# Cheat Sheet

This document contains an overview of fundamental concepts and terminology, you can use this as a reference book if you get lost in the terminology along the way.

## Github actions high level components

<img width="671" alt="image" src="https://user-images.githubusercontent.com/10853833/216319332-3d5529e8-abfc-4dab-b9b7-e55c4cba99e5.png">

## Yaml functions

| Function | Description |
|---------------------------------|-------------------------------------------------------------------------------------------------------|
| success() | Returns true if none of the previous steps have failed or been cancelled. |
| always() | Returns true even if a previous step was cancelled and causes the step to always get executed anyway. |
| cancelled() | Returns only true if the workflow was canceled. |
| failure() | Returns true if a previous step of the job had failed. |
| contains(search, item) | Returns true if search contains item. |
| startsWith(search, item) | Returns true if search starts with item. |
| endsWith(search, item) | Return true if search ends with item. |
| format('{0} {1}', item1, item2) | Replaces placeholders in a string. |
| join(array, separator) | All values in array are concatenated into a string using provided separator |
| toJSON(value) | Returns a pretty-print JSON representation of value. |
| fromJSON(value) | Returns a JSON object or JSON data type for value. |

## Workflow commands

See also:
https://docs.github.com/en/actions/using-workflows/workflow-commands-for-github-actions
Actions can communicate with the runner machine to set environment variables, output values used by other actions, add debug messages to the output logs, and other tasks.
Most workflow commands use the echo command in a specific format, while others are invoked by writing to a file.

Example echo workflow command:
```bash
echo "::workflow-command parameter1={data},parameter2={data}::{command value}"
```
Example write to file workflow command:
```bash
echo "SELECTED_COLOR=green" >> $GITHUB_OUTPUT
```

# Getting ready

## Step 1: Set up your GitHub.com account

For this class, we will use a public account on GitHub.com. We do this for a few reasons:

We don't want you to "practice" in repositories that contain real code.
We are going to break some things, so we can teach you how to fix them (therefore, refer to the line above).

You can set up your free account by following these steps:

* Access [GitHub.com](https://github.com) and click Sign up
* Choose the free account
* You will receive a verification email at the address provided
* Click the link to complete the verification process
* If you already have an account, verify that you can visit github.com within your organization's network.

GitHub is designed to run on the current versions of all major browsers. Take a look at our list of supported browsers.

## ⚡ Prerequisites

The workshop is designed for developers that have used other platforms like Azure DevOps, GitLab, or Bitbucket and now want to switch to GitHub. But it is also suitable for people that are new to topics like git, CI/CD, and DevOps.

For this workshop you need the following:

- A laptop (Windows, Mac, or Linux)
- A free account for https://github.com
- It is recommended to have a second screen for the hand-on labs

# 🔨 Hands-on: My first workflow

In this hands-on lab your will create your first GitHub Actions Workflow and learn how you can use Actions to automate tasks in your software development lifecycle. If you like more background information, please refer to the [GitHub Actions](https://docs.github.com/en/actions/learn-github-actions/understanding-github-actions) pages on GitHub Docs. Good luck! 👍

This hands on lab consists of the following steps:
- [Creating a repository](#creating-a-repository)
- [Creating the workflow](#creating-the-workflow)
- [Viewing your workflow results](#viewing-your-workflow-results)

## Creating a repository

Go to [Code](/../../) tab of this repository and click `Use this template`:

<img width="400" alt="2022-09-18_11-24-58" src="https://user-images.githubusercontent.com/5276337/190895393-6fa0fad9-e05c-4fea-8126-a291b087d663.png">

Select your GitHub user as the owner and name the repository. Leave the repo public to have unlimited action minutes:

<img width="400" alt="2022-09-18_11-25-57" src="https://user-images.githubusercontent.com/5276337/190895398-751a1ec9-c1cf-497f-beb7-a6b53d4d911e.png">

Continue now in the new repository.

