This is the implementation of a CAPIF Invoker

• This repo is intended to be used as a test method for CAPIF services and services published on CAPIF.

Before executing the following code it is necessary to have raised an instance of CAPIF.

This repo is designed to be executed from docker, to create the images and raise the instance it is only necessary to execute the following command:

./run.sh

• Before executing the run.sh command, note that it supports one parameter, this parameter is the CAPIF hostname, by default this field is 'capifcore'. Modify it if necessary or add the hostname when executing the run.sh command

  ./run.sh <other_hostname>
  
  

• It is important to have the following environment variables in the docker-compose file:

  - REGISTER_HOSTNAME = register
  - EASY_RSA_HOSTNAME = easy-rsa
  - CAPIF_PORT=8080
  - EASY_RSA_PORT=8083
  - REGISTER_PORT=8084
  
  extra_hosts:
    - host.docker.internal:host-gateway
    - capifcore:host-gateway
    - register:host-gateway
    - easy-rsa:host-gateway
  
  

  These environment variables refer to the certificate signing and registration services. By default, these are the ports and names that the CAPIF script uses when launching the different services. If during the deployment of CAPIF you modify these parameters, you must modify them so that they correspond to the new ones.

  If the hostname environment variables are modified, the extra host must also be modified so that the hostnames correspond and be able to reach the services deployed in docker.

Now it is only necessary to enter inside the container by executing this command

./terminal_to_py_aef.sh

Once inside the container you can run the provider command GUI by running

./python main.py

The provider is prepared to make the necessary previous provisions automatically. The different .json files that must be saved in CAPIF are also added. To make the necessary provisions you just have to execute the following commands within the GUI

register_invoker

discover_service

register_security_context

get_security_auth

• The previous commands are to register an invoker within CAPIF, discover the services that have been published and if there are any published services, create a security context to use those services.

*If the first command returns a 401, it means that the token to interact the first time with CAPIF has expired, run the following command

get_auth

call_service

If the previous process has been executed correctly, the call_service command will call the first endpoint of the service that has been discovered.

If you want to call another endpoint or modify the parameters that are sent to the service, you must modify the code directly
