Support yaml/json based config file for nfd. This commit does not add
any actual consumers for the config file, yet.
By default, nfd tries to read
/etc/kubernetes/node-feature-discovery/node-feature-discovery.conf.
This can be changed by specifying the --config command line flag.
Introduce a new scheme where features may have logical sub-components.
Rename sriov labels from the network source according to the new
pattern:
sriov -> sriov.capable
sriov-configured -> sriov.configured
Also, document this new labeling scheme in the README.

Convert resource templates from json to yaml
Yaml is easier and less error prone to modify by hand. It also allows
comments which can be especially useful in the templates.
Make it possible to specify an image build tool other than docker - a
limitation is that the build tool must be compatible with docker files,
of course. This makes it possible to build an NFD image without the
Docker daemon, for example.
The image build command is specified in a makefile variable and can be
overridden from command line, for example:
$ make IMAGE_BUILD_CMD="buildah bud"
Thanks: Zvonko Kosic for suggesting this
* Arrange feature sources alphabetically
Just a cosmetic change, but, a small readability improvement.
* Implement detection of IOMMU (#136)
Add a new feature source, i.e. 'iommu', which detects if an IOMMU is
present and enabled in the kernel. The new node label is
node.alpha.kubernetes-incubator.io/nfd-iommu-present
A "newbie style" deployment attempt was made on a recent
cluster, and some added notes in README and in label-nodes.sh
could help someone who just started with node-feature-discovery.
Correcting also description of label-nodes.sh which does not
deal with unlabeled nodes as was promised in README.
* Re-order imports in main.go alphabetically
* Refactor argument parsing
* Run nfd periodically in a loop by default
* Implement --sleep-interval command line option
* Add template for running nfd as a Kubernetes DaemonSet
This commit:
- enables node-feature-dicovery to advertise selinux status
on the node by adding a label.
- update the template to mount /sys into the container, this is
needed to know about the selinux status on the host
- adds selinux source for unit tests
This change adds feature source "storage".
Add label if any non-rotational block device is present in the node.
The label will be: nfd-storage-nonrotationaldisk=true
* Adding SR-IOV capability discovery to node-feature-discovery
* SR-IOV capability discovery in NFD : code update after PR review
- using hostnetwork instead of volume mount in file node-feature-discovery-job.json.template
- iterating through network interfaces that are "up" in sources.go
- inserting logs in sources.go
- change in feature source name from "netid" to "network" in sources.go, README.md and main.go
* Added code for labels sriov=true (sriov_totalvfs > 0) and sriov-configured=true (sriov_numvfs > 0)
* Code Refactored: Added Network package and network.go

Update published label prefix.
Fixes#27.
- Changed prefix from `node.alpha.intel.com/nfd` to
`node.alpha.kubernetes-incubator.io/nfd`
Adds RemoveLabels() to remove all labels from a node that contains the
supplied search string. Uses this to remove node-feature-discovery
labels prior to re-applying newly discovered labels.
This behavior applies to consecutive runs of node-feature-discovery and
whatever restrictions are placed on it. For example if a whitelist is
specified that changes the labels that are discovered, any labels that
do not match the whitelist will be removed. Adds a small note to the
readme to point out this fact.
Adds tests to main_test.go to test the behavior of AddLabels and
RemoveLabels.
