I installed docker on windows 10 with DockerToolbox (1.11.2) executable. However, I can't evaluate my environment using docker-machine env default directly.
Instead, only when I use this command
C:\Program Files\Docker Toolbox\docker-machine.exe env default *
Can I evaluate the environment?
When I want to check help information, I also have to run
C:\Program Files\Docker Toolbox\docker.exe run --help
In their official tutorial: Install Docker for Windows, they mentioned that after installation, I could use docker,docker-machine,docker-compose directly.
In fact, I found this problem when I met this error:
C:\Program Files\Docker Toolbox\docker.exe: An error occurred trying
to connect: Post https://192.168.99.103:2376/v1.23/containers/create:
dial tcp 192.168.99.103:2376: connectex: A connection attempt failed
because the connected party did not properly respond after a period of
time, or established connection failed because connected host has
failed to respond..
And I solved it by restart my machine, and evaluate it again with the full path of the executable.
Some thing interesting is that docker-machine create -d virtualbox default worked for me while docker stop $(docker ps -a -q) failed.
I can just add those executable to environment variable on Windows.
But I want to what's happaning to that installation which caused this problem.
Screenshot of my installation console:
First, you don't have to use docker-machine env at all: you can simply ssh to your machine, and make your docker commands from there.
docker-machine ssh default
Second, try and use those commands from a regular CMD session (you don't need a bash).
As documented in docker-machine env:
$ docker-machine.exe env --shell cmd dev
set DOCKER_TLS_VERIFY=1
set DOCKER_HOST=tcp://192.168.99.101:2376
set DOCKER_CERT_PATH=C:\Users\captain\.docker\machine\machines\dev
set DOCKER_MACHINE_NAME=dev
# Run this command to configure your shell: copy and paste the above values into your command prompt
(Replace "dev" by the name of your machine, like "default" for instance)

I have freshly installed Docker for Desktop Edge in Windows 10 Home and try to build an image using the docker build command. But unfortunately, it didn't work for me, and got the below error :
CMD - docker build -t heet1996/post:0.0.1 .
error during connect: Post https://192.168.99.100:2376/v1.40/build?buildargs=%7B%7D&cachefrom=%5B%5D&cgroupparent=&cpuperiod=0&cpuquota=0&cpusetcpus=&cpusetmems=&cpushares=0&dockerfile=Dockerfile&labels=%7B%7D&memory=0&memswap=0&networkmode=default&rm=1&session=na8ugnpn6d8gnxl3z8ppx4gap&shmsize=0&t=heet1996%2Fpost%3A0.0.1&target=&ulimits=null&version=1: dial tcp 192.168.99.100:2376: connectex: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.
Earlier I was using a docker toolbox so I had to remove all the environment variables related to the Docker in my User variables before installing Docker for Desktop. After a lot of search on GitHub issues, I am still not getting the solution.
This is what I found in my service.txt file (C:\ProgramData\DockerDesktop\service.txt)
[18:27:22.232][LoggingMessageHandler][Info ] [f9b6b957] <Server end> POST http://localhost/dns/refresh-hosts -> 204 NoContent (took 118ms)
I got this error when i un-installed the docker toolbox and installed the docker desktop.
System Configuration:
OS: Windows 10 Home
Version: 21H1
Steps I Followed:
Un-installed the docker desktop.
Removed the all dockers related environment variables from the user variables.
Navigation: This System-> Properties-> Advance System Settings-> Environment Variables-> User Variables.
Re-installed the docker desktop and it's started working properly.
Try to run it on Docker CLI instead of CMD
Open Powershell as Administrator and run the below commands
cd "C:\Program Files\Docker\Docker"
./DockerCli.exe -SwitchDaemon
Docker for windows must have:
[✓] Updated Windows 10 version >=2004
[✓] WSL 2 and Default Distro (i.e ubuntu)
The steps are well documented here. These are what to do after the installation:
To confirm ubuntu's installation, open C:/Windows/System32/bash.exe aka bash.
To test if docker is properly installed, run docker version on bash. This should print the docker client and server engine.
After successfully tested and confirmed the installations, try entering your command
$ docker build -t heet1996/post:0.0.1 .
here we are talking about using Docker with PowerShell and not with WSL. And also following the addition of variables in the environment variables of Windows.
