Recently i tried to install Gitlab on Ubuntu machine using docker and docker-compose. This was only done for testing so i can later install it on other machine.
However, i have a problem with removing/deleting gitlab containers.
I tried docker-compose down and killing all processes related to gitlab containers but they keep restarting even if i somehow manage to delete images.
This is my docker-compose.yml file
version: "3.6"
services:
gitlab:
image: gitlab/gitlab-ee:latest
ports:
- "2222:22"
- "8080:80"
- "8081:443"
volumes:
- $GITLAB_HOME/data:/var/opt/gitlab
- $GITLAB_HOME/logs:/var/log/gitlab
- $GITLAB_HOME/config:/etc/gitlab
shm_size: '256m'
environment:
GITLAB_OMNIBUS_CONFIG: "from_file('/omnibus_config.rb')"
configs:
- source: gitlab
target: /omnibus_config.rb
secrets:
- gitlab_root_password
gitlab-runner:
image: gitlab/gitlab-runner:alpine
deploy:
mode: replicated
replicas: 4
configs:
gitlab:
file: ./gitlab.rb
secrets:
gitlab_root_password:
file: ./root_password.txt
Some of the commands i tried to kill processes:
kill -9 $(ps aux | grep gitlab | awk '{print $2}')
docker rm -f $(docker ps -aqf name="gitlab") && docker rmi --force $(docker images | grep gitlab | awk '{print $3}')
I also tried to update containers with no restart policy:
docker update --restart=no container-id
But nothing of this seems to work.
This is docker ps response:

Any ideas of what i should be looking for?
I found the solution. Problem was that i didn't use
docker-compose up -d
to start my containers. Instead i used
docker stack deploy --compose-file docker-compose.yml mystack
as it is written in documentation.
Since i didn't know much about docker stack, i did a quick internet search. This is the article that i found: https://vsupalov.com/difference-docker-compose-and-docker-stack/
The Difference Docker stack is ignoring “build” instructions. You can’t build new images using the stack commands. It need pre-built images to exist. So docker-compose is better suited for development scenarios.
There are also parts of the compose-file specification which are ignored by docker-compose or the stack commands.
As i understand, the problem is that stack only uses pre-built images and ignores some of the docker-compose commands such as restart policy. That's why
docker update --restart=no container-id
didn't work.
I still don't understand why killing all the processes and removing containers/images didn't work. I guess there must be some parent process that i didn't found.
