Environment Terraform: 0.12.3

Problem

Trying to initialize terraform with terraform-google-consul module version of 0.4.0 - https://github.com/hashicorp/terraform-google-consul/releases/tag/v0.4.0

Getting an error on terraform init:

Here is the snippet of my main.tf file referencing a module:

# ---------------------------------------------------------------------------------------------------------------------
# DEPLOY THE CONSUL SERVER CLUSTER
# Note that we make use of the terraform-google-consul module!
# ---------------------------------------------------------------------------------------------------------------------

module "consul_cluster" {
  source = "git::git@github.com:hashicorp/terraform-google-consul.git//modules/consul-cluster?ref=v0.4.0"
  #source = "git::git@github.com:hashicorp/terraform-google-consul.git//modules/consul-cluster?ref=v0.2.1"

  subnetwork_name = "${google_compute_subnetwork.private_subnet_with_google_api_access.name}"

Not sure what's going on here..

Weird! Try again once this PR is merged though #44 and then we will have a look

Hi, We are seeing the same thing using terraform v0.12.6.

We are using terraform on windows and we are getting this error if we use SSH, when we change the source to use HTTPS it works.

This does not work

module "test" {
  source = "git::ssh://github.test.io/test/test.git"
}

This works

module "test" {
  source = "git::https://github.test.io/test/test.git"
}

Using git command manually works perfectly. I was suspecting this to be a windows-only problem?

Hi,

Having the same issue here. Terraform 0.12.8. Windows 10 1903.

HTTPS works: module "tags" { source = "git::https://git@github.com/CompanyName/blah-terraform-modules.git//tags?ref=develop"

SSH fails: module "tags" { source = "git@github.com:CompanyName/blah-terraform-modules.git//tags?ref=develop"

Git works standalone to drag these items over ssh using my ssh key that is set systemwide. Github Desktop also works for ssh using that same key.

I can only assume that Terraform's call for git is doing something funky with ssh. Doesn't appear to be any debugging that can be done as it's all encapsulated with Terraform.

Does appear to be windows only, all my colleagues are using Linux with the same tf files without issues.

Found a way to get this working. After looking at the Terraform source and other references to this issue, it appears that Terraform needs an environment variable for 'GIT_SSH_COMMAND' instead-of/in-addition-to 'GIT_SSH'.

In addition to this, the implementation of GIT_SSH_COMMAND isn't Windows friendly, so it needs the path to ssh.exe to be escaped for \ characters. The final value therefore is the below.

GIT_SSH_COMMAND = C:\\Windows\\System32\\OpenSSH\\ssh.exe

All other config remained the same as per my previous comment.

If someone from Hashicorp reads this, it could do with being much more obvious (documented) and possibly a better design for Windows.

This approach worked for me on windows. I had to run set GIT_SSH_COMMAND=C:\\Windows\\System32\\OpenSSH\\ssh.exe since i use cmder, but thanks for this!

Hi, I'm seeing the same issue running TF 0.12.21, Ubuntu 16.04.

If you're only seeing the issue with Windows, then you are probably seeing what I have discussed here: https://github.com/hashicorp/terraform/issues/19232#issuecomment-620894910

I use pagent, so my env var had to be

GIT_SSH_COMMAND=C:\\Program\ Files\\PuTTY\\plink.exe

[ADTC]

This was definitely a problem for me on Windows. To get the SSH working with Terraform, I had to do:

set GIT_SSH_COMMAND=C:\\Windows\\System32\\OpenSSH\\ssh.exe

If you're not sure where your ssh.exe is, try:

where ssh

Note, the above set command only applies in the current session. To apply globally, you need to edit your system or user environment variables.
