terraform apply fails when supplying aws_instance connection key_file

[tonyjchong]

Here is an excerpt from my tf file.

resource "aws_instance" "linux" {
    ami = "${lookup(var.amis, var.region)}"
    instance_type = "t1.micro"
    count = 1
    key_name = "dev"
    connection {
        user = "core"
        key_file = "~/.ssh/dev.pem"
    }
}

Error applying plan:

1 error(s) occurred:

• Failed to read key file '~/.ssh/dev.pem': open ~/.ssh/dev.pem: no such file or directory.

Is there something I am doing incorrectly? I have been able to launch machines and now I'm testing out the different provisioners. Thanks!

The problem here is that terraform isn't expanding the tilde to your home directory.

terraform/helper/ssh/provisioner.go

Line 105 in ffc5d44

key, err := ioutil.ReadFile(conf.KeyFile)

specifically needs some code added.

In the short term you can work around it by expanding it to an absolute path yourself.

Thanks. Just for others to see, the tilde would be perfect so everyone on my team can develop and test out terraform since we all have the pem.

Thanks, this is a bug.
