I am able to run docker without sudo but after sometimes it again asks for permissions and I am not able to Attach container in VS code
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
To sort out permission errors and to run containers, check the following command
sudo chmod 666 /var/run/docker.sock

I am trying to use watchtower container (https://containrrr.dev/watchtower/) in RHEL 8.0 using podman.
Since docker is not officially supported by RHEL 8.0, I have not installed docker-engine in this VM.
I have started podman.socket service and podman.sock is located on /run/podman/podman.sock
When I give podman-compose up -d command all the other containers start successfully without any error but watchtower container Exits with code (1).
This is the logs generated by watchtower container:
time="2022-01-20T13:45:50Z" level=error msg="Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Get \"http://%2Fvar%2Frun%2Fdocker.sock/v1.25/containers/json?filters=%7B%22status%22%3A%7B%22running%22%3Atrue%7D%7D&limit=0\": dial unix /var/run/docker.sock: connect: permission denied"
0
I gave executing permission to /run/podman/podman.sock file but still getting this error.
Snippet of docker-compose.yml with watchtower service.
watchtower:
image: index.docker.io/containrrr/watchtower:1.3.0
volumes:
- /run/podman/podman.sock:/var/run/docker.sock
Since I do not have docker.sock, I am mounting podman.sock to docker.sock so that watchtower can communicate with docker API.
How can I fix it? (I don't want to install docker)
The default podman socket is root:root 660. You may have to create a group, and/or chmod the socket.
I'm running Jenkins helm on GKE standard cluster with Container-Optimized OS with Docker (cos) image.
I'm running jenkins agent with docker installed and jenkins user added to docker group. I'm mounting /var/run/docker.sock as volume .. also tried t run with UID 1000.
-v /var/run/docker.sock:/var/run/docker.sock
But still getting dial unix /var/run/docker.sock: connect: permission denied ?! Any idea what I'm missing here ?
In addition to #again comment, below are possible reasons to look for regarding pemission denied error:
Docker is not installed on host
UID 1000 does not have permission to /var/run/docker.sock (try to chmod 777 the file temporarily and reduce permssion as needed)
Check Host and Container docker ID, must have the same UID
Also, you can refer on related links below for possible answers.
Docker: Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock
Run Docker as jenkins-agent, in a docker-container, as non-root user
Use docker inside docker with jenkins user #263
docker.sock permission denied
I’ve just run Dockerfile in jenkins setup then I get the following error:

docker.deamon tell us this:
The Docker daemon binds to a Unix socket instead of a TCP port. By
default that Unix socket is owned by the user root and other users can
only access it using sudo. The Docker daemon always runs as the root
user.
If you don’t want to preface the docker command with sudo, create a
Unix group called docker and add users to it. When the Docker daemon
starts, it creates a Unix socket accessible by members of the docker
group.
Check if the docker group already exists:
cat /etc/group | grep docker
if it doesn't, create with this command:
sudo groupadd docker
add the jenkins user to docker group:
sudo usermod -a -G docker jenkins-user
newgrp docker
Check if is it worked...
$ cat /etc/group | grep docker
docker:x:***:jenkins-user
Restart the jenkins
logout, and login again
Or you can just try run the docker with sudo.
I mounted /var/run/docker.sock under the non-root user, and checked that the permission role was nobody. Why not the default root
The mount code is as follows
docker run -it --rm --entrypoint='' -v /var/run/docker.sock:/var/run/docker.sock controller:v1 bash
bash-5.0# ls /var/run/ -lh
total 0
srw-rw---- 1 nobody nobody 0 Feb 3 07:48 docker.sock
At this time, docker daemon cannot be connected by running docker command
bash-5.0# docker ps
Got permission denied while trying to connect to the Docker daemon socket at
unix:///var/run/docker.sock: Get http://%2Fvar%2Frun%2Fdocker.sock/v1.39/containers/json:
dial unix /var/run/docker.sock: connect: permission denied
I have granted the non-root user Docker permission with sudo usermod-ag Docker your-user
I hope to use Docker CLI in docker container to perform some operations, such as Docker Run, Docker Ps, Docker images and so on
I would appreciate it if you could tell me how to solve it?
Issue for
http:///var/run/docker.sock/v1.19/containers/json: dial unix /var/run/docker.sock: permission denied. Are you trying to connect to a TLS-enabled daemon without TLS?
I got the solution for this
Add the login user for ssh let's say gse to the docker group
sudo usermod -aG docker "gse"
then restart the vm using sudo reboot
and do docker ps and it works :-)
Try to use with root user or add your user in docker group.
