There are currently no pipelines

Hello, Here is my problem.

I made a private gitlab instance.

docker run --detach \
  --hostname 10.4.1.94 \
  --publish 9443:443 --publish 9080:80 --publish 9022:22 \
  --name gitlab-ce-15.10 \
  --restart always \
  --volume /app/gitlab-ce-15.10/config:/etc/gitlab \
  --volume /app/gitlab-ce-15.10/logs:/var/log/gitlab \
  --volume /app/gitlab-ce-15.10/data:/var/opt/gitlab \
  -e GITLAB_ROOT_PASSWORD=12345678 \
  gitlab/gitlab-ce:15.10.1-ce.0

and I want to try gitlab ci, I follow the Tutorial: Create and run your first GitLab CI/CD pipeline | GitLab

when I create .gitlab-ci.yml and fill the content as the tutorial told and commit the file to the main branch, but I can’t see any pipeline in the pipeline page.

This is what I put in the .gitlab-ci.yml

build-job:
  stage: build
  script:
    - echo "Hello, $GITLAB_USER_LOGIN!"

test-job1:
  stage: test
  script:
    - echo "This job tests something"

test-job2:
  stage: test
  script:
    - echo "This job tests something, but takes more time than test-job1."
    - echo "After the echo commands complete, it runs the sleep command for 20 seconds"
    - echo "which simulates a test that runs 20 seconds longer than test-job1"
    - sleep 20

deploy-prod:
  stage: deploy
  script:
    - echo "This job deploys something from the $CI_COMMIT_BRANCH branch."
  environment: production


I also have register a runner of my own.

I do what the same above on gitlab.com, and it behaved like the tutorial says.

SO I GUESS THIS BECAUSE the DOCKER IMAGE OR ERROR IN THE INITIAL STARTUP BY DOCKER.

help wanted.
