command:

tox -evenv -- bash ./tools/config/generate_sample.sh -b . -p cinder -o etc/cinder

Glance

Glance provides multiple sample config files in its repository.

The sample config files can be found here:

./etc/glance/glance-api.conf./etc/glance/glance-cache.conf./etc/glance/glance-registry.conf./etc/glance/glance-scrubber.conf

The current oslo.config.generator does not support configs being split in multiple config files. Therefore, they cannot not be regenerated.Someone already reportedthis limitation in oslo.config on Launchpad.

Julien Danjou recently suggestedunifying all Glance config files into a single one.A blueprint already existsabout it.

Heat

Heat provides a sample config file in its repository.

The sample config file can be found here:

./etc/heat/heat.conf.sample

To (re)generate the sample config file, execute the following command:

tox -evenv -- bash ./tools/config/generate_sample.sh -b . -p heat -o etc/heat

Horizon

Horizon provides a sample config file in its repository.

The sample config file can be found here:

openstack_dashboard/local/local_settings.py.example

The sample config file does not use oslo.config and cannot be regenerated, it is manually updated.

Radomir Dopieralski proposesusing oslo.config to manage Horizon configs. Thanks toTom Fifield for pointing that one outon the openstack-operators mailinglist.

Ironic

Ironic provides a sample config file in its repository.

The sample config file can be found here:

./etc/ironic/ironic.conf.sample

To (re)generate the sample config file, execute the following command:

tox -egenconfig

Beforethis change got merged, you had to execute the following command:

tox -evenv -- bash ./tools/config/generate_sample.sh -b . -p ironic -o etc/ironic

Keystone

Keystone does not provide any sample config file in its repository.

To generate the sample config file, execute the following command:

tox -esample_config

The sample config file will be located here:

./etc/keystone/keystone.conf.sample

Neutron

Neutron provides multiple sample config files in its repository.

The sample config files can be found here:

./etc/dhcp_agent.ini./etc/fwaas_driver.ini./etc/l3_agent.ini./etc/lbaas_agent.ini./etc/metadata_agent.ini./etc/metering_agent.ini./etc/neutron.conf./etc/services.conf./etc/vpn_agent.ini./etc/plugins/*

The current oslo.config.generator does not support configs being split in multiple config files. Therefore, they cannot not be regenerated.Someone already reportedthis limitation in oslo.config on Launchpad.

Note thata blueprint existssuggesting the sample config files should be removed in favor of auto-generated ones like Nova already does.

Nova

Nova does not provide any sample config file in its repository.

To generate the sample config file, execute the following command:

tox -egenconfig

The sample config file will be located here:

./etc/nova/nova.conf.sample

Swift

Swift provides multiple sample config files in its repository.

The sample config files can be found here:

./etc/account-server.conf-sample./etc/container-server.conf-sample./etc/dispersion-server.conf-sample./etc/driver-audit.conf-sample./etc/memcache.conf-sample./etc/object-expirer.conf-sample./etc/object-server.conf-sample./etc/proxy-server.conf-sample./etc/swift-bench.conf-sample./etc/swift.conf-sample

Swift does not use oslo.config. Sample config files cannot be regenerated, they are manually updated.
