This is the first G3v4 release, introducing the updated startup scripts. The previous version G3v3 will still be available in this repository as the branch archived-generation-g3v3.

• The updated startup scripts that support overriding the user ID (id) and group ID (gid) without needing the former build argument ARG_FEATURES_USER_GROUP_OVERRIDE, which has been removed.
• The user ID and the group ID can be overridden during the build time (docker build) and the run time (docker run).
• The user name, the group name and the initial sudo password can be overridden during the build time.
• The permissions of the files /etc/passwd and /etc/groups are set to the standard 644 after creating the user.
• The content of the home folder and the startup folder belongs to the created user.
• The created user gets permissions to use sudo. The initial sudo password is configurable during the build time using the build argument ARG_SUDO_INITIAL_PW. The password can be changed inside the container.
• The default id:gid has been changed from 1001:0 to 1000:1000.

Changes in build arguments:

• removed ARG_FEATURES_USER_GROUP_OVERRIDE and ARG_HOME_OWNER
• renamed ARG_SUDO_PW to ARG_SUDO_INITIAL_PW

Release 22.11

Release 22.11

This is a milestone release. It's the first release of the new building pipeline version G3v2. The previous version G3v1 will still be available in this repository as the branch archived-generation-g3v1.

The version G3v2 brings the following major changes:

• Significantly improved building performance by introducing a local cache (g3-cache).
• Auto-building on the Docker Hub and using of the GitHub Actions have been abandoned.
• The enhanced building pipeline moves towards building the images outside the Docker Hub and aims to support also stages with CI/CD capabilities (e.g. GitLab).
• The local stage is the default building stage. The new building pipeline has already been tested also with a local GitLab installation in a Docker container on a Linux machine.
• Automatic publishing of README files to the Docker Hub has been removed, because it hasn't work properly any more. However, the README files can be still prepared with the provided utility and then copy-and-pasted to the Docker Hub manually.

Added files:

• docker/hooks/cache
• ci-builder.sh
• readme-builder.md
• readme-ci-builder.md
• readme-g3-cache.md
• readme-local-building-example.md
• utils/readme-util-readme-examples.md

Removed files:

• local-builder-readme.md
• local-building-example.md
• utils/example-secrets-utils.rc
• utils/examples-util-readme.md
• .github/workflows/dockerhub-autobuild.yml
• .github/workflows/dockerhub-post-push.yml
• .github/workflows/deploy-readme.sh

Many other files have been updated, some of them significantly.

Hoverer, the changes affect only the building pipeline, not the Docker images themselves. The Dockerfile, apart from using the new local g3-cache, stays conceptually unchanged.
