terraform aws ec2 ssh

Question

I have this terraform script:

provider "aws" {
  region = "us-weast-1"
}


resource "aws_security_group" "allow_all" {
  name        = "allow_all"
  description = "Allow all inbound traffic"


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

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

  vpc_id = "vpc-154c1701"

}


resource "aws_instance" "wso2-testing" {
  ami           = "ami-0f9cf087c1f27d9b1"
  instance_type = "t2.small"
  key_name = "mykeypair"
  vpc_security_group_ids = ["${aws_security_group.allow_all.id}"]

    }

The machine is created correctly, but i can´t connect to ec2 instance using my key pair with ssh. Always i have the error:

ssh: connect to host x.x.x.x port 22: Operation timed out

The VPC es aws default with internet gateway

Did you try with protocol = "all" as well? To be honest, I don't see any error in the script if id values are correct — Pubudu Jayawardana
Your security group has a VPC-ID but your instance does not. Is this private IP or public IP instance. My recommendation is to remove the VPC from the instance or assign the default VPC to both. The issue could be your VPC, Subnet, NACLs, ... — victor m
There's also a typo in your provider "aws" block: us-weast-1 should be us-west-1 — Adil B

You can add your own IP to security group using below snippet:

data "http" "myip"{
    url = "https://ipv4.icanhazip.com"
}

ingress {
        # TCP (change to whatever ports you need)
        from_port   = 0
        to_port     = 0
        protocol    = "-1"
        # Please restrict your ingress to only necessary IPs and ports.
        # Opening to 0.0.0.0/0 can lead to security vulnerabilities.
        cidr_blocks = ["${chomp(data.http.myip.body)}/32"]
      }

egress {
        # Outbound traffic is set to all
        from_port       = 0
        to_port         = 0
        protocol        = "-1"
        cidr_blocks     = ["0.0.0.0/0"]
    }
