CREATE

We can create new nodes for a simulation by using the api.nodes.create method:

sim: Simulation = api.simulations.create(name='Blank Simulation')
ubuntu_2204 = next(api.images.list(search='generic/ubuntu2204'))
node: Node = api.nodes.create(
    simulation=sim,
    image=ubuntu_2204,
    name='ubuntu-server',
)
node.dict()

Nodes can also be created off of an existing Simulation instance:

sim: Simulation = api.simulations.create(name='Blank Simulation')
ubuntu_2204 = next(api.images.list(search='generic/ubuntu2204'))
# You do not have to specify `simulation=sim` in the payload when using this method.
node: Node = sim.nodes.create(name='new-node', image=ubuntu_2204)

GET

How to list, filter, order, and search for nodes of a simulation.

ubuntu_2204: Image = next(api.images.list(search='generic/ubuntu2204'))
cumulus_5_6_0: Image = next(api.images.list(search='cumulus-vx-5.6.0'))
sim: Simulation = api.simulations.create(name='Blank Simulation')

# Create nodes with various specifications
sim.nodes.create(name='ubuntu-1', image=ubuntu_2204)
sim.nodes.create(name='ubuntu-2', image=ubuntu_2204)
sim.nodes.create(name='ubuntu-12', image=ubuntu_2204)
sim.nodes.create(name='special-node', image=ubuntu_2204)
sim.nodes.create(name='node14', image=cumulus_5_6_0)
sim.nodes.create(name='node15', image=cumulus_5_6_0)
sim.nodes.create(name='node16', image=cumulus_5_6_0)
for node in sim.nodes.list():
    print(node)

Node(id='42917bde-000a-4209-a20b-59db0c15b1a1', name='ubuntu-1')
Node(id='552b72bd-e4c5-4226-b50e-0e763c7890b8', name='ubuntu-2')
Node(id='c2903bfe-fa0b-43ec-ae75-7faf80f1f049', name='ubuntu-12')
Node(id='7f6772aa-76ef-4012-a2e0-e6d30ceb78a4', name='special-node')
Node(id='f61db084-99da-4928-bdb3-7bbd5950416e', name='node14')
Node(id='1a77d4bd-f533-48a7-a169-1415d52d8d91', name='node15')
Node(id='4abe2036-b4d1-438e-ad3b-9c236fd32e47', name='node16')

Order nodes by specific fields

for node in sim.nodes.list(ordering='name'):
    print(node.name)

node14
node15
node16
special-node
ubuntu-1
ubuntu-12
ubuntu-2

Search for nodes by name

for node in sim.nodes.list(search='node'):
    print(node.name)

node14
node15
node16

Filter node by specific properties

for node in sim.nodes.list(image=cumulus_5_6_0):
    print(node.name, node.image.name)

node14 cumulus-vx-5.6.0
node15 cumulus-vx-5.6.0
node16 cumulus-vx-5.6.0

This can be used to obtain a specific node by name

list(sim.nodes.list(name='special-node'))

[Node(id='7f6772aa-76ef-4012-a2e0-e6d30ceb78a4', name='special-node')]
