Launching a bare metal instance
First, select which project and site you wish to authenticate against.
[ ]:
import chi
chi.use_site('CHI@UC')
# Set to your project's charge code
chi.set('project_name', 'CH-XXXXXX')
Launch a bare metal instance.
Functions used in this example:
[ ]:
from chi.lease import get_node_reservation
from chi.server import create_server
# We assume a lease has already been created, for example with
# ``chi.lease.create_lease```
lease_name = "my_lease"
server_name = "my_server"
reservation_id = get_node_reservation(lease_name)
server = create_server(server_name, reservation_id=reservation_id)
Wait for a server’s port to come up before proceeding.
Sometimes you want to interact with the server over a remote interface and need to wait until it’s up and accepting connections. The :func:~chi.server.wait_for_tcp function allows you to do just that. This example also illustrates how you can bind a Floating IP (public IP) to the server so it can be reached over the internet.
Functions used in this example:
[ ]:
from chi.server import associate_floating_ip, wait_for_tcp
# Note: this is a placeholder server ID. Yours will be different!
# server_id can be obtained like `server.id` if you created the server
# with `create_server`. It can also be obtained via `get_server_id(name)`
server_id = "6b2bae1e-0311-493f-836c-a9da0cb9e0c0"
ip = associate_floating_ip(server_id)
# Wait for SSH connectivity over port 22
wait_for_tcp(ip, port=22)
