description: Troubleshooting connectivity and certificate issues
keywords: beginner, getting started, FAQs, troubleshooting, Docker
title: Troubleshooting

Typically, the QuickStart works out-of-the-box, but some scenarios can cause problems.
## Example errors
You might get errors when attempting to connect to a machine (such as with `docker-machine env default`) or pull an image from Docker Hub (as with `docker run hello-world`).
The errors you get might be specific to certificates, like this:
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
Others explicitly suggest regenerating certificates:
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
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.
Or, indicate a network timeout, like this:
bash-3.2$ docker run hello-world
Unable to find image 'hello-world:latest' locally
Pulling repository docker.io/library/hello-world
Network timed out while trying to connect to https://index.docker.io/v1/repositories/library/hello-world/images. You may want to check your internet connection or if you are behind a proxy.
bash-3.2$
## Solutions
Here are some quick solutions to help get back on track. These examples assume the Docker host is a machine called `default`.
#### Regenerate certificates
Some errors explicitly tell you to regenerate certificates. You might also try this for other errors that are certificate and/or connectivity related.
$ docker-machine regenerate-certs default
Regenerate TLS machine certs? Warning: this is irreversible. (y/n): y
Regenerating TLS certificates
#### Restart the Docker host
$ docker-machine restart default
After the machine starts, set the environment variables for the command window.
$ eval $(docker-machine env default)
Run `docker-machine ls` to verify that the machine is running and that this command window is configured to talk to it, as indicated by an asterisk for the active machine (__*__).
$ docker-machine ls
NAME ACTIVE DRIVER STATE URL SWARM DOCKER ERRORS
default * virtualbox Running tcp://192.168.99.101:2376 v1.10.1
#### Stop the machine, remove it, and create a new one.
$ docker-machine stop default
Stopping "default"...
Machine "default" was stopped.
$ docker-machine rm default
About to remove default
Are you sure? (y/n): y
Successfully removed default
You can use the `docker-machine create` command with the `virtualbox` driver to create a new machine called `default` (or any name you want for the machine).
$ docker-machine create --driver virtualbox default
Running pre-create checks...
(default) Default Boot2Docker ISO is out-of-date, downloading the latest release...
(default) Latest release for github.com/boot2docker/boot2docker is v1.10.1
(default) Downloading
...
Docker is up and running!
To see how to connect your Docker Client to the Docker Engine running on this virtual machine, run: docker-machine env default
Set the environment variables for the command window.
$ eval $(docker-machine env default)
Run `docker-machine ls` to verify that the new machine is running and that this command window is configured to talk to it, as indicated by an asterisk for the active machine (__*__).
<a name="machine-http-proxy-solutions"></a>
## HTTP proxies and connectivity errors
A special brand of connectivity errors can be caused by HTTP proxy. If you install Docker Toolbox on a system using a virtual private network (VPN) that uses an HTTP proxy (such as a corporate network), you might encounter errors when the client attempts to connect to the server.
Here are examples of this type of error:
$ docker run hello-world
An error occurred trying to connect: Post https://192.168.99.100:2376/v1.20/containers/create: Forbidden
$ docker run ubuntu echo "hi"
An error occurred trying to connect: Post https://192.168.99.100:2376/v1.20/containers/create: Forbidden
### Configure HTTP proxy settings on Docker machines
When Toolbox creates virtual machines (VMs) it runs `start.sh`, where it gets values for `HTTP_PROXY`, `HTTPS_PROXY`, and `NO_PROXY`, and passes them as `create` options to create the `default machine`.
You can reconfigure HTTP proxy settings for private networks on already-created Docker machines, such as the `default` machine, then change the configuration when you are using the same system on a different network.
Alternatively, you can modify proxy settings on your machine(s) manually through the configuration file at `/var/lib/boot2docker/profile` inside the VM, or configure proxy settings as a part of a `docker-machine create` command.
Both solutions are described below.
#### Update /var/lib/boot2docker/profile on the Docker machine
One way to solve this problem is to update the file `/var/lib/boot2docker/profile` on an existing machine to specify the proxy settings you want.
This file lives on the VM itself, so you need to `ssh` into the machine, then edit and save the file there.
