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.

	// Selector is an optional field that contains a selector expression (see Policy for
	// sample syntax).  Only traffic that originates from (terminates at) endpoints matching
	// the selector will be matched.
	//
	// Note that: in addition to the negated version of the Selector (see NotSelector below), the
	// selector expression syntax itself supports negation.  The two types of negation are subtly
	// different. One negates the set of matched endpoints, the other negates the whole match:
	//
	//	Selector = "!has(my_label)" matches packets that are from other Calico-controlled
	// 	endpoints that do not have the label “my_label”.
	//
	// 	NotSelector = "has(my_label)" matches packets that are not from Calico-controlled
	// 	endpoints that do have the label “my_label”.
	//

	// former is limited to packets from Calico-controlled endpoints.
	Selector string `json:"selector,omitempty" validate:"omitempty,selector"`

	// Ports is an optional field that restricts the rule to only apply to traffic that has a
	// source (destination) port that matches one of these ranges/values. This value is a
	// list of integers or strings that represent ranges of ports.
	//
	// Since only some protocols have ports, if any ports are specified it requires the
	// Protocol match in the Rule to be set to "tcp" or "udp".

}

An EntityRule is a sub-component of a Rule comprising the match criteria specific to a particular entity (that is either the source or destination).

A source EntityRule matches the source endpoint and originating traffic. A desination EntityRule matches the destination endpoint and terminating traffic.

	// The expected IP addresses (IPv4 and IPv6) of the endpoint.
	// If "InterfaceName" is not present, Calico will look for an interface matching any
	// of the IPs in the list and apply policy to that.
	//
	// Note:
	// 	When using the selector|tag match criteria in an ingress or egress security Policy
	// 	or Profile, Calico converts the selector into a set of IP addresses. For host
	// 	endpoints, the ExpectedIPs field is used for that purpose. (If only the interface
	// 	name is specified, Calico does not learn the IPs of the interface for use in match
	// 	criteria.)
	ExpectedIPs []net.IP `json:"expectedIPs,omitempty" validate:"omitempty,dive,ip"`

	// A list of identifiers of security Profile objects that apply to this endpoint. Each

}

IPPool contains the details of a Calico IP pool resource. A pool resource is used by Calico in two ways:

  • to provide a set of IP addresses from which Calico IPAM assigns addresses for workloads.
  • to provide configuration specific to IP address range, such as configuration for the BGP daemon (e.g. when to use a GRE tunnel to encapsulate packets between compute hosts).

type Node 

type Node struct {
	unversioned.TypeMetadata
	Metadata NodeMetadata `json:"metadata,omitempty"`
	Spec     NodeSpec     `json:"spec,omitempty"`
}

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.

func NewNode 

func NewNode() *Node

NewNode creates a new (zeroed) NodeList struct with the TypeMetadata initialised to the current version.

type NodeBGPSpec 

type NodeBGPSpec struct {

	// IPv6Address is the IPv6 address of this node.  At least one of the
	// IPv4 and IPv6 addresses should be specified.

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.

func NewPolicy 

func NewPolicy() *Policy

NewPolicy creates a new (zeroed) Policy struct with the TypeMetadata initialised to the current version.

	// Policies with higher "order" are applied after those with lower
	// order.  If the order is omitted, it may be considered to be "infinite" - i.e. the
	// policy will be applied last.  Policies with identical order will be applied in
	// alphanumerical order based on the Policy "Name".
	Order *float64 `json:"order,omitempty"`

	// 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"`

	// 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)
