```
Define Type of runner
```bash
./dispatcher-linux --wss wss://my-graphql-server/subscriptions --runner-type runner
```

```
### Subscriptions query which this machine is subscribed
```graphql
subscription($machineHash: String!) {
registerInstance(machineHash: $machineHash) {
command
args
}
}
```

@Type(
new GraphQLObjectType({
name: 'InstanceConnectionType',
fields: {
command: {
type: GraphQLInt,
},
args: {
type: GraphQLString,
},
},
}),
)
@Subscribe(
withFilter(
(self: InstanceController) =>
self.pubsub.asyncIterator(InstanceCommandsChannel),
async (event: InstanceEventType, unk, args: InstanceEventType) => {
if (args.machineHash === event.machineHash) {
console.log(
`
[RegisterInstance]
NetworkInterfaces:
MachineHash: "${args.machineHash}"
Event: "instance-notification"
Command: ${InstanceCommandsEnum[event.command]}
Arguments: ${event.args}
[RegisterInstance]
`,
);
}
return args.machineHash === event.machineHash;
},
),
)
@Subscription({
machineHash: {
type: new GraphQLNonNull(GraphQLString),
},
})
registerInstance(event: InstanceEventType) {
return event;
}
```
