Note

This plugin is part of the community.okd collection (version 1.0.1).

To install it use: ansible-galaxy collection install community.okd.

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

New in version 0.3.0: of community.okd

Synopsis

  • Processes a specified OpenShift template with the provided template.
  • Templates can be provided inline, from a file, or specified by name and namespace in the cluster.
  • Analogous to oc process.
  • For CRUD operations on Template resources themselves, see the community.okd.k8s module.

Requirements

The below requirements are needed on the host that executes this module.

  • python >= 2.7
  • openshift >= 0.11.0
  • PyYAML >= 3.11

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.
host
string
Provide a URL for accessing the API. Can also be specified via K8S_AUTH_HOST environment variable.
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.
name
string
The name of the Template to process.
The Template must be present in the cluster.
When provided, namespace is required.
Mutually exclusive with resource_definition or src
namespace
string
The namespace that the template can be found in.
namespace_target
string
The namespace that resources should be created, updated, or deleted in.
Only used when state is present or absent.
parameter_file
string
A path to a file containing template parameter values to override/set values in the Template.
Corresponds to the `--param-file` argument to oc process.
parameters
dictionary
A set of key: value pairs that will be used to set/override values in the Template.
Corresponds to the `--param` argument to oc process.
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.
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
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).
resource_definition
string
Provide a valid YAML definition (either as a string, list, or dict) for an object when creating or updating.
NOTE: kind, api_version, name, and namespace will be overwritten by corresponding values found in the provided resource_definition.

aliases: definition, inline
src
path
Provide a path to a file containing a valid YAML definition of an object or objects to be created or updated. Mutually exclusive with resource_definition. NOTE: kind, api_version, name, and namespace will be overwritten by corresponding values found in the configuration read in from the src file.
Reads from the local file system. To read from the Ansible controller's file system, including vaulted files, use the file lookup plugin or template lookup plugin, combined with the from_yaml filter, and pass the result to resource_definition. See Examples below.
Mutually exclusive with template in case of k8s module.
state
string
    Choices:
  • absent
  • present
  • rendered
Determines what to do with the rendered Template.
The state rendered will render the Template based on the provided parameters, and return the rendered objects in the resources field. These can then be referenced in future tasks.
The state present will cause the resources in the rendered Template to be created if they do not already exist, and patched if they do.
The state absent will delete the resources in the rendered Template.
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.

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.
