Scripts

bin/build builds docker images. It parses the VERSION file, which is of the form SHA1-REVISION, where sha1 is the 10-character sha1-prefix version of the livegrep repository, and REVISION is a version number of updates in this repository within a given release.
bin/update-version updates the VERSION file and also the version configuration in the kubernetes configuration. It is most commonly run with -b to bump the REVISION, or --sha to change the SHA field. If run with no arguments, it synchronizes kubernetes/*.yaml with VERSION.
