I currently have a lambda function which is inside a Private VPC because I am using it to access a ElasticCache Redis Cluster. However, I am unable to make https requests because of the private VPC. I have greated a NAT gateway with one of the subnets but all https requests time out. Should I be creating a second lambda function? How should I be doing this?
CodePudding user response：
The configuration should be:
- NAT Gateway connected to a public subnet
- AWS Lambda function connected to a private subnet
- Private subnet Route Table configured to point to the NAT Gateway for
0.0.0.0/0destination - Security Group on the Lambda function with "Allow All" Outbound rules

Adding ip address of the server you are trying make an https to, to the outbound rules of the security group might help. The outgoing request must've been disabled.
