We need an API for Warewulf in order to automate around it. The initial version of the API will look a lot like wwctl. wwctl will call the API so that we do not need to maintain separate code paths. In this preview wwctl calls the API via direct function call, but we can change that to a gprc or REST call to a Warewulf server in the future.
This commit contains:
wwapid WareWulf API Daemon. A grpc server with mTLS auth.
wwapic WareWulf API Client. A grpc client with mTLS auth. It's just a sample that reads the version from the server.
wwapird WareWulf API Rest Daemon. A http REST reverse proxy to wwapid.
There are also sample insecure and secure curls to test with.
Implemented Functionality:
wwctl node add
wwctl node delete
wwctl node list
wwctl node set
wwctl node status
wwctl container build
wwctl container delete
wwctl container import
wwctl container list
wwctl container show
Some notes on the files:
Logic that was in wwctl has moved to warewulf/internal/pkg/api. wwctl just calls the API. wwctl functionality is unchanged.
Everything under the /google directory is copied google proto code to stand up wwapird. It's a bit strange to copy in the code, but that is currently how it's done.
Everything in warewulf/internal/pkg/api/routes/wwapiv1 is generated code.
There are some loose ends here, such as no service installers. I just ran off the command line for development.
The Makefile could use improvement. I'm building by make clean setup proto all build wwapid wwapic wwapird ; echo $?
I copied the configs from warewulf/etc to /usr/local/etc/warewulf manually.

// The `Status` type defines a logical error model that is suitable for different
|
|
// programming environments, including REST APIs and RPC APIs. It is used by
|
|
// [gRPC](https://github.com/grpc). The error model is designed to be:
|
|
//
|
|
// - Simple to use and understand for most users
|
|
// - Flexible enough to meet unexpected needs
|
|
//
|
|
// # Overview
|
|
//
|
|
// The `Status` message contains three pieces of data: error code, error message,
|
|
// and error details. The error code should be an enum value of
|
|
// [google.rpc.Code][google.rpc.Code], but it may accept additional error codes if needed. The
|
|
// error message should be a developer-facing English message that helps
|
|
// developers *understand* and *resolve* the error. If a localized user-facing
|
|
// error message is needed, put the localized message in the error details or
|
|
// localize it in the client. The optional error details may contain arbitrary
|
|
// information about the error. There is a predefined set of error detail types
|
|
// in the package `google.rpc` that can be used for common error conditions.
|
|
//
|
|
// # Language mapping
|
|
//
|
|
// The `Status` message is the logical representation of the error model, but it
|
|
// is not necessarily the actual wire format. When the `Status` message is
|
|
// exposed in different client libraries and different wire protocols, it can be
|
|
// mapped differently. For example, it will likely be mapped to some exceptions
|
|
// in Java, but more likely mapped to some error codes in C.
|
|
//
|
|
// # Other uses
|
|
//
|
|
// The error model and the `Status` message can be used in a variety of
|
|
// environments, either with or without APIs, to provide a
|
|
// consistent developer experience across different environments.
|
|
//
|
|
// Example uses of this error model include:
|
|
//
|
|
// - Partial errors. If a service needs to return partial errors to the client,
|
|
// it may embed the `Status` in the normal response to indicate the partial
|
|
// errors.
|
|
//
|
|
// - Workflow errors. A typical workflow has multiple steps. Each step may
|
|
// have a `Status` message for error reporting.
|
|
//
|
|
// - Batch operations. If a client uses batch request and batch response, the
|
|
// `Status` message should be used directly inside batch response, one for
|
|
// each error sub-response.
|
|
//
|
|
// - Asynchronous operations. If an API call embeds asynchronous operation
|
|
// results in its response, the status of those operations should be
|
|
// represented directly using the `Status` message.
|
|
//
|
|
// - Logging. If some API errors are stored in logs, the message `Status` could
|
|
// be used directly after any stripping needed for security/privacy reasons.
|
|
message Status {
|
|
// The status code, which should be an enum value of [google.rpc.Code][google.rpc.Code].
|
|
int32 code = 1;
|
|
|
|
// A developer-facing error message, which should be in English. Any
|
|
// user-facing error message should be localized and sent in the
|
|
// [google.rpc.Status.details][google.rpc.Status.details] field, or localized by the client.
|
|
string message = 2;
|
|
|
|
// A list of messages that carry the error details. There is a common set of
|
|
// message types for APIs to use.
