Create a new package pkg/apis/nfd/v1alpha1 and migrate the custom rule
expressions over there. This is the first step in creating a new CRD API
for custom rules.
Implement a framework for more flexible rule configuration and matching,
mimicking the MatchExpressions pattern from K8s nodeselector.
The basic building block is MatchExpression which contains an operator
and a list of values. The operator specifies that "function" that is
applied when evaluating a given input agains the list of values.
Available operators are:
- MatchIn
- MatchNotIn
- MatchInRegexp
- MatchExists
- MatchDoesNotExist
- MatchGt
- MatchLt
- MatchIsTrue
- MatchIsFalse
Another building block of the framework is MatchExpressionSet which is a
map of string-MatchExpression pairs. It is a helper for specifying
multiple expressions that can be matched against a set of set of
features.
This patch converts all existing custom rules to utilize the new
expression-based framework.
Separate feature discovery and creation of feature labels in the pci
source.
Move pci_utils from source/internal to the source/pci package. Change
the implementation of the PciID custom rule to utilize the FeatureSource
interface of the pci source.
Also, add minimalist unit test.
- Implement the 'custom' feature source utilizing the
match rules implemented in previous commit.
- Add a static custom feature list for:
1. rdma.capable - marks a node where devices that support
RDMA are present.
2. rdma.enabled - marks a node where rdma modules have
been loaded.
A user may extend these features with additional match rules via
NFD configuration file.
- Add a Rule interface to help describe the contract
between a match rule and the Custom source that uses it.
- Add PciIdRule - a rule that matches on the PCI attributes:
class, vendor, device. Each is provided as a list of elements(strings).
Match operation: OR will be performed per element and AND will be
performed per attribute.
An empty attribute will not be included in the matching process.
Example:
{
"class": ["0200"]
"vendor": ["15b3"]
"device": ["1014", "1016"]
}
- Add LoadedKmodRule - a rule that matches a list of kernel
modules with the kernel modules currently loaded in the node.
Example:
{
["rdma_cm", "ib_core"]
}
