## Examples
|
|
|
|
|
|
|
|
|
|
The example below shows using the `expose` command to make the `foo` service available
|
|
|
|
|
through the Ingress gateway service `ingress`. The protocol argument is optional and
|
|
|
|
|
defaults to `tcp` if not provided.
|
|
|
|
|
|
|
|
|
|
```shell-session
|
|
|
|
|
$ consul connect expose -service=foo -ingress-gateway=ingress -port 8888 -protocol=tcp
|
|
|
|
|
Successfully updated config entry for ingress service "ingress"
|
|
|
|
|
Successfully set up intention for "ingress" -> "foo"
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
Running the command again when the config entry/intention are already set up will result
|
|
|
|
|
in a no-op:
|
|
|
|
|
|
|
|
|
|
```shell-session
|
|
|
|
|
$ consul connect expose -service=foo -ingress-gateway=ingress -port 8888 -protocol=tcp
|
|
|
|
|
Service "foo" already exposed through listener with port 8888
|
|
|
|
|
Intention already exists for "ingress" -> "foo"
|
|
|
|
|
```
|
