-- 2. ECSインスタンスの作成

aliyun ecs DescribeInstances 

aliyun ecs DescribeInstances \
| jq ".Instances.Instance | [.InstanceId, .InstanceName, .Status]"

aliyun ecs CreateInstance \
--InstanceType ecs.e-c4m1.large \
--CreditSpecification Standard \
--DeletionProtection false \
--Description instance01 \
--HostName instance01 \
--ImageId aliyun_2_1903_x64_20G_alibase_20231221.vhd \
--InstanceChargeType PostPaid \
--InstanceName instance01 \
--KeyPairName alibabakey01 \
--SecurityGroupId sg-11111111111111111111 \
--SystemDisk.Category cloud_essd \
--SystemDisk.Size 20 \
--VSwitchId vsw-111111111111111111111 \
--ZoneId ap-northeast-1a 

ECSインスタンスの起動
aliyun ecs StartInstance \
--InstanceId i-11111111111111111111 

ECSインスタンスの削除
aliyun ecs DeleteInstance \
--InstanceId i-11111111111111111111 \
--Force true 

-- 3. EIP割り当て

aliyun vpc DescribeEipAddresses 

aliyun vpc AssociateEipAddress \
--AllocationId eip-111111111111111111111 \
--InstanceId i-11111111111111111111 \
--InstanceType EcsInstance

EIP割り当て解除
aliyun vpc UnassociateEipAddress \
--AllocationId eip-111111111111111111111 \
--InstanceId i-11111111111111111111 \
--InstanceType EcsInstance 

-- 4. インスタンスタイプの変更

aliyun ecs DescribeInstanceTypeFamilies 

aliyun ecs DescribeInstanceTypes 

aliyun ecs DescribeInstanceTypes \
| jq -c '.InstanceTypes.InstanceType | [ .InstanceTypeId, .CpuCoreCount, .MemorySize, .CpuArchitecture ]' 

aliyun ecs DescribeInstances \
| jq ".Instances.Instance[] | [.InstanceId, .InstanceName, .Status]"

※事前にインスタンス停止とEIP割り当て解除必要

EIP割り当て解除
aliyun vpc UnassociateEipAddress \
--AllocationId eip-111111111111111111111 \
--InstanceId i-11111111111111111111 \
--InstanceType EcsInstance 

ECSインスタンスの停止
aliyun ecs StopInstance \
--InstanceId i-11111111111111111111 \
--StoppedMode StopCharging 

aliyun ecs ModifyInstanceSpec \
--InstanceId i-11111111111111111111 \
--InstanceType ecs.e-c2m1.large 

ECSインスタンスの起動
aliyun ecs StartInstance \
--InstanceId i-11111111111111111111 

EIP割り当て
aliyun vpc AssociateEipAddress \
--AllocationId eip-111111111111111111111 \
--InstanceId i-11111111111111111111 \
--InstanceType EcsInstance