You can add your machine addresses as values for a `NO_PROXY` setting, and also specify proxy servers that you know about and you want to use. Typically setting your Docker machine URLs to `NO_PROXY` solves this type of connectivity problem, so that example is shown here.
1. Use `ssh` to log in to the virtual machine. This example logs in to the
`default` machine.
$ docker-machine ssh default
docker@default:~$ sudo vi /var/lib/boot2docker/profile
2. Add a `NO_PROXY` setting to the end of the file similar to the example below.
# replace with your office's proxy environment
export "HTTP_PROXY=http://PROXY:PORT"
export "HTTPS_PROXY=http://PROXY:PORT"
# you can add more no_proxy with your environment.
export "NO_PROXY=192.168.99.*,*.local,169.254/16,*.example.com,192.168.59.*"
3. Restart Docker.
After you modify the `profile` on your VM, restart Docker and log out of the machine.
docker@default:~$ sudo /etc/init.d/docker restart
docker@default:~$ exit
Re-try Docker commands. Both Docker and Kitematic should run properly now.
When you move to a different network (for example, leave the office's corporate network and return home), remove or comment out these proxy settings in `/var/lib/boot2docker/profile` and restart Docker.
#### Create machines manually using --engine env to specify proxy settings
Rather than reconfigure automatically-created machines, you can delete them and create your `default` machine and others manually with the `docker-machine create` command, using the `--engine env` flag to specify the proxy settings you want.
Here is an example of creating a `default` machine with proxies set to `http://example.com:8080` and `https://example.com:8080`, and a `N0_PROXY` setting for the server `example2.com`.
docker-machine create -d virtualbox \
--engine-env HTTP_PROXY=http://example.com:8080 \
--engine-env HTTPS_PROXY=https://example.com:8080 \
--engine-env NO_PROXY=example2.com \
default
To learn more about using `docker-machine create`, see the [create](../../machine/reference/create.md) command in the [Docker Machine](../../machine/overview.md) reference.

description: How to install Toolbox on Mac

title: Install Docker Toolbox on macOS
---
Docker Toolbox provides a way to use Docker on older Macs
that do not meet
minimal system requirements for [Docker Desktop for Mac](../docker-for-mac/index.md).
## What you get and how it works
Docker Toolbox includes the following Docker tools:
* Docker CLI client for running Docker Engine to create images and containers
* Docker Machine so you can run Docker Engine commands from macOS terminals
* Docker Compose for running the `docker-compose` command
* Kitematic, the Docker GUI
* the Docker QuickStart shell preconfigured for a Docker command-line environment
* Oracle VM VirtualBox
Because the Docker Engine daemon uses Linux-specific
kernel features, you can't run Docker Engine natively on
macOS with Docker Toolbox. Instead, you must use the
Docker Machine command, `docker-machine`, to create and
attach to a small Linux VM on your machine. This VM hosts
Docker Engine for you on your Mac.
>**Tip**: One of the advantages of the newer
[Docker Desktop for Mac](../docker-for-mac/index.md) solution is that
it uses native virtualization and does not require
VirtualBox to run Docker.
## Step 1: Check your version
Your Mac must be running macOS 10.8 "Mountain Lion" or newer to run Docker
software. To find out what version of the OS you have:
1. Choose **About this Mac** from the Apple menu.
The version number appears directly below the words `macOS`.
2. If you have the correct version, go to the next step.
If you aren't using a supported version, you could consider upgrading your
operating system.
If you have macOS 10.14 Mojave or newer, consider using [Docker Desktop for
Mac](/docker-for-mac/) instead. It runs natively on the Mac, so there is no
need for a pre-configured Docker QuickStart shell. It uses the native macOS
Hypervisor framework for virtualization, instead of Oracle VirutalBox. Full
install prerequisites are provided in the Docker Desktop for Mac topic in [Docker
Desktop for Mac](/docker-for-mac/#what-to-know-before-you-install).
## Step 2: Install Docker Toolbox
> **Note**: Docker are no longer maintaining the download.docker.com url for
> Docker Toolbox, therefore an unsigned warning (verified publisher dialog) is
> displayed during the installation process.
1. To download the latest version of Docker Toolbox, go to [Toolbox
Releases](https://github.com/docker/toolbox/releases) and download the
latest `.pkg` file.
2. Install Docker Toolbox by double-clicking the package or by right-clicking
and choosing "Open" from the pop-up menu.
The installer launches an introductory dialog, followed by an overview of what's installed.
![Install Docker Toolbox](images/mac-welcome-page.png)
3. Press **Continue** to install the toolbox.
The installer presents you with options to customize the standard
installation.
![Standard install](images/mac-page-two.png)
By default, the standard Docker Toolbox installation:
* installs binaries for the Docker tools in `/usr/local/bin`
* makes these binaries available to all users
* updates any existing Virtual Box installation
For now, don't change any of the defaults.
4. Press **Install** to perform the standard installation.
The system prompts you for your password.
![Password prompt](images/mac-password-prompt.png)
5. Provide your password to continue with the installation.
When it completes, the installer provides you with some
shortcuts. You can ignore this for now and click **Continue**.
![Quickstart](images/mac-page-quickstart.png)
Then click **Close** to finish the installer.
![All finished](images/mac-page-finished.png)
## Step 3: Verify your installation
To run a Docker container, you:
* create a new (or start an existing) Docker Engine host running
* switch your environment to your new VM
* use the `docker` client to create, load, and manage containers
Once you create a machine, you can reuse it as often as you like. Like any
Virtual Box VM, it maintains its configuration between uses.
1. Open the **Launchpad** and locate the Docker Quickstart Terminal icon.
![Launchpad](images/applications_folder.png)
2. Click the icon to launch a Docker Quickstart Terminal window.
The terminal does a number of things to set up Docker Quickstart Terminal for you.
```

```
3. Click your mouse in the terminal window to make it active.
If you aren't familiar with a terminal window, here are some quick tips.
![Terminal](images/terminal.png)
The prompt is traditionally a `$` dollar sign. You type commands into the
*command line* which is the area after the prompt. Your cursor is indicated
by a highlighted area or a `|` that appears in the command line. After
typing a command, always press RETURN.
4. Type the `docker run hello-world` command and press RETURN.
The command does some work for you, if everything runs well, the command's
output looks like this:
$ docker run hello-world
Unable to find image 'hello-world:latest' locally
latest: Pulling from library/hello-world
535020c3e8ad: Pull complete
af340544ed62: Pull complete
Digest: sha256:a68868bfe696c00866942e8f5ca39e3e31b79c1e50feaee4ce5e28df2f051d5c
Status: Downloaded newer image for hello-world:latest
Hello from Docker.
This message shows that your installation appears to be working correctly.
To generate this message, Docker took the following steps:
1. The Docker Engine CLI client contacted the Docker Engine daemon.
2. The Docker Engine daemon pulled the "hello-world" image from the Docker Hub.
3. The Docker Engine daemon created a new container from that image which runs the
executable that produces the output you are currently reading.
4. The Docker Engine daemon streamed that output to the Docker Engine CLI client, which sent it
to your terminal.
To try something more ambitious, you can run an Ubuntu container with:
$ docker run -it ubuntu bash
Share images, automate workflows, and more with a free Docker Hub account:
https://hub.docker.com
For more examples and ideas, visit:
https://docs.docker.com/userguide/
## Optional: Add shared directories
By default, Toolbox only has access to the `/Users` directory and mounts it into
the VMs at `/Users`. If your project lives elsewhere or needs access to other
directories on the host filesystem, you can add them.
### Use the VirtualBox GUI
You can configure shared folders in the VirtualBox UI.
1. Open the VirtualBox UI.
2. Click the **Settings** gear, then go to **Shared Folders**.
3. Select any existing listing under **Machine Folders**, then
click the **+** icon.
* Choose the **Folder Path** on the host, enter the **Folder Name**
for within the VM (or take the default, which is the same name
as on the host), and configure any additional options you need.
* Choose **Auto-mount** if you want the folder to automatically
be mounted into the VM, and choose **Make Permanent** for it
to be considered a permanently shared folder.
4. Click **OK** to add the new folder to the Shared Folders list.
5. Click **OK** again to save your changes and exit the Settings dialog.
### Use the command line
You can configure shared folders using a command like the following:
```bash
$ mount -t vboxsf -o uid=1000,gid=50 your-other-share-name /some/mount/location
```
This command mounts `/some/mount/location` into the VM at `/your-other-share-hame`,
owned by UID 1000 and GID 50.
