In this section, we will see how to push code with GitHub actions.

We will create a file named example.txt and add some content in it and push it to a new branch that you provide in the workflow.

action-demo/.github/workflows/code_push.yml

on:
  push:
    branches:
      - master

name: Create and push file
jobs:
  create-and-push-file:
    name: Create and push file
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@master
    - name: Create and push file
      uses: './'
      env:
        USER_NAME: example
        USER_EMAIL: example@nouser.(none)
        BRANCH_NAME: code-push-example
        COMMIT_MESSAGE: "Action add file"

Here USER_NAME and USER_EMAIL will be the actor who will push the code in the new branch.

action-demo/entrypoint.sh

#!/bin/bash

# Install git
# Ubuntu container by default do not have git installed.
apt update && apt install git -y

# Add git config
git config --global user.name "$USER_NAME"
git config --global user.email "$USER_EMAIL"

cd $GITHUB_WORKSPACE

# Create example.txt  
touch "example.txt"

# Put some content in example.txt
echo "You are doing awesome !" > example.txt

# Checkout branch name based on Variable provided in workflow
git checkout -b $BRANCH_NAME

# Stage files and changes
git add .

# Commit message
git commit -m "$COMMIT_MESSAGE"

# Push the code
git push origin $BRANCH_NAME

Push the code and when the action completes you will see the results.

You can save more time in the action by creating a custom Docker Image for the action. By applying this you will reduce a step where docker image will be built by action. Don’t worry if you did not understand this, you will learn this by creating more and more time-consuming processes.
