Hello Viwers, I am back again with another blog and the topic name is Github Actions CI CD Pipelines WorkFlows. So in this blog we will consider so many thing about CI/CD pipelines workflows like what is Github Actions, how to use - step by step, can i used github actions for CI/CD, A demo workflows file - How to create, run and check results, Terms: Workflows, Events, Jobs, Steps.

Can i used github actions for CI/CD?

Yes, GitHub Actions is commonly used for Continuous Integration (CI) and Continuous Deployment (CD) workflows.

What is Github Actions?

GitHub Actions is an automation platform provided by GitHub that allows you to set up workflows for your software development projects. It enables you to automate various tasks, such as building, testing, and deploying your code directly from your GitHub repository.

Key features of GitHub Actions include:

- Automate SDLC workflows

- Implement CI CD DevOps

Demo

Let's start with the demo how to use github action. Actually you don't got anywhere for using CI/CD, you can use all features in GitHub Action.

Step 1 - Signup and Login to GitHub.com 

Step 2 - Create a new Repository

 Go to this  + Plus button dropdown. Click on new repository.

 Now i will called as github-actions and set as public and click on create repository button (when go to scroll down on same page).

 Step 3 - In the repo create a folder .github/workflows

 here you can either create manually and then commited push to the repository. or you can go to this action tab.

 here you can see the github actions and you can also use templates or use workflows yourself but we will go to setup workflows as yourself.

Step 4 - In the folder create a YAML file with .yml extension

Here this will automatically create .github/workflows folder  and the name of main.yml file but this is empty code. yaml is programming language and .yml this is a file format but particular syntax.

Step 5 - Add the content of the workflow in the file

Now content adding time..

Go to this link and copy the syntax of printing of hello world and you can also use online yaml formater online as a precautions of indentation error.

Hello World - CLICK HERE

YAML Formatter - CLICK HERE

name: hello-world
'on': push
jobs:
  my-job:
    runs-on: ubuntu-latest
    steps:
      - name: my-step
        run: echo "Hello World!"

Certainly! The YAML code you've provided is a simple GitHub Actions workflow. Let's break down each part:

```yaml
name: hello-world
```

This sets the name of your workflow. In this case, it's named "hello-world." This name is just for your reference and doesn't affect the functionality of the workflow.

```yaml
on: push
```

This specifies the event that triggers the workflow. In this case, the workflow will be triggered whenever there is a `push` event to the repository.

```yaml
jobs:
  my-job:
    runs-on: ubuntu-latest
    steps:
```

Here, you define a job named "my-job" that runs on an `ubuntu-latest` virtual machine. This means the steps within this job will be executed on a machine with the latest version of Ubuntu.

```yaml
  - name: my-step
    run: echo "Hello World!"
```

Within the job, you define a step named "my-step." This step uses the `run` key to specify the command that should be executed. In this case, it's a simple command to echo "Hello World!" to the console.

So, when a `push` event occurs in your repository, GitHub Actions will execute this workflow. The workflow consists of one job named "my-job," which runs on an Ubuntu machine. In that job, there's a single step named "my-step" that echoes "Hello World!" to the console.

This is a basic example, and GitHub Actions can be extended to perform more complex workflows, such as running tests, building and deploying applications, and more, depending on the needs of your project.

Step 6 - Commit and push the changes

This should start with github actions workflows.

Step 7 - Go to Repo main page and click "ACTIONS TAB" 

So this is our workflow

Step 8 - Select the workflow from left sidebar and check the logs

Here is the single job ( i have only one thats why)  When we click on this job, here we can see the logs. Here we have a job. 

# First it is setup that will the spin up ubuntu system, as you can see, it is running the ubuntu image (operating system).

# Second this is the actual job. By step here it is running, this comment "echo hello world" which is printing hello world. 

# Third one is completing the job, doing all the cleanup process.

So, This is how it is running ...ummm looking good LOL ;-)

Also if you want to re-run this job, you can also click on it.

You can also check all types of detals like Usage, Workflow file.

Don't forget to explore more things and forget to share....
