Kubernetes Deployment implementation guide Pods with New Image Tag - ImagePullBackOff scenarios
I'm confused about I'm working with an scenario with my Kubernetes deployment not updating the pods to use a new image tag. I have a deployment configured with image `myapp:latest` and I've recently pushed a new version of my application with the tag `myapp:v2.0`. However, after updating the deployment with the new image tag, my pods are exploring in `ImagePullBackOff` status. I’ve tried running `kubectl rollout restart deployment/my-deployment` to trigger an update, but the scenario continues. Here’s the deployment YAML I’m using: ```yaml apiVersion: apps/v1 kind: Deployment metadata: name: my-deployment spec: replicas: 3 selector: matchLabels: app: myapp template: metadata: labels: app: myapp spec: containers: - name: myapp image: myapp:v2.0 ports: - containerPort: 8080 ``` I’ve checked the image repository and confirmed that `myapp:v2.0` exists. I also verified that my deployment is properly set up for pulling images from the private registry by ensuring that the necessary image pull secrets are in place. Here’s the relevant secret configuration: ```yaml apiVersion: v1 kind: Secret metadata: name: my-registry-secret type: kubernetes.io/dockerconfigjson data: .dockerconfigjson: <base64-encoded-dockerconfigjson> ``` I added this secret to the service account used by the deployment, but still, the new pods remain in `ImagePullBackOff`. The behavior message indicates that Kubernetes want to pull the image, but I can pull it manually using `docker pull myapp:v2.0` from my local machine. I've also verified that the Kubernetes nodes have access to the internet. Has anyone encountered a similar scenario or can provide insight into what might be going wrong? Is this even possible?
