This is nothelm.py

Don't compare this to Kubernetes Helm (just yet?).

This is a templating engine meant to be used with Docker Stacks with a similar (not equal) experience to installing Helm Charts in Kubernetes with regards to templating support.

Install

pip3 install https://github.com/neuroforgede/nothelm.py/archive/refs/heads/master.zip

Usage

nothelm.py works different to Helm. Commands are implemented as arbitrary bash scripts in a special commands folder. A deploy command would be executed as follows:

nothelm run --values=test_values/values.yaml -p project deploy

The actual usage can be looked up via help and may change in future versions:

nothelm --help
Usage: nothelm [OPTIONS] COMMAND [ARGS]...

  nothelm.py

Options:
  --help  Show this message and exit.

Commands:
  run  runs a command

Project Structure

nothelm.py currently supports the following structure:

├── project
│   ├── commands
│   │   ├── deploy.sh.j2            # commands to run on your deployment
│   ├── templates   
│   │   └── sample-stack.yml.j2     # your deployment template data goes here
│   └── values.yaml                 # default values for use in the templates

Where can I find charts?

You can find charts here: https://github.com/neuroforgede/nothelm-charts . Since we don't have any concept of packaging defined yet, you will have to vendor these files into your own repository.

Why?

Override files in Docker Stacks are fine, but not enough. This project aims to have a fully templateable project structure centered around Docker Stack files.

You can probably use this to deploy other things as well (the entrypoint will be a bash script), but this project will be centered around Docker Stacks.
