my GitLab CI job build a example container image with Kaniko with the GitLab runner on K8s. All services are in my LAN behind a static IP. The build process pulls an ArchLinux image from my first Nexus registry service under secure domain A. Then I try do push it to the same Nexus registry into a second snapshot repo under a second domain B. Therefor I use the same Nexus user. If the job try to push, it results in the following error:
$ /kaniko/executor --context $CI_PROJECT_DIR --dockerfile $CI_PROJECT_DIR/Dockerfile --destination ${SNAPSHOT_CONTAINER_REGISTRY}/${IMAGE_NAME}
error checking push permissions -- make sure you entered the correct tag name,
and that you are authenticated correctly, and try again:
checking push permission for "B/example-app:dev-proto-kokosbot":
POST https://B/v2/example-app/blobs/uploads/:
UNAUTHORIZED: access to the requested resource is not authorized
Even if I grant the cicd user admin rights I can not push over kaniko. With the docker CLI pushing is no problem and I can reach the URL of the error in the browser and it works...
My CI config:
stages:
- build
variables:
COMMIT_SHORT_SHA: ${CI_COMMIT_SHA} at ${CI_COMMIT_BRANCH}
IMAGE_NAME: example-app:${CI_COMMIT_BRANCH}
build-job:
stage: build
image:
name: gcr.io/kaniko-project/executor:debug
entrypoint: [""]
script:
- echo [INFO] Start building container ${IMAGE_NAME}
- echo [INFO] Target container registry ${SNAPSHOT_CONTAINER_REGISTRY}
- mkdir -p /kaniko/.docker
- |
echo "{\"auths\":{
\"${CONTAINER_REGISTRY}\":{
\"auth\":\"${AUTH_REGISTRY}\"
}
},
\"${SNAPSHOT_CONTAINER_REGISTRY}\":{
\"auth\":\"${AUTH_REGISTRY}\"
}
}
}" > /kaniko/.docker/config.json
- less /kaniko/.docker/config.json

/kaniko/executor
--context $CI_PROJECT_DIR

--no-push
- >
/kaniko/executor
--context $CI_PROJECT_DIR
--dockerfile $CI_PROJECT_DIR/Dockerfile
--destination ${SNAPSHOT_CONTAINER_REGISTRY}/${IMAGE_NAME}
I have no idea where to start to understand the problem, does anyone have a clue?

I have found the problem. There is one faulty bracket in the Docker config. Unfortunately with the environment variables there are many brackets. Therefore this is not easy noticeable.
The more astonishing it is that Kaniko, with a verbosity of tracing, does not spit out an error...
