Practical Ansible 2

Creating a Kubernetes Service with Ansible

So far, we have seen how to create namespaces from Ansible, so now, let's put a Service in the namespace we just created. Let's create a new playbook called k8s-svc.yaml with the following content:

---- hosts: localhost  tasks:    - name: Ensure the Service mysvc is present      k8s:        state: present        definition:          apiVersion: v1          kind: Service          metadata:            name: mysvc            namespace: myns          spec:            selector:              app: myapp              service: mysvc            ports:              - protocol: TCP                targetPort: 800                name: port-80-tcp                port: 80

Before running it, we can execute kubectl get svc to ensure that the namespace has no Services. Make sure you're in the right namespace before running it! In my case, the output is as follows:

$ kubectl get svcNo resources found ...
