- v0.x: Reusable Makefile for Travis CI and Docker builds.
- v1.x: GitHub Actions and Docker build experiments.
include container.mk inside Makefile after providing some variables:
REPO_LOCAL=localhost/awesome-project
REPO_PUBLIC=quay.io/my-user/awesome-project
DOCKER_HUB=quay.io
DOCKER_ROOTFS=rootfs
include container.mk
Where:
REPO_LOCAL: URL used by Docker to create local imagesREPO_PUBLIC: URL used by Docker to push images when running on Travis CIDOCKER_HUB: Where to login before push a new imageDOCKER_ROOTFS: Optional, root directory of Dockerfile, defaults torootfs
Provide as Travis CI environment variables:
DOCKER_USR: Username - tip: use a robot accountDOCKER_PWD: Password of this user
After include container.mk Makefile will have these new variables:
GIT_COMMIT: Short git commit of this build:git-xxxxxxxREPOandTAG: REPO url and TAG name used to build and push image
container.mk add the following targets to Makefile:
image: Build a new Docker imagepush: Push a Docker image to a image repositorytag-push: Push o 5DBB nly if Travis CI tells that this build has a tag and is not a pull request
Typing just make will run the first declared target, which is the default target of the Makefile.
The following fragment declares my-build as the default target, declaring it as a dependency of the real default. This way my-build will behave like a default target and will have access to variables declared in container.mk.
.PHONY: default
default: my-build
REPO_LOCAL=localhost/beagle
REPO_PUBLIC=quay.io/jcmoraisjr/beagle
DOCKER_HUB=quay.io
include container.mk
.PHONY: my-build
my-build:
...
There is also .DEFAULT_GOAL but it isn't provided on make <= 3.80.
