由于 cpu 单元不足和某些超时，ecs 部署失败

Question

我刚刚使用 pip install ecs-deploy 安装了 ecs-deploy。当我尝试部署时出现类似错误

我第一次得到：

Deploying based on task definition: task-demo:2

Creating new task definition revision
Successfully created revision: 3

Updating service
Successfully changed task definition to: task-demo:3

Deploying new task definition..........
2020-01-26 14:12:57.563000+00:00
ERROR: (service demo-service) was unable to place a task because no container instance met all of its requirements. The closest matching (container-instance ba93b620-89fa-4970-bf54-535a373d1aba) has insufficient CPU units available. For more information, see the Troubleshooting section of the Amazon ECS Developer Guide.

Deployment failed

从第二次开始：

Deploying based on task definition: task-demo:5

Creating new task definition revision
Successfully created revision: 6

Updating service
Successfully changed task definition to: task-demo:6

Deploying new task definition...................................................................................................................................................................................................................................................................................................
Deployment failed due to timeout. Please see: https://github.com/fabfuel/ecs-deploy#timeout

Answer 1

如果用于放置任务的最匹配容器实例没有足够的 CPU 单元来满足任务定义的要求，您会收到此错误消息。

您需要检查容器实例上剩余的 CPU 单元，并进行调整以满足 CPU 要求。

这是解决此问题的资源：

关于超时问题，请注意 ecs 命令的部署和扩展操作允许通过 --timeout 参数定义超时（以秒为单位）。这指示 ecs-deploy 等待 ECS 在给定的秒数内完成部署。

见https://github.com/fabfuel/ecs-deploy#deployment-timeout

先尝试修复 CPU 问题。超时问题很可能是相关的。
