Health Check Hook

Feature Request

Thank you for this amazing project!

Use Case:

For https://devenv.sh I'd like to receive some kind of notification when a process is ready.

We now wrap each process using tasks, I'd like to define a task that waits until process is ready if ready probe is defined.

Maybe I can query http/socket for this?

Proposed Change:

Who Benefits From The Change(s)?

Hey @domenkozar,

Glad to hear that you find PC useful.
Can you elaborate a bit more about the use case?

Today, it is possible to poll processes status:

1. All of them at once: curl http://127.0.0.1:8080/processes | jq
2. Or one by one: curl http://127.0.0.1:8080/process/<name> | jq

Output:

{
  "name": "server",
  "namespace": "default",
  "status": "Running",
  "system_time": "59s",
  "age": 59710091487,
  "is_ready": "Ready",
  "has_ready_probe": true,
  "restarts": 0,
  "exit_code": 0,
  "pid": 8605,
  "is_elevated": false,
  "password_provided": false,
  "mem": 20185088,
  "cpu": 0.08361166938593496,
  "is_running": true
}

Or if you only care about readiness:

> curl http://127.0.0.1:8080/process/server | jq ".is_ready"
"Ready"

Are you looking for a push notification, rather than pull?
