Edge APIs

This repository contains the Open API 2.0 specification for the OpenZiti Edge Client and Management REST APIs. It also contains a generated go module, in the rest_* directories that can be used to develop against OpenZiti Controllers.

Versioning

Versioning of the APIs in this repository is independent of the OpenZiti releases created in the ziti repository. Many versions of these API specifications are compatible with multiple versions of the OpenZiti release versions. To make it somewhat intuitive, the minor version number of the API is the minimum minor version of the ziti repository releases that this API is compatible with. It will also be compatible up until the next minor version of the specifications. Patch versions are used for internal fixes and release tags.

For simplicity, each controller hosts the specification version they expect and may be used instead of this repository for live deployments.

Client & Server Generation

The root-level client.yml and management.yml OpenAPI 2.0 specification files are generated from the source directory. There are scripts in ./scripts/ for re-generating these specifications and the Go client and server libraries. The scripts require that a specific build of the swagger (aka "go-swagger") executable. Download the Go-Swagger v0.29.0 binary from GitHub.

Do not go install the binary because the rendering may introduce whitespace changes in many files.

Modify the Specification Sources

These files are used to build the specifications.

./source
├── client
├── client.yml
├── management
├── management.yml
└── shared

Bump the Specification Version

Update the version numbers in ./source/client.yml and ./source/management.yml in your PR. The versions must be identical.

Prepare the Local Filesystem

You must clone two repos in adjacent directories.

  1. this repo - https://github.com/openziti/edge-api.git
  2. the main ziti repo - https://github.com/openziti/ziti.git

Generate the Specifications and Test

You must create a workspace for the main repo (ziti) to run tests against the checkout in this repo (edge-api).

Linux/Darwin Example

(
    set -euxo pipefail;
    ./scripts/generate_rest.sh;
    (
        cd ../ziti;
        [[ -s ./go.work ]] && mv -v ./go.work{,.$(date --utc --iso-8601=seconds)};
        go work init;
        go work use .;
        go work use ../edge-api;
        go test ./... -tags apitests;
    )
)

Windows Example

#powershell
./scripts/generate_rest.ps1

Using the generated go module

Within the go module within the go directory is a submodule named rest_util containing helper functions for using its sibling *_client submodules. This package is not generated. See rest_util/examples for full examples.

Example:

func main() {
	ctrlAddress := "https://localhost:1280"
	caCerts, err := rest_util.GetControllerWellKnownCas(ctrlAddress)

	if err != nil {
		log.Fatal(err)
	}

	caPool := x509.NewCertPool()

	for _, ca := range caCerts {
		caPool.AddCert(ca)
	}

	ok, err := rest_util.VerifyController(ctrlAddress, caPool)

	if err != nil {
		log.Fatal(err)
	}

	if !ok {
		log.Fatal("controller failed CA validation")
	}

	client, err := rest_util.NewEdgeManagementClientWithUpdb("admin", "admin", ctrlAddress, caPool)

	if err != nil {
		log.Fatal(err)
	}

	params := &identity.ListIdentitiesParams{
		Context: context.Background(),
	}

	resp, err := client.Identity.ListIdentities(params, nil)

	if err != nil {
		log.Fatal(err)
	}

	println("\n=== Identity List ===")
	for _, identityItem := range resp.GetPayload().Data {
		println(*identityItem.Name)
	}
}
