»Catalog HTTP API

The /catalog endpoints register and deregister nodes, services, and checks in Consul. The catalog should not be confused with the agent, since some of the API methods look similar.

»Register Entity

This endpoint is a low-level mechanism for registering or updating entries in the catalog. It is usually preferable to instead use the agent endpoints for registration as they are simpler and perform anti-entropy.

MethodPathProduces
PUT/catalog/registerapplication/json

The table below shows this endpoint's support for blocking queries, consistency modes, agent caching, and required ACLs.

Blocking QueriesConsistency ModesAgent CachingACL Required
NOnonenonenode:write,service:write

»Parameters

  • ID (string: "") - An optional UUID to assign to the node. This must be a 36-character UUID-formatted string.

  • Node (string: <required>) - Specifies the node ID to register.

  • Address (string: <required>) - Specifies the address to register.

  • Datacenter (string: "") - Specifies the datacenter, which defaults to the agent's datacenter if not provided.

  • TaggedAddresses (map<string|string>: nil) - Specifies the tagged addresses.

  • NodeMeta (map<string|string>: nil) - Specifies arbitrary KV metadata pairs for filtering purposes.

  • Service (Service: nil) - Specifies to register a service. If ID is not provided, it will be defaulted to the value of the Service.Service property. Only one service with a given ID may be present per node. We recommend using valid DNS labels for service definition names for compatibility with external DNS. The service Tags, Address, Meta, and Port fields are all optional. For more information about these fields and the implications of setting them, see the Service - Agent API page as registering services differs between using this or the Services Agent endpoint.

  • Check (Check: nil) - Specifies to register a check. The register API manipulates the health check entry in the Catalog, but it does not setup the script, TTL, or HTTP check to monitor the node's health. To truly enable a new health check, the check must either be provided in agent configuration or set via the agent endpoint.

    The CheckID can be omitted and will default to the value of Name. As with Service.ID, the CheckID must be unique on this node. Notes is an opaque field that is meant to hold human-readable text. If a ServiceID is provided that matches the ID of a service on that node, the check is treated as a service level health check, instead of a node level health check. The Status must be one of passing, warning, or critical.

    The Definition field can be provided with details for a TCP or HTTP health check. For more information, see the Health Checks page.

    Multiple checks can be provided by replacing Check with Checks and sending an array of Check objects.

  • SkipNodeUpdate (bool: false) - Specifies whether to skip updating the node's information in the registration. This is useful in the case where only a health check or service entry on a node needs to be updated or when a register request is intended to update a service entry or health check. In both use cases, node information will not be overwritten, if the node is already registered. Note, if the parameter is enabled for a node that doesn't exist, it will still be created.

  • ns (string: "")

    Enterprise
    - Specifies the namespace in which the service and checks will be registered. This value may be provided by either the ns URL query parameter or in the X-Consul-Namespace header. Additionally, the namespace may be provided within the Service or Check fields but if present in multiple places, they must all be the same. If not provided, the namespace will be inherited from the request's ACL token or will default to the default namespace. Added in Consul 1.7.0.

It is important to note that Check does not have to be provided with Service and vice versa. A catalog entry can have either, neither, or both.

»Parameters

The behavior of the endpoint depends on what keys are provided.

  • Node (string: <required>) - Specifies the ID of the node. If no other values are provided, this node, all its services, and all its checks are removed.

  • Datacenter (string: "") - Specifies the datacenter, which defaults to the agent's datacenter if not provided.

  • CheckID (string: "") - Specifies the ID of the check to remove.

  • ServiceID (string: "") - Specifies the ID of the service to remove. The service and all associated checks will be removed.

  • Namespace (string: "")

    Enterprise
    - Specifies the namespace in which the service and checks will be deregistered. If not provided in the JSON body, the value of the ns URL query parameter or the X-Consul-Namespace header will be used. If not provided, the namespace will be inherited from the request's ACL token or will default to the default namespace. Added in Consul 1.7.0.

This endpoint returns the list of all known datacenters. The datacenters will be sorted in ascending order based on the estimated median round trip time from the server to the servers in that datacenter.

This endpoint does not require a cluster leader and will succeed even during an availability outage. Therefore, it can be used as a simple check to see if any Consul servers are routable.

»List Nodes for Connect-capable Service

Blocking QueriesConsistency ModesAgent CachingACL Required
YESallnoneservice:read

»Parameters

  • gateway (string: <required>) - Specifies the name of the node for which to list services. This is specified as part of the URL.

  • dc (string: "") - Specifies the datacenter to query. This will default to the datacenter of the agent being queried. This is specified as part of the URL as a query parameter.

  • ns (string: "")

    Enterprise
    - Specifies the namespace of the gateway. This value may be provided by either the ns URL query parameter or in the X-Consul-Namespace header. If not provided, the namespace will be inherited from the request's ACL token or will default to the default namespace. The * wildcard may be used and then services from all namespaces will be returned. Added in Consul 1.7.0.
