Hello, are you wondering if you can execute an Ansible Playbook with a Github action, then please continue reading.
In the particular case I needed to build a Docker image and push it on Dockerhub and after that manipulate the Docker Compose Manifest in order to update the service of the Stacks running in Swarm Mode.
So, Let's Dive In...

workflow_dispatch:
inputs:
imageTag:

steps:
- name: Checkout
uses: actions/checkout@v3
- name: Login to Docker Hub
uses: docker/login-action@v2

- name: Prep Docker Image (Metadata)
id: meta
uses: docker/metadata-action@v4

tags: ${{ inputs.imageTag }} # Tag
- name: Build and push
uses: docker/build-push-action@v3
with:
