descry

A Github Action-Based CLI code executor for dynamic deployment of code.

This project is built upon RedL0tus' rifling rust crate, handling the Github Webhook Parsing.

Installation

Install the crate from cargo (this requires rust to be installed)

cargo install descry

Once installed, simply run

descry -c <file>.yaml

Where <file> represents the name of the configuration file. For a reference configuration file, see descry.yaml in the projects root directory.

Getting Started

First things first, you will need to get your webhook setup! You will need to go to the repo you wish to deploy descry to, go to settings, followed by webhooks and Add Webhook.

Then, in your payload URL - you will need to put where you have deployed descry to. It is suggested to use a service such as nginx to map your port deployment to a /hook subroute. I.e. https://reseda.app/hook. Leave the type as url-encoded.

Lastly, you will need to generate a secret. This should never be exposed. An example of what one should look like is shown in descry.yaml. This needs to be put in your yaml config wherever descry is deployed.

Then, simply chose what events you want this hook to listen to and activate it!

Documentation

The descry.yaml file contains everything needed for this project, lets walk through it.

Settings

• ip:port host: Host defines the location where descry will try to deploy itself. If you need a custom port, specify it here.
• string secret It's your action secret!
• bool print_commands Leave this as true if you wish to keep a log of any commands run.
• bool exit_on_error Should descry quit when recieving an error?

Events

Every event is the name it is given from GitHub. The following supported tags are:

Tag	Meaning	RunType
common	Is common to all events, is run on every action, as well as the action's specific tag.	on-every
all	Same as common.	on-every
push	Run on push.	on-specific
watch	Run on every new user watching repository, to find out who; check the hydrated tags.	on-specific
ping	Run on GitHub Action ping command, useful for testing.	on-specific
else	Anything... else...	on-specific

Inside, you can put bash code (.sh) that will be run whenever the event is called. The following properties can be used, which will be hydrated upon event run:

• {id} ID of the action
• {event} Action's event type
• {signature} Action's signature
• {payload} Action's payload content
• {request_body} Action's request body

What could I build with this?

There's infinite possibilities, but here's a few suggestions to get the ball rolling!

• Build &/or deploy code on a succesful commit to master.
• Notify your server of a new watcher, or stargazer; thank them!
• Keep yourself (and others) up to date with changes to the repo, like issues or stars.
• Let everyone know about a new version release!
• Many more!
