f8s 0.2.2

Framework for building K8s-ready Flask applications.

Introduction

Framework for building K8s-ready Flask applications.

See documentation for details.

Installation

Python

pip install f8s

Docker

1. Install docker-desktop
2. docker pull theNewFlesh/f8s:[version]

Docker For Developers

1. Install docker-desktop
2. Ensure docker-desktop has at least 4 GB of memory allocated to it.
3. git clone [e-mail]:theNewFlesh/f8s.git
4. cd f8s
5. chmod +x bin/f8s
6. bin/f8s docker-start

The service should take a few minutes to start up.

Run bin/f8s --help for more help on the command line tool.

ZSH Setup

1. bin/f8s must be run from this repository's top level directory.

2. Therefore, if using zsh, it is recommended that you paste the following line in your ~/.zshrc file:

   • alias f8s="cd [parent dir]/f8s; bin/f8s"
   • Replace [parent dir] with the parent directory of this repository

3. Running the zsh-complete command will enable tab completions of the cli commands, in the next shell session.

   For example:

   • f8s [tab] will show you all the cli options, which you can press tab to cycle through
   • f8s docker-[tab] will show you only the cli options that begin with "docker-"

Quickstart Guide

This repository contains a suite commands for the whole development process. This includes everything from testing, to documentation generation and publishing pip packages.

These commands can be accessed through:

• The VSCode task runner
• The VSCode task runner side bar
• A terminal running on the host OS
• A terminal within this repositories docker container

Running the zsh-complete command will enable tab completions of the CLI. See the zsh setup section for more information.
