To use it in a playbook, specify: community.okd.openshift_route.

New in version 0.3.0: of community.okd

Synopsis

  • Looks up a Service and creates a new Route based on it.

  • Analogous to oc expose and oc create route for creating Routes, but does not support creating Services.

  • For creating Services from other resources, see kubernetes.core.k8s.

force

boolean

If set to yes, and state is present, an existing object will be replaced.

Choices:

  • no ← (default)

  • yes

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.

impersonate_groups

list / elements=string

added in 2.3.0 of kubernetes.core

Group(s) to impersonate for the operation.

Can also be specified via K8S_AUTH_IMPERSONATE_GROUPS environment. Example: Group1,Group2

impersonate_user

string

added in 2.3.0 of kubernetes.core

Username to impersonate for the operation.

Can also be specified via K8S_AUTH_IMPERSONATE_USER environment.

kubeconfig

raw

Path to an existing Kubernetes config file. If not provided, and no other connection options are provided, the Kubernetes client will attempt to load the default configuration file from ~/.kube/config. Can also be specified via K8S_AUTH_KUBECONFIG environment variable.

The kubernetes configuration can be provided as dictionary. This feature requires a python kubernetes client version >= 17.17.0. Added in version 2.2.0.

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.

no_proxy

string

added in 2.3.0 of kubernetes.core

The comma separated list of hosts/domains/IP/CIDR that shouldn’t go through proxy. Can also be specified via K8S_AUTH_NO_PROXY environment variable.

Please note that this module does not pick up typical proxy settings from the environment (e.g. NO_PROXY).

This feature requires kubernetes>=19.15.0. When kubernetes library is less than 19.15.0, it fails even no_proxy set in correct.

example value is “localhost,.local,.example.com,127.0.0.1,127.0.0.0/8,10.0.0.0/8,172.16.0.0/12,192.168.0.0/16”

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

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

Choices:

  • no

  • yes

port

string

Name or number of the port the Route will route traffic to.

proxy

string

string

Colon-separated username:password for basic authentication header.

Can also be specified via K8S_AUTH_PROXY_HEADERS_BASIC_AUTH environment.

proxy_basic_auth

string

Colon-separated username:password for proxy basic authentication header.

Can also be specified via K8S_AUTH_PROXY_HEADERS_PROXY_BASIC_AUTH environment.

Can also be specified via K8S_AUTH_PROXY_HEADERS_USER_AGENT environment.

service

aliases: svc

string

The name of the service to expose.

Required when state is not absent.

state

string

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.

Choices:

  • absent

  • present ← (default)

termination

string

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.

Choices:

  • edge

  • passthrough

  • reencrypt

  • insecure ← (default)

tls

dictionary

TLS configuration for the newly created route.

Only used when termination is set.

ca_certificate

string

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

  • disallow ← (default)

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 community.okd.k8s_auth module, as that might do what you need.

validate_certs

aliases: verify_ssl

boolean

Whether or not to verify the API server’s SSL certificates. Can also be specified via K8S_AUTH_VERIFY_SSL environment variable.

Choices:

  • no

  • yes

wait

boolean

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.

Choices:

  • no ← (default)

  • yes

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

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.

Choices:

  • True ← (default)

  • False

  • Unknown

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

Number of seconds to sleep between checks.

Default: 5

wait_timeout

integer

How long in seconds to wait for the resource to end up in the desired state.

Ignored if wait is not set.

Default: 120

wildcard_policy

string

The wildcard policy for the hostname.

Currently only Subdomain is supported.

If not provided, the default of None will be used.

Choices:

  • Subdomain

Notes

Note

  • 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.
