Pipeline Created but shows no Workflow

I have written this config.yml file but under workflow it says no build, can anyone help me with that?

# Use the latest 2.1 version of CircleCI pipeline process engine.
# See: https://circleci.com/docs/2.0/configuration-reference 
version: 2.1

# Define a job to be invoked later in a workflow.
# See: https://circleci.com/docs/2.0/configuration-reference/#jobs
jobs:
  build:
    # Specify the execution environment. You can specify an image from Dockerhub or use one of our Convenience Images from CircleCI's Developer Hub.
    # See: https://circleci.com/docs/2.0/configuration-reference/#docker-machine-macos-windows-executor
    machine:
      image: ubuntu-2004:current
    resource_class: small
    # Add steps to the job
    # See: https://circleci.com/docs/2.0/configuration-reference/#steps
    steps:
      - checkout
      - run:
          name: "Docker Build"
          command:  docker build  -t optiq/main-website:${CIRCLE_BUILD_NUM} .
      - run: echo ${DOCKER_HUB_USERNAME}
      - run:
          name: "Docker Login"
          command: docker login -u ${DOCKER_HUB_USERNAME} -p ${DOCKER_HUB_PASSWORD}
      - run:
          name: "Docker Push"
          command: docker push optiq/main-website:${CIRCLE_BUILD_NUM}

# Invoke jobs via workflows
# See: https://circleci.com/docs/2.0/configuration-reference/#workflows
workflows:
  create-build:
    jobs:
      - build:
          filters:
              branches:
                only: 
                  -master
                  -development

There is not a resource_class of small for machine based linux instances - or at least not one listed

The console is very poor at reporting issues when incorrect executors are defined.
