I have a gitlab container running inside CentOS 8 and likewise the runner (they are not in the same stack, but the runner was registered correctly). I tried to run a basic job to check the integration of the runner with Gitlab and every time I tried to run what was inside gitlab-ci.yml it appeared that the job was pending, as shown in the image below:
So I thought that something that was inside the .yml file could be wrong, so I used one from Gitlab’s own documentation and it remains the same. Thank you in advance, who can help me 
Ps .: Below are some more images of the situation for more details of what the problem may be. I put the runner as restricted to a project to see if it would work, but it still continued anyway