> **Note**: The autommount and permanent mount options are not supported using
> the command line.
## How to uninstall Toolbox
Removing Toolbox involves removing all the Docker components it includes.
A full uninstall also includes removing the local and remote machines
you created with Docker Machine. In some cases, you might want to keep
machines created with Docker Machine.
For example, if you plan to re-install Docker Machine as a part of
Docker Desktop for Mac you can continue to manage those machines through
Docker. Or, if you have remote machines on a cloud provider and you
plan to manage them using the provider, you wouldn't want to remove
them. So the step to remove machines is described here as optional.
To uninstall Toolbox on a Mac, do the following:
1. List your machines.
```
$ docker-machine ls
NAME ACTIVE DRIVER STATE URL SWARM
dev * virtualbox Running tcp://192.168.99.100:2376
my-docker-machine virtualbox Stopped
default virtualbox Stopped
```
2. Optionally, remove each machine. For example:
```
$ docker-machine rm my-docker-machine
Successfully removed my-docker-machine
```
This step is optional because if you plan
to re-install Docker Machine as a part
of [Docker Desktop for Mac](../docker-for-mac/index.md), you can import and
continue to manage those machines through Docker.
3. In your "Applications" folder, remove the "Docker" directory,
which contains "Docker Quickstart Terminal" and "Kitematic".
4. Run the following in a command shell to fully remove Kitematic:
```
$ rm -fr ~/Library/Application\ Support/Kitematic
```
5. Remove the `docker`, `docker-compose`, and `docker-machine` commands from
the `/usr/local/bin` folder. Docker Desktop for Mac and Brew may also have
installed them; in case of doubt leave them, or reinstall them via Brew, or
rerun Docker Desktop for Mac (no need to reinstall it).
```
$ rm -f /usr/local/bin/docker
$ rm -f /usr/local/bin/docker-compose
$ rm -f /usr/local/bin/docker-machine
```
6. Optionally, remove the `~/.docker/machine` directory.
This directory stores some configuration and/or state, such as information
about created machines and certificates.
7. Uninstall Oracle VirtualBox, which is installed as a part of the
Toolbox install.
## Next steps
* Try the [Get started](../get-started/index.md) tutorial.
* Dig in deeper with [more tutorials and examples](../engine/tutorials/index.md) on building images, running containers, networking, managing data, and storing images on Docker Hub.
* [Learn about Kitematic](../kitematic/userguide.md)
* [Learn about Docker Machine](../machine/overview.md)
* [Learn about Docker Compose](../compose/index.md)

title: Install Docker Toolbox on Windows

Docker Toolbox provides a way to use Docker on Windows systems that do not meet
minimal system requirements for the [Docker Desktop for Windows](../docker-for-windows/index.md)
app.
## What you get and how it works
Docker Toolbox includes the following Docker tools:
* Docker CLI client for running Docker Engine to create images and containers
* Docker Machine so you can run Docker Engine commands from Windows terminals
* Docker Compose for running the `docker-compose` command
* Kitematic, the Docker GUI
* the Docker QuickStart shell preconfigured for a Docker command-line environment
* Oracle VM VirtualBox
Because the Docker Engine daemon uses Linux-specific
kernel features, you can't run Docker Engine natively
on Windows. Instead, you must use the Docker Machine
command, `docker-machine`, to create and attach to a
small Linux VM on your machine. This VM hosts Docker Engine
for you on your Windows system.
>**Tip**: One of the advantages of the newer
[Docker Desktop for Windows](../docker-for-windows/index.md) solution is that
it uses native virtualization and does not require
VirtualBox to run Docker.
## Step 1: Check your version
To run Docker, your machine must have a 64-bit operating system running Windows 7 or higher. Additionally, you must make sure that virtualization is enabled on your machine.
To verify your machine meets these requirements, do the following:
1. Right click the windows message and choose **System**.
If you aren't using a supported version, you could consider upgrading your
operating system.
