Implement graceful shutdown #57

Closed alexandrebrg closed 1 year ago

alexandrebrg commented 1 year ago

What needs to be done

Wait for a SIGKILL/SIGINT signal is received to trigger graceful shutdown[^1]
Every runtime / component must have a method / capacity to kill what it has created (containers, VMs, iptables...)
Graceful shutdown should wait for all components to end their shutdown

Why it is needed

Riklet shutdown is not killing all containers / VMs created
Network management isn't deleting iptables on shutdown

Hi @kalil-pelissier, the work done on instance deletion should be helpful for you as it gives you all the necessary methods to clean up workloads (#84)!
