I tried running remote commands with sshd open locally on Mac.
For example
$ ssh username#localhost ls
Command like this work just fine.
But
$ ssh username#localhost docker
is not executed and the following error is displayed.
$ ssh username#localhost docker
sh: docker: command not found
If I connect with the command and run the docker command, it runs normally.
$ssh username#localhost
$docker
Usage: docker [OPTIONS] COMMAND
A self-sufficient runtime for containers
Options:
--config string Location of client config files (default "/Users/7143213/.docker")
-c, --context string Name of the context to use to connect to the daemon (overrides DOCKER_HOST env var and default context set
with "docker context use")
-D, --debug Enable debug mode
-H, --host list Daemon socket(s) to connect to
-l, --log-level string Set the logging level ("debug"|"info"|"warn"|"error"|"fatal") (default "info")
--tls Use TLS; implied by --tlsverify
--tlscacert string Trust certs signed only by this CA (default "/Users/7143213/.docker/ca.pem")
--tlscert string Path to TLS certificate file (default "/Users/7143213/.docker/cert.pem")
--tlskey string Path to TLS key file (default "/Users/7143213/.docker/key.pem")
--tlsverify Use TLS and verify the remote
-v, --version Print version information and quit
...
ssh username#localhost /usr/local/bin/docker
Even if I write down the full path of docker as above, it runs normally.
The /usr/local/bin path is registered in .bash_profile and .profile.
Docker was launched as docker desktop on mac.
The Mac version is macOS monterey 12.2.
Update
In my case, the issue was that the path was not set in non-interactive non-login of ssh.
Because I was using zsh
I solved it by adding alias docker=/usr/local/bin/docker to /etc/zshenv .
I just installed docker for the first time and when the default virtualbox or 'docker-machine'(not sure what it is called I run into this error:
This is an excerpt
Checking connection to Docker...
Error creating machine: Error checking the host: Error checking and/or regenerat
ing the certs: There was an error validating certificates for host "192.168.99.1
01:2376": x509: certificate has expired or is not yet valid
You can attempt to regenerate them using 'docker-machine regenerate-certs [name]
'.
Be advised that this will trigger a Docker daemon restart which might stop runni
ng containers.
I tried using the docker-machine regenerate-certs [name] command and it seemed to work no errors were raised at least. Only when I attempted to run docker's hello world command this is the result I got.
docker: error during connect: Post http://%2F%2F.%2Fpipe%2Fdocker_engine/v1.39/c
ontainers/create: open //./pipe/docker_engine: The system cannot find the file s
pecified. 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.
See 'docker run --help'.
I searched up similar errors and found a few case where creating a new virtualbox/docker-machine(still don't know what its called) solved it but the same error that appeared with the default box showed up.
Error creating machine: Error checking the host: Error checking and/or regenerat

You can attempt to regenerate them using 'docker-machine regenerate-certs [name]
Afterwards I gave the docker-machine ls command a try in order to see if I could find something helpful. This is the output.

How can I fix it?
Try docker-machine regenerate-certs --client-certs.
Try this:
In your command prompt run:
docker-machine ls
it will return
NAME ACTIVE DRIVER STATE URL SWARM DOCKER ERRORS
<name> <status> <driver> <state> <url> <swarm> <docker> <errors>
get the <name> of the machine you want to run (if it's the first time you are running docker, then you have only one machine running and its name is default, in this example I will call it <name>)
then run:
docker-machine kill <name>
docker-machine create <name>
docker-machine env <name>
The last command will output more lines, copy the last one, in my case it was like this:
# eval $("C:\my\path\to\docker-machine.exe" env <name>)
then paste it in the command prompt without the # and run it, the problem should be fixed now.
You can check it by running docker-machine ls, if the problem is fixed, you should see no more messages under the ERROR column.
Furthermore, it is possible that the lines
docker-machine kill <name>
docker-machine create <name>
are not required if you have only one docker-machine existing and its <name> is default.
Maybe you can vi /etc/docker/daemon.json
use this setting:
{
"insecure-registries":[
"0.0.0.0/0"
]
}
then restart service:
service docker restart
and try again.

