* Simplified dockerfile - Changed from alpine to python:slim - Removed some database libs (because we *connect* to a db, not host it) * - Add gettext as required package - Only create inventree user as part of production build (leave admin access for dev build) * Tweaks for tasks.py * Fix user permissions (drop to inventree user) * Drop to the 'inventree' user level as part of init.sh - As we have mounted volumes at 'run time' we need to ensure that the inventree user has correct permissions! - Ref: https://stackoverflow.com/questions/39397548/how-to-give-non-root-user-in-docker-container-access-to-a-volume-mounted-on-the * Adjust user setup - Only drop to non-root user as part of "production" build - Mounted external volumes make it tricky when in the dev build - Might want to revisit this later on * More dockerfile changes - reduce required system packages - * Add new docker github workflow * Print some more debug * GITHUB_BASE_REF * Add gnupg to base requirements * Improve debug output during testing * Refactoring updates for label printing API - Update weasyprint version to 55.0 - Generate labels as pdf files - Provide filename to label printing plugin - Additional unit testing - Improve extraction of some hidden debug data during TESTING - Fix a spelling mistake (notifaction -> notification) * Working on github action * More testing * Add requirement for pdf2image * Fix label printing plugin and update unit testing * Add required packages for CI * Move docker files to the top level directory - This allows us to build the production image directly from soure - Don't need to re-download the source code from github - Note: The docker install guide will need to be updated! * Fix for docker ci file * Print GIT SHA * Bake git information into the production image * Add some exta docstrings to dockerfile * Simplify version check script * Extract git commit info * Extract docker tag from check_version.py * Newline * More work on the docker workflow * Dockerfile fixes - Directory / path issues * Dockerfile fixes - Directory / path issues * Ignore certain steps on a pull request * Add poppler-utils to CI * Consolidate version check into existing CI file * Don't run docker workflow on pull request * Pass docker image tag through to the build Also check .j2k files * Add supervisord.conf example file back in * Remove --no-cache-dir option from pip install
