Overview

Package api implements the struct definitions used on the northbound client API.

In particular this includes:

-  The various resource types as exposed on the Northbound API.  The valid resource
   types are:
	-  BGPPeer
	-  HostEndpoint
	-  Policy
	-  Pool
	-  Profile
-  The client configuration

The resource structures include the JSON tags for each exposed field. These are standard go-lang tags that define the JSON format of the structures as used by calicoctl. The YAML format also used by calicoctl is directly mapped from the JSON.

}

Node contains the details of a node resource which contains the configuration for a Calico node instance running on a compute host.

In addition to creating a Node resource through calicoctl or the Calico API, the Calico node instance must also be running on the specific host and should be provided the same Name as that configured on the Node resource. Note that, by default, the Calico node instance uses the hostname of the compute host when it is not explicitly specified - in this case, the equivalent Node resource should be created using the same hostname as the Name of the Node resource.

Operations on the Node resources is expected to be required when adding a new host into a Calico network, and when removing a host from a Calico network, and occasionally to modify certain configuration. Care should be taken when operating on Node resources: deleting a Node resource will remove all Node specific data.

	// Orchestrator represents the orchestrator using this node.
	Orchestrator string `json:"orchestrator"`
}

OrchRef is used to correlate a Calico node to its corresponding representation in a given orchestrator

type Policy

type Policy struct {
	unversioned.TypeMetadata
	Metadata PolicyMetadata `json:"metadata,omitempty"`
	Spec     PolicySpec     `json:"spec,omitempty"`
}

Policy contains information about a security Policy resource. This contains a set of security rules to apply. Security policies allow a selector-based security model which can override the security profiles directly referenced by an endpoint.

Each policy must do one of the following:

 	- Match the packet and apply an “allow” action; this immediately accepts the packet, skipping
       all further policies and profiles. This is not recommended in general, because it prevents
       further policy from being executed.
	- Match the packet and apply a “deny” action; this drops the packet immediately, skipping all
       further policy and profiles.
	- Fail to match the packet; in which case the packet proceeds to the next policy. If there
	  are no more policies then the packet is dropped.

Calico implements the security policy for each endpoint individually and only the policies that have matching selectors are implemented. This ensures that the number of rules that actually need to be inserted into the kernel is proportional to the number of local endpoints rather than the total amount of policy.

type PolicySpec

type PolicySpec struct {
	// Order is an optional field that specifies the order in which the policy is applied.

	// policy will be applied last.  Policies with identical order will be applied in
	// alphanumerical order based on the Policy "Name".

	// The ordered set of egress rules.  Each rule contains a set of packet match criteria and
	// a corresponding action to apply.
	EgressRules []Rule `json:"egress,omitempty" validate:"omitempty,dive"`

	// The selector is an expression used to pick pick out the endpoints that the policy should
	// be applied to.
	//
	// Selector expressions follow this syntax:
	//
	// 	label == "string_literal"  ->  comparison, e.g. my_label == "foo bar"
	// 	label != "string_literal"   ->  not equal; also matches if label is not present
	// 	label in { "a", "b", "c", ... }  ->  true if the value of label X is one of "a", "b", "c"
	// 	label not in { "a", "b", "c", ... }  ->  true if the value of label X is not one of "a", "b", "c"
	// 	has(label_name)  -> True if that label is present
	// 	! expr -> negation of expr
	// 	expr && expr  -> Short-circuit and
	// 	expr || expr  -> Short-circuit or
	// 	( expr ) -> parens for grouping
	// 	all() or the empty selector -> matches all endpoints.
	//
	// Label names are allowed to contain alphanumerics, -, _ and /. String literals are more permissive
	// but they do not support escape characters.
	//
	// Examples (with made-up labels):
	//
	// 	type == "webserver" && deployment == "prod"
	// 	type in {"frontend", "backend"}
	// 	deployment != "dev"
	// 	! has(label_name)
	Selector string `json:"selector" validate:"selector"`

	// DoNotTrack indicates whether packets matched by the rules in this policy should go through
	// the data plane's connection tracking, such as Linux conntrack.  If True, the rules in
	// this policy are applied before any data plane connection tracking, and packets allowed by
	// this policy are marked as not to be tracked.
	DoNotTrack bool `json:"doNotTrack,omitempty"`

	// PreDNAT indicates to apply the rules in this policy before any DNAT.
	PreDNAT bool `json:"preDNAT,omitempty"`

	// Types indicates whether this policy applies to ingress, or to egress, or to both.  When
	// not explicitly specified (and so the value on creation is empty or nil), Calico defaults
	// Types according to what IngressRules and EgressRules are present in the policy.  The
	// default is:
	//
	// - [ PolicyTypeIngress ], if there are no EgressRules (including the case where there are
	//   also no IngressRules)
	//
	// - [ PolicyTypeEgress ], if there are EgressRules but no IngressRules
	//
	// - [ PolicyTypeIngress, PolicyTypeEgress ], if there are both IngressRules and EgressRules.

