providers/outscale: add Outscale support - #2296
Conversation
📝 WalkthroughWalkthroughAdds an Outscale provider that reads Ignition configuration from the instance user-data endpoint. Registers the provider, documents Outscale as supported, and adds the feature to the Ignition 2.28.0 release notes. ChangesOutscale provider support
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟡 Moderate · up to Outscale instances with an empty user-data response can fail to obtain configuration instead of continuing with an empty configuration. The PR should be updated to handle zero-length successful responses before merge. Sequence Diagram(s)sequenceDiagram

Handle missing user-data as an empty configuration
util.ParseConfig returns errors.ErrEmpty for zero-length data. Return an empty configuration when user-data is absent or empty.

Handle empty successful user-data responses as no configuration.
resource.ErrNotFound handling covers a missing endpoint response, but it does not cover an empty successful response. FetchToBuffer accepts HTTP 204 and can return zero-length data; util.ParseConfig then returns errors.ErrEmpty. An Outscale instance without populated user-data can therefore fail instead of continuing with an empty configuration. (raw.githubusercontent.com)
Return an empty types.Config when len(data) == 0, while preserving non-resource.ErrNotFound errors and parsing non-empty data.
As per path instructions, “Platform providers must retry config fetches, allow empty config, and never guess the platform ID.”
Proposed fix
if err != nil {
if err == resource.ErrNotFound {
return types.Config{}, report.Report{}, nil
}
return types.Config{}, report.Report{}, err
}
+ if len(data) == 0 {
+ return types.Config{}, report.Report{}, nil
+ }

Add support for the Outscale cloud platform.
Outscale provides an AWS-compatible metadata service at
http://169.254.169.254/latest/ with no IMDSv2 requirement.
The provider fetches the Ignition config from the instance
user-data endpoint.
The provider follows the same pattern as other simple
providers (Hetzner, Vultr, Exoscale).
Tested on an Outscale VM — the metadata service responds
correctly to both /latest/meta-data/ and /latest/user-data
endpoints.