If you have a recent version of Windows,
consider using [Docker Desktop for Windows](/docker-for-windows) instead. It runs
natively on the Windows, so there is no need for a pre-configured Docker
QuickStart shell. It also uses Hyper-V for virtualization, so the
instructions below for checking virtualization will be out of date for newer
Windows systems. Full install prerequisites are provided in the Docker Desktop for
Windows topic in [What to know before you
install](/docker-for-windows/#what-to-know-before-you-install).
2. Make sure your Windows system supports Hardware Virtualization Technology and that virtualization is enabled.
<br>
**For Windows 10**
Run [Speccy](https://www.piriform.com/speccy){: target="_blank" rel="noopener" class="_"}, and look at the CPU information.
<br>
**For Windows 8 or 8.1**
Choose **Start > Task Manager** and navigate to the **Performance** tab.
Under **CPU** you should see the following:
![Release page](images/virtualization.png)
If virtualization is not enabled on your system, follow the manufacturer's instructions for enabling it.
<br>
**For Windows 7**
Run a tool like the [Microsoft® Hardware-Assisted Virtualization Detection Tool](https://www.microsoft.com/en-us/download/details.aspx?id=592){: target="_blank" rel="noopener" class="_"} or [Speccy](https://www.piriform.com/speccy){: target="_blank" rel="noopener" class="_"}, and follow the on-screen instructions.
<br><br>
3. Verify your Windows OS is 64-bit (x64)
How you do this verification depends on your Windows version.
For details, see the Windows article [How to determine whether
a computer is running a 32-bit version or 64-bit version of the
Windows operating system](https://support.microsoft.com/en-us/kb/827218).
## Step 2: Install Docker Toolbox
In this section, you install the Docker Toolbox software and several "helper" applications. The installation adds the following software to your machine:
* Docker Client for Windows
* Docker Toolbox management tool and ISO
* Oracle VM VirtualBox
* Git MSYS-git UNIX tools
If you have a previous version of VirtualBox installed, do not reinstall it with the Docker Toolbox installer. When prompted, uncheck it.
If you have Virtual Box running, you must shut it down before running the
installer.
> **Note**: Docker no longer maintains the download.docker.com url for
> Docker Toolbox, therefore an unsigned warning (verified publisher dialog) is
> displayed during the installation process.
1. To download the latest version of Docker Toolbox, go to [Toolbox
Releases](https://github.com/docker/toolbox/releases) and download the
latest `.exe` file.
2. Install Docker Toolbox by double-clicking the installer.
The installer launches the "Setup - Docker Toolbox" dialog.
If Windows security dialog prompts you to allow the program to make a
change, choose **Yes**. The system displays the **Setup - Docker Toolbox for
Windows** wizard.
![Release page](images/installer_open.png)
3. Press **Next** to accept all the defaults and then **Install**.
Accept all the installer defaults. The installer takes a few minutes to install all the components:
4. When notified by Windows Security the installer will make changes, make sure you allow the installer to make the necessary changes.
When it completes, the installer reports it was successful:
![Success](images/finish.png)
5. Uncheck "View Shortcuts in File Explorer" and press **Finish**.
## Step 3: Verify your installation
The installer adds Docker Toolbox, VirtualBox, and Kitematic to your
**Applications** folder. In this step, you start Docker Toolbox and run a simple
Docker command.
1. On your Desktop, find the Docker QuickStart Terminal icon.
![Desktop](images/icon-set.png)
2. Click the Docker QuickStart icon to launch a pre-configured Docker Toolbox terminal.
If the system displays a **User Account Control** prompt to allow VirtualBox to make changes to your computer. Choose **Yes**.
The terminal does several things to set up Docker Toolbox for you. When it is done, the terminal displays the `$` prompt.
![Desktop](images/b2d_shell.png)
The terminal runs a special `bash` environment instead of the standard Windows command prompt. The `bash` environment is required by Docker.
3. Make the terminal active by clicking your mouse next to the `$` prompt.
If you aren't familiar with a terminal window, here are some quick tips.

The prompt is traditionally a `$` dollar sign. You type commands into the
*command line* which is the area after the prompt. Your cursor is indicated
by a highlighted area or a `|` that appears in the command line. After
typing a command, always press RETURN.