Profile contains the details a security profile resource. A profile is set of security rules to apply on an endpoint. An endpoint (either a host endpoint or an endpoint on a workload) can reference zero or more profiles. The profile rules are applied directly to the endpoint *after* the selector-based security policy has been applied, and in the order the profiles are declared on the endpoint.

func NewProfile

func NewProfile() *Profile

NewProfile creates a new (zeroed) Profile struct with the TypeMetadata initialised to the current version.

func (Profile) GetResourceMetadata added in v1.5.1

func (t Profile) GetResourceMetadata() unversioned.ResourceMetadata

func (Profile) String added in v1.5.1

func (t Profile) String() string

String() returns the human-readable string representation of a Profile instance which is defined by its Name.

type ProfileList

type ProfileList struct {
	unversioned.TypeMetadata
	Metadata unversioned.ListMetadata `json:"metadata,omitempty"`
	Items    []Profile                `json:"items" validate:"dive,omitempty"`
}

A ProfileList contains a list of security Profile resources. List types are returned from List() enumerations on the client interface.

func NewProfileList

func NewProfileList() *ProfileList

	Name string `json:"name,omitempty" validate:"omitempty,namespacedname"`

	// A list of tags that are applied to each endpoint that references this profile.
	Tags []string `json:"tags,omitempty" validate:"omitempty,dive,tag"`

	// The labels to apply to each endpoint that references this profile.  It is expected
	// that many endpoints share the same labels. For example, they could be used to label all
	// “production” workloads with “deployment=prod” so that security policy can be applied
	// to production workloads.
	Labels map[string]string `json:"labels,omitempty" validate:"omitempty,labels"`
}

ProfileMetadata contains the metadata for a security Profile resource.

type ProfileSpec

type ProfileSpec struct {
	// The ordered set of ingress rules.  Each rule contains a set of packet match criteria and
	// a corresponding action to apply.

	// The ordered set of egress rules.  Each rule contains a set of packet match criteria and
	// a corresponding action to apply.
	EgressRules []Rule `json:"egress,omitempty" validate:"omitempty,dive"`
}

ProfileSpec contains the specification for a security Profile resource.

type Rule

type Rule struct {
	Action string `json:"action" validate:"action"`

	// IPVersion is an optional field that restricts the rule to only match a specific IP
	// version.
	IPVersion *int `json:"ipVersion,omitempty" validate:"omitempty,ipversion"`

	// Protocol is an optional field that restricts the rule to only apply to traffic of
	// a specific IP protocol. Required if any of the EntityRules contain Ports
	// (because ports only apply to certain protocols).
	//
	// Must be one of these string values: "tcp", "udp", "icmp", "icmpv6", "sctp", "udplite"
	// or an integer in the range 1-255.
	Protocol *numorstring.Protocol `json:"protocol,omitempty" validate:"omitempty"`

	// ICMP is an optional field that restricts the rule to apply to a specific type and
	// code of ICMP traffic.  This should only be specified if the Protocol field is set to
	// "icmp" or "icmpv6".
	ICMP *ICMPFields `json:"icmp,omitempty" validate:"omitempty"`

	// NotProtocol is the negated version of the Protocol field.
	NotProtocol *numorstring.Protocol `json:"notProtocol,omitempty" validate:"omitempty"`

	// NotICMP is the negated version of the ICMP field.
	NotICMP *ICMPFields `json:"notICMP,omitempty" validate:"omitempty"`

	// Source contains the match criteria that apply to source entity.
	Source EntityRule `json:"source,omitempty" validate:"omitempty"`

	// Destination contains the match criteria that apply to destination entity.
	Destination EntityRule `json:"destination,omitempty" validate:"omitempty"`
}

A Rule encapsulates a set of match criteria and an action. Both selector-based security Policy and security Profiles reference rules - separated out as a list of rules for both ingress and egress packet matching.

Each positive match criteria has a negated version, prefixed with ”Not”. All the match criteria within a rule must be satisfied for a packet to match. A single rule can contain the positive and negative version of a match and both must be satisfied for the rule to match.

	// for the active instance of a container. For example, with Calico CNI, a re-spawned
	// container may use the same endpoint indexing (Node, Orchestrator, Workload, Endpoint)
	// for the new container as for the old - the ActiveInstanceID is used to store an additional
	// unique ID which the CNI plugin uses to determine whether the DEL operation needs to
	// delete the Calico WorkloadEndpoint.
	// This field is not an index field of the WorkloadEndpoint resource.
	ActiveInstanceID string `json:"activeInstanceID,omitempty" validate:"omitempty,name"`
