gridscale Compute Driver Documentation¶

gridscale is a German cloud provider with focus on awesome user experience.

Instantiating a driver¶

The gridscale driver requires your User_Uuid and your API-Token. You will have to generate a API-Token first, to be able to do that, you want to make an account and create a token under the API-Key option in the panel.

from libcloud.compute.providers import get_driver
from libcloud.compute.type import Provider

driver = get_driver(Provider.GRIDSCALE)

driver = driver("USER-UUID", "API-TOKEN")

Creating a Server¶

from libcloud.compute.providers import get_driver
from libcloud.compute.base import NodeSize
from libcloud.compute.type import Provider

cls = get_driver(Provider.GRIDSCALE)
driver = cls("USER-UUID", "API-TOKEN")

# We don't feature packages containing a fix size so you will have to
# built your own size object. Make sure to use a multiple of 1024MB when
# asigning RAM
size_name = "my-node-size"
ram = 1024  # amout of ram In MB
disk = 10  # disk size in GB
cores = 1  # numer of cores node should have
size = NodeSize(
    id=0,
    bandwidth=0,
    price=0,
    name=size_name,
    ram=ram,
    disk=disk,
    driver=driver,
    extra={"cores": cores},
)

ssh_key = driver.list_key_pairs()[0]
ssh_key_uuid = ssh_key.fingerprint

node_name = "MyServer"

images = driver.list_images()
image = [i for i in images if i.name == "Ubuntu 18.04 LTS"][0]

locations = driver.list_locations()
location = [loc for loc in locations if loc.name == "de/fra"][0]

node = driver.create_node(
    name=node_name, size=size, image=image, location=location, ex_ssh_key_ids=ssh_key
)

deploy_node(deploy, ssh_username='root', ssh_alternate_usernames=None, ssh_port=22, ssh_timeout=10, ssh_key=None, ssh_key_password=None, auth=None, timeout=300, max_tries=3, ssh_interface='public_ips', at_exit_func=None, wait_period=5, **create_node_kwargs)¶

Create a new node, and start deployment.

In order to be able to SSH into a created node access credentials are required.

A user can pass either a NodeAuthPassword or NodeAuthSSHKey to the auth argument. If the create_node implementation supports that kind if credential (as declared in self.features['create_node']) then it is passed on to create_node. Otherwise it is not passed on to create_node and it is only used for authentication.

If the auth parameter is not supplied but the driver declares it supports generates_password then the password returned by create_node will be used to SSH into the server.

Finally, if the ssh_key_file is supplied that key will be used to SSH into the server.

This function may raise a DeploymentException, if a create_node call was successful, but there is a later error (like SSH failing or timing out). This exception includes a Node object which you may want to destroy if incomplete deployments are not desirable.

>>> from libcloud.compute.drivers.dummy import DummyNodeDriver
>>> from libcloud.compute.deployment import ScriptDeployment
>>> from libcloud.compute.deployment import MultiStepDeployment
>>> from libcloud.compute.base import NodeAuthSSHKey
>>> driver = DummyNodeDriver(0)
>>> key = NodeAuthSSHKey('...') # read from file
>>> script = ScriptDeployment("yum -y install emacs strace tcpdump")
>>> msd = MultiStepDeployment([key, script])
>>> def d():
...     try:
...         driver.deploy_node(deploy=msd)
...     except NotImplementedError:
...         print ("not implemented for dummy driver")
>>> d()
not implemented for dummy driver

Deploy node is typically not overridden in subclasses. The existing implementation should be able to handle most such.

Parameters

deploy (Deployment) – Deployment to run once machine is online and available to SSH.
ssh_username (str) – Optional name of the account which is used when connecting to SSH server (default is root)
ssh_alternate_usernames (list) – Optional list of ssh usernames to try to connect with if using the default one fails

auth (NodeAuthSSHKey or NodeAuthPassword) – Initial authentication information for the node (optional)
ssh_key (str or list of str) – A path (or paths) to an SSH private key with which to attempt to authenticate. (optional)
ssh_key_password (str) – Optional password used for encrypted keys.
timeout (int) – How many seconds to wait before timing out. (default is 600)

Keep in mind that this function will only be called in such scenario. In case the method finishes (this includes throwing an exception), at exit handler function won’t be called.