I have a Windows 7, and Authenticated proxy in my job...
Set the proxy in your environment before running the docker run command...
set HTTPS_PROXY=http://user:password#proxy_name_or_ip:proxy_port
For example
set HTTPS_PROXY=http://myusername:Password1#proxy.local:8080
For docker on windows, follow these steps to configure the proxy variables:
In powershell perform the following for HTTP_PROXY and HTTPS_PROXY:
[Environment]::SetEnvironmentVariable("HTTP_PROXY", "http://username:password#proxy:port/", [EnvironmentVariableTarget]::Machine)
Once the variables are set, restart the service with powershell:
Restart-Service docker
Edit: For Linux native installs of Docker using systemd, follow these steps to configure your proxy:
Create a systemd drop-in directory for the docker service:
$ sudo mkdir -p /etc/systemd/system/docker.service.d
Create a file called /etc/systemd/system/docker.service.d/http-proxy.conf that adds the HTTP_PROXY environment variable:
[Service]
Environment="HTTP_PROXY=http://proxy.example.com:80/"
Or, if you are behind an HTTPS proxy server, create a file called /etc/systemd/system/docker.service.d/https-proxy.conf that adds the HTTPS_PROXY environment variable:
[Service]
Environment="HTTPS_PROXY=https://proxy.example.com:443/"
If you have internal Docker registries that you need to contact without proxying you can specify them via the NO_PROXY environment variable:
[Service]
Environment="HTTP_PROXY=http://proxy.example.com:80/" "NO_PROXY=localhost,127.0.0.1,docker-registry.somecorporation.com"
Or, if you are behind an HTTPS proxy server:
[Service]
Environment="HTTPS_PROXY=https://proxy.example.com:443/" "NO_PROXY=localhost,127.0.0.1,docker-registry.somecorporation.com"
Flush changes:
$ sudo systemctl daemon-reload
Restart Docker:
$ sudo systemctl restart docker
Verify that the configuration has been loaded:
$ systemctl show --property=Environment docker
Environment=HTTP_PROXY=http://proxy.example.com:80/
Or, if you are behind an HTTPS proxy server:
$ systemctl show --property=Environment docker
Environment=HTTPS_PROXY=https://proxy.example.com:443/
For special characters in your password, you can use unicode to encode the characters:
If your original password was: F#o:o!B#ar$
The unicode equivalent would be: F%40o%3Ao%21B%23ar%24
After I restarted my windows i cannot connect to docker machine running in Oracle Virtual Box.
When i start Docker QuickStart Terminal every thing looks fine, it's coming up OK and it gives me this message:
docker is configured to use the default machine with IP 192.168.99.100
For help getting started, check out the docs at https://docs.docker.com
but when i do:
$ docker-machine ls
NAME ACTIVE DRIVER STATE URL SWARM DOCKER ERRORS
default - virtualbox Timeout
and:
λ docker images
An error occurred trying to connect: Get http://localhost:2375/v1.21/images/json: dial tcp 127.0.0.1:2375: ConnectEx tcp: No connection could be made because the target machine actively refused it.
also when i try to reinitialize my env., i get:
λ docker-machine env default
Error checking TLS connection: Error checking and/or regenerating the certs: There was an error validating certificates for host "192.168.99.100:2376": dial tcp 192.168.99.100:2376: i/o timeout
You can attempt to regenerate them using 'docker-machine regenerate-certs [name]'.
Be advised that this will trigger a Docker daemon restart which will stop running containers.
BTW, Regenerating certs also not helping.
Any idea?
Thanks.
Please try regenerating certificates manually by:
docker-machine --debug regenerate-certs -f default
and check for any errors to fix, then try again:
docker-machine --debug env default
If it's failing on ssh, copy and paste that command into terminal to see what's the problem by adding extra -vv.
If you've got:
debug1: connect to address 127.0.0.1 port 64368: Connection refused
then your machine isn't running (check by docker-machine ls), so try:
docker-machine start
Then try to ssh to it via:
docker-machine -D ssh default
After doing some research I found out that following workaround may solve the issue for now:
Open Network And Sharing Center
Click on Change Adapter Setting
See if you have any enabled adapters such as VPN or VM Ware network adapters.
