问题
I have a gitlab runner inside a docker container, runs fine if I run an image like nginx. But now I tried to run docker in docker (dind) inside the gitlab runner and I want to run docker-compose inside the dind. Docker info runs fine, but if I try to run docker-compose I get an permission-denied error.
I linked the /usr/local/bin/docker-compose file to the gitlab runner container and enter it in the volumes parameter in the runner config.toml file.
If I try to run sudo it ends with an unknown command error, so that could not be the solution.
Do I have to link some file more or are the to many nested containers?

if you are using dind it means docker is working OK, now you just have to install docker-compose that is just simple python package and you can do it in before_script
.gitlab-ci.yml
image: docker:latest
services:
- docker:dind
variables:
DOCKER_DRIVER: overlay2
stages:
- test
before_script:
- apk add --no-cache py-pip
- pip install docker-compose
- docker info
- docker login -u gitlab-ci-token -p $CI_JOB_TOKEN docker.registry.com
test:
stage: test
script:
- cp .env.sample .env # copy environement variable
- docker-compose up -d
# run some test here

In order to have docker-compose, you need to install it for image docker, which is of version 18.09.6, build 481bc77 at the time of writing.
Since docker-compose version 1.24.0, you also need the following dependencies for docker-compose to be installed on alpine:
apk add py-pip python-dev libffi-dev openssl-dev gcc libc-dev make
Here is a sample .gitlab-ci.yml:
image: docker:stable
stages:
- deploy
services:
- docker:dind
before_script:
- apk add py-pip
- apk add python-dev libffi-dev openssl-dev gcc libc-dev make
- pip install docker-compose
deploy_app:
stage: deploy
script:
- docker-compose down
- docker-compose up -d
