terraform aws: Incorrect protocol in creating a security group-CodePudding

I have the following aws_security_group I would like to implement with terraform:

resource "aws_security_group" "ort_to_db" {
  name   = "MySQL/AURORA"
  vpc_id = data.aws_vpc.vpc_ort.id
 

  ingress {
    from_port   = 3306
    to_port     = 3306
    protocol    = "MYSQL/Aurora"
    cidr_blocks = ["0.0.0.0/0"]
  }

  egress {
    from_port   = 0
    to_port     = 0
    protocol    = -1
    cidr_blocks = ["0.0.0.0/0"]
  }
}

However, I'm receiving the following error on terraform apply:

Error: updating Security Group ingress rules: authorizing Security Group (ingress) rules: InvalidParameterValue: Invalid value 'mysql/aurora' for IP protocol. Unknown protocol. │
status code: 400, request id: d0

I've been checking from the

You are looking at the wrong field, the protocol type is TCP, and you were looking at the Type field. You can see in the screenshot it is greyed out and says TCP. The

CodePudding user response：

I think aws_security_group accept only the basic protocols Like TCP or UDP... If you are using MySQL just use TCP because that's what MySQL use.
