Launch guide for netSender

1. Run in the netSender example directory:

   go build

   The result is executable file "netSender"

2. Run our gVisor. Note that you need config with runtime-socket option

   Our init_script.sh runs /bin/bash inside the gVisor

3. Get to the netSender example directory

4. Run

   ./netSender

   Every second you will see

   Response body: {"activity":"Learn a new programming language","type":"education","participants":1,"price":0.1,"link":"","key":"5881028","accessibility":0.25}
   

5. Switch to another terminal

6. Configure sandbox-cli to use the same host and port as gVisor

7. To add the hooks into gVisor run

   ./sandbox-cli state -c Sandbox/examples/gWisord/netSender/hooks.js

   If the script is correct you will see the message:

   Type: ok
   gVisor says: Everything ok
   Payload: {}
   

8. After this you will see that netSender behaviour is changed. Now it will be printing:

   Response body: {"error":"No activity found with the specified parameters"}