Configuration when this response was made:
Windows 10 Pro 20H2 (Build 19042.867)
Docker 20.10.5
Powershell 5.1.19041.610
I also had to configure docker in a dirty way too much, after several hours of research and a comparison of installation on a clean Windows 10 I understood where my error was.
In addition to the user environment variable also make sure that you do not have DOCKER variables in the Windows system environment variables either.
Here is where my error was, I think it was due to the installation of the Docker module
I had the DOCKER_HOST variable in my system variable environment, so i deleted it.
If you want to check all your environment variables with Powershell:
[System.Environment]::GetEnvironmentVariables()
If you really want a Docker fresh installation on Windows, you need to delete the following folders:
C:\ProgramData\Docker
C:\Program Files\Docker\Docker
$HOME\AppData\Local\Docker
$HOME\AppData\Roaming\Docker
$HOME\AppData\Roaming\Docker Desktop
$HOME\.docker
my error, therefore, produced this error:
ERROR ==> error during connect: Get http://docker.artofshell:2376/v1.24/version: dial tcp: lookup docker.artofshell: no such host
After a complete uninstall of all docker (Via chocolatey, official docker ...) and by properly installing Docker from the official executable here everything is back to normal
Then if you want to use docker via Powershell you have to change the configuration of DockerCLI as you can see on many answers
Conclusion
It is possible to use docker with Powershell you must check if the
server daemon is used by Windows/amd64, you can modify the daemon with this command cd "C:\Program Files\Docker\Docker"; .\DockerCli.exe -SwitchDeamon
You can check the configuration of the daemon with the following command: docker version
You must remove all traces of old Docker installations if you had any
You must delete the environment variables from the old installation or from the docker toolbox
You must also activate the experimental features: information here
I've set up wsl 2:
PS C:\Users\User> wsl --list --verbose
NAME STATE VERSION
* Ubuntu-18.04 Running 2
However when attempting to create a container from wsl the following error is returned:
$ lxc launch ubuntu:18.04 test
Error: Get http://unix.socket/1.0: dial unix /var/lib/lxd/unix.socket: connect: no such file or directory
How to launch an LXD container from wsl2? From my understanding it should be possible given that wsl2 is a full linux kernel.
Adding sudo before the command works.
This needs to be done for every command of lxc/lxd.
I am using Docker version 1.12.2, build bb80604 and VirtualBox 5.1.6.
I was able to install Docker Toolbox correctly but I am not able to start the default VM.
I tried to follow the instruction given here but I am still getting The system cannot find the file specified error. I don't have Hyper-V enabled on system.
F:\>docker-machine ls
NAME ACTIVE DRIVER STATE URL SWARM DOCKER ERRORS
default not found Error open C:\Users\Animesh\.docker\machine\machines\default\config.json: The system cannot find the file specified.
F:\>docker-machine env --shell=cmd
open C:\Users\Animesh\.docker\machine\machines\default\config.json: The system cannot find the file specified.
F:\>docker rm default
An error occurred trying to connect: open //./pipe/docker_engine: The system cannot find the file specified.
How can I solve this issue?
It looks like something bad happened to your docker-machine default machine.
To recover, do the following:
docker-machine rm -f default
Next, open the virtualbox GUI and make sure that there isn't a VM that corresponds with that old "default" VM, just in case. If there is, manually delete it from there.
Now, open the quickstart terminal again and it should create a new "default" virtual machine for you.
Alternatively, you can create it like this:
docker-machine create -d virtualbox --virtualbox-memory 2048 default
At that point, your sequence of commands should work as expected again.
You may need another couple of steps additional to what #programmerq mentioned.
Create empty text file: C:\Users\<user>\.docker\machine\machines\default\config.json
Stop VBoxHeadless.exe service from Windows task manager
Try docker-machine rm -f default and docker-machine create -d virtualbox --virtualbox-memory 2048 default commands afterwards to remove/add default
step 1: run: docker-machine rm -f default - (on your mac terminal or control panel)
step 2: run: docker-machine create -d virtualbox --virtualbox-memory 2048 default
It worked like miracle.
If you are a Windows Home user, you will not be able install the Docker for Windows Desktop edition, as it requires Hyper-V virtualization. This is supported only by Windows Professional and Enterprise editions.
As the Docker for Windows Desktop edition requires Hyper-V virtualization, you will not be able to install it if you are a Windows Home user. It is only supported by Windows Professional and Enterprise editions.
If you have installed Docker Toolbox and you are dealing with errors while trying to start the default machine you can create a new one by running:
docker-machine create box
the in order to see how to connect your Docker Client to the Docker Engine running on the virtual machine created run:
docker-machine env box
the command that you need to run in order to configure your shell will then appear:
eval $("C:\Program Files\Docker Toolbox\docker-machine.exe" env box)
Check that the installation is runnung correctly by running:
docker run hello-world
Then you just need to start your machine every time you need to use docker:
docker-machine start box
and follow the second and third steps above for the configuration.
I've installed Docker on my Mac about a month ago, and I now wanted to use it again. The command eval "$(docker-machine env default)" used to work perfectly before, but I now get an error:
Error checking TLS connection: default is not running. Please start it
in order to use the connection settings
I searched around for this error, but I can't really find anything about it. Does anybody know what I should do to solve this? All tips are welcome!
Your boot2docker virtual machine must be running inside Virtualbox.
List your Docker machines:
$ docker-machine ls
NAME ACTIVE DRIVER STATE URL SWARM DOCKER ERRORS
default - virtualbox Stopped Unknown
Start default machine:
$ docker-machine start default
Starting "default"...
(default) Check network to re-create if needed...
(default) Waiting for an IP...
Machine "default" was started.
Waiting for SSH to be available...
Detecting the provisioner...
Started machines may have new IP addresses. You may need to re-run the `docker-machine env` command.
To recreate your default machine:
$ docker-machine rm default
$ docker-machine create --driver virtualbox default
Then you should be able to setup your env with eval "$(docker-machine env default)".
I'm new to Docker, using Boot2Docker on OSX. After booting it, this message is given:
To connect the Docker client to the Docker daemon, please set
export DOCKER_HOST=tcp://192.168.59.103:2375
Yet even without it, basic Docker commands (eg, docker run hello-world) work fine.
The install instructions aren't very informative:
Note: If you see a message in the terminal that looks something like this:
To connect the Docker client to the Docker daemon, please set:
export DOCKER_HOST=tcp://192.168.59.103:2375
you can safely set the evironment variable as instructed.
Knowing that it's "safe" doesn't say why it's useful.
What I'm not clear on:
What is the docker "client"?
What is the docker "daemon"?
What is the docker "host"? (The Boot2Docker VM itself?)
Ok, I think I got it.
The client is the docker command installed into OS X.
The host is the Boot2Docker VM.
The daemon is a background service running inside Boot2Docker.
This variable tells the client how to connect to the daemon.
When starting Boot2Docker, the terminal window that pops up already has DOCKER_HOST set, so that's why docker commands work. However, to run Docker commands in other terminal windows, you need to set this variable in those windows.
Failing to set it gives a message like this:
$ docker run hello-world
2014/08/11 11:41:42 Post http:///var/run/docker.sock/v1.13/containers/create:
dial unix /var/run/docker.sock: no such file or directory
One way to fix that would be to simply do this:
$ export DOCKER_HOST=tcp://192.168.59.103:2375
But, as pointed out by others, it's better to do this:
$ $(boot2docker shellinit)
$ docker run hello-world
Hello from Docker. [...]
To spell out this possibly non-intuitive Bash command, running boot2docker shellinit returns a set of Bash commands that set environment variables:
export DOCKER_HOST=tcp://192.168.59.103:2376
export DOCKER_CERT_PATH=/Users/ddavison/.boot2docker/certs/boot2docker-vm
export DOCKER_TLS_VERIFY=1
Hence running $(boot2docker shellinit) generates those commands, and then runs them.
Upon investigation, it's also worth noting that when you want to start using docker in a new terminal window, the correct command is:
$(boot2docker shellinit)
I had tested these commands:
>> docker info
Get http:///var/run/docker.sock/v1.15/info: dial unix /var/run/docker.sock: no such file or directory
>> boot2docker shellinit
Writing /Users/ddavison/.boot2docker/certs/boot2docker-vm/ca.pem
Writing /Users/ddavison/.boot2docker/certs/boot2docker-vm/cert.pem

export DOCKER_CERT_PATH=/Users/ddavison/.boot2docker/certs/boot2docker-vm
export DOCKER_TLS_VERIFY=1
>> docker info
Get http:///var/run/docker.sock/v1.15/info: dial unix /var/run/docker.sock: no such file or directory
Notice that docker info returned that same error. however.. when using $(boot2docker shellinit)...

It points to the docker host! I followed these steps:
