Can't push using service account key and docker-credentials-gcr

[tejal29]

Hey folks,

I am trying to debug an issue in Kaniko GoogleContainerTools/kaniko#1786

I am trying the following steps

/workspace # /busybox/cat /kaniko/.docker/config.json 
{
	"auths": {},
	"credHelpers": {
		"gcr.io": "gcr"
	}
}
/workspace #  export GOOGLE_APPLICATION_CREDENTAILS=service_account.json

cat /kaniko/.config/gcloud/docker_credential_gcr_config.json 
{"TokenSources":["env"]}
/workspace # echo "gcr.io" | docker-credential-gcr get


docker-credential-gcr/helper: could not retrieve GCR's access token: oauth2: cannot fetch token: Post "https://oauth2.googleapis.com/token": dial tcp: lookup oauth2.googleapis.com: device or resource busy

I was able to get echo "gcr.io" | docker-credential-gcr get working before. Is there something missing in my flow?

This doesn't look like a problem here 🤔

This seems like it might be related to GoogleContainerTools/kaniko#1631

I've never seen the device or resource busy error before, using ggcr or kaniko or anything else. Off the top of my head I don't think it's related to ggcr, but I'm willing to be convinced.

hmm, I was able to use the above instructions before. Wondering what changed.
