Git push executes unwanter Gitlab runner

Question

I'm new to GitLab CI. Constructed very simple YAML just for test purposes. I configured runner with shell executor on my AWS machine and register it properly. In Settings/Pipelines I see activated runner. When I push something on my repository following YAML should be executed: docker-auto-scale

before_script:
  - npm install

cache:
  paths:
    - node_modules/

publish:
  stage: deploy
  script:
    - node app.js

Instead completly another runner is continouosly started (whatever I change - even when I turn off runner on my machine). It is runner with ID: Runner: #40786. In logs I can read:

Running with gitlab-ci-multi-runner 9.5.0 (413da38) on docker-auto-scale (e11ae361) Using Docker executor with image ruby:2.1 ...

I didn't even have Docker executor - I chose shell one. What is going on? Please support.

Answer 1

When you registered the new runner, did you give it a tag?

if so, and it would be e.g. my_tag modify your yaml file and append:

publish:
  stage: deploy
  script:
  - node app.js
  tags:
  - my_tag

otherwise the build will be picked up by a shared runner.
