Resource definitions

This section describes the set of valid resource types that can be managed through calicoctl or kubectl.

While resources may be supplied in YAML or JSON format, this guide provides examples in YAML.

Overview of resource structure

The calicoctl commands for resource management (create, apply, delete, replace, get) all take resource manifests as input.

Each manifest may contain a single resource (e.g. a profile resource), or a list of multiple resources (e.g. a profile and two hostEndpoint resources).

The general structure of a single resource is as follows:

apiVersion: projectcalico.org/v3
kind: <type of resource>
metadata:
  # Identifying information
  name: <name of resource>
  ...
spec:
  # Specification of the resource
  ...

Schema

Field	Description	Accepted Values	Schema
apiVersion	Indicates the version of the API that the data corresponds to.	projectcalico.org/v3	string
kind	Specifies the type of resource described by the YAML document.		kind
metadata	Contains information used to uniquely identify the particular instance of the resource.		map
spec	Contains the resource specification.		map

Supported kinds

The following resources are supported:

• BGPConfiguration
• BGPPeer
• FelixConfiguration
• GlobalNetworkPolicy
• GlobalNetworkSet
• HostEndpoint
• IPPool
• NetworkPolicy
• NetworkSet
• Node
• Profile
• WorkloadEndpoint

Resource name requirements

Every resource must have the name field specified. Name must be unique within a namespace. Name required when creating resources, and cannot be updated. A valid resource name can have alphanumeric characters with optional ., _, or -. of up to 128 characters total.

Multiple resources in a single file

A file may contain multiple resource documents specified in a YAML list format. For example, the following is the contents of a file containing two HostEndpoint resources:

- apiVersion: projectcalico.org/v3
  kind: HostEndpoint
  metadata:
    name: endpoint1
    labels:
      type: database
  spec:
    interface: eth0
    node: host1
    profiles:
      - prof1
      - prof2
    expectedIPs:
      - 1.2.3.4
      - '00:bb::aa'
- apiVersion: projectcalico.org/v3
  kind: HostEndpoint
  metadata:
    name: endpoint2
    labels:
      type: frontend
  spec:
    interface: eth1
    node: host1
    profiles:
      - prof1
      - prof2
    expectedIPs:
      - 1.2.3.5
