Initializing Nornir¶
Easiest way of initializing nornir is with the function InitNornir.
With InitNornir
you can initialize nornir with a configuration file, with code or with a combination of both.
Let’s start with a configuration file:
[2]:
%highlight_file config.yaml
[2]:
1 --- 2 core: 3 num_workers: 100 4 5 inventory: 6 plugin: nornir.plugins.inventory.simple.SimpleInventory 7 options: 8 host_file: "inventory/hosts.yaml" 9 group_file: "inventory/groups.yaml" 10 defaults_file: "inventory/defaults.yaml"
Now to create the nornir object:
[3]:
from nornir import InitNornir
nr = InitNornir(config_file="config.yaml")
You can also initialize nornir programmatically without a configuration file:
[4]:
from nornir import InitNornir
nr = InitNornir(
core={"num_workers": 100},
inventory={
"plugin": "nornir.plugins.inventory.simple.SimpleInventory",
"options": {
"host_file": "inventory/hosts.yaml",
"group_file": "inventory/groups.yaml"
}
}
)
Or with a combination of both methods:
[5]:
from nornir import InitNornir
nr = InitNornir(core={"num_workers": 50}, config_file="config.yaml")
[6]:
nr.config.core.num_workers
[6]:
50
