I am trying to run a docker container inside a rails application, however I keep receiving the following error:-
container = Docker::Container.create({'Image' => 'mitc/judge'})
Excon::Errors::SocketError: No such file or directory - connect(2) for /var/run/docker.sock (Errno::ENOENT)`
The environment variables are set
bash-3.2$ env | grep DOCKER
DOCKER_HOST=tcp://192.168.99.100:2376
DOCKER_TLS_VERIFY=1
DOCKER_CERT_PATH=/Users/ayushlodha/.docker/machine/machines/dev
The container is able to run hello world
bash-3.2$ docker run mitc/judge /bin/echo 'Hello world'
Hello world
bash-3.2$ docker run -it mitc/judge
judge@4a19cdd8b328:/tmp/judge$
I am using Mac and Kitematic. What am I missing?
Since you are using Kitematic, the socket file hasn't been created yet. You nee to create it manually. You can use the command:
eval "$(docker-machine env dev)"
and then run your ruby application.
