阅读此问题How to SSH and run commands in EC2 using boto3?
后，我尝试使用class TreeNode(val n: Int, val points: Array[Double],
val center: Double) extends Tree{
override def elem: TreeNode = ??? // write here your implementation instead of "???"
}
在EC2实例上自动运行命令。但是，当我写这样的代码时
SSM它提醒我
def excute_command_on_instance(client, command, instance_id):
response = client.send_command(
DocumentName="AWS-RunShellScript", # One of AWS' preconfigured documents
Parameters={'commands': command},
InstanceIds=instance_id,
)
return response
# Using SSM in boto3 to send command to EC2 instances.
ssm_client = boto3.client('ssm')
commands = ['echo "hello world']
instance_id = running_instance[0:1]
excute_command_on_instance(ssm_client, commands, instance_id)
。
使用botocore.exceptions.ClientError: An error occurred (AccessDeniedException) when calling the SendCommand operation: User: arn:aws:iam::62771xxxx946:user/Python_CloudComputing is not authorized to perform: ssm:SendCommand on resource: arn:aws:ec2:eu-west-2:6277xxxx3946:instance/i-074f862c3xxxxfc07
生成SST的凭据后，我得到了如下代码。
client然而，这次它让我想起了
def excute_command_on_instance(client, command, instance_id):
response = client.send_command(
DocumentName="AWS-RunShellScript", # One of AWS' preconfigured documents
Parameters={'commands': command},
InstanceIds=instance_id,
)
return response
# Using SSM in boto3 to send command to EC2 instances.
sts = boto3.client('sts')
sts_response = sts.get_session_token()
ACCESS_KEY = sts_response['Credentials']['AccessKeyId']
SECRET_KEY = sts_response['Credentials']['SecretAccessKey']
ssm_client = boto3.client(
'ssm',
aws_access_key_id=ACCESS_KEY,
aws_secret_access_key=SECRET_KEY,
)
commands = ['echo "hello world']
instance_id = running_instance[0:1]
excute_command_on_instance(ssm_client, commands, instance_id)
有谁能告诉我如何解决这个问题？

您缺少IAM用户或访问SSM的角色的权限。
您还尝试使用STS来获取访问权限，这使您需要执行的操作过于复杂。 STS需要承担的策略需要相同的权限。使用STS（最小特权规则）有很多好的案例，但我认为你不需要STS。
亚马逊为SSM提供了预定义的策略，您可以将其快速添加到策略或角色中，例如：
AmazonEC2RoleForSSM
AmazonSSMFullAccess
AmazonSSMReadOnlyAccess
