Dockerfile.ppc64le 알아보기

ppc64le/ubuntu 환경에서 원하는 버전의 Docker engine 을 사용하기 위해서, 직접 Docker 소스코드를 빌드하여 사용하는 방법이 있습니다.

이때 사용하게 되는 것이 Docker github에 이미 올라와 있는, 잘 만들어진 Dockerfile.ppc64le 입니다. 이 파일을 살펴보면, go lang, 등등의 버전을 원하는 대로 설정하여 Docker 엔진을 빌드하여 사용할 수 있습니다.

아래는 Dockerfile.ppc64le 내용입니다.


# This file describes the standard way to build Docker on ppc64le, using docker
#
# Usage:
#
# # Assemble the full dev environment. This is slow the first time.
# docker build -t docker -f Dockerfile.ppc64le .
#
# # Mount your source in an interactive container for quick testing:
# docker run -v `pwd`:/go/src/github.com/docker/docker --privileged -i -t docker bash
#
# # Run the test suite:
# docker run --privileged docker hack/make.sh test-unit test-integration-cli test-docker-py
#
# Note: AppArmor used to mess with privileged mode, but this is no longer
# the case. Therefore, you don't have to disable it anymore.
