Añadir miembros
Excelente, ahora tenemos el esquema necesario para crear el sujeto tipo Wine. Sin embargo, reflexionando, nos damos cuenta de que no hay nadie autorizado para crear y emitir eventos relacionados con este nuevo esquema. Por lo tanto, necesitamos agregar un nuevo participante a nuestra red responsable de esta tarea.
Comencemos configurando el nodo correspondiente:
{
"kore": {
"network": {
"listen_addresses": ["/ip4/0.0.0.0/tcp/50000"],
"routing": {
"boot_nodes": ["/ip4/172.17.0.1/tcp/50000/p2p/{{PEER-ID}}"]
}
}
}
}
Mapeamos el puerto 3001 para realizar peticiones desde nuestra máquina e indicamos el peer-id
del nodo 1.
docker run -p 3001:3000 -p 50001:50000 -e KORE_PASSWORD=polopo -e KORE_FILE_PATH=./config.json -v ./config2.json:/config.json koreadmin/kore-http:0.5-leveldb-prometheus
A continuación, procederemos a actualizar la gobernanza para incluir a este nuevo miembro y permitirle crear asuntos tipo Wine.
No es necesario asignarles el rol de testigo, ya que el propietario del sujeto es el testigo predeterminado. INFO
Verifiquemos los cambios que queremos realizar en las propiedades de gobierno. En este punto, nuestra gobernanza debería verse así:
{
"members": [
{
"id": "{{CONTROLLER-ID}}",
"name": "WPO"
}
],
"roles": [
{
"namespace": "",
"role": "WITNESS",
"schema": {
"ID": "governance"
},
"who": "MEMBERS"
},
{
"namespace": "",
"role": "APPROVER",
"schema": {
"ID": "governance"
},
"who": {
"NAME": "WPO"
}
}
]
}
Ahora, necesitamos incorporar los cambios mencionados:
{
"members": [
...
{
"id": "{{CONTROLLER-ID}}",
"name": "PremiumWines"
}
],
"roles": [
...
{
"namespace": "",
"role": "CREATOR",
"schema": {
"ID": "Wine"
},
"who": {
"NAME": "PremiumWines"
}
}
]
}
Usaremos nuestra herramienta Kore-Patch para generar estos cambios, siguiendo el procedimiento a continuación:
kore-patch '{"members":[{"id":"{{CONTROLLER-ID}}","name":"WPO"}],"roles":[{"namespace":"","role":"WITNESS","schema":{"ID":"governance"},"who":"MEMBERS"},{"namespace":"","role":"APPROVER","schema":{"ID":"governance"},"who":{"NAME":"WPO"}}]}' '{"members":[{"id":"{{CONTROLLER-ID}}","name":"WPO"},{"id":"{{CONTROLLER-ID}}","name":"PremiumWines"}],"roles":[{"namespace":"","role":"WITNESS","schema":{"ID":"governance"},"who":"MEMBERS"},{"namespace":"","role":"APPROVER","schema":{"ID":"governance"},"who":{"NAME":"WPO"}},{"namespace":"","role":"CREATOR","schema":{"ID":"Wine"},"who":{"NAME":"PremiumWines"}}]}'
El resultado obtenido será el siguiente:
[
{
"op": "add",
"path": "/members/1",
"value": {
"id": "{{CONTROLLER-ID}}",
"name": "PremiumWines"
}
},
{
"op": "add",
"path": "/roles/2",
"value": {
"namespace": "",
"role": "CREATOR",
"schema": {
"ID": "Wine"
},
"who": {
"NAME": "PremiumWines"
}
}
}
]
Ahora es el momento de llamar al método del contrato de la gobernanza responsable de actualizar sus propiedades. Para hacer esto, ejecutaremos lo siguiente:
Evento
Pincha para ver el evento
curl --request POST 'http://localhost:3000/event-requests' \
--header 'Content-Type: application/json' \
--data-raw '{
"request": {
"Fact": {
"subject_id": "{{GOVERNANCE-ID}}",
"payload": {
"Patch": {
"data": [{
"op": "add",
"path": "/members/1",
"value": {
"id": "{{CONTROLLER-ID}}",
"name": "PremiumWines"
}
},
{
"op": "add",
"path": "/roles/2",
"value": {
"namespace": "",
"role": "CREATOR",
"schema": {
"ID": "Wine"
},
"who": {
"NAME": "PremiumWines"
}
}
}]
}
}
}
}
}'
Una vez emitido el evento, necesitamos obtener la nueva solicitud de actualización. Para ello ejecutamos lo siguiente:
curl --request GET 'http://localhost:3000/approval-requests?status=Pending'
Copiamos el valor del campo id
y aceptamos la solicitud de actualización de gobernanza:
curl --request PATCH 'http://localhost:3000/approval-requests/{{PREVIUS-ID}}' \
--header 'Content-Type: application/json' \
--data-raw '{"state": "RespondedAccepted"}'
Consultamos la gobernanza desde el nuevo nodo(puerto 3001):
curl --request GET 'http://localhost:3001/subjects/{{GOVERNANCE-ID}}'
Obtendremos lo siguiente:
[]
¿Un error? ¿Pero no acabamos de incluir el nuevo nodo en la gobernanza y es testigo de ello?
