AWS Lambda函数未加入VPC

我正在尝试连接到我的AWS Aurora数据库.遵循文档指南3次以上，我在mysql connetiontion上收到相同的超时错误.深入研究之后，看来我的lambda函数根本就没有加入VPC.

I am trying to connect to my AWS Aurora DB. Following the documentation guide 3 times over I recieved the same timeout error on the mysql connetiontion. After digging in, it seems that my lambda function is simply not joining the VPC.

我将列出一些输出(删除了不必要的行)以显示我是如何得出这个结论的.

I will list some outputs (with unnecessary lines removed) to show how I came to this conclusion.

如果任何人都可以指出我的配置哪里出了问题.请告诉我.在任何人提到它之前，是的，我已经检查了db程序变量很多次.这一定是配置问题.

If anyone can point out where I went wrong in my configuration. Please let me know. Before anyone mentions it, yes, I have checked the db program variables many times; it has to be a configuration issue.

IP地址python代码:

IP Address python code:

import socket
response = socket.gethostbyname('test.db')
logger.log("test.db IP: " + response)

import subprocess
command = "/sbin/ip addr show"
process = subprocess.Popen(command, stdout=subprocess.PIPE, stderr=None, shell=True)
response = process.communicate()
logger.error("IP command: " + response[0])

IP地址输出:

       valid_lft forever preferred_lft forever

如您所见，由于某种原因，我得到的是169.254.x.x地址而不是VPC的172.31.x.x.还需要注意的是，数据库是同一VPC中同一安全组的一部分.

As you can see, for some reason I am getting 169.254.x.x address instead of the VPC's 172.31.x.x. Also to note is that the DB is apart of the same security group in the same VPC.
