The /config endpoints are for managing centralized configuration

in Consul.

# Config HTTP Endpoint
|
|
|
|
The `/config` endpoints create, update, delete and query central configuration
|
|
entries registered with Consul. See the
|
|
[agent configuration](/docs/agent/options#enable_central_service_config)
|
|
for more information on how to enable this functionality for centrally
|
|
configuring services and [configuration entries docs](/docs/agent/config-entries) for a description
|
|
of the configuration entries content.
|
|
|
|
## Apply Configuration
|
|
|
|
This endpoint creates or updates the given config entry.
|
|
|
|
| Method | Path | Produces |
|
|
| ------ | --------- | ------------------ |
|
|
| `PUT` | `/config` | `application/json` |
|
|
|
|
The table below shows this endpoint's support for
|
|
[blocking queries](/api/features/blocking),
|
|
[consistency modes](/api/features/consistency),
|
|
[agent caching](/api/features/caching), and
|
|
[required ACLs](/api#authentication).
|
|
|
|
| Blocking Queries | Consistency Modes | Agent Caching | ACL Required |
|
|
| ---------------- | ----------------- | ------------- | ------------------------------------------------- |
|
|
| `NO` | `none` | `none` | `service:write`<br />`operator:write`<sup>1</sup> |
|
|
|
|
<p>
|
|
<sup>1</sup> The ACL required depends on the config entry kind being updated:

|
|
| ingress-gateway | `operator:write` |
|
|
| proxy-defaults | `operator:write` |
|
|
| service-defaults | `service:write` |
|
|
| service-intentions | `intentions:write` |
|
|
| service-resolver | `service:write` |
|
|
| service-router | `service:write` |
|
|
| service-splitter | `service:write` |
|
|
| terminating-gateway | `operator:write` |
|
|
|
|
The corresponding CLI command is [`consul config write`](/commands/config/write).
|
|
|
|
### Parameters
|
|
|
|
- `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.
|
|
|
|
- `cas` `(int: 0)` - Specifies to use a Check-And-Set operation. If the index is
|
|
0, Consul will only store the entry if it does not already exist. If the index is
|
|
non-zero, the entry is only set if the current index matches the `ModifyIndex`
|
|
of that entry.
|
|
|
|
- `ns` `(string: "")` <EnterpriseAlert inline /> - Specifies the namespace the config
|
|
entry will apply to. 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. Added in Consul 1.7.0.
|
|
|
|

The corresponding CLI command is [`consul config delete`](/commands/config/delete).
|
|
|
|
### Parameters
|
|
|
|
- `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.
|
|
|
|
- `kind` `(string: <required>)` - Specifies the kind of the entry to delete. This
|
|
is specified as part of the URL.
|
|
|
|
- `name` `(string: <required>)` - Specifies the name of the entry to delete. This
|
|
is specified as part of the URL. The name of the `proxy-defaults` config entry
|
|
must be `global`, and the name of the `mesh` config entry must be `mesh`.
|
|
|
|
- `ns` `(string: "")` <EnterpriseAlert inline /> - Specifies the namespace to delete from.
|
|
This value may be provided by either the `ns` URL query parameter or in the

|
|
|
|
- `cas` `(int: 0)` - Specifies to use a Check-And-Set operation. Unlike `PUT`,
|
|
the index must be greater than 0 for Consul to take any action: a 0 index will
|
|
not delete the config entry. If the index is non-zero, the config entry is only
|
|
deleted if the index matches the `ModifyIndex` of that config entry. This is
|
|
specified as part of the URL as a query parameter.
|
|
