如何通过命令行在aws ecs集群中按比例缩小/放大容器,我应该使用aws cli还是ecs-cli? [英] How to scale down/up containers in aws ecs cluster by command line, should I use aws cli or ecs-cli?
问题描述
我正在使用EC2实例运行AWS ECS集群,并且我想要一个命令将任务扩展到1个正在运行的实例,然后在不需要时将其缩减到0.这应该破坏基础EC2实例以避免收费.我不使用Fargate,因为它不在免费套餐中.
I'm running AWS ECS cluster with EC2 instances and I want a command to scale up the tasks to 1 running instance and then after some time when I do not need it I want to scale it down to 0. This should destroy the underlying EC2 instance to avoid charges. I'm not using Fargate as it is not in free tier.
我目前正在使用什么来扩展到一个并开始运行它:
what I'm currently using to scale up to one and start running it:
ecs-cli scale --capability-iam --size 1 --cluster myEC2clusterName --region us-east-1
aws ecs run-task --cluster myEC2clusterName --region us-east-1 --task-definition myTaskDefinitionName:1 --count 1
我目前正在使用的缩小比例:
what I'm currently using to scale down:
ecs-cli scale --capability-iam --size 0 --cluster myEC2clusterName --region us-east-1
是否仅在aws cli中存在等效命令,而无需使用ecs-cli进行相同操作?
Is there an equivalent command only in aws cli without need to use ecs-cli to do the same?
推荐答案
是的,您可以调用 update-service
命令.
aws ecs update-service --cluster myEC2clusterName --region us-east-1 --service myServiceName --desired-count 0
我误解了这个问题.
您可以调用 SetDesiredCapacity
API或使用 set-desired-capacity
命令调整EC2自动伸缩组的大小.
You can call the SetDesiredCapacity
API or use the set-desired-capacity
command to adjust the size of your EC2 auto scaling group.
