This repository is aimed to be added as git submodule into particular containers' source repositories. By default, the path to submodule should be named 'common'.
This section explains the usage of the shared scripts in this repository when it is used as a submodule in a container source repository.
Once you have the repository set as a submodule include common.mk into your
root Makefile in order to access the default rules used to call shared scripts.
Default rules:
make or make build
This rule will build an image without tagging it with any tags after it is built.
After the image finishes building the scripts will squash the image using docker-squash.
make build will also expect a README.md so that it can transfrom it into
a man page that gets added to the image so make sure it is available and that
you have the go-md2man tool installed on your host.
make tag
Use this rule if you want to tag an image after it is built. It will be tagged with
two tags - name:latest and name:version.
Depends on build
make test or make check
This rule will run the testsuite scripts contained in the container source repositories.
It expects the test to be available at $gitroot/$version/test/run
Depends on tag as some tests might need to have the images tagged (s2i).
make test-openshift
Similar to make test but runs testsuite for Openshift, expected to be found at
$gitroot/$version/test/run-openshift
make test-with-conu
The rule is similar to make test. It runs a test suite written using conu
library. The path to the test script is
meant to be at $gitroot/$version/test/run-conu. By default the test suite is
being run in the current environment. You can also run the tests in a container
by defining variable CONU_IMAGE. Container images with conu are available in
this docker hub repository, a good value for
the variable is docker.io/usercont/conu:0.6.2.
make clean
Runs scripts that clean-up the working dir. Depends on the clean-images rule by default
and additional clean rules can be provided through the clean-hook variable.
make clean-images
Best-effort to remove the last set of images that have been built using the scripts.
There are additional variables that you can use that the default rules are prepared to work with:
VERSIONS
Names of the directories in which the Dockerfiles are contained. Needs to be defined in your
Dockerfile for the scripts to know which versions to build.
OS
OS version you want to build the images for. Currently the scripts are able to build for
centos (default), centos6, rhel7 and fedora.
SKIP_SQUASH
When set to 1 the build script will skip the squash phase of the build.
CUSTOM_REPO
Set this variable to the path to your local .repo files you want to have available inside
the image while building. Useful for building rhel-based images on an unsubscribed box.
Be aware that you cannot write to any .repo files used this way inside the image as they
will be mounted into the image as read-only.
UPDATE_BASE
Set to 1 if you want the build script to always pull the base image when available.
DOCKER_BUILD_CONTEXT
Use this variable in case you want to have a different context for your builds. By default
the context of the build is the versioned directory the Dockerfiles are contained in.
clean-hook
Append Makefile rules to this variable to make sure additional cleaning actions are run
when make clean is called.
Just run make check
