需要根据另一个值

Question

我正在尝试使用EC2现货船队请求。我需要根据ImageId的传入值提取SpotFleetRequestId。我无法弄清楚。有人可以帮忙吗？这是json：

{

“SpotFleetRequestConfigs”：[       {           “SpotFleetRequestId”：“sfr-73fbd2ce-aa30-494c-8788-1cee4EXAMPLE”，           “SpotFleetRequestConfig”：{               “TargetCapacity”：20，               “LaunchSpecifications”：[                   {                       “EbsOptimized”：false，                       “NetworkInterfaces”：[                           {                               “SubnetId”：“subnet-a61dafcf”，                               “DeviceIndex”：0，                               “DeleteOnTermination”：false，                               “AssociatePublicIpAddress”：是的，                               “SecondaryPrivateIpAddressCount”：0                           }                       ]                       “InstanceType”：“cc2.8xlarge”，                       “ImageId”：“ami-1a2b3c4d”                   }，                   {                       “EbsOptimized”：false，                       “NetworkInterfaces”：[                           {                               “SubnetId”：“subnet-a61dafcf”，                               “DeviceIndex”：0，                               “DeleteOnTermination”：false，                               “AssociatePublicIpAddress”：是的，                               “SecondaryPrivateIpAddressCount”：0                           }                       ]                       “InstanceType”：“r3.8xlarge”，                       “ImageId”：“ami-1a2b3c4d”                   }               ]               “SpotPrice”：“0.05”，               “IamFleetRole”：“arn：aws：iam :: 123456789012：role / my-spot-fleet-role”           }，           “SpotFleetRequestState”：“活跃”       }，       {           “SpotFleetRequestId”：“sfr-306341ed-9739-402e-881b-ce47bEXAMPLE”，           “SpotFleetRequestConfig”：{               “TargetCapacity”：20，               “LaunchSpecifications”：[                   {                       “EbsOptimized”：false，                       “NetworkInterfaces”：[                           {                               “SubnetId”：“subnet-6e7f829e”，                               “DeviceIndex”：0，                               “DeleteOnTermination”：false，                               “AssociatePublicIpAddress”：是的，                               “SecondaryPrivateIpAddressCount”：0                           }                       ]                       “InstanceType”：“m3.medium”，                       “ImageId”：“ami-1a2b3c4d”                   }               ]               “SpotPrice”：“0.05”，               “IamFleetRole”：“arn：aws：iam :: 123456789012：role / my-spot-fleet-role”           }，           “SpotFleetRequestState”：“活跃”       }   ] }

Answer 1

不完全确定你的意思，但是这个：

echo "$json" | grep -o '\(SpotFleetRequestId\|ImageId\): [0-9A-Za-z-]\+' | uniq

产生这个：

SpotFleetRequestId: sfr-73fbd2ce-aa30-494c-8788-1cee4EXAMPLE
ImageId: ami-1a2b3c4d
SpotFleetRequestId: sfr-306341ed-9739-402e-881b-ce47bEXAMPLE
ImageId: ami-1a2b3c4d