Try to disable them and try to connect to your container one more time
If it didn't work while you have other adapters disabled, Restart your PC - in my case this worked for me.
What worked for me is this answer from the docker-machine repo:
docker-machine regenerate-certs --client-certs [name]
Basically, what expired is client certificates. The error message I get from docker-machine is similar to yours (i.e., no indication it's the client certs that need to be regenerated).
I fix it doing this:
Removed all host-only interfaces from my VirtualBox (VirtualBox → Preferences → Network → Host-only networks).
rmdir.exe --ignore-fail-on-non-empty ~/.docker/
docker-machine start
docker-machine env
eval $("C:\Program Files\Docker Toolbox\docker-machine.exe" env default) (added also at the end of my .bash_profile).
docker run hello-world ← now working
Inspired in this post.
Here is what worked for me. The first steps are similar to what Hazhir proposed, then followed by regenerate the certificates.
Open Network And Sharing Center.
Click on Change Adapter Setting.
Disable all active VMWare network adapters. Usually has explanation "VirtualBox Host-Only Ethernet Adapter".
Connect to your container by running docker-machine start.
Run docker-machine env. If you're like me then you'd get following error:
Error checking TLS connection: Error checking and/or regenerating the
certs: There was an error validating certificates for host
"192.168.99.100:2376": x509: certificate is valid for 192.168.99.101,
not 192.168.99.100
Which is good. Now all we need to do is to run
docker-machine regenerate-certs -f default
Then test it again with docker-machine env. If you get:
SET DOCKER_TLS_VERIFY=1
SET DOCKER_HOST=tcp://192.168.99.100:2376
SET DOCKER_CERT_PATH=C:\Users\Jay\.docker\machine\machines\default
SET DOCKER_MACHINE_NAME=default
REM Run this command to configure your shell:
REM FOR /f "tokens=*" %i IN ('docker-machine env') DO %i
Then you're all set. In my case I needed to start my virtual machine by running Docker Quickstart Terminal.
I have this problem too. Execute docker-machine regenerate-certs <vm-name> can not solve problem. I search Google the error info and find the solution below.
execute sudo ifconfig vboxnet0 up in terminal.
show docker machine state: docker-machine ls.
now STATE and URL are ok.
But restart the system this problem persists.
GitHub issues link I found is here.
It seems there is a bug in VirtualBox 5.1.24.
Just start the docker machine and then regenerate certificates
docker-machine start <machine-name>
docker-machine regenerate-certs <machine-name>
It works like a charm for me.
None of the answers here helped me. My problem occurred when I want to activate the shell of my virtual machine with eval $(docker-machine env default).
It was then trying to access the port 2376 which was closed, so I had to enter the shell of the VM through ssh and activate the following UFW rule:
sudo ufw allow 2376
The way I ensure being able to connect to my docker machines is by assigning them a fixed IP (and regenerating the certs only once) (no reboot needed)
After that, docker-machine ls always work.
My current script:
(replace %PRGS%\dm\latest by the path where docker-machine.exe is on your machine)
(make sure PATH include the latest /path/to/git/usr/bin, for commands like ssh to be available)
> more dmvbf.bat
#echo off
setlocal enabledelayedexpansion
set machine=%1
if "%machine%" == "" (
echo dmvbf expects a machine name
exit /b 1
)
set ipx=%2
if "%ipx%" == "" (
echo dmvbf x missing ^(for 192.168.x.y^)
exit /b 2
)
set ipy=%3
if "%ipy%" == "" (
echo dmvbf y missing ^(for 192.168.x.y^)
exit /b 3
)
%PRGS%\dm\latest\docker-machine.exe ssh %machine% "sudo sh -c 'echo \"kill \$(more /var/run/udhcpc.eth1.pid)\" | sudo tee /var/lib/boot2docker/bootsync.sh >/dev/null'"
%PRGS%\dm\latest\docker-machine ssh %machine% "sudo sh -c 'echo \"ifconfig eth1 192.168.%ipx%.%ipy% netmask 255.255.255.0 broadcast 192.168.%ipx%.255 up\" | sudo tee -a /var/lib/boot2docker/bootsync.sh >/dev/null'"
%PRGS%\dm\latest\docker-machine ssh %machine% "sudo chmod 755 /var/lib/boot2docker/bootsync.sh"
%PRGS%\dm\latest\docker-machine ssh %machine% "sudo cat /var/run/udhcpc.eth1.pid | xargs sudo kill"
%PRGS%\dm\latest\docker-machine ssh %machine% "sudo ifconfig eth1 192.168.%ipx%.%ipy% netmask 255.255.255.0 broadcast 192.168.%ipx%.255 up"
For instance:
dmvbf default 99 100
docker-machine regenerate-certs -f default
That will assign 192.168.99.100 to the docker machine 'default', and regenerate the certs once.
