Small cli application to read environment variables from
Kubernetes' deployment.yaml, export them and run a command
in the "new" environment

**This is a WORK IN PROGRESS!!!**

Motivation
----------
I've been using Kubernetes for a while now and using environment variables
to configure my applications and each environment (staging, production, etc)
has got its own deployment.yaml and when the number of environment variables
grows past two it gets annoying to run an application locally pointing to a
different environment (e.g. staging).

So I decided to write this wee tool to do the "monkey job" of reading
the deployment.yaml and exporting the environment variables

Usage
-----

```sh
$ ./kubernetes-envvar <type: d|t> <filepath> <command and args>
```
Arguments:
* Type: It's either `t` or `d` depending on the structure of the yaml file.
  * `d` is for the simpler yaml (see [example/deployment.yaml](example/deployment.yaml))
  * `t` is for a helm yaml file (see [example/deploymentWithTemplate.yaml](example/deploymentWithTemplate.yaml))
* Filepath: Is the path to the Kubernetes' deployment.yaml
* Command: Is the command and it's args.

TODO
----

* Remove ugly workaround helm templates
* Parse/replace environment variables on the command and it's arguments
* Parse deployment.yaml in a more generic way
* Review the logging/debug messages
* Return the return code of the command run

An input argument to this GitHub Action is being exported as an environment variable. If a user of this action passes untrusted input, it could be used in an insecure manner by subsequent workflow steps.

What are GitHub Actions taint flows?

GitHub Actions: Input argument exported as environment variable

An input argument to this GitHub Action is being passed back as an output. If a user of this action passes untrusted input, it could be used in an insecure manner by consuming workflows.

GitHub Actions: Input argument passed back as output

An input argument to this GitHub Action flows into a dangerous sink (such as shell command execution). This could allow a malicious user to inject commands or exploit the action.
