Selector is for choosing remotes to interact with. Currently, HapiDeploy only supports selecting remotes by their labels.

Usage

For example, the inventory.yaml file defines 3 remotes like this.

remotes:
  server-1:
    host: 192.168.33.11
  server-2:
    host: 192.168.33.12
  server-3:
    host: 192.168.33.13

The deploy.py file defines a task called ping like this.

from hapi import Context
from hapi.cli import app

@app.task(name="ping", desc="Check SSH connection")
def ping(c: Context):
    c.run("whoami")

Run hapi ping or hapi ping all will execute the ping task on all remotes.

hapi ping

hapi ping all

The default selector is "all".

If you want to run the ping task against the server-1 only, you have to specify it. It's similar to server-2 and server-3.

hapi ping server-1
hapi ping server-2
hapi ping server-3
