module: rax_files
short_description: Manipulate Rackspace Cloud Files Containers
description:
- Manipulate Rackspace Cloud Files Containers
version_added: "1.5"
options:
api_key:
description:
- Rackspace API key (overrides I(credentials))
clear_meta:
description:
- Optionally clear existing metadata when applying metadata to existing containers.
Selecting this option is only appropriate when setting type=meta
choices: ["yes", "no"]
default: "no"
container:
description:
- The container to use for container or metadata operations.
required: true
credentials:
description:
- File to find the Rackspace credentials in (ignored if I(api_key) and
I(username) are provided)
default: null
aliases: ['creds_file']
meta:
description:
- A hash of items to set as metadata values on a container
private:
description:
- Used to set a container as private, removing it from the CDN. B(Warning!)
Private containers, if previously made public, can have live objects
available until the TTL on cached objects expires
public:
description:
- Used to set a container as public, available via the Cloud Files CDN
region:
description:
- Region to create an instance in
default: DFW
state:
description:
- Indicate desired state of the resource
choices: ['present', 'absent']
default: present
ttl:
description:
- In seconds, set a container-wide TTL for all objects cached on CDN edge nodes.
Setting a TTL is only appropriate for containers that are public
type:
description:
- Type of object to do work on, i.e. metadata object or a container object
choices: ["file", "meta"]
default: "file"
username:
description:
- Rackspace username (overrides I(credentials))
web_error:
description:
- Sets an object to be presented as the HTTP error page when accessed by the CDN URL
web_index:
description:
- Sets an object to be presented as the HTTP index page when accessed by the CDN URL
requirements: [ "pyrax" ]
author: Paul Durivage
notes:
- The following environment variables can be used, C(RAX_USERNAME),
C(RAX_API_KEY), C(RAX_CREDS_FILE), C(RAX_CREDENTIALS), C(RAX_REGION).
- C(RAX_CREDENTIALS) and C(RAX_CREDS_FILE) points to a credentials file
appropriate for pyrax. See U(https://github.com/rackspace/pyrax/blob/master/docs/getting_started.md#authenticating)
- C(RAX_USERNAME) and C(RAX_API_KEY) obviate the use of a credentials file
- C(RAX_REGION) defines a Rackspace Public Cloud region (DFW, ORD, LON, ...)
