[英]With boto, how can I name a newly spawned EC2 instance?
I'm using boto to spawn a new EC2 instance based on an AMI.我正在使用 boto 生成一个基于 AMI 的新 EC2 实例。
The ami.run method has a number of parameters, but none for "name" - maybe it's called something different? ami.run 方法有许多参数,但没有用于“名称”的参数 - 也许它被称为不同的东西?
import boto
c = boto.connect_ec2(ec2_key, ec2_secret)
image = c.get_image(ec2_ami)
reservation = image.run(key_name=ec2_keypair,
security_groups=ec2_secgroups,
instance_type=ec2_instancetype)
instance = reservation.instances[0]
c.create_tags([instance.id], {"Name": instance_name})
In EC2 there's no api to change the actually name of the machine.在 EC2 中,没有 api 可以更改机器的实际名称。 You basically have two options.
你基本上有两个选择。
ec2-create-tags <instance-id> --tag:Name=<computer name>
.ec2-create-tags <instance-id> --tag:Name=<computer name>
。 Downside to this solution is the server wont actually update to this name. Generally speaking if you're at the point where you want your server to configure itself when starting up I've found that renaming your computer in EC2 just causes more trouble than it's worth.一般来说,如果您希望您的服务器在启动时自行配置,我发现在 EC2 中重命名您的计算机只会带来更多的麻烦。 I suggest not using them if you don't have to.
如果没有必要,我建议不要使用它们。 Using the tags or elb instances is the better way to go.
使用标签或 elb 实例是更好的方法。
For those who are looking for the boto3
version of @Roberto 's answer:对于那些正在寻找 @Roberto 答案的
boto3
版本的人:
ec2 = boto3.resource('ec2')
ec2.create_tags(Resources=[instance.id], Tags=[
{
'Key': 'Name',
'Value': instance_name,
},
])
