⁠SquareOne Docker Images

Base docker images for SquareOne projects. View it on DockerHub⁠.

⁠PHP

Image Name: moderntribe/squareone-php

⁠Supported Tags

• latest: The latest Dockerfile version using the most recent PHP version (currently 8.0), built from the master branch.
• 80-latest: The latest Dockerfile version for PHP 8.0, built from the master branch.
• 80-<x.y.z> or 80-<x.y>: Specific Dockerfile versions for PHP 8.0, built based on matching tags.
• 74-latest: The latest Dockerfile version for PHP 7.4, built from the master branch.
• 74-<x.y.z> or 74-<x.y>: Specific Dockerfile versions for PHP 7.4, built based on matching tags.
• We recommend you use the minor version, so you can continue to receive updates when doing a docker pull, e.g. moderntribe/squareone-php:80-1.0 moderntribe/squareone-php:74-2.1

⁠Adding New Versions

• Create a directory for the new version, e.g., /php/8.1/

• Create the Dockerfile and any supporting files in that directory.

• Add automated build configurations to Docker Hub moderntribe/squareone-php for the PHP version. Here is an example of the build rules to create version 8.0:

  Source Type	Source	Docker Tag	Dockerfile location	Build Context
  Branch	master	80-latest	Dockerfile	/php/8.0/
  Tag	/^php80-([0-9.]+)$/	80-{\1}	Dockerfile	/php/8.0/

⁠Testing Releases Before Tagging

After you've made changes to a Dockerfile, it should be built locally and tested before being released.

• Update the php extension installer image: docker pull mlocati/php-extension-installer
• cd into the folder of the Dockerfile that was modified
• Build and tag the image with a custom name: docker build -t moderntribe/squareone-php:$version-test ., e.g. docker build -t moderntribe/squareone-php:74-3.0.6-test .
• Test it in the square-one framework⁠ by temporarily editing dev/docker/docker-compose.yml⁠ and updating the x-php image.

x-php: &php
  # Original image
  # image: moderntribe/squareone-php:74-3.0
  # Test image
  image: moderntribe/squareone-php:74-3.0.6-test

• Run so start and validate the project successfully loads.

⁠Tagging Releases

• Commit and push the update to the repo. This should trigger an automatic build on the master branch for the *-latest tags.
• Tag the version, prefixed with the affected PHP version, suffixed with the release version. E.g., php80-1.0.0 for the first release of a build for PHP 8.0.
• Tags should follow semantic versioning: php<version>-<major>.<minor>.<patch>. <major> versions introduce breaking changes. <minor> versions add features and fix bugs. <patch> versions fix bugs.

⁠Downstream entrypoint scripts

When using an image from this repo in the downstream, you can add custom scripts in the docker-entrypoint.d folder.

All scripts in there will be copied over and automatically executed with run-parts⁠

Keep in mind the limitations of naming these scripts, they must consist entirely of ASCII upper- and lower-case letters, ASCII digits, ASCII underscores, and ASCII minus-hyphens. So no .sh extensions.