4. Type the `docker run hello-world` command and press RETURN.
The command does some work for you, if everything runs well, the command's
output looks like this:
$ docker run hello-world
Unable to find image 'hello-world:latest' locally
Pulling repository hello-world
91c95931e552: Download complete
a8219747be10: Download complete
Status: Downloaded newer image for hello-world:latest
Hello from Docker.
This message shows that your installation appears to be working correctly.
To generate this message, Docker took the following steps:
1. The Docker Engine CLI client contacted the Docker Engine daemon.
2. The Docker Engine daemon pulled the "hello-world" image from the Docker Hub.
(Assuming it was not already locally available.)
3. The Docker Engine daemon created a new container from that image which runs the
executable that produces the output you are currently reading.
4. The Docker Engine daemon streamed that output to the Docker Engine CLI client, which sent it
to your terminal.
To try something more ambitious, you can run an Ubuntu container with:
$ docker run -it ubuntu bash

## Looking for troubleshooting help?
Typically, the above steps work out-of-the-box, but some scenarios can cause problems. If your `docker run hello-world` didn't work and resulted in errors, check out [Troubleshooting](faqs/troubleshoot.md) for quick fixes to common problems.
A Windows specific problem you might encounter relates to the NDIS6 host network filter driver, which is known to cause issues on some Windows
versions. For Windows Vista systems and newer, VirtualBox installs NDIS6 driver by default. Issues can range from system slowdowns to networking problems for the virtual machine (VM). If you notice problems, **re-run the Docker Toolbox installer**, and select the option to _**install VirtualBox with the NDIS5 driver**_.
## Optional: Add shared directories
By default, Toolbox only has access to the `C:\Users` directory and mounts it into
the VMs at `/c/Users`.
> **Note**: Within the VM path, `c` is lowercase and the `Users` is capitalized.
If your project lives elsewhere or needs access to other
directories on the host filesystem, you can add them, using the VirtualBox UI.
1. Open the VirtualBox UI.
2. Click the **Settings** gear, then go to **Shared Folders**.
3. Select any existing listing under **Machine Folders**, then
click the **+** icon.
* Choose the **Folder Path** on the host, enter the **Folder Name**
for within the VM (or take the default, which is the same name
as on the host), and configure any additional options you need.
* Choose **Auto-mount** if you want the folder to automatically
be mounted into the VM, and choose **Make Permanent** for it
to be considered a permanently shared folder.
4. Click **OK** to add the new folder to the Shared Folders list.
5. Click **OK** again to save your changes and exit the Settings dialog.
## How to uninstall Toolbox
Removing Toolbox involves removing all the Docker components it includes.
A full uninstall also includes removing the local and remote machines you created with Docker Machine. In some cases, you might want to keep machines created with Docker Machine.
For example, if you plan to re-install Docker Machine as a part of Docker Desktop for Windows you can continue to manage those machines through Docker. Or, if you have remote machines on a cloud provider and you plan to manage them using the provider, you wouldn't want to remove them. So the step to remove machines is described here as optional.
To uninstall Toolbox on Windows, do the following:
1. List your machines.
```
$ docker-machine ls
NAME ACTIVE DRIVER STATE URL SWARM
dev * virtualbox Running tcp://192.168.99.100:2376
my-docker-machine virtualbox Stopped
default virtualbox Stopped
```
2. Optionally, remove each machine. For example:
```
$ docker-machine rm my-docker-machine
Successfully removed my-docker-machine
```
This step is optional because if you plan to re-install Docker Machine as a
part of [Docker Desktop for Windows](../docker-for-windows/index.md), you can
import and continue to manage those machines through Docker.
3. Uninstall Docker Toolbox using Window's standard process for uninstalling programs through the control panel (programs and features).
>**Note**: This process does not remove the `docker-install.exe` file. You must delete that file yourself.
5. Optionally, remove the
`C:\Users\<your-user>\.docker` directory.
If you want to remove Docker entirely, you
can verify that the uninstall removed
the `.docker` directory under your user path.
If it is still there, remove it manually.
This directory stores some Docker
program configuration and state, such as
information about created machines and
certificates. You usually don't need to remove this directory.
6. Uninstall Oracle VirtualBox, which is
installed as a part of the Toolbox install.
