Rules engine for NetworkInterface.
InstanceNetworkInterfaceRuleBook(rule_defs=None)[source]¶Bases: google.cloud.forseti.scanner.audit.base_rules_engine.BaseRuleBook
The RuleBook for enforced networks resources.
_abc_cache = <_weakrefset.WeakSet object>¶_abc_negative_cache = <_weakrefset.WeakSet object>¶_abc_negative_cache_version = 214¶_abc_registry = <_weakrefset.WeakSet object>¶add_rule(rule_def, rule_index)[source]¶Add a rule to the rule book.
Add a rule to the rule book.
The rule supplied to this method is the dictionary parsed from the rules definition file.
For example, this rule…
rules:
name: all networks covered in whitelist project: ‘*’ network: ‘*’ is_external_network: True whitelist:
- master:
- master-1
- network:
- network-1
- network-2
- default:
- default-1
… gets parsed into: {
- “rules”: [
- {
“name”: “all networks covered in whitelist”, “project”: “*”, “network”: “*”, “is_external_network”: true, “whitelist”: {
- “master”: [
- “master-1”
], “network”: [
“network-1”, “network-2”], “default”: [
“default-1”]
}
}
]
}

build_rule_book(global_configs=None)[source]¶Build InstanceNetworkInterfaceRuleBook from rules definition file.
| Parameters: | global_configs (dict) – Global Configs |
|---|
find_violations(instance_network_interface, force_rebuild=False)[source]¶Determine whether the networks violates rules.
| Parameters: |

| Return type: | list |
Rule(rule_name, rule_index, rules)[source]¶Bases: object
The rules class for instance_network_interface.
RuleViolation(resource_type, resource_id, full_name, rule_name, rule_index, violation_type, project, network, ip, resource_data, resource_name)¶Bases: tuple
__getnewargs__()¶Return self as a plain tuple. Used by copy and pickle.
__new__(_cls, resource_type, resource_id, full_name, rule_name, rule_index, violation_type, project, network, ip, resource_data, resource_name)¶Create new instance of RuleViolation(resource_type, resource_id, full_name, rule_name, rule_index, violation_type, project, network, ip, resource_data, resource_name)
__repr__()¶Return a nicely formatted representation string
_asdict()¶Return a new OrderedDict which maps field names to their values.
_fields = ('resource_type', 'resource_id', 'full_name', 'rule_name', 'rule_index', 'violation_type', 'project', 'network', 'ip', 'resource_data', 'resource_name')¶_make(iterable, new=<built-in method __new__ of type object>, len=<built-in function len>)¶Make a new RuleViolation object from a sequence or iterable
_replace(**kwds)¶Return a new RuleViolation object replacing specified fields with new values
