Helpers for writing Snaps for OpenStack

This project provides a wrapper for automatically wrapping openstack commands in snaps, building out appropriate Oslo configuration and logging options on the command line.

This wrapper is used by including a snap-openstack.yaml configuration file into the root of a snap.

Setup is executed for all entry points prior to execution snap-openstack will assure that templated files are in place and that any directory structure in $SNAP_COMMON is created.

setup:
  dirs:
    - "{snap_common}/etc/nova.conf.d"
    - "{snap_common}/etc/nova"
    - "{snap_common}/logs"
  templates:
    "nova-snap.conf.j2": "{snap_common}/etc/nova.conf.d/nova-snap.conf"

snap-openstack.yaml should also declare entry points for the snap:

entry_points:
  nova-manage:
    binary: nova-manage
    config-files:
      - "{snap}/etc/nova/nova.conf"
      - "{snap_common}/etc/nova/nova.conf"
    config-dirs:
      - "{snap_common}/etc/nova.conf.d"
    log-file: "{snap_common}/logs/nova-manage.log"

Executes the following:

nova-manage --config-file=$SNAP/etc/nova/nova,conf \
            --config-file=$SNAP_COMMON/etc/nova/nova.conf \
            --config-dir=$SNAP_COMMON/etc/nova.conf.d \
            --log-file=$SNAP_COMMON/logs/nova-manage.log

entry points are designed to be executed from the snapcraft.yaml apps section using:

command: snap-openstack nova-manage

any additional arguments provided will be passed to the underlying binary.
