## Run

### Start daemon

You should have built and installed lcrd and lcrc. To run the daemon:
```sh
$ sudo lcrd  # run the iSulad server with default socket name and default log level and images manage function
```

### Operations on containers:

```sh
$ sudo lcrc ps -a    # list containers
# create a container 'test' with image busybox
$ sudo lcrc create -t -n test busybox
$ sudo lcrc start test   # start the container 'test'
$ sudo lcrc kill test    # kill the container 'test'
$ sudo lcrc rm test    # remove the container 'test'
```
