many instances of a module (git) download from git each time

[gtmtech]

Terraform 0.11.1

I have a submodule which I instantiate several times e.g.:

module "foo_a" {
    source  = "git::ssh://[email protected]/mycompany/ha_asg.git"
}

module "foo_b" {
    source  = "git::ssh://[email protected]/mycompany/ha_asg.git"
}

module "foo_c" {
    source  = "git::ssh://[email protected]/mycompany/ha_asg.git"
}

Disappointingly when I run terraform init, this is very slow because for each of foo_a, foo_b, foo_c, etc. - terraform downloads the whole git source again. Can't it instead work out that it needs that source once, and download it once?

I run a terraform init on each terraform command, so the slowness is exacerbated a bit.

Thanks!

If you are using CI and make heavy use of modules, this adds a lot of time to each deploy. (Even if you do cache WORKING_DIRECTORY/.terraform/modules, which can sometimes present its own set of problems...)

Hi @gtmtech! Thanks for reporting this.

This seems to be the same thing being discussed over in #11435, so I'm going to close this just to consolidate the discussion over there.
