# Service - Agent HTTP API
2018-10-11 17:48:51 +00:00
The `/agent/service` endpoints interact with services on the local agent in
2017-04-04 16:33:22 +00:00
Consul. These should not be confused with services in the catalog.
## List Services
This endpoint returns all the services that are registered with
the local agent. These services were either provided through configuration files
or added dynamically using the HTTP API.
It is important to note that the services known by the agent may be different
from those reported by the catalog. This is usually due to changes being made
while there is no leader elected. The agent performs active
2020-04-09 23:46:54 +00:00
[anti-entropy](/docs/internals/anti-entropy), so in most situations
2017-04-04 16:33:22 +00:00
everything will be in sync within a few seconds.

## Get Service Configuration
This endpoint was added in Consul 1.3.0 and returns the full service definition
for a single service instance registered on the local agent. It is used by
2020-04-09 23:46:54 +00:00
[Connect proxies](/docs/connect/proxies) to discover the embedded proxy
configuration that was registered with the instance.
It is important to note that the services known by the agent may be different
from those reported by the catalog. This is usually due to changes being made
while there is no leader elected. The agent performs active
2020-04-09 23:46:54 +00:00
[anti-entropy](/docs/internals/anti-entropy), so in most situations
everything will be in sync within a few seconds.

```
The response has the same structure as the [service
2020-04-09 23:46:54 +00:00
definition](/docs/agent/services) with one extra field `ContentHash` which
contains the [hash-based blocking
2020-04-09 23:46:54 +00:00
query](/api/features/blocking#hash-based-blocking-queries) hash for the result. The
same hash is also present in `X-Consul-ContentHash`.
## Get local service health
Retrieve an aggregated state of service(s) on the local agent by name.
This endpoints support JSON format and text/plain formats, JSON being the
default. In order to get the text format, you can append `?format=text` to
the URL or use Mime Content negotiation by specifying a HTTP Header
`Accept` starting with `text/plain`.
| Method | Path | Produces |
| ------ | ------------------------------------------------------ | ------------------ |
| `GET` | `/agent/health/service/name/:service_name` | `application/json` |
| `GET` | `/agent/health/service/name/:service_name?format=text` | `text/plain` |
The table below shows this endpoint's support for
2020-04-09 23:46:54 +00:00
[blocking queries](/api/features/blocking),
[consistency modes](/api/features/consistency),
[agent caching](/api/features/caching), and
2020-04-09 23:20:00 +00:00
[required ACLs](/api#authentication).
| Blocking Queries | Consistency Modes | Agent Caching | ACL Required |
| ---------------- | ----------------- | ------------- | -------------- |
| `NO` | `none` | `none` | `service:read` |
Those endpoints return the aggregated values of all healthchecks for the
service instance(s) and will return the corresponding HTTP codes:
| Result | Meaning |
2020-04-06 20:27:35 +00:00
| ------ | --------------------------------------------------------------- |
| `200` | All healthchecks of every matching service instance are passing |
| `400` | Bad parameter (missing service name of id) |
| `404` | No such service id or name |
| `429` | Some healthchecks are passing, at least one is warning |
| `503` | At least one of the healthchecks is critical |
Those endpoints might be useful for the following use-cases:
2020-04-06 20:27:35 +00:00
- a load-balancer wants to check IP connectivity with an agent and retrieve
the aggregated status of given service
2020-04-06 20:27:35 +00:00
- create aliases for a given service (thus, the healthcheck of alias uses
http://localhost:8500/v1/agent/service/id/aliased_service_id healthcheck)
##### Note
2020-04-06 20:27:35 +00:00
If you know the ID of service you want to target, it is recommended to use
2020-04-13 21:24:10 +00:00
[`/v1/agent/health/service/id/:service_id`](/api/agent/service#get-local-service-health-by-its-id)
so you have the result for the service only. When requesting
`/v1/agent/health/service/name/:service_name`, the caller will receive the
worst state of all services having the given name.
### Sample Requests

service definition keys for compatibility with the config file format.
2017-04-04 16:33:22 +00:00
- `Name` `(string: <required>)` - Specifies the logical name of the service.
Many service instances may share the same logical service name. We recommend using
[valid DNS labels](https://en.wikipedia.org/wiki/Hostname#Restrictions_on_valid_hostnames)
2020-04-09 23:46:54 +00:00
for [compatibility with external DNS](/docs/agent/services#service-and-tag-names-with-dns).
2017-04-04 16:33:22 +00:00
- `ID` `(string: "")` - Specifies a unique ID for this service. This must be
unique per _agent_. This defaults to the `Name` parameter if not provided.
