Question

我正在尝试通过boto3运行Amazon EC2上已经存在的实例。

//! Allows subcomponents to gain access to model component
class CDbMappingComponentAware {
  public:
    //! Destructor (added for 1st warning)
    // virtual ~CDbMappingComponentAware() {}

    //! Set the corresponding component
    virtual void setMappingComponent(CDbMappingComponent *component);
...
...

但在这一行

df5 = df5.append({'Q':'Q', 'R':'Q', 'S':'Q'}, ignore_index=True)

我收到错误

import sys
import boto3


instance_id = "i-03e7f6391a0f523ee"
action = 'ON'

ec2 = boto3.client('ec2')

if action == 'ON':
   response = ec2.start_instances(InstanceIds=[instance_id], DryRun=False)
else:
    response = ec2.stop_instances(InstanceIds=[instance_id], DryRun=False)
print(response)


#resp2=ec2.describe_instances()
#foo = response['Reservations'][0]['Instances'][0]['NetworkInterfaces'][0]['Association']['PublicDnsName']
#filter=[{'Name':'Association','Values':['PublicDnsName']}]

#print (foo)
#instance = ec2.resource('ec2').instance(instance_id)
#while instance.state['Name'] not in ('running', 'stopped'):
#        sleep(5)
#        print("the instance is initializing")
x2=boto3.resource('ec2')
instance=x2.Instance('instance_id')
foo=instance.wait_until_running('self',Filters=[{'Name':'instance-state-name','Values':['running']}])
print ("instance.wait_until_running('self',Filters=[{'Name':'instance-state-name','Values':['running']}]) = "+foo)

这里使用

有什么问题？

foo=instance.wait_until_running('self',Filters=[{'Name':'instance-state-name','Values':['running']}])

我只是想了解此处提到的属性如何可用 https://boto3.readthedocs.io/en/latest/reference/services/ec2.html#instance 可以在程序中使用。我无法使用的诸如File "E:\installation2\python3\lib\site-packages\boto3\resources\factory.py", line 369, in do_waiter waiter(self, *args, **kwargs) File "E:\installation2\python3\lib\site-packages\boto3\resources\action.py", line 202, in __call__ response = waiter.wait(**params) File "E:\installation2\python3\lib\site-packages\botocore\waiter.py", line 53, in wait Waiter.wait(self, **kwargs) File "E:\installation2\python3\lib\site-packages\botocore\waiter.py", line 313, in wait last_response=response botocore.exceptions.WaiterError: Waiter InstanceRunning failed: Invalid id: "instance_id"之类的方法。

好，我解决了由于使用

而引起的问题

instance=x2.Instance('instance_id')

它应该像这样使用

instance=x2.Instance(instance_id)

botocore.exceptions.WaiterError：服务员InstanceRunning失败：无效的ID：“ instance_id”
