# This script holds docker related functions.
|
|
# You can set the platform to build with BUILD_PLATFORMS, with format: `<os>/<arch>`
|
|
# When `OUTPUT_TYPE=docker` is set, `BUILD_PLATFORMS` cannot be set with multi platforms.
|
|
# See: https://github.com/docker/buildx/issues/59
|
|
#
|
|
# Usage:
|
|
# hack/docker.sh <target>
|
|
# Args:
|
|
# $1: target to build
|
|
# Environments:
|
|
# BUILD_PLATFORMS: platforms to build. You can set one or more platforms separated by comma.
|
|
# e.g.: linux/amd64,linux/arm64
|
|
# OUTPUT_TYPE Destination to save image(`docker`/`registry`/`local,dest=path`, default is `docker`).
|
|
# REGISTRY image registry
|
|
# VERSION image version
|
|
# DOCKER_BUILD_ARGS additional arguments to the docker build command
|
|
# SIGN_IMAGE enabled sign image with cosign, disabled by default.
|
|
# Examples:
|
|
# hack/docker.sh karmada-aggregated-apiserver
|
|
# BUILD_PLATFORMS=linux/amd64 hack/docker.sh karmada-aggregated-apiserver
|
|
# OUTPUT_TYPE=registry BUILD_PLATFORMS=linux/amd64,linux/arm64 hack/docker.sh karmada-aggregated-apiserver
|
|
# DOCKER_BUILD_ARGS="--build-arg https_proxy=${https_proxy}" hack/docker.sh karmada-aggregated-apiserver"
|
|
# SIGN_IMAGE="1"
