This patch enables automatic pushes of release images whenever a new git
tag is created. This works as expected as the $TRAVIS_BRANCH variable is
set to $TRAVIS_TAG when builds are triggered by a new tag.
Configure .travis.yml to automatically push builds on the master branch
to the container image registry (quay.io by default). This will
automatically make the latest "experimental" version of NFD, built from
the tip of the master branch, available in the upstream Docker
repository.
IMAGE_REPO_USER and IMAGE_REPO_PASSWORD environment variables must be
defined in the travis repositorys settings in order for the deployment
step to be triggered.
This reduces the size of the Docker image from ca. 1.2GB down to about
750MB.
Also, move unit tests from .travis.yml to Dockerfile. Final production
image is not able to run unit tests anymore, as sources are missing from
there.
- Added git version to published labels.
- Minor formatting fix in job template.
- Added .travis.yml and added build status image link to README.
- Added .gitignore.
