illegal base64 data at input byte 8

Question

Trying to apply deployment.yaml but I got error illegal base64 data at input byte 8.

In my config.json

"auths": {
        "https://index.docker.io/v1/": {
            "auth": "16c...ad7"
        }
    }

I have put token from the docker hub

Register the secret

kubectl create secret generic regcred --from-file=.dockerconfigjson=C:\Users\Herman\.docker\config.json --type=kubernetes.io/dockerconfigjson

in my .yaml my imagePullSecrets: - name: regcred

anybody can help?

Is the content of `config.json` all surrounded by `{}` or is it as posted in the question `"auths":.....`? — gears, Dec 10 '19 at 15:46

In my case, the the oauth2accesstoken part wasn't base64 encoded as well. So once I made sure that part was also base64 encoded, along with the token in the same string, it worked.

Example Setup for oAuth and GCR

ACCESS_TOKEN=$(gcloud auth print-access-token)
export BASE_64_GCR_AUTH_TOKEN=$(echo "oauth2accesstoken:${ACCESS_TOKEN}" | base64 -w 0)
