## About the Repo
This repo shows the development state of the Wolkstack project, a cloud development framework for 

Despite being available on github, this repository is intended as a read-only resource and has been licensed as such. Permissions are not given to use or modify this software.

## Getting Started
Wolkstack requires several steps and infrastructure pieces to be setup for optimal usage, the exact steps to install the below software will not be included in this documentation, although tutorials can be found on the provided pages.

Required programs:
- [KubeCTL](https://kubernetes.io/docs/tasks/tools/install-kubectl/)
- [AWS CLI](https://docs.aws.amazon.com/cli/latest/userguide/cli-chap-install.html)
- [Terraform](https://learn.hashicorp.com/tutorials/terraform/install-cli)
- [Helm](https://helm.sh/docs/intro/install/)
- [Python](https://www.python.org/downloads/)

With this complete some pre-steps are required to ensure that credentials are generated in your project.

### AWS CLI 
Ensure that you have run `aws configure` and set your authentication credentials locally in your computer

### Environment Credentials
Terraform requires some basic credentials to run CI/CD services on your AWS account, the exact commands to set these are shown below.

This code makes use of environment variables to ensure that the user does not expost information, additionally credentials are encrypted and made use of with AWS parameter store, a secure repository for this use case.

#### Docker-Hub
To deploy containers and install applications we need a docker-hub credential which can be set with:

export TF_VAR_docker_hub_password={password}

#### Github
To setup web-hooks and access code for CI/CD on your private repositories, how to get the [token](https://docs.github.com/en/free-pro-team@latest/github/authenticating-to-github/creating-a-personal-access-token):

export TF_VAR_github_token={token}
  
### Install
Wolkstack is available as a simple [PyPi package](https://pypi.org/project/Wolkstack/)
and can be installed with command `pip install Wolkstack`

Once installed steps and commands can be followed inside the Wolkstack CLI.
