EduceLab Docker CI Configuration

This repository contains the Dockerfile to build the ghcr.io/educelab/ci-docker Docker image. This image contains all prerequisite libraries required to build and test the volume-cartographer project. Most of the build is handled by vc-deps so that consistency can be maintained across platforms.

Requirements

• Docker engine 19.03+

Building

1. Get the source code for the repository:

    git clone --recursive https://github.com/educelab/ci-docker
    cd ci-docker

2. Update the version number, packages, and code references. See Updating the version.

3. If your changes don't affect the base image, pull the latest base image from the registry to avoid rebuilding it:

   docker pull ghcr.io/educelab/ci-docker:base.latest

4. Set up a multi-arch Docker builder and run the build script:

   docker buildx create --use
   ./build.sh

Updating the version

Change the version components in build.sh. Values should match the rules for semantic versioning:

# build.sh
VER_MAJOR=12
VER_MINOR=0
VER_PATCH=0

Version rules

Updating the Debian version

• Set VER_MAJOR to the Debian version number
• Set VER_MINOR=0
• Set VER_PATCH=0

Adding/removing apt packages

• Increment VER_MINOR
• Set VER_PATCH=0

Updating the apt packages (i.e. rebuilding without adding/removing packages)

• Remove your local copy of ci-docker:base.latest
• Increment VER_PATCH

Updating the installed Qt version

• Increment VER_MINOR
• Set VER_PATCH=0

Updating vc-deps to a new minor version

• Checkout the appropriate ref in the vc-deps directory
• Increment VER_MINOR
• Set VER_PATCH=0

Updating vc-deps to a new patch version

• Checkout the appropriate ref in the vc-deps directory
• Increment VER_PATCH
