# A script to build and push the Docker image to a Gitea container registry.
# A script to build and push a Docker image with multiple tags to a Gitea container registry.
# It automatically creates a 'base' version tag (e.g., v0.1.1 from v0.1.1-2) and a 'latest' tag.
#
# Usage:
# export GITEA_REPO_URL="https://git.example.com/user/repo"
# ./scripts/deploy.sh <TAG>
# ./scripts/deploy.sh <SPECIFIC_TAG>
#
# Example:
# ./scripts/deploy.sh v1.0.1
# ./scripts/deploy.sh v0.1.1
