configdrive: Use the EC2 metadata over OpenStack Standardize on specific EC2 and OpenStack versions and add tests. 2014-07-20 07:18:25 +04:00			`const (`

refactor(*): Break apart packages 2014-03-18 20:00:41 +04:00			`type Datasource interface {`
datasources: Add support for specifying multiple datasources If multiple sources are specified, the first available source is used. 2014-06-27 02:17:53 +04:00			`IsAvailable() bool`
			`AvailabilityChanges() bool`
refactor(env): Add the config root and netconf type to datasource and env 2014-06-18 22:36:06 +04:00			`ConfigRoot() string`
feat(metadata): Distinguish between userdata and metadata for datasources 2014-06-18 22:58:18 +04:00			`FetchMetadata() ([]byte, error)`
			`FetchUserdata() ([]byte, error)`
Use exponential backoff when fetching user-data from an URL. The user-cloudinit-proc-cmdline systemd unit is responsible for fetching user-data from various sources during the cloud-init process. When fetching user-data from an URL datasource we face a race condition since the network may not be available, which can cause the job to fail and no further attempts to fetch the user-data are made. Eliminate the race condition when fetching user-data from an URL datasource. Retry the fetch using an exponential backoff until the user-data is retrieved. Fixes issue 105. 2014-05-15 09:20:40 +04:00			`Type() string`
