On running docker images, I am getting error
error during connect: Get http://%2F%2F.%2Fpipe%2Fdocker_engine/v1.40/images/json:
open //./pipe/docker_engine: The system cannot find the file specified.
In the default daemon configuration on Windows, the docker client must be
run elevated to connect. This error may also indicate that the docker
daemon is not running.
I am on Windows 10 Home and have tried to install/reinstall Docker but I keep getting the error. Things were working fine an hour back!
Can you check if you have a VM running under docker-machine? You can run the below command:
docker-machine ls
And if you haven't installed docker-machine, please install it.
Ref:- https://docs.docker.com/toolbox/toolbox_install_windows/
Note:- Make sure enabled the BIOS virtualization.

I am a Windows user trying to run "docker-compose up" command but continue to get the error in title. I am writing this code in Ubuntu using WSL 2.
I have tried everything - from this post to this post - and have made sure I have docker installed correctly. When I run "sudo service docker start" I get "docker: unrecognized service". I'm thinking of switching to Podman (though would prefer not to if can avoid it) to get past having to use the docker daemon- though I can't seem to get this to run in wsl.
Any and all guidance would be appreciated!
This typically means that your Docker Service is not running.
Open RUN and type services.msc, then click OK or hit enter
Search for service named as Docker Desktop Service.
Make sure it is running.
You can also set the Docker service to start when you login from Docker Desktop GUI setting panel
Running Ubuntu desktop as server as a VM on ESXI and have Docker running there and Home assistant.
The problem is - When power source breaks, the machine autorestarts, VM reboots, but docker does not always boot up and Home assistant doesn't work either.
When I type in
sudo docker ps
Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running
Then I got to ESXI - hit restart and all works like a charm.
What can it be guys?
You need to enable the docker service to run it automatically when the system restarts. The command is:
sudo systemctl enable docker
thank you, i tried that and got this line
Created symlink /etc/systemd/system/multi-user.target.wants/docker.service → /lib/systemd/system/docker.service.
i guess this should help me out.
but i still don't understand why it autostarted sometimes, and sometimes not
I'm running Ubuntu 20.4. and installed Docker by following the steps from the docs https://docs.docker.com/engine/install/ubuntu/#install-using-the-repository .
I installed Rider from Jetbrains Toolbox and want to setup Docker for my project. The Docker plugin is installed by default. I made sure that Docker is running via systemctl status docker.
I followed this guide on how to setup Docker for Rider https://blog.jetbrains.com/dotnet/2018/07/18/debugging-asp-net-core-apps-local-docker-container/ but unfortunately I get this error
Cannot connect:
io.netty.channel.AbstractChannel$AnnotatedConnectException: Connection
refused: localhost/127.0.0.1:2375 caused by:
java.net.ConnectException: Connection refused
What is missing or wrong?
In that dialog, check "Unix socket".
This will contact the Docker daemon via the special file /var/run/docker.sock. You may need to adjust your user's permissions (typically by making yourself a member of the docker group) to get access to that file.
The "TCP socket" option is for an unusual and hard-to-securely-configure mode of connecting to Docker. (Anyone who can run any docker command can run a container as root, and bind-mount any file from the host; you really don't want to make this level of access network-accessible.) You shouldn't ever need the TCP socket mode..
What are the dependencies and steps to connect to a remote docker container from VSCode? So I can properly compile and run the code with the tools in my container environment?
I have tried to follow the instructions here without much luck:
https://code.visualstudio.com/docs/remote/containers-advanced#_developing-inside-a-container-on-a-remote-docker-host
My setup involves:
Host with VSCode, no docker installed, ssh client installed, ssh keys are in place
Server with VSCode, docker installed, ssh client and server installed
Docker container already running on Server
Host can connect to Server, through VSCode using the Remote Development Version: 0.17.0 extension, through Remote - SSH Version: 0.47.2 extension
Version: 0.47.2
Server can connect to Docker container, through VSCode using the Remote Development Version: 0.17.0 extension, through Remote - Containers Version: 0.83.1 extension.
How do I connect Host to a Running Docker container?
UPDATE 1
Small advance
I have added this line to my ~/.config/Code/User/settings.json file. The option gets highlighed with a message unknown configuration setting
{
...
"docker.host":"tcp://localhost:23750",
...
}
Run this command in another terminal:
ssh -N -L localhost:23750:/var/run/docker.sock <user>#<serveraddr>
And now I can see the running containers in Remote explorer > Containers > Other Containers. However, when trying to connect to it, I get the following error message.
Setting up container with bc1700db049858ba20f1c830bbeff6d6a4e04de58a2b35a61df1016788bc07db
Docker returned an error code 127, signal null, message: Command failed: docker system info
/bin/sh: docker: command not found
So, it appears that docker must be installed on the host machine to prevent the last mentioned error.
Note: docker service does not need to be running in the host (systemctl disable docker)
With this in mind, these are the steps.
Host:
Install docker and ssh client
Add your user to docker group
Install VSCode
Configure Server
(After server config below): edit ~/.config/Code/User/settings.json with
"docker.host":"tcp://localhost:23750",
Configure your ssh keys for the Server
(After every reboot run on terminal: ssh -N -L localhost:23750:/var/run/docker.sock <user>#<serveraddr>)
Run VSCode and install Remote Development extension. Restart VSCode
Now you should see your running containers in VSCode Remote explorer > Containers > Other Containers
Server:
Install docker and ssh server
Install VSCode (this may not be a requirement on the server)
Add your user to docker group and start your container
I realize this was already answered, but I stumbled across this while trying to set this up myself today. I found an additional issue I had appeared to be that my local SSH key had not been added to the agent. I was following the instructions here.
I am running Windows 10 Version 1909 Build 18363.1082.
After doing an ssh-add $Env:USERPROFILE\.ssh\id_rsa and restarting the ssh-agent, I was able to connect to the remote container without having to employ the ssh tunneling method you show above.
I'm trying to run this command :
docker daemon --insecure-registry 192.168.99.100:5000
but i'm gettin ghe following error:
exec: "dockerd": executable file not found in %PATH%
I'm using win7 and docker-toolbox 1.12.2 with VM Virtual Box.
What is the problem here?
there is a way to run this command?
That is indeed what issue 27102 report:
Docker Daemon command dockerd not found on latest stable Docker for Mac and Docker Toolbox
(this is for mac but also applies on Windows)
Docker for Mac should probably print a different message, also, we may need to check if the CLI is on the same "host" as the daemon, and print a different message based on that (as running dockerd wont work if the daemon is on a remote server).
the daemon runs in a Linux virtual machine, so you do not need to (and cannot) run it manually. It is already running of the whale is in the top bar.
Conclusion: (Aug. 2021):
I'm closing this ticket, because the current behaviour is as expected.
I think this was originally opened when the docker cli still had a daemon subcommand (during the transition from a single binary to separate binaries for the cli and daemon), which is no longer the case.
The dockerd binary, which is the docker daemon, is not available for macOS (and unlikely will be), because it's a Linux binary that (on Docker Desktop for Mac) runs inside the Docker Desktop VM.
In 2022:
I'm having this exact same issue on the most recent MacOs version (Monterey, Version 12.3.1 (21E258)).
I've uninstalled Docker & reinstalled several times, if I run docker ps or docker run hello-world as paulinechi describes, I get that same error:
docker: Cannot connect to the Docker daemon at `tcp://35.215.110.128:2375`.
Is the docker daemon running?...
Answer:
Make sure you don't have a DOCKER_HOST environment variable set; from that error, it looks like either you have a DOCKER_HOST env-var, or possibly a docker context that defines a non-standard location to connect to the daemon.
The default should be to connect with the Engine API using a unix-socket (unix:///var/run/docker.sock)
Confirmation:
I forgot I was pointing to a DOCKER_HOST on a remote machine that has since shut down.
