Kaniko: Unrecognized challenge: BASIC

[ErikWegner]

I am trying to build a container image inside kubernetes. The command docker run -v ~/.docker:/root/.docker -v ~/workspace:/workspace gcr.io/kaniko-project/executor:latest -f Dockerfile -d privateregistry.example.com/org1/hello:v1 -c /workspace builds the image and tries to upload it to my private registry. The output is:

time="2018-06-01T11:40:00Z" level=info msg="Unpacking filesystem of hello-world:linux..."

Credentials for the private registry are inside the .docker/config.json file:

{
  "auths": {
    "privateregistry.example.com": {
      "auth": "base64 encoded username:password"
    }
  }
}

What does the error message mean? Which steps may help?

Initially I thought the error might be coming from here while trying to get the config file, but I was able to build an image based off hello-world:linux and push it to GCR and Docker registry.

Could you provide the Dockerfile you're trying to build?

EDIT: your docker config may be using a different auth path, which could explain the error

[ErikWegner]

This is my Dockerfile:

FROM hello-world:linux

How do I know which auth path is required?

This is fixed upstream 👍

Works now, thank you.
