github action runner showing "idle" and not updating the main website - github

Question

I have been using DigitalOcean: if I change or commit repository the website not being updated.
I am using just one master branch, I had 23 file changes but on the site no effects.
here is my action code:
name: Node.js CI
on:
push:
branches: [ master ]
jobs:
build:
runs-on: self-hosted
strategy:
matrix:
node-version: [14.x]
# See supported Node.js release schedule at https://nodejs.org/en/about/releases/
steps:
- uses: actions/checkout#v2
- name: Use Node.js ${{ matrix.node-version }}
uses: actions/setup-node#v2
with:
node-version: ${{ matrix.node-version }}
cache: 'npm'
- run: npm i
- run: npm run build --if-present
- run: npm test

Answer 1

if I change or commit repository the website not being updated.
I am using just one master branch,
First, a change or commits are local actions: you need to push (git push) to GitHub in order for any action to have a chance to run.
Second, assuming that you have pushed, but your workflow was not triggered, add a on: directive (that you have) and double-check your default branch: recent repositories are using main, not master.
You can see an example in the official GitHub documentation "Building and testing Node.js / Starting with the Node.js workflow template":
name: Node.js CI
on:
push:
branches: [ main ]
pull_request:
branches: [ main ]
jobs:
build:
runs-on: ubuntu-latest
strategy:
matrix:
node-version: [10.x, 12.x, 14.x, 15.x]
steps:
- uses: actions/checkout#v2
- name: Use Node.js ${{ matrix.node-version }}
uses: actions/setup-node#v2
with:
node-version: ${{ matrix.node-version }}
- run: npm ci
- run: npm run build --if-present
- run: npm test
Third, if you need to see some effect on a DigitalOcean Droplet, you might need to use digitalocean/action-doctl, in order to deploy (to DigitalOcean) what your GitHub action has build on GitHub side.