Then each time docker-machine ls is called, it will display the same IP for 'default'.
Try this way/workaround:
firstly make sure there are ca.pem, cert.pem, key.pem, ca-key.pem under $yourhome/.docker/machine/certs/ folder , for these lost four *.pem files, you can copy them from other places or maybe create them yourselves ( these four pem files are surely not correct at the beginning )
make sure the env set correctly in bash_profile, like:
export DOCKER_HOST=tcp://192.168.99.100:2376
export DOCKER_MACHINE_NAME=default
export DOCKER_TLS_VERIFY=1
export DOCKER_CERT_PATH=/Users/johnwang/.docker/machine/machines/default
rerun the cmd: docker-machine regenerate-certs default (maybe before run this, you need reopen the docker terminal)
Tried on docker toolbox on mac, and it works.
Finally some logs of the result:
Error checking TLS connection: Error checking and/or regenerating the certs: There was an error validating certificates for host "192.168.99.100:2376": x509: certificate signed by unknown authority
You can attempt to regenerate them using 'docker-machine regenerate-certs [name]'.
Be advised that this will trigger a Docker daemon restart which might stop running containers.

Hope it helps
also see my response here:https://github.com/docker/machine/issues/2808
In my case it was my FortiClient that caused the issue. After disabling it docker-machine env default worked fine again. I suggest you to check if there's any anti-virus program running in your system.
for me, running
docker-machine --debug regenerate-certs -f name_of_your_vm
worked just fine.
docker-machine version 0.16.1
virtualBox 6.0
also docker was configured to use the default machine with IP 192.168.99.100
I had the same error. I fixed it by open tcp port 2376 in network firewall.
The solution for my problem is taken from here:
https://github.com/docker/machine/issues/3845#issuecomment-271935924
Quote:
If you install docker-machine first time then you do not have in that
host a self-signed CA that will be used to generate your client
certificate and as many server certificates as machines you generate
later on. That CA is generated when you try to create a machine if
that CA is not yet created. So if you try to generate several servers
in parallel (by means of an script), then you’ll generate as many
self-signed (root) CA as docker createcommands, all of them being
written in the same location that seems to be messing up the
environment e.g. spreading out different ca.pem to the remote machines
that do match the final version, causing the cert.pem (host identity)
to be signed by a former ca.pem which no longer exist… or whatever
other abnormal situation.
To fix it, first of all you'll need to delete your existing
self-signed CA. This can be done by removing the folder
~/.docker/machine/certs (NOTE: Note this will force the creation of a
new self-signed CA for docker-machine to use and will yield your
existing machines to fail connecting to the daemon). This will make
your docker-machine to generate valid certificates again. Then, for my
use case I am creating the first machine in foreground and all the
rest of them are done in parallel. That will cause the creation of one
root self-signed CA in isolation and then will be used for further
docker-machine create commands. It worked like a charm!
The reason why I was able to ssh to the host is because there are a
different pair of keys for sshing generate per host that was not
bitten by this.
To sum up, this is what I ended up doing:
Find out what is the command that docker-machine is running. I was using it with gitlab-runner, So I had to run gitlab-runner in debug mode to see what command was it running on docker-machine.
then stop gitlab-runner: gitlab-runner stop
then delete the certificate: rm -rf ~/.docker/machine/certs
then run a single command (from step #1) to re-create the certs (remember - the reason this didn't work is because it was trying to create it multiple times)
then rerun gitlab-runner: gitlab-runner start
Worked for me!

