⁠🛠️ Building Locally

Clone the project and build the image using the provided Dockerfile:

git clone https://github.com/Mgldvd-Docker/alpine-php85.git

cd alpine-php85

docker build -t mgldvd/alpine-php85:local .

Run the container to verify the build:

docker run --rm -it -v "$PWD:/app" mgldvd/alpine-php85:local bash

⁠🐳 Docker Compose

Use the bundled compose.yml⁠ to launch an interactive shell with your local app/ directory mounted into the container:

mkdir app

wget https://raw.githubusercontent.com/Mgldvd-Docker/alpine-php85/refs/heads/master/compose.yml

or create file: compose.yml

services:
    app:
        image: mgldvd/alpine-php85
        command: bash
        volumes:
            - ./app:/app
        stdin_open: true
        tty: true
        restart: "no"

docker compose run --rm app

To keep the container running in the background instead, start it detached and exec into it when needed:

docker compose up -d
docker compose exec app bash

⁠🚀 Publishing Workflow

The GitHub Actions workflow at .github/workflows/docker-publish.yml automates image publication. It performs the following steps:

1. Checks out the repository.
2. Prepares Docker Buildx for multi-platform builds.
3. Authenticates against Docker Hub using repository secrets.
4. Generates OCI metadata, including links back to GitHub and Docker Hub.
5. Builds the image and pushes the multi-arch latest tag.

⁠🔐 Required Secrets

Add the following secrets in the GitHub repository settings before running the workflow:

• DOCKERHUB_USERNAME: Docker Hub account name (e.g., mgldvd).
• DOCKERHUB_TOKEN: Docker Hub access token with permission to push the repository.

⁠▶️ Triggering a Publish

Push commits to the deploy/hub branch or run the workflow manually from the GitHub Actions tab to build and publish a new image version.
