How to fix docker: Got permission denied while trying to connect to the Docker daemon socket

Question

I’ve just installed docker but I have to run it with sudo every time. If I don’t add sudo I get the following error:

Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Get http://%2Fvar%2Frun%2Fdocker.sock/v1.40/containers/json: dial unix /var/run/docker.sock: connect: permission denied

Is there a way around that? I want to be able to run docker without having to type my password each time…

Hello,

According to the official Docker docs here:

https://docs.docker.com/install/linux/linux-postinstall/#manage-docker-as-a-non-root-user

You need to do the following:

To create the docker group and add your user:

Create the docker group.

sudo groupadd docker

Add your user to the docker group.

sudo usermod -aG docker ${USER}

You would need to loog out and log back in so that your group membership is re-evaluated or type the following command:

su -s ${USER}

Verify that you can run docker commands without sudo.

docker run hello-world

This command downloads a test image and runs it in a container. When the container runs, it prints an informational message and exits.
If you initially ran Docker CLI commands using sudo before adding your user to the docker group, you may see the following error, which indicates that your ~/.docker/ directory was created with incorrect permissions due to the sudo commands.

WARNING: Error loading config file: /home/user/.docker/config.json -
stat /home/user/.docker/config.json: permission denied

To fix this problem, either remove the ~/.docker/ directory (it is recreated automatically, but any custom settings are lost), or change its ownership and permissions using the following commands:

sudo chown "$USER":"$USER" /home/"$USER"/.docker -R
sudo chmod g+rwx "$HOME/.docker" -R

Here’s also a quick video demo on how to do this:

Hope that this helps! Regards, Bobby

After an upgrade I got the permission denied. Doing the steps of ‘mkb’ post install steps don’t have change anything because my user was already in the ‘docker’ group; I retry-it twice any way without success.

After an search hour this following solution finaly worked :

sudo chmod 666 /var/run/docker.sock

While doing production config i got the permission issue.I tried below solution to resolve the issue. Error Message ** ubuntu@node1:~$ docker run hello-world docker: Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Post http://%2Fvar%2Frun%2Fdocker.sock/v1.38/containers/create: dial unix /var/run/docker.sock: connect: permission denied. See 'docker run --help'. Solution:permissions of the socket indicated in the error message, /var/run/docker.sock: ubuntu@ip-172-31-21-106:/var/run$ ls -lrth docker.sock srw-rw---- 1 root root 0 Oct 17 11:08 docker.sock ubuntu@ip-172-31-21-106:/var/run$ sudo chmod 666 /var/run/docker.sock ubuntu@ip-172-31-21-106:/var/run$ ls -lrth docker.sock srw-rw-rw- 1 root root 0 Oct 17 11:08 docker.sock After changes permission for docket.sock then execute below command to check permissions. ubuntu@ip-172-31-21-106:/var/run$ docker run hello-world Unable to find image 'hello-world:latest' locally latest: Pulling from library/hello-world 1b930d010525: Pull complete Digest: sha256:c3b4ada4687bbaa170745b3e4dd8ac3f194ca95b2d0518b417fb47e5879d9b5f Status: Downloaded newer image for hello-world:latest Hello from Docker! This message shows that your installation appears to be working correctly. To generate this message, Docker took the following steps: 1. The Docker client contacted the Docker daemon. 2. The Docker daemon pulled the "hello-world" image from the Docker Hub. (amd64) 3. The Docker daemon created a new container from that image which runs the executable that produces the output you are currently reading. 4. The Docker daemon streamed that output to the Docker client, which sent it to your terminal. To try something more ambitious, you can run an Ubuntu container with: $ docker run -it ubuntu bash Share images, automate workflows, and more with a free Docker ID: https://hub.docker.com/ For more examples and ideas, visit: https://docs.docker.com/get-started/
