I was using Docker Desktop on my Mac for a long time. Currently Docker desktop causing a huge issues related to starting up. Everytime it needs some tweak to run or uninstall and install it again, that takes several hours to fix every time I start working.
So I started using other Docker Desktop alternative for mac that is Colima (Container on Linux on Mac) installed with the help of the Git link.
And I am using Docker client for Docker runtime by installing it using:
brew install docker and I have logged in using docker login via terminal.
The important note here is that all the above configuration works well with Docker Desktop but after uninstalling everything related to docker and start using Colima.
While I run docker info I got the following message:
$ docker info
Client:
Context: default
Debug Mode: false
Server:
ERROR: Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?
errors pretty printing info
Here are few other information that might need:
$ colima version
colima version 0.4.2

Kustomize Version: v4.5.4
Server Version: v1.23.6+k3s1
Operating System: macOS Monterey

Any help would be highly appreciated.
After posting the question on StackOverflow I was non stop searching for a solution. Finally it took a day to fixed it (for me). While searching on google I have found a solution in this link.
Basically Colima usage $HOME/.colima/docker.sock, so first I checked if there is anything in the ~/.colima by running ls -la ~/.colima and I have found that docker.sock is there.
So I set up the DOCKER_HOST by running the following command:
$ export DOCKER_HOST="unix://$HOME/.colima/docker.sock"
and then run:
$ docker info
Now it shows everything related to Docker Server :)
Client:

Debug Mode: false
Server:

I have same problem, because i start colima before install docker, i run
$ colima delete
$ colima start
terminal print:
INFO[0000] starting colima
INFO[0000] runtime: docker
and colima docker worked!
Best is to add docker-host in .zshrc file
export DOCKER_HOST="unix://$HOME/.colima/docker.sock"
Note that in case you uninstall colima, then again install docker-desktop, then just comment above line of .zshrc file
Recently, I installed Docker for Windows and pulled the Get-starting container for WLS and it worked fine.
However, after I restarted my computer, the client doesn't start automatically, when I once start it manually nothing happened and after starting it again, it shows me docker failed to initialize
the operation has timed out.
I don't remember doing something that makes a problem.
Then I checked the version of Docker in powershell ad administrator and the result is:
PS C:\Windows\system32> docker version

Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?
I am new to *nix systems and I am trying to work on it. Please help!
Note: I have tried
sudo service docker start
* Starting Docker: docker
sudo service docker status
* Docker is not running
I have tried several ways mentioned in other threads but nothing worked. One of the ways broke the docker-ce and I had to remove it from the package and then re-install it. And it still can't fix it.
You probably can't connect because you're not the root user and you're not in the docker group. Make sure to follow the Linux post-install instructions, and don't forget to re-start your computer after adding yourself to the docker group.
You can verify whether this is the problem or not before trying all of that - does sudo docker version work?
might be a permission issue.
This are the postinstallation steps for linux:
docker post installation
you could try with sudo.
if you've the same issue with sudo, try
service docker status
and
service docker start
I've installed Docker toolbox now and I get the error for everything:

But the VM is running under VirtualBox. I have searched everywhere but can't find a solution.
UPDATE1: I'm using Windows 8.1 and also tried to start through Kinematic also.
UPDATE2: Everything worked like charm when I tried Virtualbox Test Build 5.0.3 or later. You can download here: https://www.virtualbox.org/wiki/Testbuilds
Just run:
"C:\Program Files\Docker Toolbox\docker-machine" ls
get the machine name, and then run:
"C:\Program Files\Docker Toolbox\docker-machine" env <MACHINE_NAME_HERE> --shell=[cmd|powershell]
and you should get something like this:
"C:\Program Files\Docker Toolbox\docker-machine" env default --shell=cmd
set DOCKER_TLS_VERIFY=1
set DOCKER_HOST=tcp://192.X.X.X:2376
set DOCKER_CERT_PATH=C:\Users\X\.docker\machine\machines\default
set DOCKER_MACHINE_NAME=default
# Run this command to configure your shell:
# copy and paste the above values into your command prompt
I also get an error open C:\Users\X\.docker\machine\machines\default\server.pem: The system cannot find the file specified.
and solved it by upgrading my VirtualBox to version 5.0.3 (from their nightly builds)
Long version:
I got the same problem and after and the "Using Docker from Windows Command Line Prompt (cmd.exe)" section from the installation manual put me in the right direction
Basically, the way docker works is that the "docker " commands are passed to a docker service (running on port 2375). As you are running the docker from windows host, the service actually runs on the linux host created by docker (you can see it by opening the virtualbox ui).
The usual flow is the following:
default machine is created
the starter (kinamatic / "Docker Quickstart Terminal" / cmd) of the machine waits for the machine to boot, gets it's IP address and sets the linux ip:port as the service address (instead of 127.0.0.1:2375) in few enviremnt/powershell variables
from this point all docker ... commands are send to the linux host and everything works almost as native linux
The problem is that there is some issue with the machine setup (my guess the new virtual box but I am not sure and have the time to dig into it). You can see that by runnung the ls command and notice that (at least in my case) the state of the machine is "timeout" and there is no url, unlike the output shown in the manual.
This causes the enviorment values not to be set and the docker ... commands to fail.
Apart from running the command, you can also start the Docker Quickstart Terminal that does the same thing but with sh shell
Regarding the certificate error, I tried to regenrate the certificates from within the virtual machine using:
/usr/local/bin/generate_cert --overwrite --host=default,127.0.0.1,10.0.2.15,192.168.99.100 --ca=/var/lib/boot2docker/tls/ca.pem --ca-key=/var/lib/boot2docker/tls/cakey.pem --cert=/var/lib/boot2docker/tls/server.pem --key=/var/lib/boot2docker/tls/serverkey.pem
I got "protocol error"s when tried to copy the certificate to the host machine, which reminded me an old virtualbox shared folders bug, so this may not be a problem with docker but with virtualbox - I upgraded to the latest nightly version (5.0.3-102224), regenerated the default image and that seems to solve it. As windows 10 is not officially supported yet neither by docker nor by virtualbox, I am not sure if this is the same thing that causes you to get the certificate error, In any case can try to copy the certificates from the virtual machine (you have the paths in code block) to your local user directory (it is mapped to /c/Users/X/ in the virtual machine)
The following worked for me (Docker Toolbox 1.8.1b and Windows 7). It is a simplified version of what #baptiste-gaillard outlined in the comments above. Short answer: Use VirtualBox 5.03 or later from the get-go.
Download VirtualBox 5.03 (nightly build at the time of this post) and extension pack.
Reboot laptop. (Clears out running VirtualBox stuff.)
Install VirtualBox 5.03 and extension pack 5.03.
Delete the default VM entirely (remove files).
Re-run Docker Quickstart Terminal shortcut to generate the default VM.
The Quickstart script seems to get along better with VirtualBox 5.03 with regards to creating the requisite TLS keys.
Had the same issue as you showed and Just fixed it a few hours ago.
All need to do is disable Hyper-V. Run a command prompt with administrator rights and run the following command:
bcdedit /set hypervisorlaunchtype off
Restart your PC, open virtualbox and delete default vm after relaunch, go back to docker quickstart terminal and put the following in command:
docker run hello-world
and you're done! Hope it solves your problem
this works for me
1) start the command line tool first and get the machine ip address by running
docker-machine ls command
2) Re-generate certs
docker-machine regenerate-certs
3) Set the evn variables manually in my case the location of certs was different
set DOCKER_TLS_VERIFY=1
set DOCKER_HOST=tcp://machine_IP:2376
set DOCKER_CERT_PATH=C:\Users\X.docker\machine\certs
set DOCKER_MACHINE_NAME=default
Now run docker version
Here is the output in my case

The Docker Toolbox (in 1.8.x) installation configure by default your Docker Daemon to use secure connection via the TLS protocol (version 1.8).
If you were using an older version of the daemon that wasn't secured that means at least two things :
- the port number changed from 2375 to 2376
- your daemon client need to present a certificat to communicate with you docker engine/server.
So the reply of sandiindia indicates the environment variables that precise to the docker client the good configuration to connect to the docker server/engine:
#You're using a TLS secured daemon :
set DOCKER_TLS_VERIFY=1
# Precise the Docker Host IP and port, the TLS default is 2376
set DOCKER_HOST=tcp://*<docker_host_IP>*:2376
# The paths to the certificate and client key needed to authenticate to the daemon
# You should have 3 files in this directory : ca.pem, cert.pem and key.pem
# In my case the default path looks like :
set DOCKER_CERT_PATH=C:\Users\*<username>*\.docker\machine\machines\default
#the name of your Docker Host VM :
set DOCKER_MACHINE_NAME=default

I hope it helps ;)
Close the virtual machine from Virtual Box (you don't have to delete it)
Close Kitematic
Close Docker Quickstart Terminal
Now do this in-order:
Open Kitematic
Open Docker Quickstart Terminal
Its important not to open Docker Quickstart Terminal before Kitematic, as Kitematic will initialize things for Docker Quickstart Terminal
I didn't need to execute any command line..
I hope this will help some body..
I too had the same problem, but I was able to solve it without having to type anything on the command line, it just worked out of the box.
It turns out a few initialization steps were missing, as pointed out in the accepted answer above. Why wasn't the default Docker installation already doing this? I also had missing certs. So, I uninstalled everything and restarted from scratch. However, after the installation completed, this time around do not open the Docker Quick Start terminal first, open Kitematic instead to do the first initialization for you.
Kitematic created the certs for me, set the missing env variables and then I opened the Docker Quick Start terminal. I typed docker run hello-world, then docker version and this time it worked as expected, no error messages.
Note that this didn't work when I opened the Quick Start terminal first.
I'm testing Docker inside VMWare 10 instances and I was able to duplicate this problem and its solution (workaround) in every case.
I hope this helps.
I fixed my issue by simply Removing the default VM in the VirtualBox manager, rebooting PC (just in case), and then re-running Docker Quickstart Terminal. That's it.
Docker 1.8.2 and Virtual Box 5.0.4
Update to the latest virtual box above 5.0.3
Restart the system
open virtual box and remove the default virtual machine
open the docker quick start terminal
run docker run hello-world
And you are done.
Delete and remove all old v.machines on your laptop:
1. Open VirtualBox, right click on 'default', Remove, 'Delete All files'.
2. Command Prompt (Run as Admin)> docker-machine rm default
Uninstall Virtualbox, Docker toolbox and Git.
Navigate to c:\Users\Vinita, and delete dirs. .docker and .Virtualbox
CClean files and registry.
Reboot.
Cleaning is done.
I. Download latest version of Docker tools for windows (1.10.2) from Docker Toolbox
Right click on the downloaded file and 'Run as administrator'
This will install - Docker Quickstart, Kitematic and Virtualbox.
II. Download latest test build of VirtualBox (5.01.15-105696-win.exe) from
Testbuilds – Oracle VM VirtualBox . Run as Administrator again.
(You can ignore any warnings and overwrite on the already Docker-installed VirtualBox).
So far, Nothing out of the ordinary. We just installed the software with Admin rights.
Now, Control Panel>Network and Sharing Center>Change adapter settings:
Right click VirtualBox Host-Only Network #2 for Properties.
Check> VirtualBox NDIS6 Bridged Networking Driver.
(If it is already checked, uncheck and check again.)
You are done. This is the only fix that we have employed!
Both Kitematic and Docker Quickstart should work now.
Right click on Kitematic and Run as admin the first time.
Tested on Windows 10.
I encountered exactly the same error when I run docker images after a system reboot. I used docker version 1.10 on Windows 7 64 bits with virtualbox 5.0.10 and mintty(the terminal come with Git for Windows)
Executing docker-machine ls showed me the virtual machine is in Timeout state.
$ docker-machine ls
NAME ACTIVE DRIVER STATE URL SWARM DOCKER ERRORS
default virtualbox Timeout
So I restarted the virtual machine
$ docker-machine restart default
Then list the status again told me the cert is bound to an incorrect address:
$ docker-machine ls
Unable to query docker version: Get https://192.168.56.101:2376/v1.15/version: x509: certificate is valid for 192.168.99.101, not 192.168.56.101
Then I regenerate the cert
$ docker-machine regenerate-certs default
and finally
$ eval $(docker-machine env default --shell=bash)
Then docker is working again!
With Docker 1.8.1d had the same problem, having uninstalled 1.8.1c. Eventually fixed problem by installing latest Virtual Box (5.0.18), rebooting when prompted and starting Kitematic. Kitematic fails at first and offers option to remove and re-install the VM which I did. After that my QuickStart Terminal was OK.
It sounds like the problem with virtual box,
In my case, I have performed below steps to resolve the issue
Stop Docker machine by 'docker-machine stop'
Open Network and sharing Center in Windows OS
Click on Change Adapter settings
Disable the VirtualBox-Host Only Network
Start Docker machine by 'docker-machine start'
I had the same issue with Docker Toolbox on Windows 10 Home. The steps to fix the problem from here:
run docker-machine ls to get a list, you should probably see this:
NAME ACTIVE DRIVER STATE URL SWARM DOCKER ERRORS
default - virtualbox Stopped Unknown
Optional step upgrading (be patient):
docker-machine upgrade
restart the default:
docker-machine start default
don't worry if says:
Machine "default" is already running.
now you should be able to run docker version and see something like:

This has happened a few times for me on Windows 10 with VirtualBox 5.0.14.
It seems to be related with not shutting down VirtualBox correctly (I believe) - for example, a power cut!
Shutdown the Docker VM
Close Kitematic
Start the Docker Quickstart Terminal
Type in the terminal:
docker-machine.exe -D ls
Start Kitematic. VM's show up now.
If that does not work, try 1-3 again and this time try to regenerate
certs. Then do step 4.
One thing that is odd, is that in the terminal docker images does not list them but says it cannot connect to 127.0.0.1:2375 (but docker-machine ls shows the default machine running on 192.168.99.100:2376).
Just recreate the default machine, and then run
docker-machine env default
It works for me.
if you are using docker for windows(beta) follow this steps:
Disable the "DockerNAT" network adapter
Run the "Reset to factory defaults" via the taskbar / docker / settings / Reset to factory defaults"
On my non-virtual machine, I got same error. Below steps worked for me
Right click docker->Under Settings->General do you have Expose daemon on tcp://localhost:2375 without TLS enabled? You need to if you want to access the daemon as described. But please do keep in mind that this setting is insecure as explained in the warning.
My issue was "...error getting IP address" Thanks to all the people here who have contributed their solutions which I read through and performed these steps:
Close Docker
Open VirtualBox Manager
Delete default VM
Start Kitematic first (I think this is important)

As comments suggested probably Docker daemon is not running. AFAIK, docker is not supported for RHEL 6.4. Check Docker documentation:
Red Hat Enterprise Linux 6.5 Installation
You will need 64 bit RHEL 6.5 or later, with a RHEL 6 kernel version
2.6.32-431 or higher as this has specific kernel fixes to allow Docker to work.
Docker is available for RHEL6.5 on EPEL. Please note that this package
is part of Extra Packages for Enterprise Linux (EPEL), a community
effort to create and maintain additional packages for the RHEL
distribution. Kernel support
RHEL will only support Docker via the extras channel or EPEL package
when running on kernels shipped by the distribution. There are things
like namespace changes which will cause issues if one decides to step
outside that box and run non-distro kernel packages.
Warning: Please keep your system up to date using yum update and rebooting your system. Keeping your system updated ensures critical security vulnerabilities and severe bugs (such as those found in kernel 2.6.32) are fixed.
with a fresh installation: (notice the sudo at the beginning)
$ sudo service docker start
$ sudo docker run hello-world
worked for me
