No such host // no internet connection

GitLab CI/CD
,

Hey there
I already tried a lot solving this problem.
I am creating a ci for an existing project and want to fullfill the task via docker. Therfore, I used docker build following with docker run. But I got the

dial tcp: lookup docker on X.X.X.X:53: no such host

error.
Using localhost:2375 instead of docker:2375 does not do the trick… The error message would be “docker deamon not started”.

It seems like I have no connection to the internet in my ci. The runner is installed locally on my Laptop as well as the confic.toml.

Here are my two files:

.gitlab-ci.yml


image: docker:23.0.2-alpine3.17

services:
  - name: docker:23.0.2-dind-alpine3.17
    alias: docker

  DOCKER_TLS_CERTDIR: "" # shows that no tls certs are existing

  LOCAL_IMAGE: "local-image:latest"
  DOCKER_DRIVER: overlay2

    #- docker images

    volumes = ["/var/run/docker.sock:/var/run/docker.sock"]

Unfortunally I cant use the docker registry or docker hub for this project as it is a requirement not to use it

Thanks for helping me!!
