No it is not. It's not apparent to me why you are seeing that. can you strace or equiv of that and see where the call is coming from?

[sunilkcs]

The problem is resolved after deleing '/.docker/config.json' file in home directory. It had entries like below. I deleted this file completely. After that podman is working fine.

{
"auths": {
"https://index.docker.io/v1/": {}
},
"credHelpers": {
"gcr.io": "gcloud",
"us.gcr.io": "gcloud",
"eu.gcr.io": "gcloud",
"asia.gcr.io": "gcloud",
"staging-k8s.gcr.io": "gcloud",
"marketplace.gcr.io": "gcloud"
},
"credsStore": "desktop"
}

Who (Which application) created this file ? . I dont know. May be previously installed docker or podman could have created this file.
If this file is created by podman, Why podman using gloud in here ? I dont know
If this file is NOT created by podman, Why podman reading from a file not created by podman ? I dont know.

Anyways Problem is resolved. But i have seen engineers raising concerns with Podman mandating for Google cloud account setup.

.docker/config.json is READ by podman for better docker compatibility I believe. It was not written by us.
