Parameters

Parameter Choices/Defaults Comments
api_key
string
Token used to authenticate with the API. Can also be specified via K8S_AUTH_API_KEY environment variable.
ca_cert
path
Path to a CA certificate used to authenticate with the API. The full certificate chain must be provided to avoid certificate validation errors. Can also be specified via K8S_AUTH_SSL_CA_CERT environment variable.

aliases: ssl_ca_cert
client_cert
path
Path to a certificate used to authenticate with the API. Can also be specified via K8S_AUTH_CERT_FILE environment variable.

aliases: cert_file
client_key
path
Path to a key file used to authenticate with the API. Can also be specified via K8S_AUTH_KEY_FILE environment variable.

aliases: key_file
context
string
The name of a context found in the config file. Can also be specified via K8S_AUTH_CONTEXT environment variable.
force
boolean
    Choices:
  • no ←
  • yes
If set to yes, and state is present, an existing object will be replaced.
host
string
Provide a URL for accessing the API. Can also be specified via K8S_AUTH_HOST environment variable.
hostname
string
The hostname for the Route.
kubeconfig
path
Path to an existing Kubernetes config file. If not provided, and no other connection options are provided, the openshift client will attempt to load the default configuration file from ~/.kube/config.json. Can also be specified via K8S_AUTH_KUBECONFIG environment variable.
labels
dictionary
Specify the labels to apply to the created Route.
A set of key: value pairs.
name
string
The desired name of the Route to be created.
Defaults to the value of service
namespace
string / required
The namespace of the resource being targeted.
The Route will be created in this namespace as well.
password
string
Provide a password for authenticating with the API. Can also be specified via K8S_AUTH_PASSWORD environment variable.
Please read the description of the username option for a discussion of when this option is applicable.
path
string
The path for the Route
persist_config
boolean
    Choices:
  • no
  • yes
Whether or not to save the kube config refresh tokens. Can also be specified via K8S_AUTH_PERSIST_CONFIG environment variable.
When the k8s context is using a user credentials with refresh tokens (like oidc or gke/gcloud auth), the token is refreshed by the k8s python client library but not saved by default. So the old refresh token can expire and the next auth might fail. Setting this flag to true will tell the k8s python client to save the new refresh token to the kube config file.
Default to false.
Please note that the current version of the k8s python client library does not support setting this flag to True yet.
The fix for this k8s python library is here: https://github.com/kubernetes-client/python-base/pull/169
port
string
Name or number of the port the Route will route traffic to.
proxy
string
The URL of an HTTP proxy to use for the connection. Can also be specified via K8S_AUTH_PROXY environment variable.
Please note that this module does not pick up typical proxy settings from the environment (e.g. HTTP_PROXY).
service
string
The name of the service to expose.
Required when state is not absent.

aliases: svc
state
string
    Choices:
  • absent
  • present ←
Determines if an object should be created, patched, or deleted. When set to present, an object will be created, if it does not already exist. If set to absent, an existing object will be deleted. If set to present, an existing object will be patched, if its attributes differ from those specified using resource_definition or src.
termination
string
    Choices:
  • edge
  • passthrough
  • reencrypt
  • insecure ←
The termination type of the Route.
If left empty no termination type will be set, and the route will be insecure.
When set to insecure tls will be ignored.
tls
dictionary
TLS configuration for the newly created route.
Only used when termination is set.
ca_certificate
string
Path to a CA certificate file on the target host.
Not supported when termination is set to passthrough.
certificate
string
Path to a certificate file on the target host.
Not supported when termination is set to passthrough.
destination_ca_certificate
string
Path to a CA certificate file used for securing the connection.
Only used when termination is set to reencrypt.
Defaults to the Service CA.
insecure_policy
string
    Choices:
  • allow
  • redirect
  • disallow ←
Sets the InsecureEdgeTerminationPolicy for the Route.
Not supported when termination is set to reencrypt.
When termination is set to passthrough, only redirect is supported.
If not provided, insecure traffic will be disallowed.
key
string
Path to a key file on the target host.
Not supported when termination is set to passthrough.
username
string
Provide a username for authenticating with the API. Can also be specified via K8S_AUTH_USERNAME environment variable.
Please note that this only works with clusters configured to use HTTP Basic Auth. If your cluster has a different form of authentication (e.g. OAuth2 in OpenShift), this option will not work as expected and you should look into the k8s_auth module, as that might do what you need.
validate_certs
boolean
    Choices:
  • no
  • yes
Whether or not to verify the API server's SSL certificates. Can also be specified via K8S_AUTH_VERIFY_SSL environment variable.

aliases: verify_ssl
wait
boolean
    Choices:
  • no ←
  • yes
Whether to wait for certain resource kinds to end up in the desired state.
By default the module exits once Kubernetes has received the request.
Implemented for state=present for Deployment, DaemonSet and Pod, and for state=absent for all resource kinds.
For resource kinds without an implementation, wait returns immediately unless wait_condition is set.
wait_condition
dictionary
Specifies a custom condition on the status to wait for.
Ignored if wait is not set or is set to False.
reason
string
The value of the reason field in your desired condition
For example, if a Deployment is paused, The Progressing type will have the DeploymentPaused reason.
The possible reasons in a condition are specific to each resource type in Kubernetes.
See the API documentation of the status field for a given resource to see possible choices.
status
string
    Choices:
  • True ←
  • False
  • Unknown
The value of the status field in your desired condition.
For example, if a Deployment is paused, the Progressing type will have the Unknown status.
type
string
The type of condition to wait for.
For example, the Pod resource will set the Ready condition (among others).
Required if you are specifying a wait_condition.
If left empty, the wait_condition field will be ignored.
The possible types for a condition are specific to each resource type in Kubernetes.
See the API documentation of the status field for a given resource to see possible choices.
wait_sleep
integer
Default:
5
Number of seconds to sleep between checks.
wait_timeout
integer
Default:
120
How long in seconds to wait for the resource to end up in the desired state.
Ignored if wait is not set.
wildcard_policy
string
    Choices:
  • Subdomain
The wildcard policy for the hostname.
Currently only Subdomain is supported.
If not provided, the default of None will be used.

Notes

Note

  • The OpenShift Python client wraps the K8s Python client, providing full access to all of the APIS and models available on both platforms. For API version details and additional information visit https://github.com/openshift/openshift-restclient-python

  • To avoid SSL certificate validation errors when validate_certs is True, the full certificate chain for the API server must be provided via ca_cert or in the kubeconfig file.
