The build-img script can generate images for a particular distro based on only one Dockerfile.

The docker/ directory contains all the script needed to use when building images.

Please take a look to the Makefile for configuration options.

make, make all and make build will build the docker images locally. If no TAG variable is specified, then only the images with the form ORG/IMG:DIST-vX will be generated, as well as the ORG/IMG which will only be tagged for the LATEST_DIST distribution.

If make build TAG=v2.0.1 is used (for example), the image ORG/IMG:DIST-v2.0.1 will be tagged too.

If a TAG is specified but is a pre-release (as per SemVer, i.e. it contains a -), the default tagged image will be ORG/IMG:DIST-vX-test (instead of ORG/IMG:DIST-vX) and ORG/IMG will not be tagged at all.

make push will push all the images that would be generated by make build (same rules apply for TAG).

As part of base image generation, user named cachalot will be created. It is intended to be used to run tests without accidental root access which may affect the result.

This user is added to sudoers with a permission to run any sudo command without a password. This is primarily to be able to install new packages as part of the testing script - when such root access is not necessary, it is recommended to use host user ID instead.
