Additional notes about multi-arch images

This feature was added on 21th April 2022.

• Newer vesions from now on (v7.3.7+) will be multi-arch images (--platform linux/amd64,linux/arm/v7,linux/arm64/v8,linux/arm/v6,linux/ppc64le,linux/s390x)

1. I don't support other architectures, except amd64, because I have no other environment to check. If you have any issues with other arch, you need raise PR to fix it.
2. There would be no difference for docker pull , docker run command with other arch, you can run it as normal. For example, if you need pull image from arm (such as new Mac M1 chip), you can run docker pull alpine/semver to get the image directly.

Usage

RELEASE_TYPE ?= patch

CURRENT_VERSION := $(shell git ls-remote --tags | awk '{ print $$2}'| sort -nr | head -n1|sed 's/refs\/tags\///g')

ifndef CURRENT_VERSION
  CURRENT_VERSION := 0.0.0
endif

NEXT_VERSION := $(shell docker run --rm alpine/semver semver -c -i $(RELEASE_TYPE) $(CURRENT_VERSION))

current-version:
	@echo $(CURRENT_VERSION)

next-version:
	@echo $(NEXT_VERSION)
