# Control the daemon
The `garage` binary has two purposes:
- it acts as a daemon when launched with `garage server ...`
- it acts as a control tool for the daemon when launched with any other command
In this section, we will see how to use the `garage` binary as a control tool for the daemon we just started.
You first need to get a shell having access to this binary, which depends of your configuration:
- with `docker`, run `sudo docker exec -ti garaged bash`, you will now have a shell
where the Garage binary is available as `/garage/garage`
- with `systemd`, simply run `/usr/local/bin/garage` if you followed previous instructions
*You can also install the binary on your machine to remotely control the cluster.*
## Talk to the daemon and create an alias
`garage` requires 4 options to talk with the daemon:
```
--ca-cert <ca-cert>
--client-cert <client-cert>
--client-key <client-key>
-h, --rpc-host <rpc-host>
```
The 3 first ones are certificates and keys needed by TLS, the last one is simply the address of garage's RPC endpoint.
Because we configure garage directly from the server, we do not need to set `--rpc-host`.
To avoid typing the 3 first options each time we want to run a command, we will create an alias.
### test deployment
If you have simply deployed Garage on your local machine, without TLS, you can invoke
`garage` directly without any of these parameters and without making a `garagectl` alias
(replace mentions of `garagectl` in the next sections by `garage`).
### `docker` alias
```bash
alias garagectl='/garage/garage \
--ca-cert /etc/garage/pki/garage-ca.crt \
--client-cert /etc/garage/pki/garage.crt \
--client-key /etc/garage/pki/garage.key'
```
### raw binary alias
```bash
alias garagectl='/usr/local/bin/garage \
--ca-cert /etc/garage/pki/garage-ca.crt \
--client-cert /etc/garage/pki/garage.crt \
--client-key /etc/garage/pki/garage.key'
```
Of course, if your deployment does not match exactly one of this alias, feel free to adapt it to your needs!
## Test the alias
You can test your alias by running a simple command such as:
```
garagectl status
```
You should get something like that as result:
```
Healthy nodes:
2a638ed6c775b69a… 37f0ba978d27 [::ffff:172.20.0.101]:3901 UNCONFIGURED/REMOVED
68143d720f20c89d… 9795a2f7abb5 [::ffff:172.20.0.103]:3901 UNCONFIGURED/REMOVED
8781c50c410a41b3… 758338dde686 [::ffff:172.20.0.102]:3901 UNCONFIGURED/REMOVED
```
...which means that you are ready to [configure your cluster](05_cluster.md)!
