[英]How to sort results from `list-tasks` in aws-cli?
I have few tasks running i want to get the latest(task which started last, with last created-at) task arn.我有几个任务正在运行,我想获得最新的(最后开始的任务,最后创建的)任务 arn。 I am using this command
我正在使用这个命令
aws ecs list-tasks --cluster {cluster} --family {family} --desired-status 'STOPPED'
after exploring a little i got to know about sort_by
.经过一番探索后,我了解了
sort_by
。 I tried我试过了
aws ecs list-tasks --cluster {cluster} --family {family} --desired-status 'STOPPED' --query "sort_by(taskArns, &CreatedAt)"
But this gives error但这会产生错误
In function sort_by(), invalid type for value: <some_task_arn>, expected one of: ['string', 'number'], received: "null"
Assuming you work from a Linux/Unix-Shell I would suggest sending the output to the sort command.假设您使用 Linux/Unix-Shell 工作,我建议将 output 发送到排序命令。 This works by adding
这通过添加
| sort
to your command at the end of the line:在行尾的命令:
aws ecs list-tasks --cluster {cluster} --family {family} --desired-status 'STOPPED' | sort
I hope this helps.我希望这有帮助。
list-tasks
will not give you that information. list-tasks
不会为您提供该信息。 Have to use both list-tasks
and describe-tasks
.必须同时使用
list-tasks
和describe-tasks
。
I will provide example on my cluster , with RUNNING
state tasks.我将在我的集群上提供示例,其中包含
RUNNING
state 任务。 You will have to adjust it to your need .您必须根据需要对其进行调整。
1. Get the list of tasks 1.获取任务列表
task_arns=$(aws ecs list-tasks --cluster ${cluster[Name]} \
--desired-status 'RUNNING' \
--query 'taskArns' --output text)
echo ${task_arns}
Should give a list of Arns of your tasks, eg:应该给出你的任务的 Arns 列表,例如:
arn:aws:ecs:us-east-1:275795381673:task/0053c603-a6c9-4044-89f5-b0edc8f6de3f arn:aws:ecs:us-east-1:275795381673:task/0b4626ea-0f2b-4c99-9e90-010e8a0c8ad3 arn:aws:ecs:us-east-1:275795381673:task/0d4aa5f2-f547-45ad-b1f8-ed84ef1d678c arn:aws:ecs:us-east-1:275795381673:task/190a320f-4b68-497a-921e-439460447d45 arn:aws:ecs:us-east-1:275795381673:task/c979f4a2-3665-4c56-93c6-e9b88f6b3519
2. Get sorted tasks Arns 2. 获取排序任务 Arns
aws ecs describe-tasks --cluster ${cluster[Name]} \
--tasks ${task_arns} \
--query "tasks[] | reverse(sort_by(@, &createdAt)) | [].[createdAt,taskArn]" \
--output table
Should give, eg:应该给,例如:
----------------------------------------------------------------------------------------------------
| DescribeTasks |
+----------------+---------------------------------------------------------------------------------+
| 1589888493.15 | arn:aws:ecs:us-east-1:275795381673:task/c979f4a2-3665-4c56-93c6-e9b88f6b3519 |
| 1589888501.348| arn:aws:ecs:us-east-1:275795381673:task/190a320f-4b68-497a-921e-439460447d45 |
| 1589888499.438| arn:aws:ecs:us-east-1:275795381673:task/0d4aa5f2-f547-45ad-b1f8-ed84ef1d678c |
| 1589888500.312| arn:aws:ecs:us-east-1:275795381673:task/0b4626ea-0f2b-4c99-9e90-010e8a0c8ad3 |
| 1589888497.701| arn:aws:ecs:us-east-1:275795381673:task/0053c603-a6c9-4044-89f5-b0edc8f6de3f |
+----------------+---------------------------------------------------------------------------------+
3. Get last element sorted tasks Arns 3. 获取最后一个元素排序的任务 Arns
aws ecs describe-tasks --cluster ${cluster[Name]} \
--tasks ${task_arns} \
--query "tasks[] | reverse(sort_by(@, &createdAt)) | [-1].[taskArn]" \
--output text
Should give:应该给:
arn:aws:ecs:us-east-1:275795381673:task/0053c603-a6c9-4044-89f5-b0edc8f6de3f
