GitHub Actions – Live Learning Notes

A large group of people have started using GitHub Actions. Mainly, as they are moving from Travis-CI for their GitHub repos. I already know how to use Travis-CI but never tried GitHub Actions before. I think it won’t take much time to learn its basics. So let’s dive into it.

I can’t find a better introduction for this than their official docs: #1 https://docs.github.com/en/free-pro-team@latest/actions/learn-github-actions/introduction-to-github-actions

It cleared up a lot of terminologies, and by giving the working examples. They have made it a good introductory tutorial. Moving on the part two now: #2 https://docs.github.com/en/free-pro-team@latest/actions/learn-github-actions/finding-and-customizing-actions

I didn’t read #2 completely, want to read more about the syntax first #3 https://docs.github.com/en/free-pro-team@latest/actions/learn-github-actions/finding-and-customizing-actions

Just quickly skimmed through #3 YAML examples and headings of syntax.

Now, I think I should try implementing it on one of my project that was using Travis-CI so far. Here is my project #4 https://github.com/GeekyShacklebolt/nickoscope

Let me write a GitHub workflow file for it. In the project_root/.github/workflows/main.yml

name: Run Tests for Nickoscope

on: [push, pull_request]

jobs:
  build-and-run-tests:
    runs-on: ubuntu-latest
    steps:
      - name: Get Action V2
        uses: actions/checkout@v2

      - name: Setup Python
        uses: actions/setup-python@v2
        with:
          python-version: '3.8'

      - name: Install Requirements
        run: |
          python -m pip install --upgrade pip
          pip3 install -r requirements.txt

      - name: Run flake8
        run: |
          flake8

Commit this file and push to your repository.

I got YAML syntax error on the first attempt. -_-
Corrected it and pushed through a PR this time.

There we go. It is working!!!

Now, whenever I would have to use GitHub actions for some new requirements like new actions, services, etc, I can just read their official docs for that specific requirement.

Great then. Thanks for following up so far!
