If RAX_CREDS_FILE is 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. See

RAX_REGION is an optional environment variable to narrow inventory search
scope. RAX_REGION, if used, needs a value like ORD, DFW, SYD (a Rackspace
datacenter) and optionally accepts a comma-separated list.
RAX_ENV is an environment variable that will use an environment as
configured in ~/.pyrax.cfg, see
https://github.com/rackspace/pyrax/blob/master/docs/getting_started.md#pyrax-configuration
- RAX_META_PREFIX is an environment variable that changes the prefix used
https://github.com/rackspace/pyrax/blob/master/docs/getting_started.md
RAX_META_PREFIX is an environment variable that changes the prefix used
for meta key/value groups. For compatibility with ec2.py set to
RAX_META_PREFIX=tag
requirements: [ "pyrax" ]
examples:
- description: List server instances
code: RAX_CREDS_FILE=~/.raxpub rax.py --list
- description: List servers in ORD datacenter only
code: RAX_CREDS_FILE=~/.raxpub RAX_REGION=ORD rax.py --list
- description: List servers in ORD and DFW datacenters
code: RAX_CREDS_FILE=~/.raxpub RAX_REGION=ORD,DFW rax.py --list
- description: Get server details for server named "server.example.com"
code: RAX_CREDS_FILE=~/.raxpub rax.py --host server.example.com
'''
RAX_ACCESS_NETWORK is an environment variable 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.
RAX_ACCESS_IP_VERSION is an environment variable related to
RAX_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.
Examples:
List server instances
$ RAX_CREDS_FILE=~/.raxpub rax.py --list
List servers in ORD datacenter only
$ RAX_CREDS_FILE=~/.raxpub RAX_REGION=ORD rax.py --list
List servers in ORD and DFW datacenters
$ RAX_CREDS_FILE=~/.raxpub RAX_REGION=ORD,DFW rax.py --list
Get server details for server named "server.example.com"
$ RAX_CREDS_FILE=~/.raxpub rax.py --host server.example.com
Use the instance private IP to connect (instead of public IP)
$ RAX_CREDS_FILE=~/.raxpub RAX_PRIVATE_IP=yes rax.py --list
