release-tag.sh

#!/bin/bash

# Script helps to create git tags for releases/hotpatches.
# Requires semver utility to be installed (go install github.com/maykonlf/semver-cli/cmd/semver@v1.1.0)

# The service argument (--service or -s) is the only required argument and should be
# a valid service name from the /services folder with the .semver.yaml file.
# A tag is created based on the service name and its version from the .semver.yaml.

# By default the tag is created and pushed to the remote. You can change this behaviour by
# providing the (--skip-push) flag. It is not recommended to use --skip-push flag
# for normal flows. Use it only in special cases and for debug/test scenarios.


# Example:
# sh scripts/release-tag.sh --service myservice [--skip-push]
