OpenShift - List Cluster Operators using Python

Updated:   |  OpenShift articles

The openshift package can be used to interact with OpenShift in Python. pip install can be used to install the OpenShift package.

pip install openshift

 

You may want to first check out my article FreeKB - OpenShift - Login into OpenShift using Python.

And here is an example of how you could log into OpenShift with a username and password and list all Cluster Operators.

from kubernetes import client
from openshift.dynamic import DynamicClient
from openshift.helper.userpassauth import OCPLoginConfiguration

apihost  = 'https://api.openshift.example.com:6443'
username = 'john.doe'
password = 'itsasecret'

kubeConfig = OCPLoginConfiguration(ocp_username=username, ocp_password=password)
kubeConfig.host = apihost
kubeConfig.verify_ssl = False
kubeConfig.get_token()

k8s_client = client.ApiClient(kubeConfig)
dyn_client = DynamicClient(k8s_client)

response = dyn_client.resources.get(api_version='config.openshift.io/v1', kind='ClusterOperator')
data = response.get()

for item in data.items:
  print(item)

 

Here is a bit more of a practical example with try / except / else error handling.

import sys
from kubernetes import client
from openshift.dynamic import DynamicClient
from openshift.helper.userpassauth import OCPLoginConfiguration

apihost  = 'https://api.openshift.example.com:6443'
username = 'john.doe'
password = 'itsasecret'

kubeConfig = OCPLoginConfiguration(ocp_username=username, ocp_password=password)
kubeConfig.host = apihost
kubeConfig.verify_ssl = False
kubeConfig.get_token()

k8s_client = client.ApiClient(kubeConfig)
dyn_client = DynamicClient(k8s_client)

try:
  response = dyn_client.resources.get(api_version='config.openshift.io/v1', kind='ClusterOperator')
except ApiException as exception:
  print(f"got the following exception - {exception}")
  sys.exit(1)
  
response = dyn_client.resources.get(api_version='config.openshift.io/v1', kind='ClusterOperator')
data = response.get()

for item in data.items:
  print(item)

 

And here is now you could list a specific Cluster Operator.

data = response.get(name='storage')

 

And here is how you can print a specific key in the response using dot notation.

data = response.get(name='storage')
print(data.metadata.name)

 

Or like this.

data = response.get(name='storage')
print(data['metadata']['name'])
