## Synopsis

- Use Openshift Python SDK to manage Services on Kubernetes

## Requirements

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

- python >= 2.7
- openshift >= 0.6.2

## 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 `True`, 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.
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.

merge_type
list

Choices:
- json
- merge
- strategic-merge

Whether to override the default patch merge approach with a specific type. By default, the strategic merge will typically be used.
For example, Custom Resource Definitions typically aren't updatable by the usual strategic merge. You may want to use `merge` if you see "strategic merge patch format is not supported"
See https://kubernetes.io/docs/tasks/run-application/update-api-object-kubectl-patch/#use-a-json-merge-patch-to-update-a-deployment
Requires openshift >= 0.6.2
If more than one merge_type is given, the merge_types will be tried in order
If openshift >= 0.6.2, this defaults to `['strategic-merge', 'merge']`, which is ideal for using the same parameters on resource kinds that combine Custom Resources and built-in resources. For openshift < 0.6.2, the default is simply `strategic-merge`.

name string / required |  | Use to specify a Service object name.
namespace string / required |  | Use to specify a Service object namespace.
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.
ports list |  | A list of ports to expose. https://kubernetes.io/docs/concepts/services-networking/service/#multi-port-services
proxy - added in 2.9 |  | 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
dictionary

A partial YAML definition of the Service object being created/updated. Here you can define Kubernetes Service Resource parameters not covered by this module's parameters.
NOTE: resource_definition has lower priority than module parameters. If you try to define e.g. metadata.namespace here, that value will be ignored and metadata used instead.
aliases: definition, inline

selector dictionary |  | Label selectors identify objects this Service should apply to. https://kubernetes.io/docs/concepts/overview/working-with-objects/labels/

state
-

Choices:
- present ←
- absent

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 module options and resource_definition.

type
-

Choices:
- NodePort
- ClusterIP
- LoadBalancer
- ExternalName

Specifies the type of Service to create.
See https://kubernetes.io/docs/concepts/services-networking/service/#publishing-services-service-types

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

## 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.

## Examples

    - name: Expose https port with ClusterIP
      k8s_service:
        state: present
        name: test-https
        namespace: default
        ports:
        - port: 443
          protocol: TCP
        selector:
          key: special

    - name: Expose https port with ClusterIP using spec
      k8s_service:
        state: present
        name: test-https
        namespace: default
        inline:
          spec:
            ports:
            - port: 443
              protocol: TCP
            selector:
              key: special

## Return Values

Common return values are documented here, the following are the fields unique to this module:

Key | Returned | Description
--- | --- | ---
result complex | success | The created, patched, or otherwise present Service object. Will be empty in the case of a deletion.
| api_version string | success | The versioned schema of this representation of an object.
| kind string | success | Always 'Service'.
| metadata complex | success | Standard object metadata. Includes name, namespace, annotations, labels, etc.
| spec complex | success | Specific attributes of the object. Will vary based on the api_version and kind.
| status complex | success | Current status details for the object.

## Status

- This module is not guaranteed to have a backwards compatible interface. [preview]
- This module is maintained by the Ansible Community. [community]
