# Release tools #

This directory contains tools for Kata Containers releases.

## tag_repos.sh ##

The `tag_repos.sh` script is used to create tags for the Kata Containers
repositories. This script make sure that all the repositories are in the
same version (by checking the VERSION file).

It will create an **annotated tag** for the new release version for the
following repositories:

- agent.
- proxy.
- runtime.
- shim.
- throttle.

Additionally, the script will tag tests and osbuilder repositories to know
the version used to create an image or tests used for Kata release.
