对于遇到这个问题的未来开发人员，一个更新的方法是：
- 使用包含
AmazonEC2RoleforSSM 策略的角色创建您的 EC2
- 创建一个 lambda 来执行唤醒、运行命令、关机
- 使用 Cloudwatch 事件触发 lambda
所以：
按照此处的步骤操作：https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/iam-roles-for-amazon-ec2.html
使用以下 lambda 框架：
import time
import boto3
REGION_NAME = 'us-east-1'
WORKING_DIRECTORY = '<YOUR WORKING DIRECTORY, IF ANY>'
COMMAND = """
echo "Hello, world!"
"""
INSTANCE_ID = '<YOUR INSTANCE ID>'
def start_ec2():
ec2 = boto3.client('ec2', region_name=REGION_NAME)
ec2.start_instances(InstanceIds=[INSTANCE_ID])
while True:
response = ec2.describe_instance_status(InstanceIds=[INSTANCE_ID], IncludeAllInstances=True)
state = response['InstanceStatuses'][0]['InstanceState']
print(f"Status: {state['Code']} - {state['Name']}")
# If status is 16 ('running'), then proceed, else, wait 5 seconds and try again
if state['Code'] == 16:
break
else:
time.sleep(5)
print('EC2 started')
def stop_ec2():
ec2 = boto3.client('ec2', region_name=REGION_NAME)
ec2.stop_instances(InstanceIds=[INSTANCE_ID])
while True:
response = ec2.describe_instance_status(InstanceIds=[INSTANCE_ID], IncludeAllInstances=True)
state = response['InstanceStatuses'][0]['InstanceState']
print(f"Status: {state['Code']} - {state['Name']}")
# If status is 80 ('stopped'), then proceed, else wait 5 seconds and try again
if state['Code'] == 80:
break
else:
time.sleep(5)
print('Instance stopped')
def run_command():
client = boto3.client('ssm', region_name=REGION_NAME)
time.sleep(10) # I had to wait 10 seconds to "send_command" find my instance
cmd_response = client.send_command(
InstanceIds=[INSTANCE_ID],
DocumentName='AWS-RunShellScript',
DocumentVersion="1",
TimeoutSeconds=300,
MaxConcurrency="1",
CloudWatchOutputConfig={'CloudWatchOutputEnabled': True},
Parameters={
'commands': [COMMAND],
'executionTimeout': ["300"],
'workingDirectory': [WORKING_DIRECTORY],
},
)
command_id = cmd_response['Command']['CommandId']
time.sleep(1) # Again, I had to wait 1s to get_command_invocation recognises my command_id
retcode = -1
while True:
output = client.get_command_invocation(
CommandId=command_id,
InstanceId=INSTANCE_ID,
)
# If the ResponseCode is -1, the command is still running, so wait 5 seconds and try again
retcode = output['ResponseCode']
if retcode != -1:
print('Status: ', output['Status'])
print('StdOut: ', output['StandardOutputContent'])
print('StdErr: ', output['StandardErrorContent'])
break
print('Status: ', retcode)
time.sleep(5)
print('Command finished successfully') # Actually, 0 means success, anything else means a fail, but it didn't matter to me
return retcode
def lambda_handler(event, context):
retcode = -1
try:
start_ec2()
retcode = run_command()
finally: # Independently of what happens, try to shutdown the EC2
stop_ec2()
return retcode
