Migrating from legacy service extensions

Legacy service extensions imported a lot of the functionality via globals defined at the package level. The new configuration sources all inputs from the orchestrator.Orchestrator interface.

The following code snippets are meant only as examples to demonstrate the changes and updates between the legacy and new service extension interfaces.

Logging
Secret Provider
Identity Provider
Attribute Provider
Session
Registering Routes

Logging

// import "github.com/strata-io/service-extension/orchestrator"
// api orchestrator.Orchestrator
logger := api.Logger()
logger.Info("se", "this is an info log")
logger.Error("se", "this is an error log")
logger.Debug("se", "this is a debug log")

// import "maverics/log"
log.Info("se", "this is an info log")
log.Error("se", "this is an error log")
log.Debug("se", "this is a debug log")

Secret Provider

// import "github.com/strata-io/service-extension/orchestrator"
// api orchestrator.Orchestrator
secret := api.SecretProvider()
secret.GetString("app1OIDCClientSecret")

// import "maverics/secret"
secret.GetString("app1OIDCClientSecret")

Identity Provider

// import "github.com/strata-io/service-extension/orchestrator"
// api orchestrator.Orchestrator
azure, err := api.IdentityProvider("azure")
azure.Login(rw, req)

// import "maverics/app"
// ag *app.AppGateway
azure, ok := ag.IDPs["azure"]
azure.CreateRequest().Login(rw, req)

Attribute Provider

// import "github.com/strata-io/service-extension/orchestrator"
// api orchestrator.Orchestrator
ldap, err := api.AttributeProvider("ldap")
attrs, err := ldap.Query(mail, []string{"cn", "sn", "mobile"})

// import "maverics/app"
// ag *app.AppGateway
ldap, ok := ag.AttrProviders["ldap"]
attrs, err := ldap.Query(mail, []string{"cn", "sn", "mobile"})

Session

    // import "github.com/strata-io/service-extension/orchestrator"
    // api orchestrator.Orchestrator
	session, err := api.Session()
	isAzureAuth, err := session.GetString("azure.authenticated")

	// Now saving information to the session is a two-step process.
    err = session.SetString(k, v)
	err = session.Save()

	
	// import "maverics/session"
	isAuth := session.GetString(req, "authenticated")
	session.SetString(req, "authenticated", "true")

Registering Routes

    // import "github.com/strata-io/service-extension/orchestrator"
    // api orchestrator.Orchestrator
	router := api.Router()
	router.HandleFunc("/error", func(rw http.ResponseWriter, req *http.Request){})

	// import "net/http"
	http.HandleFunc("/error", func(rw http.ResponseWriter, req *http.Request){})
