# Built-In Proxy Options
|
|
|
|
~> **Note:** The built-in proxy is not supported for production deployments. It does not
|
|
support many of the Connect service mesh features, and is not under active development.
|
|
The [Envoy proxy](/docs/connect/proxies/envoy) should be used for production deployments.
|
|
|
|
Consul comes with a built-in L4 proxy for testing and development with Consul
|
|
Connect service mesh.
|
|
|
|
|
|
## Getting Started
|
|
|
|
To get started with the built-in proxy and see a working example you can follow the [Getting Started](https://learn.hashicorp.com/tutorials/consul/get-started-service-networking) tutorial.
|
|
|
|
## Proxy Config Key Reference
|
|
|
|
Below is a complete example of all the configuration options available
|
|
for the built-in proxy.
|
|
|
|
```json
|
|
{
|
|
"service": {
|
|
...
|
|
"connect": {
|
|
"proxy": {
|
|
"config": {
|
|
"bind_address": "0.0.0.0",
|
|
"bind_port": 20000,
|
|
"local_service_address": "127.0.0.1:1234",
|
|
"local_connect_timeout_ms": 1000,
|
|
"handshake_timeout_ms": 10000,
|
|
"upstreams": [...]
|
|
},
|
|
"upstreams": [
|
|
{
|
|
...
|
|
"config": {
|
|
"connect_timeout_ms": 1000
|
|
}
|
|
}
|
|
]
|
|
}
|
|
}
|
|
}
|
|
}
|
|
```
|
|
|
|
All fields are optional with a reasonable default.
|
|
|
|
- `bind_address` - The address the proxy will bind its
|
|
_public_ mTLS listener to. It defaults to the same address the agent binds to.
|
|
|
|
- `bind_port` - The port the proxy will bind its _public_
|
|
mTLS listener to. If not provided, the agent will attempt to assign one from its
|
|
[configured proxy port range](/docs/agent/config/config-files#sidecar_min_port) if available.
|
|
By default the range is [20000, 20255] and the port is selected at random from
|
|
that range.
|
|
|
|
- `local_service_address`- The `[address]:port`
|
|
that the proxy should use to connect to the local application instance. By default
|
|
it assumes `127.0.0.1` as the address and takes the port from the service definition's
|
|
`port` field. Note that allowing the application to listen on any non-loopback
|
|
address may expose it externally and bypass Connect's access enforcement. It may
|
|
be useful though to allow non-standard loopback addresses or where an alternative
|
|
known-private IP is available for example when using internal networking between
|
|
containers.
|
|
|
|
- `local_connect_timeout_ms` - The number
|
|
of milliseconds the proxy will wait to establish a connection to the _local application_
|
|
before giving up. Defaults to `1000` or 1 second.
|
|
|
|
- `handshake_timeout_ms` - The number of milliseconds
|
|
the proxy will wait for _incoming_ mTLS connections to complete the TLS handshake.
|
|
Defaults to `10000` or 10 seconds.
|
|
|
|
- `upstreams`- **Deprecated** Upstreams are now specified
|
|
in the `connect.proxy` definition. Upstreams specified in the opaque config map
|
|
here will continue to work for compatibility but it's strongly recommended that
|
|
you move to using the higher level [upstream configuration](/docs/connect/registration/service-registration#upstream-configuration-reference).
|
|
|
|
## Proxy Upstream Config Key Reference
|
|
|
|
All fields are optional with a reasonable default.
|
|
|
|
- `connect_timeout_ms` - The number of milliseconds
|
|
the proxy will wait to establish a TLS connection to the discovered upstream instance
|
|
before giving up. Defaults to `10000` or 10 seconds.
