Aumento das especificações da instância

Função

Essa API é usada para modificar as especificações da instância. Atualmente, essa API só pode ser usada para aumentar as especificações de instâncias de pagamento por uso.

Método de chamada

Para obter detalhes, consulte Chamada de APIs.

URI

POST /v2/{engine}/{project_id}/instances/{instance_id}/extend

Tabela 1 Parâmetros de caminho

Parâmetro

Obrigatório

Tipo

Descrição

engine

Sim

String

Mecanismo de mensagens.

Padrão: kafka

project_id

Sim

String

ID do projeto. Para obter detalhes sobre como obtê-lo, consulte Obtenção de um ID de projeto.

instance_id

Sim

String

ID da instância.

Parâmetros de solicitação

Tabela 2 Parâmetros do corpo da solicitação

Parâmetro

Obrigatório

Tipo

Descrição

oper_type

Sim

String

Tipo de mudança.

Intervalo de valores:

  • storage: expandir o armazenamento sem alterar a quantidade do corretor.
  • horizontal: adicionar corretores sem redimensionar o espaço de armazenamento de cada corretor.
  • vertical: ampliar o flavor do corretor sem alterar a quantidade e o armazenamento do corretor.

new_storage_space

Não

Integer

Novo espaço de armazenamento.

Este parâmetro é válido e obrigatório quando oper_type é definido como storage ou horizontal.

Espaço de armazenamento da instância = Número de corretores x Espaço de armazenamento de cada corretor.

Se oper_type estiver definido como storage, o número de corretores permanece inalterado e o espaço de armazenamento de cada corretor deve ser expandido em pelo menos 100 GB.

  • Se oper_type for definido como horizontal, o espaço de armazenamento de cada corretor permanecerá inalterado.

new_broker_num

Não

Integer

Este parâmetro é válido somente quando oper_type é definido como horizontal.

Intervalo de valores: um máximo de 30 corretores são suportados.

new_product_id

Não

String

Novo ID de produto para aumento de escala.

Este parâmetro é válido e obrigatório quando oper_type é definido como vertical.

Obtenha o ID do produto a partir da Consulta à lista de especificações do produto.

publicip_id

Não

String

ID do EIP vinculado à instância.

Use vírgulas (,) para separar vários IDs de EIP.

Este parâmetro é obrigatório quando oper_type é definido como horizontal.

tenant_ips

Não

Array of strings

Endereços IP privados IPv4 especificados.

O número de endereços IP especificados deve ser menor ou igual ao número de novos corretores.

Se o número de endereços IP especificados for menor que o número de corretores, os corretores não especificados receberão endereços IP privados aleatoriamente atribuídos.

second_tenant_subnet_id

Não

String

ID da sub-rede em espera usada pelos novos corretores na expansão da instância.

Esse valor é transferido quando uma sub-rede em espera é usada na expansão da instância.

Entre em contato com o atendimento ao cliente para usar o valor.

Parâmetros de resposta

Código de status: 200

Tabela 3 Parâmetros do corpo de resposta

Parâmetro

Tipo

Descrição

job_id

String

ID da tarefa de modificação da especificação.
