# Terrareg



Open source Terraform Registry.



Provides features to aid usage and discovery of modules, providing:



 * Fully implemented Terraform modules API

 * Completely API driven for automating all features

 * Host Terraform modules internally or from an external Git source

 * Analytics about the usage of modules

 * All information about a module - README, inputs, outputs, provider requirements and managed resources

 * Security alerts for each module, submodule and examples

 * Cost estimation for each module example

 * Module example source code within the UI, with automatic rewriting of 'source' arguments

 * Interactive 'Usage builder', helping users build terraform to use the terraform modules

 * Hooks for git SCM applications to automatically index modules

 * Authentication via SSO (OpenIDConnect/SAML2) and GitHub

 * Terraform provider support (very early alpha version)



If you like and use this project and are happy to let us know, please raise a GitHub issue, create a PR or contact [MatthewJohn](https://github.com/matthewjohn) so it can be added to the README :)

## Getting started



    # Create secret key for session data

    export SECRET_KEY=$(python -c 'import secrets; print(secrets.token_hex())')



    # Run container, specifying secret key and admin password

    docker run -ti -p 5000:5000 \

        -e PUBLIC_URL=http://localhost:5000 \

        -e MIGRATE_DATABASE=True \

        -e SECRET_KEY=$SECRET_KEY \

        -e ADMIN_AUTHENTICATION_TOKEN=MySuperSecretPassword \

        ghcr.io/matthewjohn/terrareg:latest



The site can be accessed at http://localhost:5000, which will provide a 'Initial Setup' guide for getting started.



For information about running with docker-compose, SSL certificate generation or running without docker, see [docs/LOCAL_DEVELOPMENT.md](./docs/LOCAL_DEVELOPMENT.md).



## Upload a terraform module:



**Warning**: Terrareg downloads and analyses modules. Be careful when using untrusted modules or modules that use untrusted Terraform providers, as this can allow arbitrary code execution.



### From a git repo



* Goto http://localhost:5000

* Login, using the button in the top-right hand corner

* Goto 'Create' -> 'Namespace' (http://localhost:5000/create-namespace)

  * Provide a name for the namespace and create.

* Goto 'Create' -> 'Modules' (http://localhost:5000/create-module)

* Fill in the details for your module and 'Create'

* Use the 'Manually index version' form of your module, filling out the version and select 'Publish' and then press 'Index Version'



### From source



    terrareg_root=$PWD

    

    cd source/of/my/module

    

    # OPTIONAL: Create an terrareg meta-data file

    echo '{ "description": "My first module", "owner": "ME!", "source": "https://github.com/me/my-tf-module" }' > ./terrareg.json

    

    # Zip up module

    zip -r ../my-tf-module.zip *

    

    # Upload to terrareg

    bash $terrareg_root/scripts/upload_module.sh http://localhost:5000 helloworld my-tf-module aws 1.0.0 ../my-tf-module.zip



  Navigate to http://localhost:5000 to get started, or http://localhost/modules/helloworld/my-tf-module to see the uploaded example!



**NOTE:** To use modules from the registry in Terraform, a valid SSL certificate is incredibly highly recommended. Terraform will not work if you supply `http://` as a protocol for the module URL, as it will treat this as a direct HTTP download, rather than treating it as a registry. Whilst Terrareg does handle these types of requests, you will not be able to the module version ranges that Terraform provides.



## Additional configuration



For a full list of environment variables, please see [Deployment Guide](https://matthewjohn.github.io/terrareg/deployment) and [docs/CONFIG.md](https://matthewjohn.github.io/terrareg/CONFIG)



## User Guide



For documentation about features, deployment, configuration and using Terrareg, please see: [https://matthewjohn.github.io/terrareg](https://matthewjohn.github.io/terrareg)



## Terraform Provider



The Terrareg Terraform provider can be used to create namespaces, modules and manage other aspects of Terrareg:



 * [https://registry.terraform.io/providers/dockstudios/terrareg](https://registry.terraform.io/providers/dockstudios/terrareg)

 * [https://github.com/DockStudios/terraform-provider-terrareg](https://github.com/DockStudios/terraform-provider-terrareg)



## Upgrading



For notes on upgrading, please see: [https://matthewjohn.github.io/terrareg/UPGRADE](https://matthewjohn.github.io/terrareg/UPGRADE)



## API Documentation



See the [API Docs](./docs/API.md) for a list of all API endpoint.



## Changelog



See [CHANGELOG.md](CHANGELOG.md)



## Local development



For all installation about local development, see [https://matthewjohn.github.io/terrareg/LOCAL_DEVELOPMENT](https://matthewjohn.github.io/terrareg/LOCAL_DEVELOPMENT).



Since terraform requires HTTPS with a valid SSL cert, this must be provided in local development



On linux, by default, non-privileged users cannot listen on privileged ports, so the following can be used to route requests locally to port 5000:



```

sudo iptables -t nat -I OUTPUT -p tcp -d 127.0.0.1 --dport 443 -j REDIRECT --to-ports 5000

```



Example to run in local development environment:

```

virtualenv -ppython3.8 venv

. venv/bin/activate

pip install -r requirements.txt

pip install -r requirements-dev.txt
