kubectl-ansible
This role contains Ansible modules that wrap kubectl/oc client CLI functionality for ease of use within Ansible playbooks and roles.
Install with:
ansible-galaxy install git+git@github.com:dgoodwin/kubectl-ansible.git,master
Exposes kubectl apply functionality to ansible. Will attempt to accurately
report changes, and supports custom resources and apiextensions.
The recommended approach for declarative management of Kubernetes config is
kubectl apply, which contains sophisticated logic for performing a three way
merge between an an objects incoming config, last applied config, and current
state. This logic however is currently implemented client side, and thus not
available to callers of the API and non-Go languages. An effort is underway (as
of April 2018) to move this logic to the Kubernetes API server itself.
For more information see:
Ansible 2.5 recently released with preview modules k8s_raw and openshift_raw. These modules however currently use a Python client library which relies on a fixed Python class existing for every API type you interact with. As such, they do not support custom resource definitions or apiextensions. An effort is underway to build a dynamic Python client which will then be integrated with these modules.
In the meantime, kubectl apply is the best tool we have available for declarative on-going Kubernetes config management. This module is intended to be a temporary solution while we wait, exposing the functionality kubectl offers and making it easy to use within Ansible. It's interface is as consistent as possible with k8s_raw to help with eventually transitioning, and when the above work completes this module can likely be abandoned.
Exposes oc process functionality for processing OpenShift templates. Result can then be created/applied with kubectl_apply or k8s_raw.
kubectl/oc binaries installed on the target system.
