This is simple TF code that consume git submodule for community provider plugin. The main goal is in one git repository's folders to link another git repository. In our case we link a community plug in shell (https://github.com/scottwinkler/terraform-provider-shell) so we can reuse it in multiple repositories but upload it one and thus save space.

These instructions will get you a example of how to use git submodule combine with TF code.

Software needed to be installed:

• git -> https://git-scm.com/downloads
• terraform -> https://www.terraform.io/downloads.html

First step is to clone this repository. Open you terminal according to your OS, change to your working directory and perform the following command:

Say what the step will be

git clone --recurse-submodules https://github.com/yaroslav-007/17447.git

When repository is cloned change your directory to the repo folder

cd 17447

To test if the code and clone of the github repo successful, we should run terraform init. This should initiate terraform and find all plug ins included the shell plugin deployed as git submodule

Run terraform init

terraform init

If everything is ok the output of the initiation should be:

Terraform has been successfully initialized!

We can check if the shell plugin is loaded:

 terraform providers 
.
├── provider.null
└── provider.shell

• Two repos were created: 17447 and 17447-module. The firsts one contains the tf code and the second community provider shell.
• To add the git submodule 17447-module in the main repo 17447, you perform the following command in your local cloned 17447: git submodule add <url to the submodule repo> <the path in your main repo where the submodule will be 'mounted">

git submodule add https://github.com/yaroslav-007/17447-module.git terraform.d/plugins

• A new directory (in our case terraform.d ) will be created accordingly and new file named .gitmodules containing information regarding git submodule info. Commit those two files to the main repo.
