Installed linkerd stable-2.13.5 in an air gapped environment. Copied all the images based on yaml. The check after installation of linkerd is fine. But when trying to install viz plugin, all deployments - metrics-api, prometheus, tap, tap-injector and web - throwing error as below:

Error creating: Pod “metrics-api-2323ksadsa0asdfas” is invalid: [spec.initcontainers[0].name: Required value]

The cluster is running in Kubernetes v1.21.

Any one got such errors previously and any pointers for the fix?

Thanks in advance.

Before installing linkerd-viz, did you wait for the linkerd core control plane to become ready? The linkerd-proxy-injector in particular needs to be ready in order to inject the linkerd-init initContainer and linkerd-proxy container when the viz workloads are deployed. Can you share the metrics-api pod yaml to see what could be going on?

Yes…all the four deployments in linkerd namespace were up.

The viz yml used to create the workloads is [here](https://drive.google.com/file/d/1nj8hvRR_nSreoqKhf3KukEXPVulqEiuM/view?usp=drive_link)

That yaml seems fine, and applying it on a cluster with a healthy linkerd instance brings up viz fine…  
Can you share the yaml of the actual metrics-api pod, not its deployment?

The POD keep crashing and i am not able to describe the POD to get the yaml. I just added some zipkin as an init container but now complaining as spec.initcontainers[1].name: Required value. Not sure how this list of arrays and validations are coming up.
