Docker container for use in project 1 - web application at Fontys Venlo

The container can be found at: https://hub.docker.com/r/sebivenlo/prj1-web

This docker container is based on the official php-apache container.

The base container is extended with a couple of extensions that might be needed during the project.

Variants

Two image variants are published from this repo. Both share the same PHP version, extensions, and upload_max_filesize / post_max_size so application code behaves identically in both.

Tag	Target	Use case
sebivenlo/prj1-web:<version>	dev	Devcontainer / local development. Ships git, gnupg, zip CLI, a non-root devuser for UID/GID remapping, and php.ini-development (errors visible inline).
sebivenlo/prj1-web:<version>-prod	prod	Deployments (e.g. the FontysVenlo developer platform). No dev tooling, no devuser, and php.ini-production (stack traces not shown in HTTP responses).

Build a specific target locally:

docker build --target prod -t prj1-web:prod .
docker build --target dev  -t prj1-web:dev  .

docker build . (no --target) builds dev, matching the previous single-stage behaviour.

Extensions:

• GD
• EXIF
• PDO
• PDO PostgreSQL
• ZIP

Releasing a new version

  3. Push the tag to GitHub: git push origin <tag>
