# Consul Config Write

|
|
|
Command: `consul config write`
|
|
|
|
Corresponding HTTP API Endpoint: [\[PUT\] /v1/config](/consul/api-docs/config#apply-configuration)
|
|
|
|
The `config write` command creates or updates a centralized config entry.
|

See the [configuration entries docs](/consul/docs/agent/config-entries) for more
|
|
details about configuration entries.
|
|
|
|
The table below shows this command's [required ACLs](/consul/api-docs/api-structure#authentication). Configuration of
|
|
[blocking queries](/consul/api-docs/features/blocking) and [agent caching](/consul/api-docs/features/caching)
|
|
are not supported from commands, but may be from the corresponding HTTP endpoint.

## Usage
|
|
|
|
Usage: `consul config write [options] FILE`
|
|
|
|
#### Command Options
|
|
|
|
- `-cas` - 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.
|
|
|
|
#### Enterprise Options
|
|
|
|
@include 'http_api_partition_options.mdx'
|
|
|
|
@include 'http_api_namespace_options.mdx'
|
|
|
|
#### API Options
|
|
|
|
@include 'http_api_options_client.mdx'
|
|
|
|
## Examples
|
|
|
|
From file:
|
|
|
|
$ consul config write web-defaults.json
|
|
|
|
From stdin:
|
|
|
|
$ consul config write -
|
|
|
|
### Config Entry examples
|
|
|
|
All config entries must have a `Kind` when registered. See
|
|
[Service Mesh - Config Entries](/consul/docs/connect/config-entries) for the list of
|
|
supported config entries.
|
|
|
|
#### Service defaults
|
|
|
|
Service defaults control default global values for a service in the service mesh.
|
|
For example, the following configuration defines that all instances of the `web`
|
|
service use the `http` protocol.
|
|
|
|
```json
|
|
{
|
|
"Kind": "service-defaults",
|
|
"Name": "web",
|
|
"Protocol": "http"
|
|
}
|
|
```
|
|
|
|
For more information, refer to the [service defaults configuration reference](/consul/docs/connect/config-entries/service-defaults).
|
|
|
|
#### Proxy defaults
|
|
|
|
Proxy defaults lets you configure global config defaults across all proxies
|
|
in the service mesh. Currently, it supports only one global entry.
|
|
For example, the following configuration overrides a default timeout for all
|
|
Envoy proxies.
|
|
|
|
```json
|
|
{
|
|
"Kind": "proxy-defaults",
|
|
"Name": "global",
|
|
"Config": {
|
|
"local_idle_timeout_ms": 20000
|
|
}
|
|
}
|
|
```
|
|
|
|
For more information, refer to the [proxy defaults configuration reference](/consul/docs/connect/config-entries/proxy-defaults).