## Creating the workflow

Go to **Actions** | [New Workflow](/../../actions/new) and click on [set up a workflow yourself](/../../new/main?filename=.github%2Fworkflows%2Fmain.yml&workflow_template=blank).

1. Rename the file `main.yml` in the `.github/workflows` directory to `github-actions-demo.yml`.
<img width="400" alt="image" src="https://user-images.githubusercontent.com/5276337/174096754-4e2d7219-9caf-42e8-bfd9-c190762886d3.png">

2. Remove the template content - we want to create the workflow from scratch.
3. Click <kbd>Ctrl</kbd>+<kbd>Space</kbd> and select name as the first element:

<img width="400" alt="image" src="https://user-images.githubusercontent.com/5276337/174097468-8be92e37-7948-4895-b5ed-20a22c5773bc.png">

4. Set the workflow name to `GitHub Actions Demo`:

```YAML
name: GitHub Actions Demo
```
5. Add the triggers to the worklow with the help of <kbd>Ctrl</kbd>+<kbd>Space</kbd> and the documentation. We want the workflow to trigger:
- on every push to the `main` branch, but not when there are changes to files in the `.github` folder.
- on every pull request with `main` as the base branch
- Every sunday at 6:15 UTC
- Manually

<details>
<summary>Solution</summary>

```YAML
on:
push:
branches: [ main ]
paths-ignore: [.github/**]
pull_request:
branches: [ main ]
schedule:
- cron: '15 6 * * 0'
workflow_dispatch:
```

</details>

6. Create a job `Build` that runs on the latest Ubuntu image on GitHub hosted runners. Check the documentation of the [virtual environments](https://github.com/actions/virtual-environments/) what label to use and what version it is. The job should do the following things:
- Output the name of the event that triggered the workflow
- Output the name of the branch that the repository is currently referencing
- List all files in the repository

<details>
<summary>Solution</summary>

```YAML
jobs:
Build:
runs-on: ubuntu-latest
steps:
- run: |
echo "🎉 The job was triggered by event: ${{ github.event_name }}"
echo "🔎 The name of your branch is ${{ github.ref }} and your repository is ."
- uses: actions/checkout@v3.3.0
- name: List files in the repository
run: |
echo "The repository ${{ github.repository }} contains the following files:"
tree
```

</details>

7. Commit the workflow file - and trigger the workflow manually. It should not run automatically if your path filter works. Got to [Action](/../../Actions), select [GitHub Actions Demo](/../../actions/workflows/github-actions-demo.yml) and `Run workflow`:

## Viewing your workflow results

1. Click on your workflow run:

<img width="600" alt="image" src="https://user-images.githubusercontent.com/5276337/174105747-0e205e0d-37cc-464c-905b-5b29be74fc75.png">

2. Click on the job 'Build':

<img width="400" alt="image" src="https://user-images.githubusercontent.com/5276337/174105990-a1c204c6-fb7d-44a4-9343-6982899edb25.png">

3. Expand `Set up job` and note the log with the line number (line numbers are links). Check the information about the virtual environment and included software:

<img width="600" alt="image" src="https://user-images.githubusercontent.com/5276337/174106759-c2a8f933-74cf-42a4-899b-b29dc67eccd7.png">

4. Expand your jobs and check that the output was correct.

<img width="400" alt="image" src="https://user-images.githubusercontent.com/5276337/174107136-af9187c1-dbee-4109-9ddc-f2abd4830282.png">

5. Verify you other triggers by modifying the [README.md](/README.md) file:
- Modify and commit: triggers build (`push`)
- Modify and add `[skip ci]` (not triggering the workflow):
<img width="350" alt="image" src="https://user-images.githubusercontent.com/5276337/174110845-93d4a38a-9c8a-4336-9b6a-9089ea9a1cfd.png">

- Modify and create pull request (trigger: `pull_request`)

## Summary

In this hands-on you've learned to create you first workflow with triggers, jobs, steps, and expressions. Next you will write your [first GitHub Action](02-My-first-action.md).
