Couldn't Connect To Docker Daemon. You Might Need To Start Docker For Mac.

Couldn't Connect To Docker Daemon. You Might Need To Start Docker For Mac. 9,3/10 6879 votes

I have setup Docker environment on MAC platform. Note that Compose is v1.22, embedded with Docker image (not as separate installation) as part of latest release. Although your instructions suggest v1.6 pre-req. To enable the daemon to start at boot time or not use sudo systemctl enable docker and sudo systemctl disable docker respectively. Overriding Defaults for the Docker Daemon By default the systemd configuration files controlling the service are under the folder /usr/lib/systemd/system.

I am trying to go through the example here. When I deploy it locally and issue the command graphcool local up I receive this error. Couldn't connect to Docker daemon - you might need to run docker-machine start default. Any help would be appreciated.

I am on a mac with the latest macOS High Sierra installed. Docker and docker-compose are both installed also. I also ran docker-machine start default and received this error.

I've installed Docker through the Software store, which indicated that it was a Snap package. Which is fine by me, I guess, but unfortunately, every Docker command I've tried doesn't work: $ docker info Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Get dial unix /var/run/docker.sock: connect: permission denied Any idea how to fix this? Edit: I've worked around this for now by installing Docker from, which might work for people browsing this question in the future as well.

I'm leaving the question open for those who want to be able to run it from the Snap, though. This is from the GitHub page, did you try these exact steps: If you are using Ubuntu Core 16, Connect the docker:home plug as it's not auto-connected by default: $ sudo snap connect docker:home If you are using an alternative snap-compatible Linux distribution ('classic' in snap lingo), and would like to run docker as a normal user: Create and join the docker group. $ sudo addgroup --system docker $ sudo adduser $USER docker $ newgrp docker You will also need to disable and re-enable the docker snap if you added the group while it was running. $ sudo snap disable docker $ sudo snap enable docker From. I assume, your username is already in docker group.

To check this, issue below command. Id -nG If not you need to add your user into the docker group by below command. Sudo groupadd docker sudo usermod -aG docker $USER When you execute the command, sudo systemctl start docker, it creates a docker process. That docker process contains dockerd daemon thread. The command also creates default docker.sock Unix socket.

The docker.sock socket is continuously listened by dockerd daemon thread. This makes you can do kernel-level IPC with docker.pid process. To be able to use this docker socket, you need to have proper permission from the process level ( docker.pid) and file level ( docker.sock). So, executing below two commands should solve your issue. Sudo chmod a+rwx /var/run/docker.sock # You can provide just execute permission sudo chmod a+rwx /var/run/docker.pid.

You need to start the daemon with a separate command: I got this from: After the installation finishes, Docker usually starts up on its own, but for the next part to work you will need to stop it. Sudo service docker stop Then run the daemon with the following command: sudo nohup docker daemon -H tcp://0.0.0.0:2375 -H unix:///var/run/docker.sock & The script leaves the daemon running in the background, and with the Docker ready you can test that it is accepting commands.
