The issue I am having is: Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?.
I have had this issue before and was fixed by removing the docker group, adding again and adding myself to the group. Tried that this time, no luck.
For some reason WSL does not like it when you do a system restart and seems to stop docker from working properly. However, docker is not being helpful with their debugging...
I want to be able to restart and it work fine without having to spend hours finding a new solution that might work.
I have tried lots of solutions from adding user to group and signing out and in to tinkering with the docker socket itself, nothing is working and it is really frustrating. I think it has something to do with user groups since that was the issue last time and always has been, but the previous workaround didn't work...
I have a makefile which I used to run docker commands as it is more effecient, but even when I run docker ps I get this:
Cannot connect to the Docker daemon at unix:///var/run/docker.sock.
Is the docker daemon running?
The result I want is for docker to tell me that the it is starting my containers, yet it's not.
probably you should do restart the docker service by following command
sudo service docker restart
if even though it is not resolved then refer this link-->
https://docs.docker.com/install/linux/linux-postinstall/#configure-where-the-docker-daemon-listens-for-connections
I guess you already enabled docker service via sudo systemctl enable docker which will restart docker service on host restart.
Hope below references will help you fixing your issue as they look similar to yours.
Cannot connect to the Docker daemon at unix:/var/run/docker.sock. Is the docker daemon running?
https://forums.docker.com/t/cant-run-docker-in-ubuntu-14-04-cannot-connect-to-the-docker-daemon-at-unix-var-run-docker-sock/31355
Solution that worked for me was to:
1)sudo groupadd docker (delete and re-add the group if it's already made)
2)sudo usermod -aG docker $(whoami)
3)sudo newgrp docker (as you cannot log-in/out again on WSL)
fixed!

I am trying to configure my python interpreter to use docker but keep getting errors that it cannot connect to the docker daemon, even though I have docker desktop up and running.
Connecting to Docker daemon…
Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?
I have tried solutions from:
Docker is Running But Pycharm Cannot Connect to Docker Daemon
and
Pycharm 2022 cannot connect to the docker service. It does not find it
I do not have to use sudo to run docker commands, and I tried disabling the use.targets.api and still got the same error.
If anyone has any advice, it would be greatly appreciated.
I had the same problem with pyCharm 2022.3 and Docker for Mac. Restarting Docker for Mac does not help, but after reboot of Macbook i got alert with password authorization request from Docker (about symlinking). Since authorization, everything is working properly.
i am relatively new to docker.
Sadly i cannot restart containers, without having to restart the whole docker daemon, because i get the aforementioned error. The port is not in use and I cannot find the container running anymore with "docker ps -a".
The only way i can restart containers is by killing the whole docker daemon and the starting it.
I would be very grateful for any help!
I tried to search for used ports, but the needed ports were not in use. Then i tried reinstalling docker-compose, which did not help either.
Edit: I am using Ubuntu 20.04.5 LTS.
I tried restarting containers with docker restart /container/.
I checked the used ports with: sudo lsof -i tcp:80.
And I don't get the bind error, which docker gives for ports, but the one, where it thinks a container is running, but really isn't.
Thanks in advance!
I'm using docker in wsl2. I followed this guide for the setup and everything covered therein seems to work.
Now when I try to build a docker image in wsl2 with docker build . I get the error Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?
I assume that I have to tell docker build on which IP the docker host is running (similar to docker -H 172.20.5.64 run --rm hello-world), but I have no idea how to do this?
I had the same problem, here is the solution, that worked for me:
I had to stop docker
sudo docker service stop
I had to start docker daemon
sudo dockerd
I had to stop docker daemon by pressing ctrl + z
Than i had to move the process in the background
bg %1
Then I was able to restart docker
sudo docker service start
After that, I did no longer get an error.
I hope this works for you too.
I want to install a package by docker, following instruction in: https://dynamic-fba.readthedocs.io/en/latest/installation.html#installing-from-source
I installed ubuntu and then Docker. But I don't understand what I need to do next. There it is said to type (docker run -it -v ${PWD}:/opt/examples davidtourigny/dfba python3 examples/example1.py). I excatly type it in ubuntu but I get this error:
docker: Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?.
See 'docker run --help'.
Using alternative method of dockerfile, I also get error. I don't know how to make use of make build, but used build instead following tutorials on the web.
It's my first time using Docker and I don't know what to do.
Any help is very appreciated.
The Docker application has two components, a back-end server, and a front-end cli. This way you can do cool stuff like control Docker remotely or have orchestration frameworks that manage multiple Docker nodes over the network like Kubernates.
For security, the Docker back-end server is not exposed on a normal TCP port but it uses a unix domain socket (Linux magic that makes a file act as a port) at unix:///var/run/docker.sock.
When you execute docker run -it ... the cli application will attempt to connect to the backend server, but it looks like the daemon/server is probably not running.
Try to check that daemon is running. If you are using systemd you can check with
systemctl status docker and start if is stopped with systemctl start docker finally it might be good to enable it to make sure it starts automatically on reboot, you can do that with systemctl enable docker
Make sure to start docker service (you can either go for systemctl start docker or reboot your computer).
Once this is done, it is likely that your user has no permissions to communicate with Docker without sudo. Docker has privileged access to your hardware and therefore giving a user the docker group is required for security reasons.
Run:
sudo usermod -aG docker $USER
groupadd docker
docker run hello-world
This will add you to docker group, reflect the changes inmediately and run a sample image from Docker.
If all was okay, the last command should tell you "Hello from Docker".
Is there any way to stop a docker container which started with --restart=always like following
sudo docker run -it --restart=always <image_id>
Here's the mighty eagle that docker has recently included. :D
You can update docker container.
use sudo docker update --restart=no <container_id> to update --restart flag of the container.
Now you can stop the container.
You should be able to just use docker stop and then docker rm to make sure the container doesn't restart when the daemon restarts.
Your question is an issue on the docker github and someone has made some comments about to how to solve here
I'm not sure if it's intended behavior to restart a stopped container on daemon restart... but for sure docker rm would be all that is needed, no need to remove the image.
If you use docker stop or docker kill, you're manually stopping the container so it will not restart. You can do some tests about restart policies: restarting the docker daemon, rebooting your server, using a CMD inside a container and running an exit...

TL;DR
Also check docker swarm if there are any stacks that spin up containers there. Simply run docker stack ls followed by docker rm <stack_name>.
Longer version
This is not exactly an answer to your question, but I had a very similar issue where containers kept spinning up even if I ran docker update --restart=no <container_id>, docker stop <container_id> and docker rm <container_id>. These were some old containers, so I had no clue how I generated them.
After some Googling, I realized that it was a docker swarm stack that kept spinning up containers. By running docker stack ls followed by docker rm <stack_name>, I was able to stop the auto spin-up of the containers and thus remove them entirely.
