How to connect gitlab-runner using docker container?

Question

GitLab

Hello!
Community help needed!
1. I started gitlab according to the instructions:
https://ealebed.github.io/posts/2017/gitlab-gitlab...
2. I try to register a runner for the created project according to the instructions:
https://ealebed.github.io/posts/ 2017/gitlab-ci-h...
3. problem: when run according to the instructions, the following error is issued:
Runtime platform arch=amd64 os=linux pid=77 revision=c127439c version=13.0.0
Running in system-mode.
PANIC: The registration-token needs to be entered
As I understand it, there is a problem with network accessibility from a container to another container (the token is entered correctly, taken from the project settings) Although the author of the instructions about network settings does not specify anything, and as I understand it, everything should be out of the box according to his instructions.
I ask for help, maybe someone recently ran gitlab in containers with full "strapping" for CD / CI.
Thank you!

SOLVED
used the old version of giblab, but tried to connect from the new runner.
During this time, I realized one thing, always use the official documentation of the product that you want to master!!!
The attentive Alex D from the telegram DevOps channel helped in the decision.
