A Connect-aware proxy enables unmodified applications to use Connect. A per-service proxy sidecar transparently handles inbound and outbound service connections, automatically wrapping and verifying TLS connections.

# Connect Configuration
|
||
|
|
|
||
|
|
There are many configuration options exposed for Connect. The only option
|
||
|
|
that must be set is the "enabled" option on Consul Servers to enable Connect.
|
||
|
|
All other configurations are optional and have reasonable defaults.
|
||
|
|
|
||
|
|
## Enable Connect on the Cluster
|
||
|
|
|
||
|
|
The first step to use Connect is to enable Connect for your Consul
|
||
|
|
cluster. By default, Connect is disabled. Enabling Connect requires changing
|
||
|
|
the configuration of only your Consul _servers_ (not client agents). To enable
|
||
|
|
Connect, add the following to a new or existing
|
||
|
|
[server configuration file](/docs/agent/options.html). In HCL:
|
||
|
|
|
||
|
|
```hcl
|
||
|
|
connect {
|
||
|
|
enabled = true
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
This will enable Connect and configure your Consul cluster to use the
|
||
|
|
built-in certificate authority for creating and managing certificates.
|
||
|
|
You may also configure Consul to use an external
|
||
|
|
[certificate management system](/docs/connect/ca.html), such as
|
||
|
|
[Vault](https://vaultproject.io).
|
||
|
|
|
||
|
|
No agent-wide configuration is necessary for non-server agents. Services
|
||
|
|
and proxies may always register with Connect settings, but they will fail to
|
||
|
|
retrieve or verify any TLS certificates. This causes all Connect-based
|
||
|
|
connection attempts to fail until Connect is enabled on the server agents.
|
||
|
|
|
||
|
|
-> **Note:** Connect is enabled by default when running Consul in
|
||
|
|
dev mode with `consul agent -dev`.
