Permissions problems with docker swarm and Grafana 5.2.1

[xlson]

Copied from: grafana/grafana-docker#181

Given Docker compose file

docker-compose.yml:

version: '3.5'

services:
grafana:
image: grafana/grafana:5.2.1
volumes:
- "./grafana/:/etc/grafana/provisioning"
- "grafana_data:/var/lib/grafana"
environment:
- "GF_AUTH_ANONYMOUS_ENABLED=true"
- "GF_USERS_ALLOW_SIGN_UP=false"
ports:
- "3000:3000"
networks:
- monitoring

volumes:
grafana_data: {}

networks:
monitoring:
driver: overlay

Run above docker compose:

$ docker stack deploy --prune -c docker-compose.yml metrics

Fail to create grafana playlist to persist data:

Inspect used volume:

$ docker volume ls
DRIVER VOLUME NAME
local metrics_grafana_data

$ docker inspect metrics_grafana_data

},

}
]

List docker host rights on named volumes:

$ ls -l /var/lib/docker/volumes
drwxr-xr-x 3 root root 4096 Jul 23 17:57 metrics_grafana_data

List grafana container volume rights:

# ls -l /var/lib/grafana

Potentially related to #13187

I had the same problem.

I created in </ home / user / grafana>.

The solution was to delete and set the volume in docker-compose.yml, doing the following:
...
volumes:

• .data: / var / lib / grafana
  ...

Closing this bug report as a lot of changes have been made to the docker image since 2018 and seems no longer relevant.
