Tekton Kaniko build - gives push permissions errors

When running a pipeline with a Kaniko build task, I see the following error message:

E0105 13:50:28.345758      19 aws_credentials.go:77] while getting AWS credentials NoCredentialProviders: no valid providers in chain.Deprecated.  For verbose messaging see aws.Config.CredentialsChainVerboseErrorserror checking push permissions -- make sure you entered the correct tag name, and that you are authenticated correctly, and tryagain: checking push permission for"docker.io/xyz/myimage": POSThttps://index.docker.io/v2/xyz/myimage/blobs/uploads/:UNAUTHORIZED: authentication required; [map[Action:pull Class:Name:xyz/myimage Type:repository] map[Action:push Class:Name:xyz/myimage Type:repository]]

First I created a secret by generating a Docker hub access token. The secret is created using this command:

kubectl create secret docker-registry docker-credential--docker-username=xyz --docker-password=generated-docker-access-token --docker-email=xyz@mail.com --namespace=default

An alternative way is: getting the docker config info:

$ cat ~/.docker/config.json | base64 -w0 

Using this info in a secret:

apiVersion: v1kind: Secretmetadata:  name: docker-credentialdata:  .dockerconfigjson: <base-64-encoded-json-here>type: kubernetes.io/dockerconfigjson

Then I installed the Tekton Kaniko task with:

kubectl apply -fhttps://api.hub.tekton.dev/v1/resource/tekton/task/kaniko/0.6/raw

I run the pipeline in my local Docker Desktop Kubernets environment with a local Gitea repo.

Before showing the pipeline(run): I tried all kinds of solutions, like using the Docker hub password (iso token), use a Secret with the Docker credentials, etc. Nothing helps, yet.

Finally I created and ran a pipeline(run):

I also tried to use another BUILD_IMAGE:

    - name: BUILDER_IMAGE      value: bitnami/kaniko:1.19.2

This time I go this error message:
