Issue: Cannot connect to the Docker daemon at unix:///var/run/docker.sock.

[Angelo B. J. Luidens]

Hi,

I am getting the following message in my browser after I login to Swirl: "Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?"

Could provide my with advise or direction what I am missing or doing wrong?

Below is my docker-compose file section for starting Swirl and MongoDB:

` swirl:
image: cuigh/swirl
container_name: swirl
depends_on:
- mongo
ports:
- 8001:8001
environment:
# - DB_TYPE=bolt
- PGID=998
- DB_ADDRESS=/data/swirl
- DB_ADDRESS=mongo:27017/swirl # - DB_ADDRESS=/data/swirl
# - RESCRAMBLE=true
security_opt:
- apparmor:unconfined
- seccomp:unconfined
volumes:
- /var/run/docker.sock,dst=/var/run/docker.sock
- /var/lib/docker/:/var/lib/docker:ro
- /path/swirl/data=/data/swirl
networks:
- web
- net
deploy:
# privileged: true
mode: replicated
replicas: 1
update_config:
order: start-first # get new container running first before removing old, for less downtime
rollback_config:
order: start-first # get new container running first before removing old, for less downtime
placement:
constraints:
- node.role==manager

mongo:
image: mongo
volumes:
- /path/mongo/data:/data/db
networks:
- net
deploy:
mode: replicated
replicas: 1
update_config:
order: start-first # get new container running first before removing old, for less downtime
rollback_config:
order: start-first # get new container running first before removing old, for less downtime

placement:

constraints: [node.hostname == mongo]`

Thank you in advance.

Angelo

1. Check if docker service is running
2. That error is likely a result of running docker in docker, refer to this article

It looks like your Docker didn't run. check the sock file:/var/run/docker.sock
