How to create a new namespace in a project using this client?

[JeffreyDD]

I'm trying to create a namespace inside a project, but have not been able to find the proper method to do so. I have been able to create projects, apply actions, but I can't seem to find any way to create a namespace, either as an action on a project or cluster, nor using client.create.

I'm using the master branch of this client with rancher API version 3

Some of the things I've tried so far:

rancher_namespace = self.rancher_client.create(type='namespace', clusterId=rancher_cluster.id, projectId=rancher_project.id, name=name)
# KeyError: 'namespace'

rancher_cluster = self.rancher_client.by_id_cluster(rancher_project.clusterId);
rancher_namespace = rancher_cluster.namespaces().create()

rancher_namespace = self.rancher_client.create_namespace()

I've noticed that namespaces are managed as a subresource of clusters, and are accessible through the API as such (rancher_namespace = self.rancher_client.), but how can I get these through this client? I've read through the source code and can't seem to find any way to accomplish this, can someone maybe point me in the right direction?

Hi @JeffreyDD ,

I see that it isn't very straight forward to create a namespace with this client, but figured out a way to do this by 'abusing' the _post function of the client (directly posting to the Rancher API trough the client).

I have found that the create function, which is only available at the root, has access to some sort of types schema:

client-python/rancher.py

Lines 433 to 435 in c357e7a

	def create(self, type, *args, **kw):
	collection_url = self.schema.types[type].links.collection
	return self._post(collection_url, data=self._to_dict(*args, **kw))

(for a complete list of types, try piece of python: [ type for type in client.schema.types ] )

You would expect namespace to be one of them, but unfortunately this isn't the case. These types are not part of this client, but are provided by the rancher API (thus if desired to have it available an issue at Rancher itself should be filed).

However, in that same block you see how the Post method is build up, to get an understanding of what information could be provided as data you can explore the API trough the Rancher GUI (e.g. https:///v3/cluster//namespaces --> Create Operation).

I came up with the following:

cluster = client.by_id_cluster('c-6lhz6')
namespaces=cluster.namespaces()
client._post(namespaces.createTypes[namespaces.resourceType],data={'name':'new','projectId':'c-6lhz6:p-xvqq2'})

That created a namespace named 'new' in my 'default' project, whereas off-course the id's will differ in your case.

It looks like this is answered so going to close this issue, if not feel free to reopen

Based on what @rule88 said, I´ve found this:

client2 = rancher.Client(url='<<your_server_URL>>/v3/cluster/<<CLUSTER_ID>, access_key=access_key, secret_key=secret_key)

client2.create_namespace(name="NAMESPACE_NAME" projectId="CLUSTER_ID:PROJECT_ID")

The trick is connect the client to the right api url, on which the namespace object type exists

Hope this help others like me trying to use the python client.