docker-machine restart default. Done
Solved this issue in MacOS by installing Docker Desktop
brew uninstall docker
brew uninstall docker-machine
Then download Docker Desktop for mac https://docs.docker.com/desktop/mac/install/
Is there anyway to configure --allow-insecure-ssl for docker's deamon created with docker-machine.
commands:
docker-machine create --driver virtualbox dev
eval "$(docker-machine env dev)"
docker run myregistry:5000/busybox:latest echo 'hello world'
output:
Unable to find image 'myregistry:5000/busybox:latest' locally
2015/06/04 16:54:17 Error: v1 ping attempt failed with error: Get
https://myregistry:5000/v1/_ping: EOF. If this private
registry supports only HTTP or HTTPS with an unknown CA certificate,
please add `--insecure-registry myregistry:5000` to the
daemon's arguments. In the case of HTTPS, if you have access to the
registry's CA certificate, no need for the flag; simply place the CA
certificate at /etc/docker/certs.d/myregistry:5000/ca.crt
If you are running docker-machine version v0.2 stable, you can't set docker option in light way. But in next version v0.3 this problem was resolved with the creation parameters.
At this moment this feature it's on RC1,then you can use a version v0.3.0-RC-1 or wait for delivery the next stable version v0.3.0(tentatively Jun.16).
Then use parameter --engine-insecure-registry to set --allow-insecure-ssl for docker's daemon, for example:
docker-machine create --driver virtualbox --engine-insecure-registry myregistry:5000 dev
After that you can execute:
docker run myregistry:5000/busybox:latest echo 'hello world'
Additionally you can read about it on project doc.
If you want to add insecure registries to a docker-machine that is already created you can update the profile in the running docker VM.
Steps
SSH into your local docker VM.
note: if 'default' is not the name of your docker machine then substitute 'default' with your docker machine name
$ docker-machine ssh {machineName}
Open Docker profile
$ sudo vi /var/lib/boot2docker/profile
Add this line to the bottom of the profile file. If EXTRA_ARGS already exists, add the insecure registry flag to the EXTRA_ARGS. Substitute in the path[s] to your registries.
EXTRA_ARGS="
--insecure-registry myserver.pathTo.registry1:5000
--insecure-registry myserver.pathTo.registry2:5000
--insecure-registry myserver.pathTo.registry3:5000
"
Save the profile changes and 'exit' out of the docker-machine bash back to your machine. Then Restart Docker VM substituting in your docker-machine name
$ docker-machine restart {machineName}
Pull or push something from your registry to ensure it works
My Setup
docker-machine version : 0.6.0, build e27fb87
docker-machine driver : virtualbox
In case you want to add another registry once your docker-machine has already been created you will have to edit the configuration file:
vim ~/.docker/machine/machines/dev/config.json
Explained here: https://akrambenaissi.com/2015/11/17/addingediting-insecure-registry-to-docker-machine-afterwards/
env :
docker daemon :1.12.3
docker client :1.12.2
docker api :1.24
docker-machine :0.8.2
Before create machine
you can use the args to set one or multi insecure registry and registry mirrors .eg:
one registry
docker-machine create -d virtualbox --engine-insecure-registry hostname:5000 --engine-registry-mirror http://hostname:5000 n1
multi registrys
docker-machine create -d virtualbox --engine-insecure-registry hostname:5000 --engine-insecure-registry hostname:5001 --engine-registry-mirror http://hostname:5000 n1
After create the machine
you can edit the /var/lib/boot2docker/profile to add the registrys and mirrors
docker-machine ssh [machine-name]
vi /var/lib/boot2docker/profile
add the registry and mirrors to the EXTRA_ARGS
EXTRA_ARGS='
--label provider=virtualbox
--insecure-registry hostname:5000
--insecure-registry hostname:5001
--registry-mirror http://hostname:5000
--registry-mirror http://hostname:5001
now you need to restart the machine and check it
docker-machine restart [machine-name]
docker info
this method doesn`t work after create the machine
