This message is similar to IST0105, which is a warning message for a single pod.
This message occurs when the namespace is enabled for automatic sidecar injection, but some pods in the namespace are not having the correct sidecar injected.
If any of the pods in the namespace are not running the correct sidecar version, this message will be reported. The names of the pods are listed in the message detail.
This often happens as a result of upgrading the Istio control plane; after upgrading Istio (which includes the sidecar injector), all running workloads with an Istio sidecar must be recreated to allow the new version of the sidecar to be injected.
To resolve this problem, update the sidecar version by redeploying your applications using your normal rollout strategy. For a Kubernetes deployment:
- If you’re using Kubernetes 1.15 or higher, you can run
kubectl rollout restart <my-deployment>to trigger a new rollout.
- Alternatively, you can modify the deployment’s
templatefield to force a new rollout. This is often done by adding a label like
force-redeploy=<current-timestamp>to the pod definition in the template.
