Oracle Cloud cluster

[alekitto]

Hi everyone,
Thanks for your work on this project!

Is it possible to add a cluster deployed on Oracle Cloud? Does it need a completely new authentication mechanism or can be added through one of the already implemented ones?

Hi @alekitto, sorry I'm not very familiar with Oracle Cloud. If I get it right from the documentation they are using sth. like the following for the authentication right?

user:
  exec:
    apiVersion: client.authentication.k8s.io/v1beta1
    args:
    - ce
    - cluster
    - generate-token
    - --cluster-id
    - <cluster ocid>
    - --profile
    - <profile-name>
    command: oci
    env: []

If this is the case we would have to implement a new provider for it.

Hi @ricoberger!
Correct! With some guidance I can try to implement a new provider myself if it's ok, I just need a starting point (ex: a similar provider to see how it is working).

That would be awesome, I think a good starting point could be the Azure Provider, which is implemented in the following files:

• This file is used to fetch the clusters and Kubeconfig via the provided Azure credentials: https://github.com/kubenav/kubenav/blob/main/cmd/mobile/azure.go
• In this file a user can provide the credentials for Azure: https://github.com/kubenav/kubenav/blob/main/lib/widgets/settings/providers/settings_azure_provider_config.dart
• The clusters which should be added are shown via the following file https://github.com/kubenav/kubenav/blob/main/lib/widgets/settings/clusters/settings_add_cluster_azure.dart
• Service to interact with the Go code: https://github.com/kubenav/kubenav/blob/main/lib/services/providers/azure_service.dart

Another good example is the GCP plugin, when no Go code is required to get the clusters / access token:

• Configuration for the provider: https://github.com/kubenav/kubenav/blob/main/lib/widgets/settings/providers/settings_google_provider_config.dart
• Adding the clusters to the app: https://github.com/kubenav/kubenav/blob/main/lib/widgets/settings/clusters/settings_add_cluster_google.dart
• Service to interact with the Google API: https://github.com/kubenav/kubenav/blob/main/lib/services/providers/google_service.dart
• The code to refresh the access token provided by Google:

  kubenav/lib/repositories/clusters_repository.dart

  Line 330 in a7addb2

  } else if (cluster.clusterProviderType == ClusterProviderType.google) {

To store the provider configuration the following file must be adjusted https://github.com/kubenav/kubenav/blob/main/lib/models/cluster_provider.dart

I can also assist with the implementation or take over some parts. Since I'm not familiar with Oracle the following points would be good to know:

• Which information must be provided by a user
• Which API endpoints can be used to get the credentials and clusters based on the provided user information

You can add a serviceaccount and add it to your kubeconfig. Details described here..
This works fine with kubenav :)