Si bien lo último es cierto, debemos considerar lo siguiente: por razones de seguridad, el nodo kore rechaza todos los sujetos que no hayan sido enviados explícitamente, a menos que se cumpla una de las dos condiciones siguientes: la gobernanza está configurada para considerarlo un testigo, o autorizamos explícitamente al sujeto. En el caso de la gobernanza, es especial ya que no existe una gobernanza previa que la autorice, por lo que la única forma de acceder es autorizándola explícitamente.
Por lo tanto, debemos ejecutar lo siguiente para recibir información de gobernanza:
curl --request PUT 'http://localhost:3001/allowed-subjects/{{GOVERNANCE-ID}}' \
--header 'Content-Type: application/json' \
--data-raw '{
"providers": []
}'
Ahora, al intentar consultar la gobernanza desde el nuevo nodo, obtendremos la información esperada:
curl --request GET 'http://localhost:3001/subjects/{{GOVERNANCE-ID}}'

Organización Mundial de la Alimentación
Actualmente, WPO es el único propietario de la gobernanza y tiene el poder exclusivo de aprobar cambios en la misma. Sin embargo, esto plantea un problema ya que su poder es absoluto y, por ejemplo, carece de representación o influencia de todo el mundo en los cambios realizados en esta gobernanza. Por lo tanto, es necesario agregar un nuevo miembro a la gobernanza, la Organización Mundial de la Alimentación (WFO), que actuará como segundo validador y evitará el monopolio existente de WPO.
Para lograr esto, permitiremos que WFO asuma las funciones de aprobador, validador y evaluador de la gobernanza. Además, se le permitirá actuar como testigo en el sujeto de tipo Vino ya que le interesa recopilar estadísticas de consumo.
Comencemos configurando el nodo WFO:
docker run -p 3002:3000 -p 50002:50000 -e KORE_PASSWORD=polopo -e KORE_FILE_PATH=./config.json -v ./config2.json:/config.json koreadmin/kore-http:0.5-leveldb-prometheus
A continuación procederemos a actualizar la gobernanza para otorgarle las propiedades mencionadas:

En este punto, los pasos para generar el nuevo Json Patch para la gobernanza no se describen ya que están detallados en la sección anterior. CAUTION
Una vez ejecutado este comando, deberíamos obtener nuevamente la solicitud de actualización. Para ello ejecutamos:
curl --request GET 'http://localhost:3000/approval-requests?status=Pending'
Copiamos el valor del campo id
y aceptamos la solicitud de actualización de gobernanza:
curl --request PATCH 'http://localhost:3000/approval-requests/{{PREVIUS-ID}}' \
--header 'Content-Type: application/json' \
--data-raw '{"state": "RespondedAccepted"}'
Llegados a este punto, nos encontraremos en una situación similar a la descrita en el sección anterior. Aunque el nuevo nodo es parte de la gobernanza, no puede recibir su información, por lo que necesitamos realizar su preautorización. Para hacer esto, ejecutaremos el siguiente comando:
curl --request PUT 'http://localhost:3002/allowed-subjects/{{GOVERNANCE-ID}}' \
--header 'Content-Type: application/json' \
--data-raw '{
"providers": []
}'
Si todo ha ido como se esperaba, ahora podemos consultar la gobernanza del nuevo nodo, y ahora debería tener un valor sn
de 4, así como el cambio realizado en miembros y roles.
curl --request GET 'http://localhost:3002/subjects/{{GOVERNANCE-ID}}'
