Identify the latest DD-DeCaF tag on a particular Docker image.
The package was designed to only depend on the standard library in order to not have
any fast moving dependencies. It depends on Python 3.7+ for fromisoformat date
parsing.
The main purpose of this package is to provide a command line interface (CLI) for
retrieving the latest of all of a Docker image's tags. The DD-DeCaF organization uses a
particular tag format in order to manage dependencies between Docker images. Take
dddecaf/wsgi-base:alpine_2020-04-28_24fe0a0 as an example, it consists of the base
tag alpine, the date when it was built, and the short hash of the git commit from
which the image was generated. The corresponding "latest" image is
dddecaf/wsgi-base:alpine, however, child images should depend on the explicit tag.
In order to manage this more easily, this package provides a script for retrieving the
correct information. Sometimes, multiple images exist for the same date which is why
the label for the exact build timestamp is required. The following command
tag-spy dddecaf/wsgi-base alpine dk.dtu.biosustain.wsgi-base.alpine.build.timestampmay result in something like
alpine_2020-04-28_24fe0a0For more information, also check out the help.
