### Interaction with Cocos microservice
If the [cocos](https://github.com/ultravioletrs/cocos) is running, you can use `cocos` to send computation request to the `agent` via gRPC.
NB: you need to run `cocos` `computations` microservice with `COCOS_COMPUTATIONS_AGENT_GRPC_URL=192.168.122.251:7002`, i.e. with the correct address and port of the agent gRPC client running in the VM.
Create computation with
```sh
curl -sSi -X POST http://localhost:9000/computations -H "Content-Type: application/json" -d @- <<EOF
{
"name": "computation_24",
"description": "this_computes_the_number_24",

Note the computation id in the `Location` header. Set the environmnet variable `COMPUTATION_ID=9429a679-173e-4c2d-856f-74c92e08ab76` and run it with
```sh
curl -sSi -X POST http://localhost:9000/computations/$COMPUTATION_ID/run
