Command: `host-sets add-hosts`
The `host-sets add-hosts` command lets you add hosts to host sets, if the types match and it is allowed by the host set type.
## Example
This example adds the hosts `hst_1234567890` and `hst_0987654321` to the host set `hsst_1234567890`:
```shell-session
$ boundary host-sets add-hosts -id hsst_1234567890 -host hst_1234567890 -host hst_0987654321
```
## Usage
```shell-session
$ boundary host-sets add-hosts [options] [args]
```
### Command options
- `-host=` - The hosts you want to add to the host set.
You can specify multiple hosts.
- `-id=` - The ID of the host set you want to add hosts to.
- `-version=` The version of the host set you want to add hosts to.
If you do not specify a version, the command performs a check-and-set automatically.
