我想获得一个任务定义列表，我可以通过 AWS CLI 创建一个列表。这是命令中的部分列表；aws ecs list-task-definitions --region eu-west-1
{
"taskDefinitionArns": [
"arn:aws:ecs:eu-west-1:543573289192:task-definition/audience-view-dev-api:4",
"arn:aws:ecs:eu-west-1:543573289192:task-definition/audience-view-dev-groups:4",
"arn:aws:ecs:eu-west-1:543573289192:task-definition/audience-view-dev-groups:5",
"arn:aws:ecs:eu-west-1:543573289192:task-definition/audience-view-dev-mock-api:1",
"arn:aws:ecs:eu-west-1:543573289192:task-definition/audience-view-dev-mock-responder:1"
]
}
从这里我只想展示;
audience-view-dev-api
audience-view-dev-groups
audience-view-dev-groups
audience-view-dev-mock-api
audience-view-dev-mock-responder
我相信如果我通过管道将其发送至
jq那么我可以得到我想要的东西吗？我正在尝试各种组合； aws ecs list-task-definitions --region eu-west-1 | jq -r '.taskDefinitionArns[].<something_here>'无济于事
最佳答案
尝试这个:
$ aws ecs list-task-definitions --region eu-west-1 \
| jq -Mr '.taskDefinitionArns[] | split(":")[5] | split("/")[1]'
扩展:
.taskDefinitionArns[] # for each taskDefinitionArns
| split(":")[5] # take entry [5] after splitting by :
| split("/")[1] # take entry [1] after splitting by /
