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.
To cut the image size further, down to about 75MB. We use Debian
strecth-slim as the base for the production image as golang docker
images use stretch as their base.
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.
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
Counting nodes in Ready state was too fragile, matching
entries like:
Ready,SchedulingDisabled
NotReady
By requiring whitespace on both side, we accept only clean Ready.
* 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.
intel-cmt-cat repo is located in github/intel/ now,
update links accordingly, correcting also some
source file names pointed from files under rdt-discovery/.
Updated also ref. to intel-cmt-cat in Dockerfile.
No functional changes.
* 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 makes the build more deterministic. Previously, nfd just blindly
took the tip revision from intel-cmt-cat master branch which could brake
the build without any changes in nfd itself.
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
Without correct proxy settings propagated to docker build it is not possible to
build node-feature-discovery from behind a proxy server, e.g. in corporate
networks. This patch fixes the issue by exporting all http(s) proxy related
environment variables as build-time variables.
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
* Make rdt-discovery buildable outside hardcoded path
Do not assume that nfd sources always reside under hardcoded directory
"/go/src/github.com/kubernetes-incubator/node-feature-discovery/". This
makes it possible e.g. to build nfd locally outside the Docker
container.
* Do not hardcode the path for RDT helper binaries
Utilize the standard PATH env variable, instead.
* Format main,fake,network go source to improve GoReportCard
Order of import changed in main.go and network.go,
missing ending newline added in fake.go
* Fixed simple golint suggestions in multiple files
Mostly about missing or incomplete comments
currently, nfd framework can't be work on Arm64 platform.
Fix points:
1, removed rdt on Arm64 platform
2, optimized the code related to multi-arch

* 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
