Trouble with install & configuring CI/CD

Hi.

We have fully configured and working perfect corporate gitlab server. And now i try to use CI/CD on it.

  1. Our sysadmin gave me a virtual server on corporate network with ubuntu 20.04 installed.
  2. I read (and understand) the docs about installing and configuring gitlab runner, docker engine, docker machine, docker hub, virtualbox software.
  3. I installed Gitlab Runner on virtual server.
  4. I register runner with “shell” type
  5. Create a project with this .gitlab-ci.yml file:
test_variable:
  before_script:
    - docker info
    - docker run --rm hello-world
  stage: test
  script:
    - echo $CI_JOB_STAGE
    - ls -la
    - tree
  1. I start the CI / CD pipeline and make sure that everything works fine.
    Then I try to run this in docker:
  2. Install the docker engine.
  3. Install the docker machine (forked version from gitlab) (I try both version)
  4. I create a new machine. Everything work perfectly.
    Now I’m testing it locally - run a docker, run new docker machine, create new machine and run it again - everything works fine.
  5. I register a new runner, with type “docker”.
  6. And this new runner does not work with the same .gitlab-ci.yml file:

Running with gitlab-runner 11.2.0 (11.2.0)
on docker-runner zQ6fuswY
Using Docker executor with image ubuntu ...
Pulling docker image gitlab-runner-helper:11.2.0 ...
ERROR: Failed to create container volume for /var/builds/work/rbushnyakov Error response from daemon: pull access denied for gitlab-runner-helper, repository does not exist or may require 'docker login': denied: requested access to the resource is denied (executor_docker.go:166:1s)
ERROR: Job failed: Error response from daemon: pull access denied for gitlab-runner-helper, repository does not exist or may require 'docker login': denied: requested access to the resource is denied (executor_docker.go:166:1s)

What am I doing wrong and what is my mistake?

My /etc/gitlab-runner/config.toml
[[runners]]
name = “simple-runner”
url = “https://git.our.corporate.site/
token = “XXXXXXXXXXXXX”
executor = “shell”
shell = “bash”
builds_dir = “/var/builds/work/”
cache_dir = “/var/builds/cache/”
[runners.cache]
[[runners]]
name = “docker-runner”
url = “https://git.our.corporate.site/
token = “XXXXXXXXXXXXXXX”
executor = “docker”
builds_dir = “/var/builds/work/”
cache_dir = “/var/builds/cache/”
[runners.docker]
tls_cert_path = “/root/.docker/machine/machines/default”
tls_verify = false
image = “ubuntu”
privileged = true
disable_cache = false
volumes = ["/var/builds/cache"]
shm_size = 0
[runners.cache]

Thank you for your attention, I really hope for help.
