rax.py inventory: improvements

plugins/inventory/rax.ini

+# Ansible Rackspace external inventory script settings
+#
+
+[rax]
+
+# Environment Variable: RAX_CREDS_FILE
+#
+# An optional configuration that points to a pyrax-compatible credentials
+# file.
+#
+# If not supplied, rax.py will look for a credentials file
+# at ~/.rackspace_cloud_credentials.  It uses the Rackspace Python SDK,
+# and therefore requires a file formatted per the SDK's specifications.
+#
+# https://github.com/rackspace/pyrax/blob/master/docs/getting_started.md
+# creds_file = ~/.rackspace_cloud_credentials
+
+# Environment Variable: RAX_REGION
+#
+# An optional environment variable to narrow inventory search
+# scope. If used, needs a value like ORD, DFW, SYD (a Rackspace
+# datacenter) and optionally accepts a comma-separated list.
+# regions = IAD,ORD,DFW
+
+# Environment Variable: RAX_ENV
+#
+# A configuration that will use an environment as configured in
+# ~/.pyrax.cfg, see
+# https://github.com/rackspace/pyrax/blob/master/docs/getting_started.md
+# env = prod
+
+# Environment Variable: RAX_META_PREFIX
+# Default: meta
+#
+# A configuration that changes the prefix used for meta key/value groups.
+# For compatibility with ec2.py set to "tag"
+# meta_prefix = meta
+
+# Environment Variable: RAX_ACCESS_NETWORK
+# Default: public
+#
+# A configuration that will tell the inventory script to use a specific
+# server network to determine the ansible_ssh_host value. If no address
+# is found, ansible_ssh_host will not be set. Accepts a comma-separated
+# list of network names, the first found wins.
+# access_network = public
+
+# Environment Variable: RAX_ACCESS_IP_VERSION
+# Default: 4
+#
+# A configuration related to "access_network" that will attempt to
+# determine the ansible_ssh_host value for either IPv4 or IPv6. If no
+# address is found, ansible_ssh_host will not be set.
+# Acceptable values are: 4 or 6. Values other than 4 or 6
+# will be ignored, and 4 will be used. Accepts a comma separated list,
+# the first found wins.
+# access_ip_version = 4
