Go TMF Service application

• Application is in developing stage

Application contains:

TMF 641 v4.2 - Service Ordering Management

• Version 4.2.0 The Service Order API provides a standardized mechanism for managing Service Order, a type of order which can be used to place an order between internal Customer Order management system to service order management system or between a service provider and a partner and vice versa.

Service Order resource

• A service order will describe a list of service order items. A service order item references an action on an existing or future service. By service we designed Customer Facing Service (CFS) as well as Resource Facing Service (RFS). From a component perspective, a service order should be available
• from a Service Orchestration Component (and it could mix CFS and RFS)
• from an Infrastructure Control & Management component (and it would have only RFS)

TMF641 performs the following operations on service order resource :

• Retrieval of a service order or a collection of service orders depending on filter criteria
• Partial update of a service order (including updating rules)
• Creation of a service order (including default values and creation rules)
• Deletion of service order (for administration purposes)
• Notification of events on Service order The REST API for Service Order Management provides a standardized mechanism for placing a service order with all the necessary order parameters. It allows users to create, update & retrieve Service Orders and manages related notifications.

Install Go Swagger

sudo apt install -y apt-transport-https gnupg curl debian-keyring debian-archive-keyring

• Register GPG signing key

curl -1sLf 'https://dl.cloudsmith.io/public/go-swagger/go-swagger/gpg.2F8CB673971B5C9E.key' | sudo gpg --dearmor -o /usr/share/keyrings/go-swagger-go-swagger-archive-keyring.gpg
curl -1sLf 'https://dl.cloudsmith.io/public/go-swagger/go-swagger/config.deb.txt?distro=debian&codename=any-version' | sudo tee /etc/apt/sources.list.d/go-swagger-go-swagger.list

• Install

sudo apt update 
sudo apt install swagger

Validate Swagger specification

$ task swagger.validate.v4

Generate Swagger documentation

$ task swagger.doc.v4

Generate a self-signed TLS for local development

• Install OpenSSL

sudo apt install openssl

• Generate a Private Key

• • A private key is a cryptographic key used to encrypt and decrypt data. It's essential for establishing secure communication in TLS/SSL.

openssl genrsa -out tls.key 2048

• Create a Certificate Signing Request (CSR)
• • A CSR is a file that contains your public key and organization details. It’s used when requesting a certificate from a Certificate Authority (CA). For a self-signed certificate, it’s still a necessary step as it includes key metadata and helps create the certificate.

openssl req -new -key tls.key -out tls.csr

• Generate a Self-Signed Certificate
• • A self-signed certificate is a certificate you sign yourself (instead of relying on a CA). It’s suitable for local development or testing but not recommended for production.

openssl x509 -req -in tls.csr -signkey tls.key -out tls.crt -days 365

Run server

go run main.go --tls-certificate=tls.crt --tls-key=tls.key  --tls-port=34191
