Hello everyone. I’ve used Tower for a long while now, on a daily basis, but I’m pretty new to installing an AWX instance in my kubernetes cluster. (For testing purposes). So, I’ve setup 2 Centos 8, installed and configured a 2 node kubernetes cluster, and then tried to install AWX through the AWX\_Operator. In the past, I’ve successfully installed a trial version of ansible tower seamlessly, but AWX is giving me some headaches. So, here’s what I’m doing: As per AWX\_Operator installation guide ([https://github.com/ansible/awx-operator/blob/devel/README.md](https://github.com/ansible/awx-operator/blob/devel/README.md)), I’ve ran the following: #\> kubectl apply -f [https://raw.githubusercontent.com/ansible/awx-operator/0.8.0/deploy/awx-operator.yaml](https://raw.githubusercontent.com/ansible/awx-operator/0.8.0/deploy/awx-operator.yaml) I had my awx-operator-xxxxx pod created. then I create a my-awx.yml file with the following: — apiVersion: [awx.ansible.com/v1beta1](http://awx.ansible.com/v1beta1) kind: AWX metadata: name: awx Then I run kubectl apply -f my-awx.yml After a short while, I can see the services created, but awx-postgres-0 in a pending state. When I describe the pod, I can see that it’s not being able to create its storage: default-scheduler 0/2 nodes are available: 2 pod has unbound immediate PersistentVolumeClaims. Could someone let me know why I’m experiencing this error? I’m pretty new to k8s and I’ve googled around and tried dozens of things, but couldn’t find how to solve it. Thank you. Ariel. ---

Yes. What’s happening is thst it can’t find storage for your pod. In kubernetes a deployment will request for storage through a persistent volume claim otherwise called a pvc. You have to provide that storage with a persistrnt volume or a pv ---
