# Consul Connect Proxy
|
|
|
|
Command: `consul connect proxy`
|
|
|
|
The connect proxy command is used to run Consul's built-in mTLS proxy for
|
|
use with Connect. This can be used in production to enable a Connect-unaware
|
|
application to accept and establish Connect-based connections. This proxy
|
|
can also be used in development to connect to Connect-enabled services.
|
|
|
|
|
|
## Usage
|
|
|
|
Usage: `consul connect proxy [options]`
|
|
|

#### Proxy Options
|
|
|
|
* `-sidecar-for` - The _ID_ (not name if they differ) of the service instance
|
|
this proxy will represent. The target service doesn't need to exist on the
|
|
local agent yet but a [sidecar proxy
|
|
registration](/docs/connect/registration/service-registration.html) with
|
|
`proxy.destination_service_id` equal to the passed value must be present. If
|
|
multiple proxy registrations targeting the same local service instance are
|
|
present the command will error and `-proxy-id` should be used instead.
|
|
|
|
* `-proxy-id` - The [proxy
|
|
service](/docs/connect/registration/service-registration.html) ID on the
|
|
local agent. This must already be present on the local agent.
|
|
|
|
* `-log-level` - Specifies the log level.
|
|
|
|
* `-pprof-addr` - Enable debugging via pprof. Providing a host:port (or just ':port')
|
|
enables profiling HTTP endpoints on that address.
|
|
|
|
* `-service` - Name of the service this proxy is representing. This service
|
|
doesn't need to actually exist in the Consul catalog, but proper ACL
|
|
permissions (`service:write`) are required. This and the remaining options can
|
|
be used to setup a proxy that is not registered already with local config
|
|
[useful for development](/docs/connect/dev.html).
|
|
|
|
* `-upstream` - Upstream service to support connecting to. The format should be
|
|
'name:addr', such as 'db:8181'. This will make 'db' available on port 8181.
|
|
When a regular TCP connection is made to port 8181, the proxy will service
|
|
discover "db" and establish a Connect mTLS connection identifying as
|
|
the `-service` value. This flag can be repeated multiple times.
|
|
|
|
* `-listen` - Address to listen for inbound connections to the proxied service.
|
|
Must be specified with -service and -service-addr. If this isn't specified,
|
|
an inbound listener is not started.
|
|
|
|
* `-service-addr` - Address of the local service to proxy. Required for
|
|
`-listen`.
|
|
|
|
* `-register` - Self-register with the local Consul agent, making this
|
|
proxy available as Connect-capable service in the catalog. This is only
|
|
useful with `-listen`.
|
|
|
|
* `-register-id` - Optional ID suffix for the service when `-register` is set to
|
|
disambiguate the service ID. By default the service ID is "<service>-proxy"
|
|
where `<service>` is the `-service` value. In most cases it is now preferable
|
|
to use [`consul services register`](/docs/commands/services/register.html) to
|
|
register a fully configured proxy instance rather than specify config and
|
|
registration via this command.
|
|
|
|
## Examples
|
|
|
|
The example below shows how to start a local proxy for establishing outbound
|
|
connections to "db" representing the frontend service. Once running, any
|
|
process that creates a TCP connection to the specified port (8181) will
|
|
establish a mutual TLS connection to "db" identified as "frontend".
|
|
|
|
```text
|
|
$ consul connect proxy -service frontend -upstream db:8181
|
|
```
|
|
|
|
The next example starts a local proxy that also accepts inbound connections
|
|
on port 8443, authorizes the connection, then proxies it to port 8080:
|
|
|
|
```text
|
|
$ consul connect proxy \
|
|
-service frontend \
|
|
-service-addr 127.0.0.1:8080 \
|
|
-listen ':8443'
|
|
```
