自动缩放时如何更改新的实例标签名称 [英] How to change new instance tag Name when auto scaling

问题描述

我已根据我也创建的指标在 AWS 帐户上创建了一个新的警报. 我使用此警报自动缩放.启动新实例时，我使用User Data字段设置此新实例. 我面临的唯一问题是我无法修改此新实例的标签(特别是标签 Name ). 如果我不进行更改，则所有新实例的名称都将与当前设置不兼容.

I've created a new Alarm on my AWS account based on a Metric that I also have created. I use this alarm to auto scale. When launching new instances I'm using User Data field to set up this new instance. The only problem I'm facing is that I cannot modify the tags (specially the tag Name) of this new instance. If I don't change that, all the new instances will have the same name which won't work with my current setup.

有可能解决吗?

推荐答案

您可以使用AWS cli工具和实例元数据在其自己的用户数据脚本中为该实例设置新的Name标签.看起来像这样:

You can set up a new Name tag for the instance in its own user data script using AWS cli tools and the instance metadata. It would look like this:

aws ec2 create-tags \
  --resources $(curl -s http://169.254.169.254/latest/meta-data/instance-id) \
  --tag Key=Name,Value=MyNewNiceName \
  --region=us-east-1

请参阅: http://docs.aws. amazon.com/cli/latest/reference/ec2/create-tags.html
