Reporter: Tiago Reis
When connecting to a Google Kubernetes Engine, a command {{gcloud container
clusters get-credentials}} is used that generates a {{~/.kube/config}} file.
The distinctive trait in this config file is that it uses an {{auth-provider}}
relying on {{gcloud}} to inject the keys {{expiry}} and {{access-token}} from
the general Google SDK auth config, as seen here:
{code:json}
users:
- name: gke_my-project_my-region_my-cluster
user:
auth-provider:
config:
cmd-args: config config-helper --format=json
cmd-path: /Users/reist01/google-cloud-sdk/bin/gcloud
expiry-key: '{.credential.token_expiry}'
token-key: '{.credential.access_token}'
{code}
{{kubectl}}, because it uses {{client-go}}, supports the auth-provider and
fetches the token and expiry from the json returne by config-helper. As Spark
is using the fabric8 client, this is yet to be supported, breaking when running
spark-submit:
{code:java}
Exception in thread "main"
io.fabric8.kubernetes.client.KubernetesClientException: Failure executing: POST
at: https://my-endpoint/api/v1/namespaces/my-namespace/pods. Message:
Forbidden! User gke_my-project_my-region_my-cluster doesn't have permission.
pods is forbidden: User "system:anonymous" cannot create resource "pods" in API
group "" in the namespace "my-namespace".
