Kaniko (GitLab CI, K8s) не может выполнить push в Nexus Repository Manager: UNAUTHORIZED: access to the requested resource is not authorized

мое задание GitLab CI собирает образ примера контейнера с Kaniko с помощью GitLab runner на K8s. Все службы находятся в моей локальной сети за статическим IP. Процесс сборки извлекает образ ArchLinux из моей первой службы реестра Nexus в защищенном домене A. Затем я пытаюсь вытолкнуть его в тот же реестр Nexus во второй репозиторий snapshot под вторым доменом B. Поэтому я использую того же пользователя Nexus. При попытке выполнить push возникает следующая ошибка:

$ /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

Даже если я предоставлю пользователю cicd права администратора, я не могу выполнить push через kaniko. С помощью docker CLI проталкивание происходит без проблем, и я могу перейти на URL ошибки в браузере, и он работает...

Мой конфиг CI:

stages:
  - build

variables:
  COMMIT_SHORT_SHA: ${CI_COMMIT_SHA} at ${CI_COMMIT_BRANCH}
  IMAGE_NAME: example-app:${CI_COMMIT_BRANCH}
  
build-job:

  image:
    name: gcr.io/kaniko-project/executor:debug
    entrypoint: [""]

    - 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 
      --dockerfile $CI_PROJECT_DIR/Dockerfile 
      --destination ${SNAPSHOT_CONTAINER_REGISTRY}/${IMAGE_NAME}
      --no-push
    - >
      /kaniko/executor 
      --context $CI_PROJECT_DIR 
      --dockerfile $CI_PROJECT_DIR/Dockerfile 
      --destination ${SNAPSHOT_CONTAINER_REGISTRY}/${IMAGE_NAME} 

Я понятия не имею, с чего начать, чтобы понять проблему, есть ли у кого-нибудь подсказка?

Приветствую, Kokos Bot.