- `Tags` `(array<string>: nil)` - Specifies a list of tags to assign to the
service. These tags can be used for later filtering and are exposed via the APIs.

2017-04-04 16:33:22 +00:00
- `Address` `(string: "")` - Specifies the address of the service. If not
provided, the agent's address is used as the address for the service during
DNS queries.
- `TaggedAddresses` `(map<string|object>: nil)` - Specifies a map of explicit LAN
and WAN addresses for the service instance. Both the address and port can be
specified within the map values.
- `Meta` `(map<string|string>: nil)` - Specifies arbitrary KV metadata
linked to the service instance.
- `Port` `(int: 0)` - Specifies the port of the service.
- `Kind` `(string: "")` - The kind of service. Defaults to "" which is a
typical Consul service. This value may also be "connect-proxy" for

[configuration for Connect](/docs/connect/configuration). See the

[Connect Structure](#connect-structure) section below for supported fields.
2017-04-04 16:33:22 +00:00
- `Check` `(Check: nil)` - Specifies a check. Please see the
2020-04-09 23:46:54 +00:00
[check documentation](/api/agent/check) for more information about the
accepted fields. If you don't provide a name or id for the check then they
will be generated. To provide a custom id and/or name set the `CheckID`
and/or `Name` field.
- `Checks` `(array<Check>: nil)` - Specifies a list of checks. Please see the
2020-04-09 23:46:54 +00:00
[check documentation](/api/agent/check) for more information about the
accepted fields. If you don't provide a name or id for the check then they
will be generated. To provide a custom id and/or name set the `CheckID`
and/or `Name` field. The automatically generated `Name` and `CheckID` depend
on the position of the check within the array, so even though the behavior is
2017-05-17 18:22:00 +00:00
deterministic, it is recommended for all checks to either let consul set the
`CheckID` by leaving the field empty/omitting it or to provide a unique value.
2017-04-04 16:33:22 +00:00
- `EnableTagOverride` `(bool: false)` - Specifies to disable the anti-entropy
feature for this service's tags. If `EnableTagOverride` is set to `true` then
2020-04-09 23:46:54 +00:00
external agents can update this service in the [catalog](/api/catalog)
2017-04-04 16:33:22 +00:00
and modify the tags. Subsequent local sync operations by this agent will
ignore the updated tags. For instance, if an external agent modified both the
tags and the port for this service and `EnableTagOverride` was set to `true`
then after the next sync cycle the service's port would revert to the original
value but the tags would maintain the updated value. As a counter example, if
an external agent modified both the tags and port for this service and
`EnableTagOverride` was set to `false` then after the next sync cycle the
service's port _and_ the tags would revert to the original value and all
modifications would be lost.
- `Weights` `(Weights: nil)` - Specifies weights for the service. Please see the
2020-04-09 23:46:54 +00:00
[service documentation](/docs/agent/services) for more information about
weights. If this field is not provided weights will default to
`{"Passing": 1, "Warning": 1}`.
2020-04-06 20:27:35 +00:00
It is important to note that this applies only to the locally registered
service. If you have multiple nodes all registering the same service their
`EnableTagOverride` configuration and all other service configuration items
are independent of one another. Updating the tags for the service registered
on one node is independent of the same service (by name) registered on
another node. If `EnableTagOverride` is not specified the default value is
2020-04-09 23:46:54 +00:00
`false`. See [anti-entropy syncs](/docs/internals/anti-entropy) for
2020-04-06 20:27:35 +00:00
more info.
2017-04-04 16:33:22 +00:00
#### Connect Structure
For the `Connect` field, the parameters are:
- `Native` `(bool: false)` - Specifies whether this service supports
2020-04-09 23:46:54 +00:00
the [Connect](/docs/connect) protocol [natively](/docs/connect/native).
If this is true, then Connect proxies, DNS queries, etc. will be able to
service discover this service.
- `Proxy` `(Proxy: nil)` -
2020-04-09 23:46:54 +00:00
[**Deprecated**](/docs/connect/proxies/managed-deprecated) Specifies that
a managed Connect proxy should be started for this service instance, and
optionally provides configuration for the proxy. The format is as documented
2020-04-09 23:46:54 +00:00
in [Managed Proxy Deprecation](/docs/connect/proxies/managed-deprecated).
- `SidecarService` `(ServiceDefinition: nil)` - Specifies an optional nested
service definition to register. For more information see
2020-04-09 23:46:54 +00:00
[Sidecar Service Registration](/docs/connect/registration/sidecar-service).

## Deregister Service
This endpoint removes a service from the local agent. If the service does not
exist, no action is taken.
The agent will take care of deregistering the service with the catalog. If there
is an associated check, that is also deregistered.
